AN AUDIENCE ANALYSIS OF FACTORS CONTRIBUTING TO
AFRICAN-AMERICAN AND WHITE TEENS' PREGNANCY HEALTH BELIEFS:
IMPLICATIONS FOR MASS MEDIATED HEALTH CAMPAIGNS
(STUDENT PAPER)
ABSTRACT
Health professionals generally view the disparate health status of
minority populations as a direct effect of socioeconomic factors. This
view does not explain, however, why the infant mortality rate for
well-educated African-American women is considerably higher than for
less-educated Caucasian women. Further, this view has spurred largely
unsuccessful mass media campaigns to address this problem.
High school women were surveyed in this extensive audience analysis, thus
identifying cognitive and affective factors that lead to
African-American
and white teens' pregnancy health beliefs. Important implications
for
mass mediated public health campaigns that address the black infant
mortality problem are provided.
AN AUDIENCE ANALYSIS OF FACTORS CONTRIBUTING TO
AFRICAN-AMERICAN AND WHITE TEENS' PREGNANCY HEALTH BELIEFS:
IMPLICATIONS FOR MASS MEDIATED HEALTH CAMPAIGNS
Introduction
The disparate health status of minority populations is one of our most
serious problems in the United States. In 1989, the United States
Secretary of Health and Human Services Task Force on Black and Minority
Health identified infant mortality as one the most important health
priority concerns based on high risk factors associated with minority
populations (Office of Minority Health [OMH], 1989, p. 1). Infant
mortality is a critical health index, considered to be "the primary
indicator of the overall health status of nations" because it is associated
with access to basic needs such as "food, shelter, education, sanitation,
and health care; and second, it is relatively easy to monitor with
basic
vital statistics collected in all states" (Indiana State Board of
Health
Report [ISBH], 1989, p. 1).
Major risk factors associated with infant mortality include smoking and
substance abuse during pregnancy, late or no prenatal care, adolescent
pregnancy, and poor dietary habits. All of these factors contribute to
having a low birthweight baby (weighing less than 5 pounds, 8 ounces at
birth), which is "the most significant contributor" to infant mortality
(ISBH, 1989, p. 5). Further, pre-term babies that survive are at
greater
risk of dying before their first birthday or of developing serious
long-term disabilities.
Health professionals report that seeking early and regular prenatal care
(beginning in the first trimester and continuing throughout pregnancy)
reduces the risk of having a low birthweight baby and subsequent infant
mortality, not only because of the medical benefits, but also because
of
the important prevention education provided during those visits, which
may
improve the likelihood of having a healthy baby (OMH, 1990; Public
Health
Centers for Disease Control [PHSCDC], 1988; St. John & Winston, 1989;
Uni
ted States Department of Health and Human Services, 1989). Of course,
women should engage in healthy activities before they conceive, but
changing health behavior during pregnancy also can improve pregnancy
outcome significantly. A primary goal, then, is to persuade women to
obtain prenatal care early in their pregnancy.
There is no doubt that limited access to health care services and lack of
medical insurance coverage are formidable obstacles to obtaining
prenatal
care services (Starr, 1982; OMH, 1989). Yet statistics indicate that
lack
of prenatal care is prevalent among many African-American women, not
just
those who are in typically high risk sociodemographic populations.
This
claim is supported by the Indiana State Board of Health Report (1989)
which
showed that 81.4 percent of white women over 20 who had more than thirteen
years of education received adequate prenatal care in 1988, as opposed to
only 59.2 percent of black women in the same sociodemographic group.
Further, nearly twice as many black women (19.5 percent) received
inadequate
prenatal care than did white women (11.7 percent ) in poorly
educated populations that
same year. It appears that lack of adequate prenatal care is a
significant precursor of
infant mortality among black women, regardless of socioeconomic
status.
Theoretical Frameworks for Examining Health Behavior
The Demographic Model and Mass Media Campaigns
Although there is no doubt that demographic variables, (i.e., race,
income, education) affect health behavior, there are many other important
contributing factors not revealed by the way in which health
statistics
typically are reported. Nevertheless, many health studies continue to
focus on demographic differences as key correlates of health status and
health-seeking behavior. For example, government and other health
studies
illustrate pregnancy outcome differences through sociodemographic
predictor
variables such as maternal age, marital status, income and educational
level, and race (Centers for Disease Control, 1989; Lia-Hoagberg et
al.,
1990; ISBH, 1989).
This emphasis on sociodemographic factors has a significant impact on
health communication research. Many studies use samples representing
lower
sociodemographic populations to analyze health behavior. Additionally,
the demographic model serves as the foundation for many public health
campaigns in the mass media, because statistical analyses of health
status
indicate that individuals with lower education and income levels are
in
greater need of health education. Consequently, the prevailing
strategy
has been to disseminate accurate health messages to society's
"information
poor," with the belief that increased knowledge will result in
healthier
behavior.
Unfortunately, few public health campaigns have succeeded at changing
targeted individuals' health behavior and attitudes (Atkin, 1990; Rice &
Atkin, 1989). One explanation, the knowledge gap hypothesis, suggests
that
low socioeconomic status and low education level are responsible for campaign
failures because these factors create access and comprehension
barriers for some
populations (Brown, Ettema & Luepker, 1981; Donohue, Tichenor & Olien,
1975; Gaziano,
1983; Izard, 1985; Tichenor, Donohue & Olien, 1970). Therefore, the
infusion of mass
media information in high socioeconomic subgroups (who subsequently
share a higher
education level) creates a gap in knowledge because those in higher
socioeconomic groups
will acquire the information more efficiently than those in lower
socioeconomic groups
with less education.
Although important, the knowledge gap hypothesis does not provide answers
for why those in lower socioeconomic levels who do receive and recall
information from public health campaigns do not comply with campaign
recommendations. For example, the knowledge gap hypothesis does not
explain why better educated African-American women are less likely to seek
prenatal care than less educated white women: In 1988, 72.4 percent
of
white women with only a high school education received adequate
prenatal
care while only 59.2 percent of black women who have completed at
least one
year of college received adequate care (ISBH, 1989).
Another reason public health campaigns may fail to reach targeted
populations is that some individuals' perceptions of doctors and the health
care setting may create powerful barriers to seeking health care. This
has significant implications for health messages, because discomfort
with
doctors and the clinical setting may prevent an individual from
complying
with public health campaign appeals. This discomfort creates
communication
barriers in the clinical setting, and ultimately prevents the successful
delivery of health care (Arntson, 1989). Therefore, those who are
uncomfortable with doctors or other health professionals are unreceptive to
public health campaigns that recommend seeking care in a medical setting
(Pendleton & Hasler, 1983).
Another explanation for campaign failures is offered by Anderson (1989),
who suggests that public health campaigns typically focus on creating
awareness rather than teaching skills that will enable individuals to
change behavior. Anderson presents Bandura's self-efficacy theory as a
framework for his argument. Self-efficacy theory asserts that by
providing
information designed to empower people to engage in a recommended action,
those who typically avoid particular behaviors will gain the
psychological
and cognitive skills necessary to change. But although self-efficacy
theory is a useful concept for encouraging compliance with message
appeals,
it does not provide a mechanism for attracting those who do not perceive
they are engaging in unhealthy behavior.
Additionally, one line of research focuses on text features of messages
to explain why people do not absorb information. For example,
reducing
sentence, word, and paragraph length, or improving the visual
presentation
of a message, may help simplify a text, rendering it more
understandable to
a broader audience (for a review, see Rowan, 1988). Though important to
consider when explaining intellectually challenging information, these
strategies based on readability and organization do not offer methods
for
gaining the attention of an uninvolved audience.
Clearly, the widely accepted demographic explanation for disparate health
status does not provide a complete conceptual model for understanding
health behavior. And theories that advocate specific message features do
not address fully the issue of audience involvement. Indeed, there
are
many intervening variables that are important to consider in the
development of effective public health campaigns.
