Relationships among preventive behavioral model concepts in individuals at risk for coronary artery disease

Abstract

The Purpose of this research was to describe relationships between Murdaugh and Verran's (1987) Preventive Behavior Model Concepts in military-affiliated individuals at risk for coronary artery disease. One hundred forty-three subjects were recruited by their primary care physician and were requested to voluntarily complete questionnaires measuring health beliefs, health locus of control, value orientations, and health care activities. Laboratory values and blood pressure were also evaluated. There were significant positive correlations between health beliefs, health locus of control, and value orientations. However, these PBM concepts explained only 13% of the variance in dietary habits, 9% of smoking behaviors, 16% of habitual physical activity, 4% of cholesterol levels, 2% of diastolic blood pressure, 7% of body mass index, and 21 percent of glucose levels. PBM concepts explained a relatively small amount of the variance in the dependent variables within this sample and the results were not clinically significant.
