Prize-based contingency management (CM) is efficacious in treating cocaine abuse, and the chance-based procedures of prize CM may be appealing to those who gamble. Using data from three randomized trials, we evaluated whether cocaine-abusing patients who had wagered in the month before treatment (n = 62) responded more favorably to prize CM than those who had not (n = 278). Participants were randomized to standard care (SC) or SC plus prize CM. Although prize CM was related to better outcomes overall, recent gambling was not associated with outcomes across or within treatment conditions. Gambling participation before treatment entry was associated with reductions in gambling over time, and this effect was more pronounced among those assigned to CM. These data suggest that prize CM is equally efficacious for substance-abusing patients who do and do not gamble, and they extend prior studies indicating that prize CM does not increase gambling.
基于奖励的随机对照试验（CM）对治疗可卡因滥用有效，而 CM 的随机奖励程序可能对那些有赌博倾向的人有吸引力。本研究使用三项随机试验的数据，评估了在治疗前一个月有过赌博行为（n = 62）的可卡因滥用患者是否比没有赌博行为的患者（n = 278）对基于奖励的 CM 治疗反应更好。参与者被随机分配到标准护理（SC）或 SC 加基于奖励的 CM。尽管基于奖励的 CM 总体上与更好的结果相关，但最近的赌博与治疗条件内或跨治疗条件的结果无关。治疗前的赌博参与与随时间的减少有关，而在被分配到 CM 的人群中，这种效果更为明显。这些数据表明，基于奖励的 CM 对有赌博和不赌博的物质滥用患者同样有效，并扩展了先前的研究，表明基于奖励的 CM 不会增加赌博。
