PURPOSE:The purpose of this study was to identify influencing factors on health behavior adherence in middle and old aged men who underwent percutaneous coronary intervention.

METHODS:With a convenience sampling, data were collected from 140 middle and old aged men who underwent percutaneous coronary intervention at two general hospitals. A structured questionnaire was used to measure husband-wife harmony, self-efficacy, and behavior adherence. Data were analyzed by descriptive statistics, Pearson's correlation coefficient, and stepwise multiple regression.

RESULTS:Health behavior adherence was significantly correlated with husband-wife harmony (r=.59, p<.001) and self-efficacy (r=.54, p<.001). There was also a significant correlation between husband-wife harmony and self-efficacy (r=.48, p<.001). Overall, approximately 43.7% of the variability in health behavior adherence was explained by these two variables in this study (F=54.85, p<.001).

CONCLUSION:The findings suggest that husband-wife harmony and self-efficacy could be important factors affecting health behavior adherence in middle aged men who underwent percutaneous coronary intervention. Therefore, nursing interventions for them should focus on increasing husband-wife harmony and self-efficacy.
