Benefits of group compassion-focused therapy for treatment-resistant depression: A pilot randomized controlled trial.

Major depression is one of the most common mental health problems worldwide. More than one-third of patients suffer from treatment-resistant depression (TRD). In this study, we explored the feasibility of group compassion-focused therapy (CFT) for TRD using a randomized controlled trial with two parallel groups. Eighteen participants were randomly allocated to the intervention group (CFT and usual care) and control group (usual care alone) and a participant in each group withdrew. Participants in the intervention group received a 1.5-h session every week for 12 weeks. The effects of the intervention on the participants' scores were calculated using a linear mixed model. There was a larger reduction in their depressive symptoms and fears of compassion for self and a greater increase in their compassion for self compared to the control group participants. The reliable clinical indices showed that in the CFT (intervention) group, three of nine participants recovered (33%), two improved (22%), two recovered but non-reliably (22%), and the condition of two remained unchanged (22%). These findings indicate adequate feasibility of group CFT for TRD in Japanese clinical settings. Clinical trial registration: [https://clinicaltrials.gov/], identifier [UMIN 000028698].

Development of the Japanese version of the Other As Shamer Scale using item response theory.

OBJECTIVE: External shame reflects a person's anxiety that he or she might be rejected by others. The Other as Shamer Scale (OAS) is a scale for assessing external shame. The Japanese version of the OAS was developed, and its reliability and validity were examined using Item Response Theory (IRT). RESULTS: A survey was conducted with university students (N = 199). Exploratory factor analysis of the results indicated a significantly high factor loading on the first factor, which was identical to the original version of the scale as well as high internal consistency. Moreover, the results confirmed that each item had adequate discrimination and information levels, suggesting that external shame could be discriminated against with high accuracy for a wide range of relatively low and relatively high external shame groups. These results suggest that the OAS could be used to screen external shame as a stress factor and to assess intervention effects.
