The co-existence of gaming disorder (GD) with other mental health problems has been widely reported. Despite the growing research interest in the comorbidity of GD with attention-deficit/hyperactivity disorder (ADHD), to date, no quantitative synthesis has been performed. The present study comprised a systematic literature search using Scopus, Science Direct, Web of Science, and PubMed databases. Three types of studies were included in the analyses: studies reporting (i) correlation coefficients between the symptoms of GD and ADHD, (ii) means, and standard deviations for comparison of GD severity between ADHD/non-ADHD individuals, and (iii) comparison of ADHD severity between GD/non-GD individuals. The results indicated a moderate relationship between GD and ADHD symptom severity when both subdomains of ADHD were combined (r = 0.296), and also when only inattention (r = 0.306) or hyperactivity (r = 0.266) symptoms were analyzed, which was also confirmed in a structural equation model meta-analysis. Studies showed a large average difference comparing the GD symptom severity of ADHD and non-ADHD individuals (g = 0.693), or ADHD symptom severity of GD and non-GD individuals (g = 0.854). In some cases, higher estimates of association were reported among studies that (i) had a higher proportion of males, (ii) assessed problematic internet use among predominantly videogame player samples rather than assessing only GD, and (iii) had been more recently published. The present review shows that this is an emerging field demonstrating significant results in cross-sectional correlational studies. However, future research should apply more rigorous methodologies to investigate the relationship further (e.g., longitudinal studies and studies using professional/clinical ratings and diagnosis). These results suggest that screening and treatment for ADHD among individuals with gaming disorder is necessary, and individuals with ADHD should be made aware of their higher susceptibility to gaming disorder.

游戏障碍（GD）与其他心理健康问题共存已被广泛报道。尽管人们对 GD 与注意力缺陷/多动障碍 (ADHD) 合并症的研究兴趣日益浓厚，但迄今为止，尚未进行定量综合。本研究包括使用Scopus、Science Direct、Web of Science和PubMed数据库进行系统文献检索。分析中纳入了三种类型的研究：研究报告 (i) GD 和 ADHD 症状之间的相关系数，(ii) ADHD 与非 ADHD 个体之间 GD 严重程度比较的平均值和标准差，以及 (iii) GD/非 GD 个体之间 ADHD 严重程度的比较。结果表明，当 ADHD 的两个子域合并时（r  = 0.296），以及仅分析注意力不集中（r  = 0.306）或多动症（r  = 0.266）症状时，GD 和 ADHD 症状严重程度之间存在中度相关性，这也得到了证实在结构方程模型荟萃分析中。研究表明，比较 ADHD 和非 ADHD 个体的 GD 症状严重程度 ( g  = 0.693)，或者 GD 和非 GD 个体的 ADHD 症状严重程度 ( g  = 0.854) 存在很大的平均差异。在某些情况下，在以下研究中报告了更高的关联估计：(i) 男性比例较高，(ii) 评估主要是视频游戏玩家样本中存在问题的互联网使用情况，而不是仅评估 GD，以及 (iii) 最近发表。本综述表明，这是一个新兴领域，在横断面相关研究中取得了显着成果。然而，未来的研究应该应用更严格的方法来进一步研究这种关系（例如，纵向研究和使用专业/临床评级和诊断的研究）。这些结果表明，对游戏障碍患者进行 ADHD 筛查和治疗是必要的，并且应让 ADHD 患者意识到他们对游戏障碍的易感性较高。
