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

Abstract

ObjectivesZZThe purpose of this study was to evaluate the psychometric properties of the Korean version of the Richmond Compulsive Buying Scale (RCB-K).MethodsZZParticipants (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).ResultsZZThe 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).ConclusionZZThe 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.

Adaptation and validation of Richmond Compulsive Buying Scale in Chinese population

“…The results of this study contribute to the findings of extant literature on the applicability of RCBS in various cultural and national groups ( Byeon et al., 2017 ; Horváth et al., 2013 ; Leite et al., 2013 ; Maraz et al., 2015 ; Ridgway et al., 2008 ). RCBS and RCBS-TC are useful epidemiological instruments for examining the prevalence of CBB.…”

“…The cut-off validity was confirmed using the actual purchase data of online shoppers. Since then, RCBS has been translated to five (or more) languages and has been validated in both developed and developing countries ( Byeon et al., 2017 ; He, Kukar-Kinney, & Ridgway, 2018 ; Horváth, van Herk, & Adigüzel, 2013 ; Leite et al., 2013 ; Maraz et al., 2015 ).…”

The Association of Problematic Internet Shopping with Dissociation among South Korean Internet Users

“…Investigators classified the participants into two groups (i.e., PIS and NPIS) based on their RCBS score. Byeon et al [48] suggested that a score of 25 points or higher on the Korean version of the RCBS indicates a problematic shopper. We classified those whose RCBS score was 25 or more as the PIS group.…”

Prevalence of Attention Deficit Hyperactivity Disorder in Girls With Central Precocious Puberty

“…Attention-Deficit Hyperactivity Disorder Rating Scale (ADHD-RS) is 18-item questionnaire completed by the teacher or the parent to help diagnose ADHD. In this study, we used the well-validated Korean version of ADHD-RS administered by parents (So et al, 2002). There are 9 items reflecting symptoms of inattention and 9 items reflecting symptoms of hyperactivity and impulsivity.…”
