한국판 리치몬드 강박구매 척도의 타당도, 신뢰도 연구

Abstract

ObjectivesZZThe purpose of this study was to evaluate the psychometric properties of the Koreanversion of the Richmond Compulsive Buying Scale (RCB-K).MethodsZZParticipants (n=598) included patients recruited through an online panel survey. Forthe semantic adaptation step, the scale was translated into Korean and then back-translated toEnglish by one psychologist, one public health professional, one psychiatrist who could speakboth Korean and English, and one professional translator, without communication between thoseinvolved. A confirmatory factor analysis was performed to test whether the factor structure of theRCB-K was consistent with the English version. Convergent validity was assessed by correlatingthe RCB-K scores with those of other scales (i.e., O’Guinn & Faber’s Compulsive Buying Scale,Problem Gambling Inventory).ResultsZZThe factor structure of the RCB-K was consistent with the two-factor structure establishedfor the original RCB. Cronbach’s α was high (0.906), indicating that the reliabilities of theitems in each subscale were satisfactory. The RCB-K score was significantly correlated with thosefor the O’Guinn & Faber’s Compulsive Buying Scale (r=0.7) and the Problem Gambling Inventory(r=0.422).ConclusionZZThe results of the present study indicate that the RCB-K is an effective and validscale for evaluating the severity of compulsive buying. The findings suggest that the RCB-K is apromising assessment tool for use in the treatment and study of online compulsive buying behavior.
