Progress feedback is an intervention aimed at enhancing patient outcomes in routine clinical practice. This study reports a comprehensive multilevel meta-analysis on the effectiveness of progress feedback in psychological treatments in curative care. The short- and long-term effects of feedback on symptom reduction were investigated using 58 (randomized and non-randomized) studies, analyzing 110 effect sizes in a total of 21,699 patients. Effects of feedback on dropout rate, percentage of deteriorated cases, and treatment duration were also examined. Moderation analyses were conducted for study and feedback characteristics. A small significant effect of progress feedback on symptom reduction (d = 0.15, 95% CI: [0.10, 0.20]) was found, compared to control groups. This was also true for not-on-track cases (d = 0.17, 95% CI: [0.11, 0.22]). In addition, feedback had a small favorable effect on dropout rates (OR = 1.19, 95% CI: [1.03, 1.38]). The moderation analyses identified several potentially interesting variables for further research, including feedback instrument, outcome instrument, type of feedback, feedback frequency, treatment intensity, and country in which the study was conducted. Future studies should report on these variables more consistently so that we can obtain a better understanding of when and why feedback improves outcomes.

进展反馈是一种干预措施，旨在提高常规临床实践中的患者结果。本研究报告了一项关于治疗性护理心理治疗进展反馈有效性的综合多层次荟萃分析。使用 58 项（随机和非随机）研究调查了反馈对症状减轻的短期和长期影响，分析了总共 21,699 名患者的 110 个效应量。还检查了反馈对辍学率、恶化病例百分比和治疗持续时间的影响。对研究和反馈特征进行了适度分析。 与对照组相比，发现进展反馈对症状减轻的微小显着影响（d = 0.15，95% CI：[0.10，0.20]）。对于不在轨道上的情况也是如此（d  = 0.17, 95% CI: [0.11, 0.22])。此外，反馈对辍学率有很小的有利影响（OR  = 1.19, 95% CI: [1.03, 1.38]）。适度分析确定了几个潜在的有趣变量以供进一步研究，包括反馈工具、结果工具、反馈类型、反馈频率、治疗强度和进行研究的国家。未来的研究应该更一致地报告这些变量，以便我们能够更好地了解反馈何时以及为什么会改善结果。
