Evaluating the effect of Pender's health promotion model on self-efficacy and treatment adherence behaviors among patients undergoing hemodialysis.

Abstract

INTRODUCTION:Health promotion through lifestyle improvement is an important topic that has received considerable attention from the scientific community worldwide. This study aimed to determine the effect of Pender's health promotion model on self-efficacy and treatment adherence behaviors of hemodialysis patients in Shahrekord, Iran, in 2018–2019.METHODS:This quasi-experimental study was performed on 70 hemodialysis patients who were attending routine hemodialysis sessions in Hajar hospital in Shahrekord. Individuals were selected by simple random sampling and randomly assigned to two groups of control and intervention. In the preintervention stage, all patients completed a questionnaire that was prepared to collect demographic information and measure health-promoting behaviors, self-efficacy, and treatment adherence. The intervention group participated in eight sessions of a health promotion model-based education program. Both groups were asked to complete the questionnaire again immediately after the intervention and also 2 months later.RESULTS:The repeated measures analysis of variance (ANOVA) showed a significant difference between the two groups in terms of the extent of change in mean scores over the three measurement stages (before the intervention, after the intervention, and 2 months after the intervention) (P < 0.001). A statistically significant difference was observed between the two groups in terms of self-efficacy scores in the postintervention and follow-up stages (P < 0.05). The repeated measures ANOVA also revealed a significant difference between the two groups in terms of the extent of change in mean treatment adherence scores over the three measurement stages (P < 0.001).CONCLUSION:Considering the positive effects of the program on patients undergoing hemodialysis, it is recommended to use the program to promote the well-being of these patients without time restrictions.
