Intrinsic motivation in ethnic minority youth with type 1 diabetes

Abstract

Increasing intrinsic motivation (IM) may be an effective way to improve regimen adherence and glycemic control in youth with type 1 diabetes (T1D). This preliminary study evaluated the reliability and validity of a new measure of intrinsic motivation for diabetes management for ethnic minority youth with T1D. The 12-item Intrinsic Motivation Inventory for Diabetes Management (IMI-DM) was developed to assess perceptions of confidence in and the importance of engaging in self-care behaviors for diabetes management. Participants included 51 11-16 year-old minority adolescents (M age = 13.5 years) with T1D and their parents. The IMI-DM demonstrated excellent internal consistency (α=.92). Higher IM was associated with better diabetes self-management behaviors and glycemic control, better youth self-concept, less depression and family conflict, and greater youth responsibilities for diabetes management. These findings provide preliminary support for the reliability and validity of a new diabetes-specific IM measure for youth with T1D, and identified some key individual and family factors that may be important to consider in interventions to improve regimen adherence and glycemic control in minority youth with T1D.
