Scales for measuring health belief model dimensions: a test of predictive value, internal consistency, and relationships among beliefs.

Critiques of research on the Health Belief Model have been directed at the need for: (1) applying the Model to behavior related to chronic illness; (2) multivariate testing of the major dimensions of the Model; (3) developing reliable scales; and (4) explicating the relationships among the beliefs. In an attempt to respond to these concerns, data are presented from a prospective study of mothers' adherence to a diet regimen prescribed for their obese children. The Model components were found, both singly and in combination, to be correlated with the study's measure of dietary compliance. Multiple regression analysis utilizing five belief indices accounted for a substantial portion of the variance in children's weight change. Questionnaire items employed in creating indices for each Model dimension are presented, together with discussion of the internal consistency of each index. Belief intercorrelations appear to demonstrate that distinct Model dimensions exist.

Sociobehavioral determinants of compliance with health and medical care recommendations.

Over the past two decades, hundreds of articles, editorials, and commentaries have been published describing the considerable disruptive effects on quality of care of individuals noncompliance with health and medical advice. While much research has been directed at determining factors responsible for poor compliance, past studies have tended to focus upon easily measured characteristics of the patients, regimen, or illness which, unfortunately, are usually neither predictive nor alterable. This paper systematically reviews the literature on patient acceptance of recommended health behaviors, attempting to find social-psychological and related variables which have proven to be consistent predictors of compliance. The review suggests that certain health beliefs (especailly personal estimates of vulnerability to, and seriousness of, the disease, and faith in the efficacy of care), health-related motivations, perceptions of psychological and other costs of the recommended action, various aspects of the doctor-patient relationship, and social influence are the most productive dimensions for present intervention and further exploration. Building upon an earlier formulation, an hypothesized model is presented which combines these elements for explaining and predicting compliance behavior. Further research should, with standardized questionnaires and analysis techniques, employ prospective, experimental designs for a variety of population groups, settings, and regimens, to evaluate the ability of practical attempts to modify the model variables and thus enhance compliance.

Attendance patterns and characteristics of participants in public cholesterol screening.

We conducted free, voluntary, public cholesterol screenings in supermarkets in the Rochester, New York, area during a four-month period for demonstration and research purposes. We assessed demographic characteristics and attendance patterns of the 8,583 participants. Compared with 1980 census data for the same census tracts, our participants were likelier to be white, older, female, and better educated than the general population in the area. Most screenees knew about the screenings in advance, and 79% came to the store just for screening. Weekend and weeknight screenings attracted more men and more younger people, in comparison to weekday screenings. However, referral rates based on high cholesterol (HC) test results were similar during all screening times. Overall, 22% of screenees reported a previous diagnosis of HC, but in the highest cholesterol-level group, 45% of screenees reported a history of HC. Previous awareness of HC did not vary according to screening time. These findings indicate that, like other screenings, cholesterol screenings in a public setting do not attract a representative sample of the whole population. The screenings did, however, attract a large number of high-risk individuals, many of whom had no prior awareness of HC. These results should be valuable in planning and targeting future cholesterol screenings.

Patterns of physicians' treatments for referral patients from public cholesterol screening.

Current interest in high blood cholesterol and attendance at public cholesterol screening programs has raised the issue of whether physicians are responding to referrals according to existing national assessment and treatment recommendations. This study assessed the relationship of characteristics of referrals from a series of public blood cholesterol screenings to physicians' treatment practices. For this analysis, the sample was restricted to 1,324 subjects, from the 2,109 referred, who reported seeking physician care. At five months after screening, 75% of subjects reported their physician prescribed a diet; 16% of physicians prescribed medication. Multiple logistic regression, adjusted for sociodemographic characteristics and other coronary heart disease (CHD) risk factors, indicated that screening cholesterol risk level, prior history of high blood cholesterol levels, and type of medical contact were consistently related to receipt of diet and medication treatment, but other CHD risk factors were underutilized. "Moderate" risk subjects with no history of high blood cholesterol were less likely to have received dietary advice, but a screening-risk level interaction did not occur for medication. The results imply that current treatment guidelines may not be working and suggest the need for continued physician education in the management of hypercholesterolemia.

Effects of sociodemographic and attitudinal factors on mother-initiated medication behavior for children.

Little is known about the therapies that people initiate for their health problems, and the available research on self-medication has focused primarily on adult populations. Only a few studies have specifically addressed mothers' independent use of medications for their children, and none has described such behavior in depth (for example, relating-perceived symptoms and conditions in the child or attempting to provide an explanation for mothers' decisions in these situations). A stratified systematic random sample of 100 mothers of children between 6 months and 12 years old was obtained at each of 3 pediatric ambulatory care clinics. Mothers were interviewed about their use of medications for their children, their concerns about their children's health, and their medication-related attitudes. The study results suggest that income and education are related to the types of medication and medical appliances mothers keep to treat the various health problems of their children. Mothers' perceptions of their children's potential susceptibility to health problems are related to possession of what they believe are relevant remedies for those problems (as well as to keeping a greater variety of medications on hand). Socioeconomic status appears to be one determinant of the number of different remedies (and especially the number of different medical appliances) that are purchased. Certain attitudes held by mothers about medications also play a role in explaining how great a variety of remedies are kept available for children in the event that they become ill, and these medication-related attitudes are highly correlated with socioeconomic status.

Public cholesterol screening in the previously diagnosed: misuse of resources or beneficial function?

The attendance of individuals with a previous diagnosis of hyperlipidemia at public cholesterol screenings is often criticized as a misuse of such programs. This study explored the post-screening actions of 811 participants in a cholesterol screening program who had previously been diagnosed with cholesterol elevations and whose blood levels at this screening required further medical referral. We also studied the responses of physicians from whom these subjects sought care. Within five months, 559 of 753 participants completing the survey (74.0%) sought medical follow-up. Physicians retested the blood cholesterol levels of 75.0% of these 559; high-risk screenees were more likely to be retested and to be informed that their levels were elevated than moderate-risk subjects (P < .0001). Physicians increased cholesterol-lowering dietary advice for high-risk subjects (P < .0001) and medication prescriptions for both risk groups (P < .0001). Participants seeking medical care after the screening program had better cholesterol-lowering dietary practices and reported increased regimen compliance (moderate-risk: P = .01; high-risk: P < .0001) than those individuals not obtaining medical follow-up. One year after screening, blood cholesterol levels were 4.5% lower (P = .001) in those complying with referral but were virtually unchanged in noncompliers. Screening program confirmation of high blood cholesterol levels combined with referral appeared to have a positive impact on previously diagnosed screenees. We conclude that there may be merit in including previously diagnosed individuals in cholesterol screening programs.
