The Effect of Educational Program Based on the Extended Theory of Reasoned Action on Self-Care Behaviors in Women with Type 2 Diabetes

BACKGROUND AND OBJECTIVE: The aim of this study is to determine the effect of educational program based on the extended theory of reasoned action on self-care behaviours in women with type 2 diabetes in Fasa. This quasi-experimental study was performed on 100 women with type 2 diabetes who referred to diabetes clinics in Fasa. MATERIALS AND METHODS: Samples were randomly divided into experimental and control groups. The data were collected using a questionnaire based on the extended theory of reasoned action and self-care behaviours that were completed by both the control and experimental groups before and 3 months after the educational intervention. Data were analysed by SPSS software version 22, descriptive statistics tests, Chi-square test, independent T-test, and paired T-test. RESULTS: The results of the study showed that after the educational intervention, the mean scores of all constructs of the extended theory of reasoned action in the experimental group were significantly increased compared to the control group (P <0.05). CONCLUSION: Also, the educational intervention had a significant effect on the promotion of patient's self-care behaviours in the experimental group and the HbA1c level decreased in the experimental group compared to the control group (P <0.05). In addition, it was found that the extended theory of reasoned action could be a suitable framework for designing educational interventions for promoting self-care behaviours in diabetic patients.
