Relationships Among Locus of Control, Psychology Status and Glycemic Control in Type 2 Diabetes

Purpose:

 The purpose of this study was to determine whether the factors of locus of control, self-efficacy, depression, and self-care behavior relate to glycemic control in type 2 diabetes.

Methods:

  We used a descriptive correlational design. Convenience sampling was applied to enroll 285 subjects from diabetic outpatient clinics in Southern Taiwan. We applied the locus of control, self-efficacy, depression, and self-care behavior questionnaires. Glycemic control was assessed by HbA1c measures.

Results:

 The internal locus of control was significantly positively correlated with self-efficacy and self-care behavior, and significantly negatively correlated with depression. combined depression and self-efficacy partly mediated the relationship between internal locus of control and self-care behavior (P<.01), and completely mediated the relationship between external locus of control and self-care behavior (P<.01). Depression and baseline HbA1c directly and significantly affected HbA1c post value. Higher depression had the worst HbA1c levels. We integrated optimal self-care behavior requiring a high internal locus of control, self-efficacy, and low depression to influence enhanced glycemic control.

Conclusion:

This finding could form a basis for caring people with type 2diaberes and provide a reference for further research.