A Review of Health Beliefs and Behavior Models
The questions that remain unexplained by the discussions of health
behavior thus far are: (a) Why do some people continue to engage in
behavior that contradicts what orthodox medicine views as healthful,
specifically, why do some women fail to seek prenatal care; and (b) Why do
some individuals fail to attend to and assimilate relevant information
received through mass media channels? The primary reason public health
campaigns often fail is that they are not informed by a comprehensive
model
of health behavior (Kasch, 1983; Pettigrew & Logan, 1988). Health
professionals' efforts are not framed by theory that explains why people
differently incorporate information gleaned through mass media and
interpersonal channels, and how this information affects their
health-seeking behavior.
It is true that many health communication researchers today present
overarching theories of attitudes, cognition, motivation and behavior to
explain health outcomes (for example, see Anderson, 1989; Marin,
Narin,
Perez-Stable, Otero-Sabogal, & Sabogal, 1990; Reardon, 1988). These
models, however, do not provide a conceptual framework to demonstrate
relationships among mediating variables, including demographics, and
health
behavior. For example, some models such as attitude-behavior models
described by Ajzen's theory of planned behavior (1985), and Fishbein and
Ajzen's theory of reasoned action, are based on determinant attitudes
toward particular health behaviors (for a review, see Fishbein, Ajzen &
McArdle, 1980; and O'Keefe, 1990). These theoretical models, based on
persuasion and attitudinal change research, may offer an overly
simplistic
approach because they fail to explain how situational factors
important to
the development of health beliefs shape individuals' health behavior.
Additionally, these models do not explain the actions of audiences with
low
involvement with the health message, e.g., those who do not see themselves
as a target for the message or generally do not think about the
consequences of their behavior.
There are some models that provide a more comprehensive view of factors
that influence health behavior. These current models do not, however,
provide explanations for why some factors may be more important than
others
when it comes to health care decision-making. One such model, the Health
Beliefs Model (HBM), has been adapted and readapted by many health
researchers as a multidimensional instrument to predict health behavior
(Becker, Kirscht, Haefner, & Drachman, 1979; Eisen, Zellman, &
McAlister,
1985; for a review, see Janz & Becker, 1984). The HBM focuses on four
perceptual measures that affect the probability that an individual will
engage in preventive health behavior: perceived susceptibility to an
illness, perceived seriousness of contracting an illness; perceived
benefits of the preventive behavior; and perceived costs of the preventive
behavior. Several researchers have used the model successfully to
predict
compliance with specific medical recommendations, such as Shatz's
study of
diabetic patients' medical compliance patterns (1988).
The HBM has proved helpful in predicting behavioral outcomes and it
suggests some important correlates of health behavior. Often, however,
studies employing the Health Beliefs Model are limited in scope because
of
the assumptions inherent in the HBM. First, the model assumes that
people
make conscious decisions about their health behavior, while in real
life,
people may choose to avoid the decision-making process altogether.
Second,
most tests of this model focus on specific health behaviors as dependent
measures, such as beliefs associated with avoiding fertility control
or
using fertility control, rather than long-term dispositional,
attitudinal
variables that underlie these behaviors. This makes the HBM a
difficult
model to use for generalizing and predicting future behavior in other
health contexts. Third, the model offers no explanations for how beliefs
about susceptibility to illness, seriousness of health outcomes, and
benefits and costs of desired behavior develop over time.
For the purpose of this study, one key limitations of current health
beliefs models is that they describe people's beliefs about their own
health.
Rather, I am interested in exploring individuals' beliefs about how their
actions affect
the health of another human being. Specifically, a pregnant woman
may have different
beliefs and attitudes about her own health and that of the developing
fetus. In fact,
several studies have shown that teenaged and single mothers
frequently have highly
ambivalent feelings about being pregnant (Eisen et al, 1985; Tinsley &
Holtgrave, 1989).
These ambivalent feelings sometimes are associated with efforts to
ignore the developing
fetus or to engage in behavior that reduces that likelihood of
having a healthy baby.
The Proposed Mediated Effects Model of Pregnancy Health Behavior
There are at least two models that can account for pregnancy behavior.
Extant studies offer support for a direct effects model and a mediated
effects
model. The direct effects model suggests that one's membership in a
particular
socioedemographic and racial or ethnic group predicts pregnancy behavior.
The mediated
effects model holds that (a) these demographic factors are
associated with certain
cognitive and affective states, and that (b) it is these cognitive and
affective states
that best account for health behavior.
This thesis maintains that the mediated effects model is the more accurate
of the two. To test this assertion, certain factors need to be
identified, factors shown to be associated both with health behavior and with
demographic factors predictive of health behavior. These factors are:
(a) health locus of
control, and particularly fetal health locus of control (i.e., the extent to
which a
woman feels personal responsibility or control over the outcome of her
pregnancy); (b)
perceived social support from family and friends (i.e., the extent to
which one feels that
significant others are available for advice, comfort, and/or physical or
material
support); and (c) propositional knowledge about health, particularly
health behaviors
likely to affect pregnancy outcomes.
This mediated effects model proposed for testing is depicted in Figure 1.
As Figure 1 shows,
fetal health locus of control is conceptualized as the principal set of
beliefs affecting pregnancy health behavior. Fetal health locus of
control
is in turn associated with many cognitive and affective factors. Of
these, it is expected that perceived social support and propositional
health knowledge are the factors most likely to be correlated with fetal
health locus of control. Additionally, several demographic factors
such as
race, income, and educational level are likely to be associated with these
cognitive and affective states.
There are many features of the proposed mediated effects model that should
be tested. The core relationship being proposed in the model is that of
perceived
social support and propositional health knowledge with fetal health
locus of control. If
the mediated effects model is viable, then these cognitive and
affective factors should
better account for variance in fetal health locus of control than
should the demographic
variables of age, race, and socioeconomic status. This study tests
this assumption. The
following sections establish the foundation for asserting that fetal
health locus of
control is associated with both health behavior and with demographic
factors, and that
perceived social support and propositional knowledge should be
associated with these
demographic factors and fetal health locus of control.

*In this study, the health behavior of interest is seeking appropriate
prenatal care. "Appropriate care" is outlined by the Kessner Index: A
measure of timing and quantity of care--at least nine prenatal
check-ups
with the first visit beginning in the first trimester of pregnancy.
Figure 1. Mediated effects model illustrating multiple influences on
health behavior. Fetal Health Locus of Control
The concept of fetal health locus of control is adapted from Wallston and
Wallston's (1978) Multidimensional Health Locus of Control (MHLC).
Locus
of control is a psychological construct measuring the extent to which
individuals attribute events that happen in their lives as being the
result
of their own actions or outside forces. The theory underlying the locus
of control construct asserts that a reinforcement, reward, or
punishment of
a particular behavior will not necessarily be instructive unless one sees
a causal relationship between his or her actions and the
reinforcement,
reward or punishment (Rotter, 1966).
Wallston, Wallston, Kaplan, and Maides (1976) developed an instrument to
assess the locus of control construct in a health decision-making
setting.
The instrument includes Rotter's original two components, internal
(individuals generally hold themselves responsible for events that happen
in their lives) and external (individuals generally hold powerful
others,
fate, luck, or chance as being responsible for life's events), but the
questions were reworded to address the health context. Because of the
specialized nature of medicine, many people often seek professionals
("powerful others") for advice and consultation regarding their health.
Therefore, those individuals who continue to seek help regularly from
health professionals may score relatively high on the external dimension.
This type of external orientation is desirable in some matters of
health.
Consequently, Wallston and Wallston (1978) developed the
Multidimensional
Health Locus of Control (MHLC) which included three dimensions:
Internal,
Powerful Others (health care professionals) and Chance (fate or luck).
Chance and Powerful Others both are measures of tendencies toward
external
orientation, but scoring highly on the Chance component would better
predict noncompliant behavior than would scoring highly on the Powerful
Others dimension.
