The present study compares the impact of individualized treatment provided by trainee therapists based on a traditional cognitive behavior therapy (CBT) and acceptance and commitment therapy (ACT) model. Fourteen therapists were given initial training in CBT and ACT. Outpatients (N = 28) were randomized to either approach, with each therapist treating one client within each model, linked to a functional analysis. Clients treated within an ACT model showed better symptom improvement than the CBT clients, despite the fact that students felt initially less knowledgeable about ACT and were more fearful throughout when it was used. CBT improved client self-confidence more rapidly than ACT, and ACT improved acceptance more than CBT. Both processes predicted better outcomes; acceptance remained predictive when controlling for self-confidence but not vice versa. Overall, therapists with limited training in both models got better results with ACT and the processes of change fit with the ACT model.
本研究比较了实习治疗师基于传统认知行为疗法（CBT）和接纳与承诺疗法（ACT）模型提供的个体化治疗的影响。14名治疗师接受了CBT和ACT的初始培训。门诊患者（N = 28）被随机分配到两种治疗方法中的一种，每位治疗师在每种模型下治疗一名患者，并与功能分析相关联。尽管学生们最初觉得对ACT了解较少，并且在使用ACT时始终更担心，但接受ACT模型治疗的患者比接受CBT治疗的患者症状改善得更好。CBT比ACT更快地提高了患者的自信心，而ACT比CBT更能提高接纳程度。这两个过程都预示着更好的治疗效果；在控制自信心时，接纳程度仍然具有预测性，但反之则不然。总体而言，在这两种模型方面接受有限培训的治疗师使用ACT取得了更好的效果，并且改变过程符合ACT模型。
