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

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
