Evaluation of the Psychometric Properties of DSM-5 Internet Gaming Disorder Measures: A COSMIN Systematic Review and Meta-Analysis

This review evaluated psychometric properties of measures developed based on the proposed DSM-5 criteria for Internet Gaming Disorder (IGD) and investigated the prevalence of IGD via meta-analyses. Systematic searches in five databases identified 22 measures, examined in 56 pertinent studies. These measures, which seek to operationalize the same DSM-5 criteria, use different wording and highlight different elements of the criteria. Most of the measures demonstrated satisfactory structural and construct validity with high internal consistencies. However, measurement invariance, criterion validity, and test-retest reliability were established for ,50% of the measures. Meta-analysis revealed that 3.1% of the general population and 6.4% of those who play video games have IGD. A unified and comprehensive IGD instrument will benefit research and clinical practice.
