Psychometric evaluation of the Mandarin Chinese version of the Yale-Brown Obsessive-Compulsive Scale–Self Report

Abstract Objective The psychometric properties of the Mandarin Chinese version of the Yale-Brown Obsessive Compulsive Scale–Self Report (Y-BOCS-SR) were examined. Method Participants included 80 outpatients with a primary diagnosis of obsessive compulsive disorder. Measures included the Mandarin Chinese version of the Yale-Brown Obsessive-Compulsive Scale–Self Report, the Yale-Brown Obsessive-Compulsive Scale–II (clinician rated), the Clinical Global Impression, and the Depression Anxiety Stress Scales–21. Internal consistency was calculated with the Cronbach's alpha coefficient, Pearson's correlations were examined between the measures, and confirmatory factor analyses and a subsequent exploratory factor analysis were performed. Results Results indicated good internal consistency. Correlations with other measures were as expected and indicated good convergent and divergent validity. The Y-BOCS-SR performed similarly to the Y-BOCS-II with regard to correlations with other measures. Confirmatory factor analysis revealed poor model fit for all tested models. An exploratory factor analysis indicated a single factor solution instead of the more traditional two-factor solution. Conclusions Overall, the findings provide evidence for good psychometric properties of the Mandarin Chinese version of the Y-BOCS-SR. Future research is needed to better explore the factor structure of the measure, examine other types of reliability and validity, and to increase the generalizability of the findings.
