A systematic review on the intersection of attention-deficit hyperactivity disorder and gaming disorder.

INTRODUCTION

Studies of Gaming Disorder (GD) consistently identify co-morbidity with various psychiatric disorders including major depression, obsessive compulsive disorder and anxiety disorders. One of the strongest associations has been with Attention Deficit Hyperactivity Disorder (ADHD). We present a systematic review of this association by pooling and integrating available evidence.

METHODS

PubMed, EMBASE, PsychInfo and CINHAHL were searched for articles that reported a quantitative association between GD and ADHD and its dimensions, using equivalent search terms. Quality appraisal was done using criteria adapted from the Critical Appraisal Skills Package (CASP) checklists.

RESULTS

1028 articles were identified, of which 29 studies were included for systematic review (n = 56650 participants). Most of these studies were observational in nature, and were of moderate quality, with deficits particularly in the domains of generalisability and confounding. Community surveys (n = 18) of purposive samples constituted the majority, with fewer clinic-based samples (n = 11). While ADHD symptoms were consistently associated with GD, More frequent associations were displayed with inattention associations with GD than other ADHD subscales. There were no conclusive findings regarding the type of game on severity of either condition, or on completion of treatment.

CONCLUSIONS

The findings suggest an association between ADHD and GD, although the direction of the relationship is unclear. This has implications for clinical practice, policy and research. We recommend that ADHD is screened for when evaluating IGD as part of routine practice."
