Reliability and Validity of the Korean version of Richmond Compulsive Buying Scale

Objectives The purpose of this study was to evaluate the psychometric properties of the Korean version of the Richmond Compulsive Buying Scale (RCB-K). Methods Participants (n=598) included patients recruited through an online panel survey. For the semantic adaptation step, the scale was translated into Korean and then back-translated to English by one psychologist, one public health professional, one psychiatrist who could speak both Korean and English, and one professional translator, without communication between those involved. A confirmatory factor analysis was performed to test whether the factor structure of the RCB-K was consistent with the English version. Convergent validity was assessed by correlating the RCB-K scores with those of other scales (i.e., O Guinn & Faber s Compulsive Buying Scale, Problem Gambling Inventory). Results The factor structure of the RCB-K was consistent with the two-factor structure established for the original RCB. Cronbach s α was high (0.906), indicating that the reliabilities of the items in each subscale were satisfactory. The RCB-K score was significantly correlated with those for the O Guinn & Faber s Compulsive Buying Scale (r=0.7) and the Problem Gambling Inventory (r=0.422). Conclusion The results of the present study indicate that the RCB-K is an effective and valid scale for evaluating the severity of compulsive buying. The findings suggest that the RCB-K is a promising assessment tool for use in the treatment and study of online compulsive buying behavior.
