Abstract:
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.
