Readers should be aware the published meta-analysis included two studies (Vadlin et al., 2016, 2018) that should have been excluded. Dr Sophia Vadlin, the corresponding author of these two studies, informed us that, in these two studies, the Gaming Addiction Identification Test (GAIT) was used to measure problematic gaming (as indicated by endorsement of gaming disorder [GD] symptoms) but did not assess GD per se due to employing a data-driven (percentile) scoring approach and not a standard 5/9 cut-off approach. A third study by Dr Vadlin (i.e. Vadlin et al., 2015) also employed the GAIT but adhered to the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) recommendations for measuring GD, and therefore was correctly included. To rectify this issue, we have reconducted the meta-analysis with these two studies excluded, which has resulted in some slight adjustments.
Excluding the two studies by Vadlin and colleagues, the updated overall prevalence rate is 2.96%, reduced from the original 3.05%. The updated gender analysis indicated that males were 2.3 times more likely to report GD, as compared to the original figure of 2.5.
Additional minor corrections of note are study region accounted for 20.4% of the variance in GD prevalence (original: 12.3%) and year of publication explained 14.5% of the variance in GD prevalence (original: 16.5%). In terms of moderator analysis, all variables retained their original significance level; however, sample size was no longer significant in the multivariate model. All three manuscript tables have been updated to reflect these revisions and are available as Supplementary Material.
