Background: The ICD-11 diagnosis of Gaming Disorder (GD) requires the presence of impaired control over gaming, increasing priority over other activities, continued gaming despite adverse consequences, and demonstrable impairment. Tolerance and withdrawal, which are characteristic features of substance dependence, are not accepted as diagnostic features; instead they are noted as "additional clinical features". This study, part of IGS22, sought to examine whether tolerance and dependence are integral components of GD. Method: Data were from 803 participants (age <=65) in the IGS22. There were 76 items in the study measuring impaired control over gaming, increasing priority over other activities, continued gaming despite adverse consequences, e impairment, and tolerance and withdrawal. Results: Tolerance was reported by 32%, and withdrawal by 33.5%, compared with 33.7% reporting impaired control. Exploratory factor analysis (EFA) shows that both tolerance and withdrawal loaded on the same factor as impaired control. Increasing priority loaded on to a second factor and impairment on to a third. We then conducted two sets of confirmatory factor analysis, one with the 3-factor structure identified in the EFA and one with 6-factor with impaired control, tolerance and withdrawal loaded on separate factors. The 3-factor model fitted the data well (CFI=0.962, RMSEA=0.025); with substantially increased model complexity, the 6-factor model only marginally fitted the data better (CFI=0.973, RMSEA= 0.022). Conclusions: The constructs of tolerance and withdrawal largely overlap with impaired control. While they could be additional clinical features, they are unlikely to be necessary for diagnosis and screening for gaming disorder. [ABSTRACT FROM AUTHOR]
