Recent theories hypothesize that the impulsivity observed in addictive behaviors is a two-factor construct, consisting of Rash Impulsiveness and Reward Sensitivity. There is some evidence for this distinction, but it is unknown what the clinical relevance of this distinction is. The present study examines the predictive value of the two-factor model regarding drop-out from treatment and relapse into substance use in a clinical population of male substance dependent patients. Both behavioral and self-report measures of Rash Impulsiveness and Reward Sensitivity were measured during treatment while substance use relapse was measured after 90days. Results indicate that treatment drop-out could be predicted by a behavioral index of Reward Sensitivity (Card Playing Task); self-reported Rash Impulsiveness only approached significance as predictor drop-out. In contrast, relapse could not be predicted in the present study. These findings might have implications for the early identification and treatment of patients at risk of treatment drop-out.
近期理论假设，成瘾行为中观察到的冲动性是一种双因素结构，由鲁莽冲动和奖励敏感性组成。有一些证据支持这种区分，但这种区分的临床相关性尚不清楚。本研究考察了双因素模型对于男性物质依赖患者临床群体中治疗脱落和物质使用复发的预测价值。在治疗期间测量了鲁莽冲动和奖励敏感性的行为及自我报告指标，而物质使用复发则在90天后进行测量。结果表明，奖励敏感性的行为指标（玩牌任务）可以预测治疗脱落；自我报告的鲁莽冲动仅接近作为预测治疗脱落的显著水平。相比之下，本研究中无法预测复发。这些发现可能对早期识别和治疗有治疗脱落风险的患者具有启示意义。
