OBJECTIVE Some psychotherapists are more effective than others, which means that patients' treatment outcomes partly depend on therapist effects (TEs). This study investigated whether the use of progress feedback influences TE. METHOD Data from N = 4,549 participants and 131 therapists across six clinical trials of progress feedback were analyzed. All trials used the Outcome-Questionnaire-45 (OQ-45) outcome measure and assigned psychotherapy patients to a usual psychological care condition or feedback condition. We examined whether feedback utilization moderated TE using multilevel modeling and random-effects meta-analysis. RESULTS TE explained a small proportion (intracluster correlation coefficient [ICC] = .011) of variability in posttreatment OQ-45 scores in the pooled multistudy sample, after controlling for intake severity. Feedback utilization was associated with a statistically significant reduction of the magnitude of the TE (ICC = .009) by approximately 18.2%. Secondary analyses of OQ-45 subscales indicated that TEs were statistically significant in relation to symptom distress, but not interpersonal relations or social role. Feedback was associated with better treatment outcomes and narrower variability between therapists. CONCLUSIONS Feedback-informed treatment reduces the gap between more and less effective therapists, leading to more equitable and effective psychological care.

进度反馈缩小了越来越有效的治疗师之间的差距：治疗师对临床试验的影响荟萃分析。

目标一些心理治疗师比其他治疗师更有效，这意味着患者的治疗结果部分取决于治疗师效果（TEs）。本研究调查了使用进度反馈是否会影响 TE。方法 对来自 N = 4,549 名参与者和 131 名治疗师的数据进行了分析，这些数据来自六项进展反馈临床试验。所有试验都使用 Outcome-Questionnaire-45 (OQ-45) 结果测量，并将心理治疗患者分配到通常的心理护理条件或反馈条件。我们使用多级建模和随机效应荟萃分析检查了反馈利用是否缓和了 TE。结果 TE 解释了在控制摄入严重程度后，合并的多研究样本中治疗后 OQ-45 评分的一小部分变异（组内相关系数 [ICC] = .011）。反馈利用与 TE (ICC = .009) 幅度的统计显着降低有关，大约 18.2%。对 OQ-45 分量表的二次分析表明，TE 与症状困扰有关，但与人际关系或社会角色无关。反馈与更好的治疗结果和治疗师之间更窄的变异性有关。结论 以反馈为依据的治疗减少了更多和更少有效治疗师之间的差距，从而导致更公平和有效的心理护理。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。对 OQ-45 分量表的二次分析表明，TE 与症状困扰有关，但与人际关系或社会角色无关。反馈与更好的治疗结果和治疗师之间更窄的变异性有关。结论 以反馈为依据的治疗减少了更多和更少有效治疗师之间的差距，从而导致更公平和有效的心理护理。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。对 OQ-45 分量表的二次分析表明，TE 与症状困扰有关，但与人际关系或社会角色无关。反馈与更好的治疗结果和治疗师之间更窄的变异性有关。结论 以反馈为依据的治疗减少了更多和更少有效治疗师之间的差距，从而导致更公平和有效的心理护理。（PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
