- Abstract
- The aim of this study was to develop a screening questionnaire to distinguish high-risk individuals associated with game overuse from casual internet users. Reliability, validity, and diagnostic ability were evaluated for the newly developed Game Overuse Screening Questionnaire (GOS-Q). Preliminary items were assessed by 50 addiction experts online and 30 questions were selected. A total of 158 subjects recruited from six community centers for internet addiction participated in this study. Finally, 150 people were used in the analysis after excluding eight non-respondents. GOS-Q, Young's internet addiction scale, and Korean scale for internet addiction were used to assess concurrent validity. Internal consistency and item-total correlations were favorable (a= 0.96, r= 0.47-0.82). Test-retest reliability was moderate in size (r= 0.74). GOS-Q showed superior concurrent validity, and the highest correlation with Y-Scale (r= 0.77). The construct validity was marginally supported by a six-factor model using exploratory factor analysis. The area under the Receiver Operating Characteristic curve was 0.945. The high-risk addiction group was effectively characterized by a cut-off point of 38.5, with a sensitivity of 0.87 and a specificity of 0.88. Overall, the current study supports the use of GOS-Q as a reliable screening tool in a variety of settings.
