Correlation between Self Efficacy, Type D Personality and Health Locus of Control with Control of Blood Sugar in Patients with Diabetes Type II

Introduction: Glycemic control in type 2 diabetic patients seems to be affected by personality as well as psychological factors. Therefore, this study intends to investigate the relationship between self efficacy, type D personality and health locus of control with control of blood sugar in patients with diabetes type 2. Methods: All women with diabetes in Yazd Diabetes Research Centre were considered among which 80 were selected by random sampling. They completed Shirer’s self-efficacy scale questionnaire, type D personality questionnaire and Multiple health locus of control questionnaire. Then they were introduced to the lab for blood test. Data was analysed by SPSS software and stepwise regression method. Results: The results of Pearson correlation coefficients showed that self efficacy (r = 0/83) and type D personality (r=0/55) and health locus of control with HbA1c correlated positively and significantly (p <0/05). Stepwise regression analysis showed that R2=0/73; In other words, 73% changes of the variable HbA1is determined by self-efficacy, type D personality and health locus of internal control variables Conclusion: Impact of personality and psychological variables in diabetes glycemic control is important. So we can implement interventions to increase the efficacy of internal control sites and modify the features of type D personality in patients with diabetes and thus to improve glycemic control and adherence to treatment regimens in these patients.
