Group cognitive behavioural therapy with compassion training for depression in a Japanese community: a single-group...

Depression is a representative mental problem, and more than 350 million people are suffering in the world. Cognitive behavioural therapy (CBT) in individual or group formats is mainly recommended in major guidelines. However, patients with high self-criticism have a poor response to CBT. To treat such patients, psychotherapies focusing on compassion are gaining attention. Although trials have begun to be reported, there are relatively few studies examining the effectiveness of group CBT with compassion work for managing depression. The purpose of this study was to evaluate the feasibility and acceptability and the estimate effect size of group CBT with compassion training for future controlled studies.

Fourteen participants were enrolled in the trial, of which 13 completed the intervention, and 12 completed a 6-month follow-up assessment. Participants received a 1 h group-based CBT with compassion training session every week for 10 weeks. The effect of the intervention on participants' Beck Depression Inventory score was examined using a general linear mixed model. This analysis showed an effect size of d = 1.12 at post intervention and d = 0.92 at 6-month follow-up. Group cognitive behavioural therapy with compassion training for depression shows feasibility and acceptability in a Japanese community. Trial Registration UMIN000015007.
