This study aimed to validate the Korean version of the Internet Gaming Disorder Scale (K-IGDS) which consisted of factors examining nine criteria from the DSM-5. A total of 719 adults participated in the online (n=414) and offline (n=305) questionnaire including the Korean Game Addiction Scale for Adults, the Short-form of Problematic Online Gaming Questionnaire, the Brief Symptoms Inventory-18, the Perceived Daily Stress Scale, the Korean Version of the Self-control Scale, and the Korean Version of the Difficulties in Emotion Regulation Scale. Moreover, the Structured Clinical Interview for Internet Gaming Disorder was individually conducted to a subsample of 99 people among the total 719 participants. The results were as follows: 1) Confirmatory factor analyses demonstrated that K-IGDS had a satisfactory construct validity, 2) Correlation analyses showed that K-IGDS had a good convergent validity and concurrent validity, 3) Receiver Operating Characteristic (ROC) analysis showed that the Area Under Curve (AUC) covered 83.0%, suggesting that the K-IGDS was a good tool to diagnose the Internet Gaming Disorder. The cut-off score was proposed and implications and limitations of the study were discussed.
