Method: In the present study, participants were assessed with the IGDT-10, the nine-item IGD Scale - Short Form (IGDS9-SF), and the Motives for Online Gaming Questionnaire (MOGQ). Results: Confirmatory factor analysis showed that the IGDT-10's one-factor structure (i.e., dimensional structure) was satisfactory. The scale was also reliable (i.e., internally consistent with a Cronbach's alpha of 0.79) and showed adequate convergent and criterion-related validity as shown by positive correlations between average daily time spent playing games over the past year and IGDS9-SF and MOGQ scores. By applying the DSM-5 threshold to diagnose IGD (meeting at least five criteria), the incidence of individuals with IGD was found to be 7.4% (n=56) in the entire sample. Conclusion: These results demonstrate the Turkish version of the IGDT-10 to be a valid and reliable instrument for determining the magnitude of problems associated with IGD among young adults and for early diagnosis of IGD in clinical environments and comparable studies.eninfo:eu-repo/semantics/openAccessE-SportsInternet Gaming DisorderIgdt-10ScaleUniversity StudentsVideo GamingYoung AdultsArticle331192810.14744/DAJPNS.2019.000572-s2.0-85085702892WOS:000526035800003370963N/AQ3
