Impact of Individual Motivational Interview Based on Self-care on the Treatment Adherence of Type II Diabetic Patients

Adherence of type II diabetic patients to treatment is very important in preventing the complications of this disease. Furthermore, a motivational interview is an intervention considered to change health behaviors. Therefore, the current study aimed to determine the impact of the motivational interview based on self-care on the treatment adherence of type II diabetic patients hospitalized in Nabi Akram hospital in Zahedan, Iran, in 2018.

In this semi-experimental study, 40 diabetic patients were selected and randomly divided into intervention (n=20) and control (n=20) groups. Data collection tools for this study were demographic questionnaire and adherence questionnaire in patients with chronic diseases. The intervention group received four sessions of individual self-care motivational interview training. Moreover, the control group received similar training content during four sessions in the usual face-to-face manner without applying the principles of motivational interview. Adherence was measured in both groups 8 weeks after the termination of intervention. Then, the collected data were analyzed by the independent t-test and analysis of covariance using SPSS software (23).

After the intervention, the mean adherence score of diabetic patients in the intervention group (150/57) was significantly higher than the mean score of the control group (141/27) (P<.001).

Motivational interview training based on self-care has positive impact on the adherence of type II diabetic patients to treatment. Therefore, the nurses are suggested to apply the principles of motivational interview while training these patients.
