Description: The purpose of this study was to determine if there was a significant relationship among coronary artery disease (CAD) knowledge, anxiety, social support, and self-efficacy and the adaptive health behaviors of diet, exercise, and smoking for patients treated with a percutaneous transluminal coronary angioplasty (PTCA). The Roy Adaptation Model served as the conceptual framework. Bandura's Social Cognitive Theory was used to hypothesize an influence of self-efficacy on adaptive lifestyle changes.

A convenience sample of 82 first-time PTCA patients was included in this study. Instruments utilized included a demographic form, the Coronary Angioplasty Risk Factor Inventory (Murphy, & Fishman, & Shaw, 1989), the State-Trait Anxiety Inventory (Form Y) (Spielberger, 1983), the Cardiac Diet Self-Efficacy Instrument (Hickey, Owens, & Froman, 1992), the Cardiac Exercise Self-Efficacy Instrument (Hickey et al.), the Self-Efficacy for Smoking Avoidance Instrument (DiClemente, 1981), the University of Alamba at Birmingham (UAB) Food Frequency Checklist, an exercise frequency checklist, and an interview form.

Data were analyzed using descriptive statistics, correlations, factor analysis, t tests, stepwise multiple regression, and canonical correlation. Results indicated that the four predictive variables of CAD knowledge, anxiety, social support, and self-efficacy all had an influence on one or more of the adaptive health behaviors of diet modification, exercise, and smoking. Self-efficacy was the single most predictive variable that was consistently related to adaptive behavior. Anxiety in combination with self-efficacy was found to have the most significant relationship with change in the subjects' adaptive behaviors.

Implications of this study include: (a) use of screening procedures to identify anxiety and self-efficacy levels in patients treated with a PTCA, (b) nursing care focused on lowering patients' anxiety while increasing their self-efficacy, and (c) qualitative studies to identify patients' perceptions of reasons for adaptive or ineffective health behaviors after a PTCA.
