High rates of relapse following treatment have compelled researchers to elucidate the individual difference factors that change among those who receive substance abuse treatment. Previous research has suggested that trait-disinhibition variables may be of particular relevance. Given that these variables are primarily considered to be trait-level factors, the extent to which they are malleable by treatment is an important consideration. Thus, the purpose of this study was to examine the effect of a residential substance abuse treatment program on specific trait-disinhibition variables (e.g., risk-taking, impulsivity). A sample of 81 inner-city substance users were assessed on self-report and behavioral indicators of trait-disinhibition over a 30-day course of treatment. Risk-taking propensity was found to significantly decrease from pre- to post-treatment. Results are discussed with respect to implications for better understanding the factors that may operate as mechanisms of change during treatment, thereby having the potential to inform substance abuse prevention and treatment programs.
治疗后复发率居高不下，促使研究人员去阐明接受药物滥用治疗的人群中会发生变化的个体差异因素。先前的研究表明，特质去抑制变量可能尤为相关。鉴于这些变量主要被视为特质水平的因素，它们在治疗中可塑的程度是一个重要的考量。因此，本研究的目的是检验一个住院药物滥用治疗项目对特定特质去抑制变量（如冒险、冲动）的影响。对81名市中心区药物使用者样本在为期30天的治疗过程中进行了特质去抑制的自我报告和行为指标评估。发现冒险倾向从治疗前到治疗后显著降低。讨论了这些结果对于更好地理解可能作为治疗期间变化机制的因素的意义，从而有可能为药物滥用预防和治疗项目提供信息。
