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.

探索针对广泛性焦虑症的认知行为疗法的变化-一项两臂ABAB交叉治疗师随机临床实施试验。

目的很少有循证医学的知识表明心理治疗师在一般情况下或在患有广泛性焦虑症的个体中应如何应对突然的收获和逐步的逐步改变。方法采用ABAB交叉治疗师随机临床实施试验设计(N = 80例患者和20位治疗师),我们将长期关注变更(PFC,N = 40)实施与最新技术(SOTA,N = 40)实施。两种实施方式均基于广泛使用的认知行为疗法(掌握焦虑和忧虑软件包),唯一的不同是在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。结果基于三级分层线性模型,与SOTA实施相比,PFC实施显示出更快的症状缓解缓解了对治疗的担忧(即,线性变化)和减缓的(二次)变化,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,可以通过实验研究基于过程的心理治疗中的基本心理治疗策略。(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是向前迈出的一步,可以通过实验研究基于过程的心理治疗中的基本心理治疗策略。(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是向前迈出的一步,可以通过实验研究基于过程的心理治疗中的基本心理治疗策略。(PsycInfo数据库记录(c)2021 APA,保留所有权利)。
