Shared and Differential Psychological Processes Associated With Treatment Response in Mindful Self-Compassion and Cognitive-Behavioural Therapy for Chronic Pain: An Exploratory Secondary Analysis of a Randomized Controlled Trial

Background

Psychological treatments for chronic pain are effective, but the processes associated with therapeutic change, and whether these are shared across treatments or treatment-specific, remain unclear. This exploratory secondary analysis examined whether changes in pain acceptance, pain catastrophizing facets and self-compassion were associated with clinical outcomes in Mindful Self-Compassion (MSC) versus Cognitive-Behavioural Therapy (CBT).
