摘要:Objective: this study aimed to explore the effect of acceptance commitment therapy (ACT) on Obsessive compulsive disorder (OCD). Methods: randomized controlled trials of the effect of ACT on obsessive-compulsive disorder were searched in the Cochrane Library, PubMed, Web of Science, EMBASE and Google Scholar databases, and the measurement data of the Yale-Brown Obsessive Scale(Y-BOCS) test scores were meta-analyzed using Revman5.3 software. Results: The study included 5 eligible literatures, with a total sample of 275 persons. The results of meta-analysis on the effect of ACT alone showed that ACT had a better effect on OCD than other treatment methods (MD = -3.76, Z = 4.41, P≤0.05). Meta-analysis results of ACT combined SSRIs therapy showed that ACT combined therapy was better than SSRIs alone (MD = - 7.18, Z =6.59, P ≤ 0.05). Conclusion: acceptance commitment therapy can effectively treat OCD.
