Psychosocial Predictors of Diabetes Risk Factors and Complications: An 11-Year Follow-Up

Objective: The goal of this study was to use the risk and resistance framework to examine whether a set of psychosocial variables measured at age 12 in youth with Type 1 diabetes would predict the emergence of diabetes risk and complication variables 11 years and 13 years later. Method: We interviewed youth with Type 1 diabetes when they were average age 12 and followed them for 11 years until they were average age 23 and then average age 25. At age 12, we measured personality traits (unmitigated communion, unmitigated agency), relationship variables (parent relationship quality, friend support, friend conflict), indicators of psychological well-being (depressive symptoms, bulimic symptoms, self-worth), and self-care behavior. We used these psychosocial variables assessed at age 12 to predict diabetes risk factors, glycemic control, and the emergence of diabetes complications at follow-up. Results: Higher unmitigated agency, poor quality parent relationships, higher friend conflict, bulimic symptoms, and lower self-worth predicted one or more diabetes outcomes. When statistical controls for age 12 glycemic control were employed, unmitigated agency emerged as the most robust predictor of diabetes outcomes. Conclusion: Unmitigated agency, which involves an overly inflated view of the self and a cynical view of others, predicted poor diabetes outcomes over an 11-year and 13-year period. The processes by which unmitigated agency could influence health are discussed.
