Compr Psychiatry. 2012 Jul;53(5):600-8. doi: 10.1016/j.comppsych.2011.09.006. Epub 2011 Nov 21.


This study examined the reliability and validity of the Japanese version of the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM), a standardized, brief, but comprehensive outcome measurement. The target population consisted of 1684 Japanese company employees, hospital staff, and university students. A confirmatory factor analysis proved that our data fit the factor structure of the original CORE-OM. We also examined its internal consistency, test-retest reliability, convergent validity, and sensitivity in discriminating between clinical and nonclinical samples. After demonstrating these results, we discuss how the Japanese version of the CORE-OM can be used both in clinical and research settings.
