The objective of the present study was to investigate the factor structure, and the reliability and validity of the Japanese version of the Obsessive-Compulsive Inventory-Revised (OCI-R). The participants included 214 university students enrolled at two universities in a metropolitan area. They completed the OCI-R and other related scales, and of these, 38 students answered the OCI-R again two weeks later. Based on a factor analysis, the six-factor structure, the same as the original version, was confirmed. For reliability, internal consistency and test-retest reliability were evaluated and both internal consistency and test-retest reliability were confirmed. For convergent validity, we calculated the correlation coefficient using the Japanese version of the Maudsley Obsessional-Compulsive Inventory, which measures obsessive-compulsive symptoms. For concurrent validity, we calculated the correlation coefficient using the Patient Health Questionnaire-9, which measures depressive symptoms; and the Generalized Anxiety Disorder-7, which measures anxiety symptoms. Overall, the factor structure, the reliability, and the validity of the Japanese version of the OCI-R were all confirmed in this study. In the future, we will investigate whether the same results can be obtained in clinical groups.

Aim Utena's Brief Objective Measures (UBOM) was developed to assess psychophysiological functions proximal to real-world functioning in individuals with psychiatric disorders, including schizophrenia (SCZ), to facilitate shared decision-making. However, the validity of UBOM has not been fully examined. Methods We conducted a cross-sectional observational study to evaluate the validity of each of the three tests in UBOM: UBOM-Pulse, UBOM-Ruler, and UBOM-Random. We investigated associations: (i) between UBOM and existing cognitive- and autonomic-function tests; and (ii) between UBOM and daily social functioning. The participants included SCZ individuals and healthy controls. We evaluated the cognitive and autonomic function using UBOM, the heart rate variability test, the simple reaction time test, and the Brief Assessment of Cognition in Schizophrenia, Japanese version. We also assessed the daily social functioning using the WHO Disability Assessment Schedule 2.0 and the modified Global Assessment of Functioning, Japanese version. Results Thirty-one SCZ individuals and 35 healthy control individuals participated in this study. In the SCZ group, UBOM-Ruler was significantly associated with the Cognition and Getting Along domains of WHO Disability Assessment Schedule 2.0. UBOM-Random was significantly associated with the Brief Assessment of Cognition in Schizophrenia's Working Memory, Verbal Fluency and Attention domains, and the modified Global Assessment of Functioning in the SCZ group. Conclusion The validity of the current version of UBOM is imperfect and further improvements will be necessary to attain the originally intended goal of developing a brief assessment tool for real-world functioning in SCZ.

Aims: Cognitive behavioural therapy (CBT) is one of the evidence-based treatments for depression. However, some patients high in self-criticism do not respond to CBT. Compassionfocused therapy (CFT) is featured in treating self-criticism and shame, and some trials have reported its effectiveness on depression in individual and group settings. The aim of this study is to adapt an established combined manual of group CBT and CFT, evaluate its efficacy as a pilot study, and discuss the advantages of group CBT (GCBT) program using compassion as a depression therapy in a Japanese community setting. Study Protocol Article Asano et al.; BJMMR, 9(10): 1-5, 2015; Article no.BJMMR.19206 2 Design and Methods: In this single group study, participants will receive 10 sessions of GCBT with compassion training that was provided through the CFT. All sessions will last for 1 hour and be provided weekly. The outcome measure is the Beck Depression Inventory II, and the secondary outcome is the Self-Compassion Scale in Japanese. Both outcomes will be measured preand post-program. The sample size will be 15 participants due to the limited capacity for intervention within the community. Discussion: It is expected that the program will show a larger effect size than that of GCBT reported in previous studies on depression and self-compassion. The results will show an effect size that justifies the introduction of a randomized controlled study to improve the program.

Conclusion: CFT or compassion training can augment the treatment of major depression using CBT. Despite several limitations, this clinical trial may help estimate the effectiveness of CFT, which will aid in the design of a further controlled study.

Objective 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. Results 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
