Abstract
Objective Video Game Dependency Scale (VGDS) evaluates degrees of online and offline gaming disorder. In this study, we examined the average reliability of VGDS scores and whether they provide values that justify their use, characterized the variation in reliability estimates across studies, and identified study characteristics that explain heterogeneity in reliability estimates. Method A reliability generalization meta-analysis based on the REGEMA guidelines was conducted. From the 19 selected articles that applied VGDS, 14 (16 independent samples) reported 17 reliability estimates (16 alpha coefficients and 1 test-retest reliability coefficient). A random-effects model was applied in the statistical analyses. Results The average reliability of the total VGDS scores assessed as internal consistency by Cronbach’s alpha coefficient was 0.925 (95% CI [.901,.942]). The results also found these coefficients to be significantly heterogeneous. Conclusions According to the psychometric theory, VGDS scores can be considered reliable for exploring gaming disorder in field research and clinical practice. Significance statement This study provides evidence for the score reliability of the VGDS, a relevant tool for assessing Internet gaming disorder. It highlights the importance of addressing score reliability and advancing measurement and assessment in practice and research fields.