Repeated testing of the MHLC scale demonstrates its efficacy in predicting
health seeking behavior (for a review, see Coelho, 1985; Cooper & Fraboni,
1990; Larde & Clopton, 1983; Marshall, Collins & Crooks, 1990; Stanley,
Hyman & Sharp, 1984). Those who score highly in the Internal domain
have
the tendency to take responsibility for their health and to believe
that
their behavior directly affects their health status. They are more
open to
appeals on behavior modification and health outcome. Conversely, those
who score highly on the Chance scale may not seek health care as often
as
others, and may maintain unhealthful behavior because they do not
believe
it can positively or negatively affect their health condition. Those
with
a strong Powerful Others orientation may rely on doctors (or family
and
friends) for health advice (Amaro et al., 1987; Grady, Kegeles, Lund,
Wolk
& Farber, 1983; Noland, Riggs & Hall, 1985; Wallston, Smith, King,
Forsberg, Wallston & Nagy, 1983; Wallston & Wallston, 1978). Further,
studies have shown that there may be cultural differences in control
orientations. In a study by Weitzel and Waller (1990), African-Americans
scored higher on the chance component of health locus of control than
did
whites, particularly when education level was lower. Although the
study
employed a relatively small sample and the disparity in income between
the
African Americans and whites sampled was large, the results suggest
that
those with lower education levels, and African Americans in
particular, are
less likely to seek care for illness.
Because this study is concerned with how women perceive their behavior as
affecting another human being--the developing fetus--a fetal health
locus
of control scale (FHLC) was selected as an appropriate instrument for
assessing the locus of control orientation of young women who one day
will
be pregnant (Labs & Wurtele, 1986). This instrument measures the same
three dimensions of the MHLC, but the questions are designed to address
women's perceptions of their actions in relation to their future unborn
chi
ld. For example, one item in the Internal subscale reads, "My unborn
child's health can be seriously affected by my dietary intake during
pregnancy"; one item in the Chance subscale reads, "No matter what I do
during pregnancy the laws of nature determine whether or not my child
will
be normal"; and an item in the Powerful Others subscale reads, "My
baby
will be born healthy only if I do everything my doctor tells me to do
during
pregnancy" (response choices range from "strongly agree" to "strongly
disagree").
The FHLC scale has proven useful for measuring maternal health beliefs,
but it has not been tested extensively. Therefore, it will be
conceptually
useful to examine both FHLC and MHLC in order to illuminate health beliefs
more fully.
Factors that Predict Health Locus of Control
The fundamental questions addressed by this study is why are
African-American women less likely to seek prenatal care than women
from
other ethnic groups, and how can mass media messages encourage healthy
pregnancy behavior ? Clearly this connection is not genetically
determined. Many researchers suggest that people develop beliefs and
subsequent behavior patterns within their distinct social networks, and
these networks operate within specific cultures (Jaco, 1979).
Therefore,
in addition to learning about individuals' attributional control
tendencies, we also need to identify culturally encouraged assumptions
about health care. Culture may be defined in many ways, as an
economically
measured phenomenon or as a more abstractly delineated state. For the
purpose of this study, culture refers to the values, beliefs,
knowledge,
and behavioral customs shared by a particular group of individuals.
Often
these groups are bound by racial or ethnic ties. A cultural
perspective of
attributions of control offers further understanding of individuals'
health behavior (Pennebaker, 1982). Prescribing a conceptual model that
examines the influence of culture (race, ethnicity) on a health
beliefs
construct has important implications for health communication
researchers.
Studies continue to show that one's health beliefs may be the most helpful
unit of analysis for predicting health behavior. There is evidence that
in some cases health beliefs are better predictors of health service
utilization and health outcomes than demographic factors (TinsleyE&
Holtgrave, 1989). For example, a report from the Census Bureau shows that
Asians' and Pacific Islanders' poverty rate is higher than whites, yet
their infant mortality rate is significantly lower than the white infant
mortality rate (Centers for Disease Control, as reported by Eberstadt,
Wall
Street Journal, January 20, 1992). This suggests that culture and
subsequent health
beliefs supersede demographic factors in terms of health outcomes.
However, there are no
particular methods for assessing one's cultural background; rather,
the investigator is
attempting to discover what specific elements of culture influence
the development of
health beliefs and behaviors. This thesis asserts that one's
perceived social support
network, propositional health knowledge gleaned from mass media and
social networks, and s
ociodemographic variables of race, and income will best reveal the
influence of culture on
health locus of control beliefs. There is much research that supports the
notion that
these variables will explicate health beliefs in a cultural context.
Social support. One way culture can be transmitted is through one's social
support
system. Cultural beliefs, and subsequent health beliefs are
transmitted through one's
social contacts with family and friends. Social support may
influence health locus of
control in several ways, such as
(a) extensiveness (i.e., number of people in one's network; (b) quality
(the extent to which one feels socially supported; (c) type (i.e.,
emotional, physical, informational, material, social participation).
Individuals' feelings of social support are likely to be associated with
health beliefs for several reasons. First, individuals are often
reliant
on friends or family members' opinions when making personal decisions
about
health. Second, individuals who feel supported usually experience high
self-esteem (Rotter, 1966; ). High self esteem is related to having
an
internal locus of control.
Third, there is increasing evidence that a positive social network has an
ameliorating effect on health behavior. For example, studies have
shown
that African-American women who have strong social support systems are
more
likely to seek prenatal care, even while facing concrete obstacles such as
lack of insurance, no transportation to clinics, or no funds for
babysitters (St. John & Winston, 1989; Lia-Hoagberg et al., 1990).
Further, a study by the Centers for Disease Control (CDC, 1990) found that
unmarried mothers who are college graduates have a higher infant
mortality
rate than do married mothers who have less than a grade school
education.
Although based on only an eight-state sample in a pilot study, this
evidence clearly suggests that spousal support may be more important than
education in terms of pregnancy outcome. Thus, this study will expect
that
the association between demographic factors and fetal health locus of
control will be mediated by the nature and extensiveness of individuals'
perceived social support.
Propositional health knowledge. A second mechanism through which culture is
transmitted
is through the encouragement or discouragement of the seeking of
health knowledge and
through the transmission of folklore about health. Thus, there should
be cultural
differences on measures of propositional health knowledge.
Knowledge of appropriate health behavior is related to education, race,
and health beliefs, and it may follow that it is similarly related to
locus
of control and subsequent behavior. For example, knowledge that smoking
is related to premature birth is significantly different between
blacks and
whites, and blacks have a higher rate of low birthweight babies (Klesges,
et al., 1988).
Propositional knowledge may be an important predictor of health behavior.
Intuitively, we can posit that if a woman is unaware that prenatal care
should begin during her first trimester of pregnancy, and no one has
told
her otherwise, it is unlikely that she will monitor her pregnancy
closely.
Similarly, individuals who are unaware of the consequences of a particular
behavior may continue to engage in that behavior. For example,
African-Americans have a higher rate of heart disease and infant mortality
than do whites in the United States (National Center for Health
Statistics,
1987; OMH, 1989). In a study about smoking, 90 percent of whites and only
69 percent of blacks were aware that heart disease was related to smoking,
and 76 percent of whites and only 64 percent of blacks identified
premature births as being related to smoking (Klesges, et al., 1988).
These statistics suggest that propositional knowledge is another
important
contributor to health beliefs and behavior.
In a study of special education adolescents, Noland, Riggs, and Hall
(1985) found a significant association between propositional health
knowledge and health locus of control. Using the Children's Health Locus
of Control Scale (Parcel & Meyer, 1978), the researchers found that
Internal and Powerful Others subscales best predicted adolescents' health
knowledge. Belief that health is chiefly a function of chance was
negatively correlated to health knowledge, whereas high internality and the
belief that health is chiefly a function of Powerful Others were
positively related to health knowledge. These results suggest that those
who tend to take more responsibility for their health (internals) are
more
likely to attend to relevant health information. Similarly, those who
tend
to believe others (e.g., a parent, teacher, and/or doctor) are responsible
for their health are more likely to attend to information from
professionals, because they generally do not trust their own intuitions
regarding appropriate health behavior. Conversely, those who have a
tendency toward the "chance" orientation are not likely to assimilate
health information. They generally do not believe that changing their
behavior will make a difference in their lives.
