Abstract

Objective This study aimed to evaluate the reliability and validity of the Korean version of the Pornography Craving Questionnaire (K-PCQ) using classical test theory and item response theory. Methods The goodness of fit test and differential item functioning (DIF) analysis based on the Rasch model, confirmatory factor analysis (CFA), exploratory factor analysis (EFA), and correlation analysis were used to test its reliability and validity. Results Response data from 226 students were analyzed. According to the goodness of fit test, the outfit mean square value of only one item, Item 11, was greater than 2. The CFA results revealed that all items of the K-PCQ measured a single construct. The EFA results revealed that the K-PCQ had excellent internal reliability. The DIF analysis results showed that the measurement of pornography craving using the K-PCQ did not differ based on gender. The result of Poly-DIMTEST supported the unidimensionality of the K-PCQ. The cutoff value of pornography craving was suggested as a measure of-0.0908 which corresponds to 46 (54.8%) out of a maximum score of 84. Conclusion The items of the K-PCQ are unidimensional and have good reliability and validity. The K-PCQ will be useful in clinical prac-tice and research as a screening tool for pornography craving.
