摘要

The purose of this study was to test the relation ships between perceived self-efficacy, functional staus and depression in a group of chronic heart fail re patients. The coneptual model for this study was primarily derived from Bandura’ s social learning theory. The study is based on an explorabry, correlational design. A sample of 100 chronic heart failure patients who met the inclu sion cri t eriawere recruited from four car diovas cular clinics of major hospitals in northern Taiwan. The insiruments used in this study included Jenkins’ Self-Efficacy Expec ta tion Scales, Seat tle Angina Inven tory, and Geriatric Depres sion Scale. Results dem on strate a sig nifi cant inverse rela tion ship between per ceived self-efficacy and depres sive symp toms (r(subscript _)=-.61, p(subscript _)＜.001), a sig nifi cantpos itive relation ship between per ceived self-efficacy and func tional sta tus (r(subscript _)=.55, p(subscript _)＜.001), and a sinifi cantneg ative relation ship between functional status and depressive symptoms (r(subscript _)=-.33,p(subscript _)＜.001). The findings of the path analysis sup port the hypoth esis that afier con troll ling for disease severity, perceived self-efficacy has a direct and negative effect on depressive symptoms. An indirect effect of perceived self-efficacy on depression through functional status in heart failure patients was also revealed in the finding. All paths in the model were signifi cant (p(subscript _)＜.05). Results of the study can help to identify heart failure patients who are at risk for low perceived self-efficacy, low functional status, and a depressed mood. Nursing intervention to address these factors can then be developed and tested.