Socioeconomic status: Race, income, education. There is a third way in which
the
influence of culture on health locus of control might be assessed.
Perhaps gross measures
of race and income level of teenagers' guardians, for example, may best account
for
variance in health locus of control and fetal health locus of control
among adolescents.
If this is the case, it will not be because race causes a certain
belief orientation, but
rather because there may be many ways that culture shapes health
locus of control and
fetal health locus of control and perhaps these sociodemographic
variables will best
account for this variance. For example, African-Americans as a group
may perceive they
face complicated and uncontrollable societal obstacles such as
racial prejudice that may
contribute to their development of particular control orientations.
Individuals' distinctive ethnic and racial cultures influence their
behavior and compel them to respond to different situations in a
particular
way (Wood, 1979). Because many studies have demonstrated cultural
differences in how people respond to illness (Pennebaker, 1982), it is
likely that culture affects health beliefs in segregated racial and
ethnic
groups. Few social scientists or health communication scholars,
however,
have focused on African Americans' and other minorities' health
beliefs and
corresponding behavioral patterns; most studies look at race and ethnicity
in relation to outcomes, such as use of services (K. Farraro, personal
communication, July 22, 1990). But much can be gleaned from extant
studies
on health beliefs as they exist in certain cultures.
Studying individuals' health beliefs and specifically measures of health
locus of control may provide the most useful conceptual framework for
understanding health outcomes, because it reflects the situational,
psychological, and physiological components of health behavior. Several
recent studies provide evidence for the notion that race and ethnicity
are
important predictors of the MHLC construct: African-Americans score
higher
on the Chance scale and lower on the Internal scale than do whites (Amaro,
Beckman, & Mays, 1987; Weitzel & Waller, 1990). These studies, however,
employed samples from lower socioeconomic groups. It is difficult,
therefore, to generalize these results to a broader income spectrum.
Motivation within different racial groupings also is related to HLC. For
example, those with high Chance health locus of control may not be
motivated to seek care or change unhealthful behavior except in an
emergency. In a study by Young et al. (1989), differences between
African-Americans and whites were examined regarding reasons for delaying
prenatal care. In the category "Utilization of Prenatal Care," more
than
twice as many blacks than whites reported motivation problems with
setting
and maintaining appointments as a major obstacle to seeking prenatal
care.
Of course, several other factors such as discomfort with clinical setting,
perceived poor treatment by physicians, lack of transportation, no funding
for insurance or babysitting, no family support system, could affect this
score, as well.
Summary of Culture and Health Beliefs
There is little doubt that culture is associated with the development of
health beliefs, such as health locus of control. But as this review
of
culture and health behavior has shown, it is difficult to assess a
culture's influence on health beliefs. This study posits that the
influence of culture on health locus of control will be observed in
associations of perceived social support, propositional health knowledge,
and demographic variables with health locus of control measures.
Research Questions and Hypothesis to be Tested
A review of the literature on health locus of control and its relationship
with the sociodemographic factors of race and income level, and with the
cognitive and affective factors of propositional health knowledge and
social support, demonstrates the efficacy of further study of the
mediated
effects model. Therefore, this study sought to answer the following
research questions:
RQ 1. To what extent is race/ethnicity related to high school aged
women's feelings of control over the outcome of pregnancy?
RQ 2. To what sources do female teens turn for information about health?
The study also tested one hypothesis:
H1. Cognitive and affective factors of health knowledge and perceived
social support will be associated with high school aged females'
feelings
of control over their own health or that of an unborn fetus, and these
associations will remain strong after controlling for the group
variables
of race and income.
Method
The study was designed to investigate infant mortality by assessing
sociodemographic, cognitive and affective variables that may predict young
women's locus of control orientations guiding their behavior during
pregnancy.
Study Design and Population
A cross-sectional survey design was employed. The sample consisted of
female students from four inner-city public high schools in
Indianapolis,
located in Marion County, Indiana. At the time of the study, Marion
County
had one of the highest black infant mortality rates in the country (OMH
1989; ISBH Report, 1989, 1993). This sample was selected for two
reasons:
(a) all four schools contain a relatively large minority population;
and
(b) students from these schools represent a broad socioeconomic range
from
poverty level to upper middle class. On the assumption that factors
other
than sociodemographics will be linked to African-American and white
women's
health beliefs important during pregnancy, it was necessary to include a
balance of both African-American and white subjects from different
socioeconomic classes.
To achieve a representative sample with a broad range of academic
abilities, eligible subjects were those women enrolled in required courses
(such as history, health, or physical education) within each high
school in
grades nine through twelve. Consent from both student participants and
their parents was obtained prior to conducting the survey.
Survey Response Rate and Frequency Distributions for Race and Income Groups
A total of 215 parental consent forms were distributed to female students
at the four high schools in the summer and fall of 1992. Of these,
102
high school women between the ages 14 and 19 returned signed parental
consent forms and participated in the survey study, for a response rate
of
47 percent. The average age for the sample was 16. Four of the
respondents were not included in the analyses because they had failed to
complete questions pertaining to the dependent measures plus one or
more
independent measures (N = 98). [1]
Participants included 47 whites and 51 African-Americans. Although this
ratio does not reflect true population parameters, it was necessary in
this
study to over-sample African-Americans to examine factors that affect
black white-differences in health beliefs.
The variable "income level" was coded in the following way: 0 refers to
those families with incomes that fall below the government guidelines
for
determining poverty based on annual income and number of family member
dependents (United States Department of Commerce, 1990), ranging from
$5,000 to $19,000 annually (poor); 1 refers to those families whose
incomes
range from approximately $10,000 to $22,000 annually (low income); 2
refers to those families whose incomes range from approximately $18,000
to
$45,000 (middle class); 3 refers to those families whose income level
range
from $45,000 to greater than $70,000 annually (upper-middle class). These
income categories were based on the poverty guidelines, with each
subsequent level spanning an income range of one-third above the previous
level, based on the number of family members. For example, a family
of
three with one child under 18 can make up to $10,520 annually to be
considered below the poverty level, or Level 0 in this study. For Level
One, the same size family could make from $10,521 to $13,992.
Similarly, a
family of eight (six children under age 18) can make up to $21,505
annually
to remain under the poverty level guidelines (Level 0). Family income
level reflected a normal distribution for both blacks and whites--no
significant differences existed between races on income level in this
sample (mean scores for income level are 1.34 for blacks, sd 1.17; and
1.13
for whites, sd .1.06). Academic achievement (self-reported grade
point average based on a
4.0 scale) also shows no significant difference between GPA of
whites and
African-Americans (mean score for African-Americans was 2.40, sd
.67; mean score for
whites was 2.42, sd .65).
General Procedures and Materials
The set of surveys administered included five instruments designed to test
the relationships of demographic, cognitive, and affective variables with
subjects' enduring health beliefs. Specifically, three instruments
were
selected or developed to obtain independent measures respectively of
(a) subjects' sociodemographic groupings (including mass media channel
selection for health informtion); (b) subjects' propositional knowledge
about general health topics including healthful behavior and pregnancy
health behavior; and (c) subjects' perceived social support.
Additionally,
two instruments were combined to assess the dependent measures of
subjects'
health beliefs: (a) multidimensional health locus of control (MHLC) and
(b) fetal health locus of control (FHLC). These two scales were
integrated
to avoid drawing students' and school administrators' attention to the
project's focus on pregnancy health beliefs.
