Screening for perinatal-occurring obsessive-compulsive disorder (OCD) is rare. We sought to evaluate the Dimensional Obsessive-Compulsive Scale (DOCS) as a screening tool for perinatal OCD and compare the screening accuracy of the DOCS with the commonly recommended Edinburgh Postnatal Depression Scale (EPDS). English-speaking, pregnant individuals aged 19+ (N = 574) completed online questionnaires and diagnostic interviews to assess for OCD prenatally and twice postpartum. The DOCS total score demonstrated the highest level of accuracy. Neither the EPDS-Full nor the three-item Anxiety subscale of the EPDS (EPDS-3A) met the criteria of a sufficiently accurate screening tool for OCD at any of the assessment points. Findings provide support for the DOCS as a screening tool for perinatal OCD and indicate a need for disorder-specific screening for perinatal anxiety and their related disorders (AD). Generalizability of findings is limited to Canada only. Future research would benefit from comparisons with measures of perinatal OCD (e.g., the Perinatal Obsessive-Compulsive Scale).

筛查围产期发生的强迫症 (OCD) 很少见。我们试图评估维度强迫量表 (DOCS) 作为围产期强迫症的筛查工具，并将 DOCS 的筛查准确性与通常推荐的爱丁堡产后抑郁量表 (EPDS) 进行比较。19 岁以上的讲英语的孕妇（N= 574) 完成了在线问卷调查和诊断访谈，以评估产前和产后两次的强迫症。DOCS 总分显示出最高水平的准确性。EPDS-Full 和 EPDS 的三项焦虑子量表 (EPDS-3A) 在任何评估点均不符合足够准确的 OCD 筛查工具标准。研究结果支持 DOCS 作为围产期强迫症的筛查工具，并表明需要针对围产期焦虑及其相关疾病 (AD) 进行疾病特异性筛查。结果的普遍性仅限于加拿大。未来的研究将受益于与围产期强迫症措施的比较（例如，围产期强迫症量表）。
