OBJECTIVE There is little evidence-based knowledge of how psychotherapists should handle both sudden gains and more gradual session-by-session changes, either in general or in individuals suffering from generalized anxiety disorder. METHODS Using an ABAB crossed-therapist randomized clinical implementation trial design (N = 80 patients and 20 therapists), we contrasted a Prolonged Focus on Change (PFC, N = 40) implementation with a State-Of-The-Art (SOTA, N = 40) implementation. Both implementations were based on a widely used cognitive behavioral therapy approach (Mastery of your Anxiety and Worry package) with the only difference that in the PFC implementation, the therapists were instructed to systematically explore eventual changes at the beginning of the therapy sessions. RESULTS Based on a 3-level hierarchical linear model, PFC implementation showed faster symptom reduction in worry over therapy (i.e., linear change) and a decelerated (quadratic) change until 12-month follow-up in comparison to the SOTA implementation. CONCLUSION These findings provide clinically useful information about potential short-term and long-term effects of exploring occurring change in GAD populations. Randomized clinical implementation trial designs are a step forward allowing to experimentally investigate basic psychotherapeutic strategies in process-based psychotherapy.

探索广泛性焦虑症认知行为疗法的变化——一项双臂 ABAB 交叉治疗师随机临床实施试验。

目标 关于心理治疗师应该如何处理突然的收益和更渐进的逐个会话的变化,无论是一般情况下还是在患有广泛性焦虑症的个体中,几乎没有循证知识。方法 使用 ABAB 交叉治疗师随机临床实施试验设计(N = 80 名患者和 20 名治疗师),我们将长期关注变革(PFC,N = 40)实施与最先进的(SOTA,N = 40) 实施。两种实施都基于广泛使用的认知行为治疗方法(掌握你的焦虑和担忧包),唯一的区别是在 PFC 实施中,治疗师被指示在治疗开始时系统地探索最终的变化。结果 基于 3 级分层线性模型,与 SOTA 实施相比,PFC 实施显示对治疗的担忧(即线性变化)和减速(二次)变化的症状减少更快,直到 12 个月的随访。结论 这些发现提供了关于探索 GAD 人群中发生的变化的潜在短期和长期影响的临床有用信息。随机临床实施试验设计是向前迈出的一步,允许在基于过程的心理治疗中对基本心理治疗策略进行实验研究。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。结论 这些发现提供了关于探索 GAD 人群中发生的变化的潜在短期和长期影响的临床有用信息。随机临床实施试验设计向前迈进了一步,允许在基于过程的心理治疗中对基本心理治疗策略进行实验研究。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。结论 这些发现提供了关于探索 GAD 人群中发生的变化的潜在短期和长期影响的临床有用信息。随机临床实施试验设计向前迈进了一步,允许在基于过程的心理治疗中对基本心理治疗策略进行实验研究。(PsycInfo 数据库记录 (c) 2021 APA,保留所有权利)。