Independent Measures
Sociodemographic characteristics survey. This instrument was developed to
assess
respondents on a number of different characteristics, including health
information sources
used, race, academic achievement, and family income level. To determine health
information sources used, respondents were asked to select from a list and
rank order all
the sources (newspapers, television, radio, magazines, textbooks,
mal friend, female
friend, parent, school teacher or counselor, religious leader, health
care professional,
and "other") they turn to in order (a) to seek information about
health issues, or (b) to
obtain health information for a sick friend.
Race of respondent was determined by asking them to identify the race
category for each parent. For the purpose of this study, a listing of
"African-American" for one parent (even if the other parent was of a
different race) placed the respondent in the "black" racial category.
This
was done for 2 of 98 subjects.
Academic achievement was assessed by asking respondents to list the
overall grade point average (4.0 scale) they had accrued in high school up
to the time of the survey. Although considered as an individual
difference
variable in study analyses, the academic achievement assessment was
included in this instrument because it fit appropriately with other
personal information requested in the survey.
To appraise the family income level of respondents, respondents were asked
to describe the jobs held by each of their parents or guardians, indicate
whether each job was full or part time, and repeat the same
information if
second jobs were held by parents or guardians. Next, respondents were
asked to estimate their family income level.
For the purpose of the study, the researcher checked the respondents' job
descriptions with the job earnings listings for the year 1988 in the
United
States Bureau of Labor and Statistics Report for Median Incomes of
Wage Earners (1989),
and compared the median income listed in the report with those
selected by respondents,
taking into account all jobs described by respondents. Because the
complete reports are
only published for five-year periods, the report for the years 1983
to 1988 was the most
recent comprehensive summary available. Eighty-six percent of the
job descriptions and
annual family income levels reported by respondents matched within
ten percent above or
below what the labor statistics report listed as median income
levels for the jobs
respondents described. The ten percent range on the top and bottom was
allowed as a match
for respondents' answers because the government reports median incomes rather
than a
range of incomes for each job. Therefore, it is difficult to
calculate exact
correspondence between respondents and the labor statistics report. Given
that no
detailed information was available from respondents, such as wage
earners' length of time
employed at each job, or whether or not workers were union members,
the ten percent
latitude for agreement was deemed reasonable. Two coders were used to
determine family
income levels of the thirteen respondents whose income estimates for
the jobs they listed
did not fall within ten percent above or below what the labor
statistics report listed for
the corresponding jobs. The purpose of the coders was to determine if the
initial coder
had erred in interpreting the job descriptions provided by
respondents, to account for the
non-agreement between respondents' answers and the labor statistics report.
Inter-item
coder reliability for these cases was 93 percent exact agreement.
In these thirteen cases
where there was no income level agreement between the respondents and the labor
statistics report, respondents' answers were privileged. That is,
subjects' responses
were deemed correct.
Propositional health knowledge. Propositional health knowledge refers to
individuals'
knowledge about general health issues such as hygiene and other
preventive care topics
that they should know given their age and educational level. It is
an important concept;
people's health knowledge has shown to guide behavior.
To measure health knowledge, a portion of a 50-item multiple choice survey
designed to reflect the health topical areas typically studied at the high
school level was used (Noland, Riggs, & Hall, 1985). Questions cover such
topics as how venereal diseases are contracted, which foods contain the
greatest amount of protein, and what diseases are related to cigarette
smoking. The reading level of the scale is directed at the fourth to
fifth
grade, and the scale was tested on high school aged special education
students. Therefore, the instrument was appropriate for this study
sample.
For the purpose of this study, the general nutrition and health questions
allowed the researcher to study health knowledge important during
pregnancy. Additionally, three questions about a woman's health behavior
during pregnancy were added to assess knowledge of appropriate
pregnancy
health behavior. Although the new questions had not been tested
previously, the questions reflect what health experts list as crucial
knowledge about behavior for ensuring a healthy newborn baby. While the
inter-item reliability for this scale was deemed low but acceptable
(Cronbach's alpha = .56), it was not expected that a scale assessing
knowledge of several different health topic areas would generate high
reliabilities.
Perceived social support network inventory (PSNI). The social support measure
used was
the Perceived Support Network Inventory developed by Oritt, Paul,
and Behrman (1985). The
instrument was selected because it provides a multidimensional
assessment of individuals'
perceptions of the social support they receive. Oritt et al.'s
measure of perceived
social support allows the researcher to look at preconceptions and
attitudes people have
about individuals within their social network that shape the types
of interactions that
will occur during stressful times. This comprehensive scale
assessed respondents'
perceived social support network on several different levels, including
the extensiveness,
nature, and quality of a person's social support network.
The validity and reliability of this instrument have been well-tested:
test-retest reliability total scores and subscale scores range from
.72 to
.88; internal consistency for the PSNI is .77 (using Cronbach's
alpha);
convergent validity ranges from -.25 to .20; and discriminant validity
estimates ranged from -.11 to .19. (Note: In general, convergent
validity
should show high correlations, but for the purpose of this test strong
inverse associations are desired.) Care was taken to maintain the
clarity
and meaning of each subscale and instructions after editing the
instrument's wording for a high school population.
Dependent Variable Measures
Multidimensional health locus of control (MHLC). The MHLC (Wallston and
Wallston, 1978)
was administered as an additional measure of health locus of
control. Individuals who
score highly on the internal subscale have the tendency to feel
personal responsibility
for events that happen in their lives. Those who score highly on
the external subscales
have the tendency to believe that other forces such as luck, chance,
or powerful others
are ultimately responsible for events that happen to them in their
lives. Health status
positively correlates with internality.
An example of an Internal subscale question is "If I take good care of
myself, I can keep from getting sick"; a Chance subscale question is
"My
good health is largely a matter of good fortune"; and a Powerful
Others
subscale question is "When it comes to my health, I can only do what my
doctor tells me to do." (Cronbach's alpha for this sample was .58 on
the
internality subscale, .67 on the chance-externality subscale, and .63
on
the powerful others-externality subscale. )
Fetal health locus of control (FHLC). The primary dependent measure used in
this study
was the fetal health locus of control scale (Labs & Wurtele, 1986).
The 18-item
instrument is designed to assess the extent to which women perceive that
their actions
during pregnancy will affect the health of their future unborn baby.
FHLC is an important
construct to study, because few locus of control studies have examined control
orientation in terms of how one believes his or her actions affect another
human being.
Some researchers have recognized the importance of looking at
women's health beliefs
because women typically are responsible for managing the care of their
pregnancies, and
for managing the care of their children. The Labs and Wurtele (1986)
scale sought to
measure the control orientation of women who are pregnant or of
child-bearing age. The
researchers confirmed a relationship between a woman's tendency
toward internal
orientation and the likelihood that she would seek prenatal care, an
important
relationship for this study, as well.
Like Wallston & Wallston's (1978) MHLC instrument, it consists of three
subscales: internal, chance, and powerful others. Scoring highly on
the
internal subscale expresses an individual's general belief that she is
personally responsible for having a healthy baby. An example of an
internal
subscale question is "My unborn child's health can be seriously affected
by my dietary intake during pregnancy." Scoring highly on the chance
subscale expresses an individual's general belief that there is little
she
can do to change the outcome of her pregnancy; fate, luck or chance
plays a
major factor. An example of a chance subscale question is "Having a
miscarriage means to me that my baby was not destined to live." Scoring
highly on the powerful others subscale expresses an individual's
general
belief that the health of her unborn child lies in the hands of health
professionals who manage her care. An example is "Only qualified health
professionals can tell me what I should and should not do when I am
pregnant." As with the Labs and Wurtele study, subjects were instructed to
answer the questions as if they were planning a pregnancy in the near
future.
