Accommodation of obsessive compulsive disorder (OCD) symptoms by family members is common. This paper presents a systematic meta-analytic review on family accommodation and OCD symptom severity. Fourteen studies investigating the relationship between family accommodation and OCD symptoms were selected. The medium effect size of the relationship between family accommodation and OCD symptom severity was significant (r = .35; 95% CI: .23 to .47), based on a Hunter-Schmidt random effects model with a total of 849 participants. Although there was some evidence of publication bias, Rosenthal's fail-safe N suggested that 596 studies with zero effect would be needed to reduce the mean effect size to non-significant. Findings are discussed in the context of the limitations of the studies, and in particular the reliance on cross-sectional designs which impede causal conclusions. Future research to evaluate a family accommodation intervention in a randomized controlled design and using mediation analysis to explore change mechanisms is called for.
家庭成员对强迫症（OCD）症状的适应是常见的。本文对家庭适应和 OCD 症状严重程度进行了系统的元分析综述。选择了 14 项研究来调查家庭适应与 OCD 症状之间的关系。基于 Hunter-Schmidt 随机效应模型，对共有 849 名参与者的研究结果进行分析，家庭适应与 OCD 症状严重程度之间的中等效应大小(r =.35; 95% CI:.23 to.47)具有统计学意义。尽管存在一些出版偏倚的证据，但 Rosenthal 的失效安全 N 表明，需要 596 项零效应的研究才能将平均效应大小降低到非显著水平。研究结果在研究的局限性背景下进行了讨论，特别是依赖于妨碍因果结论的横断面设计。需要进行一项家庭适应干预的随机对照设计的未来研究，并使用中介分析来探索变化机制。
