This study examined the transdiagnostic effect of acceptance and commitment therapy (ACT) on impulsive decision-making in a community sample. A total of 40 adults were randomized to eight individual sessions of ACT or an inactive control. Participants completed pre-, mid-, and post-assessments for psychological symptoms; overall behavior change; valued living; delay discounting; psychological flexibility; and distress tolerance. Data were analyzed with multilevel modeling of growth curves. Significant interaction effects of time and condition were observed for psychological flexibility, distress tolerance, psychological symptoms, and the obstruction subscale of valued living. No significant interaction effect was found for two delay discounting tasks nor the progress subscale of valued living. The ACT condition had a significantly larger reduction of problem behavior at post-assessment. The results support use of ACT as a transdiagnostic treatment for impulsive behaviors. The lack of change in delay discounting contrasts previous research.
本研究考察了接纳与承诺疗法（ACT）对社区样本冲动决策的跨诊断效应。共有 40 名成年人被随机分配到八次个体 ACT 治疗或非活动对照。参与者在心理症状、整体行为改变、有价值的生活、延迟折扣、心理灵活性和痛苦耐受力方面完成了预评估、中期评估和后评估。采用增长曲线的多层次建模对数据进行了分析。在心理灵活性、痛苦耐受力、心理症状和有价值的生活的障碍子量表方面，观察到时间和条件的显著交互效应。在两个延迟折扣任务和有价值的生活的进展子量表方面，没有发现显著的交互效应。ACT 条件在后期评估中对问题行为的减少有显著的影响。结果支持将 ACT 作为一种冲动行为的跨诊断治疗方法。延迟折扣方面没有变化与之前的研究形成对比。