For this sample, Cronbach's alpha was .63 on the internality subscale; .85
on the chance (externality) subscale; and .71 on the powerful others
(externality) subscale. Because the fetal health locus of control
instrument had not been tested extensively, the investigator calculated
correlation coefficients for the two dependent measures,
multidimensional
health locus of control (MHLC) and fetal health locus of control
(FHLC),
and for each of their subscales. The total scale score (means) of the
two
scales were significantly correlated (r = .56, p < .01), and
significant yet not
always strong associations existed between each of the subscale
scores: internality
subscale for FHLC and MHLC (r = .27, p < .01); powerful others
dimension of externality
subscale for FHLC and MHLC (r = .51, p < .01); and fate, luck or
chance dimension of
externality subscale for FHLC and MHLC (r. = .48, p. < .01). A high
correlation between
the scales was not expected; the MHLC assesses one's feelings of
control over one's own
health, while the FHLC assesses a woman's feeling of control over
someone else's
health--the outcome of a pregnancy.
Procedures
The five surveys combined took respondents an average of 38 minutes to
complete. The survey was administered during regular class time (a
45-minute time limit) to allow as many students as possible to participate.
Students who participated in the study were assured of anonymity and
confidentiality. Response formats for the administered scales varied,
ranging from a five-point Likert-type scale, to a multiple-choice
selection
that reflects correct and incorrect answers, to open-ended questions
designed to assess individual or family characteristics. (See Table 1for
a
list of variables used in the study.)
Results
The first research question was answered through a series of correlational
analyses between race and different dimensions of multidimensional health
locus of control and fetal health locus of control.
Race and income level and multidimensional health locus of control. As
expected,
results did not support the sociodemographic model of health behavior
disputed in this
thesis. No significant relationships were found between race and the
total mean score of
the multidimensional health locus of control scale (r = .06, p =
.53, ns) or income level
and the total mean score of the multidimensional health locus of
control scale (r = -.05,
p = .63, ns). Similarly no significant relationships exist between
income level or race
and the subscales of the multidimensional health locus of control
instrument.
Race and income level with fetal health locus of control. Again, results did
not
support the sociodemographic model challenged by the investigator. No
significant
relationships were found between the two group variables and the total
mean scores of the
fetal health locus of control scale. The correlations were: race
and fetal health locus
of control (r = -.02, p = .82, ns); and income level and fetal
health locus of control (r
= -.15, p = .13, ns).
Only one significant association was found between a group variable and a
dimension of fetal health locus of control. A significant but modest
relationship exists between income level and fetal health locus of
control-powerful others (r = -.24, p < .05), indicating that the lower the
income
level, the stronger the orientation toward powerful others
(externality). No significant
relationships exist, however, between the group variable income
level and the chance
subscale of fetal health locus of control (r = .00, p = .98, ns),
between race and fetal
health locus of control-chance (r = -.09, p = .37, ns), between race
and fetal health
locus of control-powerful others (r = -.04, p = .70, ns), or race and
income level and
fetal health locus of control-internality (r = .16; r = -.02,
respectively; p > .05 for
both correlations, ns).
Female teens' health information sources. The study also answers the second
research
question regarding teen-aged females' key health information sources.
Respondents each
identified from one to six health sources they typically turn to for
information on health
issues. A majority (62 percent) reported they would turn to a parent for
health
information, 40 percent reported television, and 30 percent reported
newspapers or
magazines as one of their key health sources. A surprising 31 percent
turn to male
friends as major sources of health information.
When asked what sources they would seek out to get pertinent health
information for a sick friend, a majority of respondents (73.5 percent)
reported they would turn to doctors or nurses. Sixty-five percent also
would turn to a parent, 37 percent to female friends, 22 percent to a
teacher or school counselor, and 21 percent would turn to male friends as
additional sources of health advice. Mass media are less important
sources
when specific and urgent health information is needed: In this
hypothetical circumstance, only eight percent reported newspapers and
magazines, and 16 percent reported television as sources for health
advice.
Test of the Mediated Effects Model
Statistical analyses support this study's hypothesis (the
cognitive/affective model of health behavior): high school aged
females'
propositional health knowledge and perceptions of their social support
networks are significantly associated with feelings of control over
personal health and with feelings of control over the outcome of
pregnancy. Most pertinent to this study, propositional health knowledge
and perceived social support maintain strong associations with control
orientations for health and pregnancy outcomes even after controlling
for
the sociodemographic variables of income level and race. This finding
suggests that those who feel more knowledgeable about health or more
socially supported are more likely to believe that they themselves are r
esponsible for their own health and that of their future babies than
are
their counterparts. Further, these relationships remain stable after
controlling for the effects of race and income level.
General health knowledge and multidimensional health locus of control. As
hypothesized,
the results indicate a strong association (see Table 2) between
general health knowledge
and the overall scale mean scores of multidimensional health locus
of control (r = -.48, p
< .001). Similar findings occur with health knowledge and the two subscales of
externality: For chance, r = .41,
p < .001; and for powerful others, r = -.33, p < .001. This means that general
health
knowledge is associated with female teens' feelings that powerful
others such as family
members or doctors control their health, and it also is associated
with their feelings
that either fate, luck, or God controls their health.
Further, this relationship is not affected when the variance accounted for
by race and income is controlled (see Table 3). The first-order partial
correlation between health knowledge and total mean score of the
multidimensional health locus of control, controlling for race, is -.47
(the zero-order correlation is -.48). In addition, controlling for the
variance associated with income also does not affect the strong
association
between health knowledge and locus of control. Controlling for income
level, the first order partial correlation of the two variables is
-.48.
Whereas the zero-order correlation for health knowledge and
multidimensional health locus of control-chance is -.41, the
first-order
partial correlations for the two variables -.41, controlling for race;
and
-.41, controlling for income level. For the powerful others subscale,
the
zero-order correlation is -.33, and the partial correlations are -.33,
controlling for race; and -.33, controlling for income.
General health knowledge and fetal health locus of control. A similar
relationship
exists (see Table 4) between general health knowledge and fetal health
locus of control
total mean scores (r =
- .39, p < .001). These negative correlations show that individuals who score
lower on
the general health knowledge measure score higher on the externality
dimension of control
(they believe that their own health status or their unborn babies'
health is the result of
powerful others in their lives and/or fate, luck, or chance). Subsequently,
those who
have higher scores on the health knowledge assessment score higher
on internality,
represented by a lower score on the internality subscale (r =
.20, p < .05). Analogous associations were found between health knowledge and
the
subscales of powerful others and chance, both measures of externality (r
= -.33, p < .001;
r = -.24, p < .01, respectively). These significant associations are not
affected after
controlling for the effects of race and income (see Tables 5 and 6). Thus, the
partial
correlations reveal little variance among the hypothesized
associations after controlling
for the effects of race.
Although the direction of these relationships cannot be assessed with this
study design, one can posit that knowing what constitutes appropriate health
behavior is efficacious to feeling in control of personal health
matters.
Perceived social support and multidimensional health locus of control. There
were no
significant associations between perceived social support and the
total mean score of the
multidimensional health locus of control scale, or between perceived
social support and
the three subscales of multidimensional locus of control (see Table
2).
Perceived social support and fetal health locus of control. One significant
association
exists between the affective variable, perceived social support, and
fetal health locus of
control measures (see Table 4). The strong association between social support
and the
internality subscale (r = -.40,
p < .001) means that the higher the score on the perceived social support
scale, the lower the score on the internality subscale. A lower score
on
the internality subscale, however, indicates a more internal
orientation.
Further, after controlling for race and income, the association between
perceived social support and fetal health locus of control remains
strong
(see Tables 5 and 6). The first-order partial correlations are:
controlling for race, r = -.38, controlling for income level, r = -.40.
Discussion
The study shows that perceptions of social support and general health
knowledge are significantly associated with fetal health locus of
control.
The study also demonstrates that cognitive and affective variables are
more likely to be associated with feelings of personal efficacy toward
a
fetus than are the more commonly used demographic predictors such as
race
and income. Therefore, the investigation offers support for the
hypothesized indirect effects model of health beliefs. Specifically,
analyses support the indirect effects model in several ways: (a) no
significant relationships were found among the variables of race and fetal
health locus of control and only one significant relationship was
found
among the variables of income and health locus of control;
(b) strong associations were found between the cognitive and affective
variables and the dependent measures of fetal health locus of control
and
multidimensional health locus of control; and
(c) systematic variations exist in the strength of the associations among
the cognitive and affective predictors of fetal health locus of control.
