Purpose This methodological study established the Turkish validity and reliability of the Gaming Disorder Scale for Adolescents (GADIS-A). Methods The study was conducted with 378 adolescents studying in primary and secondary education institutions in the central districts of a province in Turkey affiliated with the Provincial Directorate of National Education. Data were collected using an adolescent information form and GADIS-A. An ethics committee approved the study, and permission was obtained from the institution. Results Confirmatory Factor Analysis (CFA) showed that the scale had factor loadings of 0.511 to 0.768, the Goodness of Fit indices of >0.87, and the RMSEA index of <0.10. The total scale had a Cronbach's alpha of 0.860. Conclusion The results show that GADIS-A is a valid and reliable measure for the Turkish sample. Implications to practice GADIS-A, a highly valid and reliable scale, can be used as a measurement tool in national and international screening programs.
