Group counseling in cardiac rehabilitation: effect on patient compliance

Abstract

A multicenter clinical trial was conducted to evaluate the effects on compliance of a group counseling program for cardiac patients and spouses. The sample comprised 58 couples in which one of the partners had documented atherosclerotic heart disease and was enrolled in an outpatient cardiac rehabilitation program. The experimental intervention involved a ten-week series of group sessions based on symbolic interactionist role theory. The research used a quasi-experimental, three-group, time-series design: Experimental group 1 consisted of 17 patients and their spouses who participated in group counseling; experimental group 2 consisted of 22 patients and their spouses, but only the patients participated in the group series; the control group consisted of 19 patients and their spouses who did not participate in the experimental program. Data were collected at baseline, ten weeks, and six months on four cardiac risk factors: weight loss, blood pressure, exercise, and smoking. Repeated measures analysis of variance showed a significant difference (P less than 0.01) in mean body fat among treatment groups, with experimental group 2 having the greatest decrease over time. Patients in both experimental groups demonstrated lowered blood pressure, with a significant decrease (P less than 0.05) in systolic blood pressure. Again, the largest decrease was in experimental group 2. Changes in weekly exercise level were not significantly different among groups, although the highest compliance was reported by experimental group 1 patients. Results support the efficacy of group counseling based on an interactionist role theory framework to increase compliance. The anticipated effect of spouse participation was not confirmed.
