Self-Efficacy as a Central Mediator of Pain, Function, and Depression: Insights of a Cross-Sectional Analysis of Depersonalized Data from the German Pain e-Registry

This large real-world cohort demonstrates a highly coherent pattern of associations across biopsychosocial domains and highlights pain-related self-efficacy as a central statistical construct linking pain, functional impairment, and depressive symptom burden within the applied exploratory models. The findings suggest that self-efficacy occupies a key position in the interplay between pain and mood, and that pharmacological and non-pharmacological treatments traditionally used in chronic pain management may be associated with changes in this construct. Importantly, all directional and mediation analyses are exploratory and do not imply causal or mechanistic relationships. Therapeutic strategies aimed at enhancing self-efficacy may therefore represent promising targets for future research within multimodal pain management frameworks.
