The purpose of this study is to translate and validate the Problematic Pornography Consumption Scale(PPCS; Bőthe et al., 2017). We analyzed 336 Korean adults. We conducted Confirmatory Factor Analysis to test that the original scale factor structure was applied equally to Korean adults. As a result of the analysis, it was confirmed that it was the same hierarchical secondary structure model as the results of the validation study of the PPCS. Subsequently, the reliability, Concurrent validity, convergent validity of the Korean version of the Problematic Pornography Consumption Scale were verified, and all of them showed appropriate levels of results. We conduct Latent Profile Analysis(LPA) to classify latent groups according to the level of problematic pornography consumption. As a result, it was confirmed that it was appropriate to classify the entire sample into three groups. ROC analysis was conducted to identify the high-risk group, and optimal cut-off point for identifying the high-risk group was confirmed as 67 points. Through the results of this study, it was confirmed that the Korean version of the Problematic Pornography Consumption Scale is reliable and valid scale to measure the problematic pornography consumption level of Korean adults. Finally, implications and limitations of this study and suggestions for future research were discussed.
