BACKGROUND Parent-Child Interaction Therapy (PCIT) is a well-established treatment for behavioural, hyperactivity and oppositional-defiant problems in children. Previous meta-analyses are scarce, and they have tended to mix problems and measures. OBJECTIVE A meta-analysis study was conducted with all available studies on PCIT (1980 to 2020) to determine its specific efficacy and effectiveness for child behavioural problems. METHOD Selection from databases collected a total of 100 studies. The inclusion criteria were to compare PCIT in children with behavioural problems between 2 and 12 years of age; comparing groups and using standardized instruments. RESULTS PCIT exhibited a significant mean effect size ( d = -0.87 [95% CI: -1.10, -0.63] versus control and/or treatment-as-usual groups, but the effect size was smaller and not significant in follow-ups ( d = -0.23 [95% CI: -0.49, 0.04]). The within-group studies, comparing versions of PCIT, also demonstrated a significant effect size ( d = -0.26 (95% CI: -0.43, -0.08), and in pre-post comparisons this effect was greater ( d = -1.40 [95% CI: -1.69, -1.10]). CONCLUSIONS PCIT is an effective intervention for treating child behaviour problems such as disruptive, hyperactive, negative, and externalizing problems. It is supported by 40 years of experimental and clinical studies, and also by this meta-analysis.

亲子互动疗法 (PCIT) 对儿童行为问题的疗效和有效性的荟萃分析。

背景亲子互动疗法(PCIT) 是一种成熟的治疗方法，用于治疗儿童的行为、多动和对立违抗问题。以前的荟萃分析很少，而且它们往往将问题和措施混为一谈。目标 对所有可用的关于 PCIT 的研究（1980 年至 2020 年）进行了一项荟萃分析研究，以确定其对儿童行为问题的具体功效和有效性。方法 从数据库中选择总共收集了 100 项研究。纳入标准是比较有行为问题的 2 至 12 岁儿童的 PCIT；比较组和使用标准化工具。结果 PCIT 表现出显着的平均效应大小 ( d = -0.87 [95% CI: -1.10, -0.63] 与对照组和/或常规治疗组相比，但在随访中效应量较小且不显着（d = -0.23 [95% CI: -0.49, 0.04]）。比较不同版本的 PCIT 的组​​内研究也证明了显着的效应大小 (d = -0.26 (95% CI: -0.43, -0.08)，并且在前后比较中这种效应更大 (d = -1.40 [ 95% CI: -1.69, -1.10]). 结论 PCIT 是治疗儿童行为问题的有效干预措施，如破坏性、多动、消极和外化问题。它得到了 40 年的实验和临床研究的支持，也得到了这个荟萃分析。结论 PCIT 是治疗儿童行为问题（例如破坏性、多动、消极和外化问题）的有效干预措施。它得到了 40 年的实验和临床研究的支持，也得到了这项荟萃分析的支持。结论 PCIT 是治疗儿童行为问题（例如破坏性、多动、消极和外化问题）的有效干预措施。它得到了 40 年的实验和临床研究的支持，也得到了这项荟萃分析的支持。