Of these three categories of findings, the most powerful evidence for
the
model is found in the reports of the systematic variations in the
relationships among the independent and dependent measures. The discussion
that follows will elaborate on each of these findings that support the
indirect effects model and describe the implications for application.
Support for the Direct Effects Model
Race and income level. The fact that no significant association was found to
exist
between race and control orientation is interesting in itself. This
finding differs from
those of Amaro, Beckman, and Mays (1987) and Weitzel and Waller
(1990) that linked race
and control orientations. In these studies, African-Americans
scored higher on the chance
scale and lower on the internal scale than did whites. Both studies, however,
employed
samples from lower socioeconomic groups, and therefore may have
confounded race with low
income. In the current study, the sample was balanced on
sociodemographic variables of
race, income, and academic achievement (self-reported grade point
average), in an attempt
to avoid such confounding. Further, because only one significant
association was found to
exist between the group factors and fetal health locus of control, it appears
that race
and income have no direct effects on female teens' control
orientations in this sample.
General health knowledge. Statistical analyses offer support for the cognitive
link in
the indirect effects model of health behavior. These findings
suggest that general health
knowledge and feelings of control over one's own health maintain strong
associations,
even after controlling for the effects of the sociodemographic
variables of race and
income level. In summary, health knowledge is important in two ways.
First, this study
has shown that general health knowledge is significantly associated
with measures of
health locus of control and fetal health locus of control, even after
controlling for the
effects of race and income level. Second, possessing accurate
health knowledge may
potentially lead teens to more healthful behavior.
Social support. The fact that the study found social support to be
significantly
associated with fetal health locus of control and not with
multidimensional locus of
control suggests that perceived social support may not affect
individuals' control
orientations about their own health, but it may have an effect on how
women feel their
actions affect the health of other beings, their future children.
This finding suggests
that the more socially supported people feel, the more personally
efficacious they feel
about pregnancy outcomes.
Systematic variations: General health knowledge, perceived social support, and
measures
of fetal health locus of control as a function of race and income
level. By looking at
systematic variations in these associations the roles of race and
income can be examined
further. (See tables 7 and 8 for the listings of systematic
variations by race and
income.) Interestingly, the strength of the associations among health
knowledge, social
support, and fetal health locus of control vary systematically and
significantly as a
function of race and income. This is the case both for the
association between health
knowledge and fetal health locus of control and between perceived
social support and fetal
health locus of control. By dividing the sample into units by race and income,
the
investigator can explore further the strength of the hypothesized
associations in relation
to race and income. Further analyses indicate that the relationships between
health
knowledge and fetal health locus of control and between perceived
social support and fetal
health locus of control do vary systematically as a function of race and
income, lending
support to the idea that race and income have indirect rather than
direct effects on
health beliefs.
Specifically, the associations between health knowledge and fetal health
locus of control differ for African-Americans and whites. For the
entire
sample, general health knowledge is significantly associated with
fetal
health locus of control on each dimension: With the total scale, r =
-.39,
p < .001; with internality, r = -.20, p < .05; with powerful others,
r = -.33, p < .001;
with chance, r = -.24, p < .01 (see Table 4). The strength of the
associations differs,
however, for whites and African-Americans (see Table 7). For
example, if the sample is
divided on race alone, the association between health knowledge and
fetal health locus of
control-internality is not significant for either group. Rather,
the strongest
associations exist between health knowledge and the total scale score for
low income
whites (those whites who fall in the lower two levels of income within
the sample [r =
-.53, p < .01]) and for high income blacks (those African-Americans
who fall into the
upper two income levels within the sample [r = -.50, p < .01]).
Interestingly, the
association is not significant for high income whites (r = -.24, p =
.29), or for low
income blacks (r = -.18, p = .41). Other systematic variations in
associations between
health knowledge and fetal health locus of control occur on the
chance subscale for blacks
and whites. It was significant for low income whites (r = -.47, p < .01) but
not for
high income whites (r = -.23, p = .30, ns); significant for high
income blacks (r = -.45,
p < .05) but not for low income blacks (r = .25, p =.24, ns). One
reason for these
disparate results, such as the fact that health knowledge and fetal
health locus of
control are significantly associated for low income whites but not for
low income
African-Americans, may be that for low income whites, greater health
knowledge is indeed
empowering. But for low income blacks, there may be many other
obstacles (racial
prejudice, less support from the white majority, etc.) that block the
effects of health
knowledge on beliefs of personal efficacy. Additionally, poverty
may have a more powerful
impact on African-Americans, since they as a minority in the United States
comprise the
majority of low income families (OMH, 1989). There may be other
more significant factors
related to feelings of personal efficacy among poor
African-Americans, such as perceived
social support.
For the sample as a whole the association between perceived social support
and fetal health locus of control internality is significant (r = -.40, p <
.001). The association is greater, however, for African-Americans
than for whites (see
Table 8). Examining the association by race shows that perceived
social support is an
important factor in health beliefs for African-Americans in both low
and high income
groups. This is not the case with the white female teens; the
association was significant
only for whites as a group and for low income whites. Specifically, for
African-Americans only, the correlation coefficient is -.45 (p <
.01); for whites only,
the correlation coefficient is
.29 (p < .05). This is an important finding because it suggests that a
perceived strong
social support network is a key correlate of internality for
African-Americans in
particular. Further, the two factors are strongly associated both for
African-Americans
and for whites in the lower two income levels: For
African-Americans, r = -.44 (p < .05),
and for whites, r = -.43 (p < .05). In the upper two income levels, however,
the
associations are dissimilar: For African-American females in the upper
two income levels,
the correlation coefficient for perceived social support and fetal health locus
of
control-internality is -.43 (p < .05, sig.), but for white females it is
only -.15 (p =
.51, ns). (Note that a low score on a scale indicates a tendency
toward internality.)
Several significant associations exist between social support and fetal
health locus of control measures for African-Americans (see Table 8).
Among all African-Americans sampled, the significant associations are:
social support and fetal health locus of control total scale, r = -.36,
p <
.01; and social support and fetal health locus of control
internality, r = -.45, p < .01.
Among African-Americans in the upper two income levels sampled, the significant
associations are: Social support and fetal health locus of control total,
r = -.40, p <
.05; and social support and fetal health locus of control
internality, r = -.43, p < .05.
Finally, among African-Americans in the lower two income levels sampled, there
is one
significant association: social support and fetal health locus of
control internality, r
= -.44, p < .05. The fact that only two significant correlations
exist between social
support and fetal health locus of control measures for the white
population sampled (on
the internality subscale for all whites sampled and for whites in
the lower two income lev
els), suggests that social support is a more significant factor
contributing to fetal
health locus of control orientations among African-American teenaged
girls than for white
teenaged girls. (Again, note that a low score on a scale indicates
a tendency toward
internality.)
This pattern of findings strengthens the claim that factors such as
perceived social support better account for variance in locus of control
orientations among African-Americans and whites than do
sociodemographic
variables such as income level. It also supports the claim that the
effects of race and income are indirect rather than direct. One reason
this phenomenon may occur is because there are few approbations
inherent in
American society that contribute positively to African-Americans'
perceptions of social support. Even the most prosperous African-Americans
face multiple barriers such as racism, negative stereotyping, and
distrust,
that may subvert feelings of being well supported.

Clearly, African-Americans' perception of the strength of their social
support system is a key factor in their lives. Teenaged black women
who
endure real societal barriers and retain the perception that they are
not
well-supported by family, friends, and others in their lives
apparently
also believe that their actions during pregnancy will not make much
difference on the outcome of pregnancy. Those who believe they can count
on individuals for emotional and material support are more likely to
feel
internally responsible for their unborn children.
