Investigating the effect of educational intervention based on the Pender’s health promotion model on lifestyle and self‑efficacy of the patients with diabetic foot ulcer: A clinical trial

This study aimed to investigate the effect of educational intervention based on the Pender’s health promotion model (HPM) on lifestyle and self‑e fficacy of the patients with diabetic foot ulcer.

In this clinical trial conducted in 2019, 74 patients based on inclusion criteria were selected through convenience sampling and allocated to two groups of intervention (n = 37) and control ( n = 37) using the randomized permuted block method. In this study, Demographic characteristics and localized Diabetes Foot Care Self ‑Efficacy Scale and Health‑Promoting Lifestyle Profile Questionnaire for diabetic foot care were completed by two groups. The obtained data were analyzed using SPSS 16 and through descriptive and comparative statistics, independent t‑test, paired t‑test, and ANCOVA.

After the intervention, the mean score of the intervention group significantly increased in all lifestyle dimensions (P < 0.001). Furthermore, the mean score of self‑effcacy increased in the intervention group after the intervention (P < 0.001). Comparing the change in the mean scores of lifestyle and self‑efficacy in both the groups 50 days after the intervention, an increase was observed in the mean scores of self‑efficacy (P < 0.001) as well as those of lifestyle and its dimensions in the intervention group compared to those in the control group (P < 0.001).

Educational intervention based on the Pender’s HPM can promote the self‑efficacy, lifestyle, and its dimensions in the patients with diabetic foot ulcers. The results of this study can be used in educational interventions aiming at patients with diabetic foot ulcers to change their lifestyle and improve their self‑efficacy.
