Although exposure and response prevention (ERP) is an effective treatment for obsessive compulsive disorder (OCD), it is unclear whether the decoupling of obsessions and compulsions is associated with treatment response. Accordingly, the present study examined change in the association between obsessions and compulsions during ERP for OCD as well as the association between decoupling of obsessions and compulsions and treatment outcome. The sample consisted of 140 youths with OCD who received 10 sessions of cognitive behavioral therapy with an emphasis on ERP. The findings show that the correlation and covariance of obsessions and compulsions increased during treatment. However, for participants that did not show improvement, the association between obsessions and compulsions strengthened over the course of treatment. In contrast, the association between obsessions and compulsions weakened over the course of ERP for treatment responders. These findings highlight the importance of the relationship between obsessions and compulsions in the treatment of OCD.

尽管暴露和反应预防（ERP）是强迫症（OCD）的有效治疗方法，但目前尚不清楚强迫症和强迫症的脱钩是否与治疗反应相关。因此，本研究检查了强迫症 ERP 期间强迫观念和强迫行为之间关联的变化，以及强迫观念和强迫行为的脱钩与治疗结果之间的关系。该样本由 140 名强迫症青少年组成，他们接受了 10 次以 ERP 为重点的认知行为疗法。研究结果表明，强迫症和强迫症的相关性和协方差在治疗期间增加。但是，对于没有表现出改善的参与者，痴迷与强迫之间的联系在治疗过程中得到了加强。相比之下，在治疗反应者的ERP过程中，强迫与强迫之间的联系减弱了。这些发现强调了强迫症治疗中强迫观念和强迫行为之间关系的重要性。