Implications of the Mediated Effects Model on Public Health Campaigns
This study illuminates our understanding of why some women do not and some
women do seek prenatal care, regardless of socioeconomic status. A focus
on individual differences also has important implications for public
health
campaigns. First, the model offers new directions for identifying
relevant target publics. Second, the model provides insight for message
content considerations. Lastly, study results illustrate the
importance of
advocacy media in health communication,
Support group members as target audiences for pregnancy behavior campaigns. It
would be
interesting to examine the types of pregnancy health messages that
would be generated from
members of the social support network, such as male peers (who female subjects
turned to
most for support), parents, counselors, and teachers, if they were
consulted by female
teens, and to learn about what it takes to bolster feelings of social
support. For
example, messages similar to the "Friends don't let friends drive drunk"
campaign may be
beneficial for encouraging support of pregnant young women.
Targeting non-pregnant
members and potential members of a pregnant woman's social network may
indirectly affect
health behavior. Although "Good friends help a pregnant friend
through pregnancy" may
seem overly simplistic, it is a relevant and appropriate approach
given the study
findings.
Additionally, males serve an important role in high school aged females'
lives. High school women frequently turn to males both for social
support
and for health information: Thirty-seven percent of respondents, when
asked
to identify up to seven key members of their social support network,
listed a male first. The findings suggest that public health campaigns
directed at females only may be missing an influential audience.
Because
the study found that being informed about health is connected to
having an
internal control orientation, informing young males about what factors
contribute to having healthy babies may benefit teenaged women.
Therefore,
messages should be designed to encourage males--African-Americans in
particular--to be supportive and helpful to pregnant friends.
Additionally, messages also should provide accurate and pertinent
information to males about appropriate pregnancy behavior for women.
The role of mass media and health. Respondents frequently attend to health
information
they glean from television and magazines. Because the study results
indicate a strong
association between general health knowledge and control orientations
and social support
and control orientations, mass media should be used to encourage
supportive behavior by
illustrating, describing, and informing audiences of desired
behavior, in direct and
indirect ways. Mass media messages should highlight the actions of
supporters as well as
the healthful conduct of pregnant women in various ways to
illustrate a lifestyle of
healthy and supportive behavior. While current trends of increasing
access to services is
important to continue, the study demonstrates that access is not the principal
obstacle
to health behavior.
For example, magazines with large female teen audiences currently do
little to encourage healthy pregnancy behavior (Fellure, 1993). In a
preliminary content analysis, Fellure found that top magazines read by
teenagers offered little specific information about pregnancy health
behavior. There was an abundance of information about how to avoid
becoming pregnant, but none pertinent to health behavior during pregnancy.
Further, although magazines targeted to African-Americans contained
articles about black families, the father's role in particular, the
articles focused primarily on celebrating and encouraging family life.
While a spotlight on parental involvement certainly is a valid approach
to
supporting family values, it is surprising that the African-American
and
mainstream magazines reviewed gave few details about specific behavior
that
could lead to having healthy babies (e.g., when doctor visits should
begin, how much weight gain to expect, how nutritional habits affect the
fetus). This may be true, of course, because editors do not want to
appear
as though they are encouraging pregnancy among teens. Nevertheless,
editors could frame pregnancy information so that they are encouraging
future responsible pregnancy behavior.
Additionally, editors of the teen magazines reviewed by Fellure may have
neglected or failed to provide more specific pregnancy health
information
because the community as a whole wishes to ignore the problem of teen
pregnancy among white and black teens. Therefore, while many popular
magazines seem to do a good job of modeling socially supportive behavior,
clearly there is a need for gatekeepers to provide crucial health
information regularly to the audiences they serve.
Directions for Future Research
This study has interesting implications. First, because female teens seek
health information and support from a variety of sources, including males,
it would be helpful to explore males' health knowledge about pregnancy.
Their advice and information may influence women's decisions about
pregnancy. For example, are women worried about weight gain and
subsequently diet while pregnant because of males' perceptions of how much
weight a woman should gain during pregnancy? And are males from
certain
ethnic groups more inclined than others to be concerned about too much
weight gain during pregnancy? Additionally, because respondents often
seek
health information from television and other mass media sources, content
analyses, such as the study described earlier (Fellure, 1993; see also
Landis, Freimuth, & Cameron, 1993), should be conducted to determine the
types of pregnancy health messages that both males and females
receive
from mass media channels.
The relationship of social support and health behavior should be explored
further, particularly among African-Americans. The strong association
between social support and fetal health locus of control orientations
for
all African-American respondents regardless of socioeconomic status,
and
the divergent finding that the association was significantly strong
only
for whites from lower income brackets, warrants further examination.
Additionally, communication scholars report extensive research that
demonstrates a significant relationship between social support and actual
physical and mental well-being, and recovery from illness (Burleson,
1990;
Kessler & Essex, 1982; Sarason, Levine, Basham, & Sarason, 1983;
Sarason,
Shearin, Pierce, & Sarason, 1987; Sullivan & Reardon, 1986).
Therefore, research should be conducted to test the associations between
social support and health beliefs and health behavior that may exist
for
populations other than high school women. For example, physicians are
unable to explain phenomena such as why socioeconomic status is linked
to
health status (Pappas, Queen, Hadden, & Fisher, 1993). Pappas et al.
were
unable to explain findings that showed even though Medicaid and other
health programs for the poor increased over a 26-year period, the gap
betwe
en social classes in death rates also increased. Although death rates
decreased overall in this period, the reduction was much more dramatic
for
college-educated males: The rate fell from 9 deaths per 1,000 in
1966, to
7.6 per 1,000 in 1986, among white males with less than a high school
education; and from 5.7 deaths to 2.8 deaths per 1,000 for white
college-educated males. The authors found the same dissimilarity exists
for low versus high income populations. Research examining the
relationship between social support, socioeconomic status, and health locus
of control measures in other population samples may illuminate problems
such as the disparity in death rates by socioeconomic status.
Conclusion
The question motivating this study is: Why are African American women
less likely to seek prenatal care than women from other ethnic groups,
and
how can mass media help change this pattern? Public health
professionals,
however, often treat disparate health status as a product of race and
income level alone. Therefore, these officials respond to health
discrepancies by providing new services and informing the target audience
about the services. But extant studies demonstrate that this strategy
often is ineffective. For example, the sociodemographic effects model
fails to address enduring dispositional attitudes that guide health
behavior. Additionally, the model ignores cognitive and affective factors
that contribute to health beliefs.
This study supported the need for a mediated effects, or a comprehensive
model of health behavior, that will better inform health communicators
about possible deterrents to health behavior. The core relationships
this
study identified are those of propositional health knowledge and
perceived social support
with fetal health locus of control. The study results indicate that
these cognitive and
affective factors better account for variance in health beliefs than
race and income
level, though the strength of these associations varies with race and
income.
There are four primary advantages to viewing health status from a mediated
effects approach. First, the model explains anomalous findings that
demographics cannot explain, such as why African-American women are less
likely than whites to seek prenatal care regardless of income level.
Second, the model may be generalizable to health behavior other than
pregnancy behavior. Third, the model offers a mechanism for identifying
obstacles to healthful behavior, some of which could be addressed
with
public health campaigns. For example, it helps explain why roughly
half of
all pregnant African-American women do seek prenatal care in their first
trimester and why the other half does not. These women may differ in their
knowledge of
health and feelings of social support. Finally, the model supports
other health
communication researchers who have called for an integrated approach for
health campaigns,
one that incorporates both mass communication and interpersonal communication
strategies,
to reach targeted populations (Pettegrew & Logan, 1987; Reardon, 1988).
Developing comprehensive models of health behavior that describe
interrelations among culture and cognitive and affective factors will
contribute to health communication researchers' understanding of group
behavior. Public health professionals informed by such models may find
more effective and successful approaches for reaching high risk
populations. References
