Impact of Type D Personality, Role Strain, and Diabetes Distress on Depression in Women With Type 2 Diabetes: A Cross-Sectional Study.

Background: Women with diabetes face a significantly elevated risk of developing depression. Clarifying the factors associated with depression is critical to designing more timely interventions for this vulnerable population.

Purpose: This study was developed to examine the impact of Type D personality, diabetes-care-related role strain, and diabetes-related distress on depression in women with Type 2 diabetes.

Methods: A cross-sectional design was used. Convenience sampling was used to recruit 298 women aged 20-64 years who had been diagnosed with Type 2 diabetes for over 6 months from three outpatient endocrine clinics in Taiwan. Demographic and disease characteristics and Type D personality (negative affectivity and social inhibition), diabetes-care-related role strain, and diabetes-related distress and depression status information were collected using self-reported questionnaires and medical records. The important factors of influence on depression were examined using hierarchical multiple regression.

Results: On the basis of the results of the hierarchical multiple regression analysis, age, negative affectivity, diabetes-care-related role strain, and diabetes-related distress were identified as significantly associated with depression, with negative affectivity explaining most (43.4%) of the variance in depression, followed by diabetes-care-related role strain and diabetes-related distress, which respectively explained 3% and 2.5% of the variance.

Conclusions/implications for practice: The negative affectivity associated with the Type D personality was shown to be more significantly associated with depression than diabetes-related psychosocial factors such as diabetes-related distress and diabetes-care-related role strain. Timely assessment of negative affectivity and the provision of brief mindfulness intervention to reduce negative affectivity may be useful in preventing depression in women with Type 2 diabetes, whereas addressing diabetes-related distress and diabetes-care-related role strain should not be neglected when providing comprehensive depression-preventing interventions to young women with diabetes.
