Abstract

Objectives: This study aimed to identify clusters of participants with Type 2 diabetes mellitus (T2DM) at risk for developing psychological and somatic distress symptoms. Moreover, we investigated whether the different clusters were associated with glycemic control, sleep, and physical activity levels. Design and main outcome measures. In a cross-sectional design, participants with T2DM (n = 269) completed questionnaires on psychological and somatic distress, sleep disorders and physical activity.

Results: Cluster analyses yielded three groups: a) "high self-confident and low demoralised"; b) "low support and low involvement"; c) "high consequences, high demoralisation and nagging". The groups were distinguished by the social, cognitive, and vital exhaustion variables and significant differences in diabetes-related psychological distress and physical activity. The measure of glycemic control did not differ between clusters. The "high self-confident and low demoralised" group displayed the lowest scores on psychological distress compared to the other clusters.

Conclusions: Results suggest that social cognitive dimensions and affective states play a key role in defining clusters in participants with T2DM. Thus, we need to consider the psychological profiles of participants with T2DM when designing interventions to improve self-management strategies.
