The second sample data was collected from 132 people in the game disorder subclinical group. In both samples, a single-factor model best explained the data. A total of 9 questions were finally selected among the main questions, and the questions showed high factor loadings and reliability. In addition, as a result of evaluating validity through correlation analysis with factors related to gaming disorder, all showed excellent official validity and convergent validity. As a result of the ROC analysis, the total score was determined as 10 points for the criteria for the classification of game disorder risk groups in the finalized selection tool.
