Measurement instruments of online gaming disorder in adolescents and young people according to DSM-5 criteria: a systematic review.

The inclusion of Internet Gaming Disorder (IGD) in the DSM-5 has generated controversy over its diagnosis, and it therefore seems necessary to establish a clear cut-off point to identify when excessive gaming becomes problematic. Such identification is especially difficult in adolescents and young people, who frequently dedicate a great deal of time to online games. The goal of this systematic review was to analyze the instruments developed to assess IGD in adolescents and young people since its inclusion in the DSM-5. We identified 13 studies which included validations of seven assessment instruments for IGD in adolescents and young people. Each instrument and its validations in different languages are described. In comparison to previous reviews, a lower diversity of assessment instruments, a reduction in the number of items and a more uniform form of measurement was observed, maintaining high internal consistency and good criterion validity. However, problems related to sample selection, the lack of sensitivity and specificity studies, and the establishment of cut points and profiles of gamers remain. Advances in the analysis of the psychometric qualities of the instruments and their validation in different countries are needed, and cultural differences should be considered in order to allow the prevalence of this problem to be compared.
