Due to the rising concern of problem video gaming, the DSM-5 has suggested including Internet Gaming Disorder (IGD) as a possible new behavioral addiction and proposed nine criteria to assess IGD. In response, a number of measurement instruments have been developed based on the DSM-5 IGD criteria. This presentation will discuss results from a systematic review that evaluated psychometric properties of these measures. Systematic search identified 22 measures. Meta-analysis revealed that 3.1% of the general population and 6.4% of video gamers had IGD. The estimated prevalence rates largely varied across different measures. Although many measures demonstrated satisfactory structural and construct validities, these measures accounted for an average \u3c 50% of the variance of the items. This suggests that measures do not fully operationalize the DSM-5 criteria and other symptoms should be considered. Measurement invariance and test-retest reliability were established for \u3c 50% of these measures. Diagnostic performance were only examined for two measures using data from clinical structured interviews. While much more work is needed to accurately conceptualize and measure IGD, the present review indicates that the Internet Gaming Disorder Scale – Short Form is the most optimal DSM-5 measure of IGD currently available.
Implications: This work is conducted in response to the call for rigorous research on Internet gaming disorder (IGD). Findings have important implications for implementing uniform, psychometrically sound measures that accurately conceptualize, assess, and identify IGD in both research and clinical settings
