Participants in randomized control trials (RCTs) should be representative of those most likely to experience the disorder of focus, yet reviews of psychology research studies consistently find certain demographic groups are overrepresented at the price of others being unincluded. The present review aimed to characterize the demographic representation of US-based RCTs for gambling disorder and compare findings to the population of individuals most likely to experience the disorder. Thirteen US-based RCTs comprising a total of 2,343 participants were reviewed. We found that although gambling disorder is most prevalent among low SES racial minorities, RCTs are mostly conducted among populations who are white, employed, and have some level of college education. Demographic variables that are related to the likelihood of experiencing gambling disorder are not consistently reported, and there are many groups of individuals who experience gambling disorder that have been virtually left out of all treatment study samples to date. We conclude with recommendations for future gambling focused treatment studies, which are geared towards increasing the convergence between characteristics of participants in RCTs and those who experience gambling disorder in the United States.

随机对照试验 (RCT) 的参与者应该代表那些最有可能出现注意力障碍的人，但对心理学研究的评论一致发现，某些人口群体的人数过多，而其他人则被排除在外。本综述旨在描述基于美国的赌博障碍随机对照试验的人口统计学特征，并将结果与​​最有可能出现这种障碍的人群进行比较。审查了 13 项基于美国的随机对照试验，共有 2,343 名参与者。我们发现，尽管赌博障碍在低 SES 少数族裔中最为普遍，但 RCT 主要在白人、就业和具有一定程度大学教育水平的人群中进行。与患赌博障碍的可能性相关的人口统计学变量并未得到一致报告，并且迄今为止，有许多患有赌博障碍的个体实际上已被排除在所有治疗研究样本之外。我们总结了对未来以赌博为重点的治疗研究的建议，这些研究旨在增加 RCT 参与者的特征与美国经历赌博障碍的人的特征之间的趋同。
