概要	It is necessary to assess functional impairment when treating schizophrenia. The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) has been adopted as a measure of functional disability in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition. This study was a secondary analysis from a cross-sectional study of health-related behaviors among patients with schizophrenia. We examined the validity and reliability of the Japanese version of the 12-item WHODAS 2.0 when self-administered by such patients. Participants were 350 outpatients with schizophrenia from a psychiatric hospital. The standard six-factor structure of the WHODAS 2.0 showed a good fit for these participants. The Cronbach's alpha coefficient was 0.858, showing good internal consistency. The WHODAS 2.0 showed moderate correlations with the modified Global Assessment of Functioning and Kessler 6 scales (r=-0.434 and 0.555, respectively). The results of this study show that the Japanese version of the 12-item self-administered WHODAS 2.0 has good internal consistency and convergent validity among patients with schizophrenia. Further exploration of the usefulness of WHODAS 2.0 in clinical settings is needed.
