OBJECTIVE Previous studies have shown that feedback-informed treatment can improve outcomes of psychological treatments. This randomized controlled effectiveness trial evaluated the effect of progress feedback on treatment duration, symptom reduction, and dropout in individual cognitive behavioral therapies (CBTs). A control condition where CBT was combined with low-intensive monitoring of progress was compared to an experimental condition where CBT was combined with a high-intensive form of feedback. METHOD Data of 368 outpatients (57.9% female, mean age 41.4 years, SD = 12.2) in secondary care were analyzed using multilevel analyses. Treatment duration was assessed with the number of sessions clients received. Symptom reduction was measured with the Symptom Checklist Revised. Possible moderators of the effect of intensive progress feedback on outcome were explored. RESULTS Clients achieved the same amount of symptom reduction in significantly fewer sessions in the high-intensive feedback condition. Additionally, dropout was significantly lower in the high-intensive feedback condition. Post hoc analyses assessing clients' diagnoses as a possible moderator showed that clients with personality disorders (mainly Cluster C) achieved more symptom reduction in fewer sessions when high-intensity feedback was provided. Also, a high degree of implementation within the experimental condition was associated with fewer treatment sessions. CONCLUSION In sum, the use of high-intensive client feedback reduced treatment duration and reduced dropout of CBT. Thus, feedback-informed CBTs seem to be a promising adaptation of conventional CBT.

反馈知情的认知行为疗法对治疗结果的影响：一项随机对照试验。

目的先前的研究表明，反馈知情治疗可以改善心理治疗的效果。该随机对照有效性试验评估了进展反馈对个体认知行为疗法（CBT）的治疗持续时间，症状减轻和退学的影响。将CBT与低强度进度监测相结合的对照条件与CBT与高强度反馈形式相结合的实验条件进行了比较。方法采用多级分析方法分析了368例二级保健门诊患者（女性57.9％，平均年龄41.4岁，SD = 12.2）的数据。根据接受治疗的患者数评估治疗时间。通过修订症状清单来测量症状减轻。探索了可能的主持人对进度进行深入反馈对结果的影响。结果在高强度反馈条件下，客户通过更少的会话次数获得了相同程度的症状减轻。此外，在高强度反馈条件下，辍学率明显降低。事后分析评估客户的诊断为可能的主持人，结果显示，在提供高强度反馈的情况下，人格障碍（主要是C组）的客户在更少的会话中实现了更多的症状减轻。同样，在实验条件下的高度实施与更少的治疗时间相关。结论总而言之，高强度客户反馈的使用减少了治疗时间并减少了CBT的辍学。从而，反馈知情的CBT似乎是对传统CBT的有希望的改编。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
