Compulsive sexual behavior disorder (CSBD) is now included as an impulse control disorder in the International Classification of Diseases 11th Revision (ICD-11). CSBD-related problems require global attention as they are not limited to a particular ethnic group or culture. The majority of prior studies have been conducted in western societies. As a first step towards stimulating CSBD research in Korea, we translated and validated CSBD-19, a recently developed screening measure of CSBD, into Korean. The subjects were 404 adults (179 men and 225 women) ranging in age from 19 to 69 years old (mean age=45.01, standard deviation=13.54). The results of confirmatory factor analysis indicated that a five-factor (control, salience, relapse, dissatisfaction, negative consequences) model proposed in a previous study was fit for the current data. Internal consistency coefficient of the Korean version of CSBD-19 (K-CSBD-19) were also good (total items=.938, sub-domains=.712~.898). The results of concurrent validity analysis showed that K-CSBD-19 was positively correlated with the existing scales of related variables. Next, latent profile analysis and receiver operating characteristic analysis were conducted to calculate cut-off points for classifying individuals at high risk of CSBD. We identified a high-risk group of 3.7 percent of the total samples, and a score of 48.5 was proposed as an optimal cut-off point. Lastly, theoretical and practical implications as well as the limitations of this study were discussed.
