Psychosocial determinants of self-care behavior in outpatients with heart failure : a test of Pender s health promotion model

الملخص EN

Background: Patients with heart failure need to be engaged in adequate cardiac self-care behaviors helping to prevent the development of the disease and ameliorate their health status.

However, the conceptual model of the present study has not been tested in previous studies among patients with heart failure.

Objectives: The present study aimed to investigate the psychosocial determinants based on Pender’ s health promotion model (HPM) affecting self-care behavior among outpatients suffering from heart failure.

Methods: In this cross-sectional study, a total of 200 patients suffering from heart failure were selected from the outpatient clinics of Tabriz, Iran, using convenience sampling and assessed for self-self-care behaviors and major concepts of HPM via self-administered questionnaires.

Path analysis was used in order to analyze the conceptual model.

Results: The present hypothetical model showed a good fit.

Perceived benefits and activity-related affect directly affected self-care behaviors.

Bootstrapping mediation analyses indicated that perceived self-efficacy, perceived barriers, perceived benefits, and activityrelated affect indirectly affected self-care behaviors through commitment to action.

Conclusion: The commitment to action can help to promote self-care behaviors among the subjects suffering from heart failure.

The interventions should take the role of predictive variables of this study and commitment to action into account in these patients.
