The prevalence and negative effects of perinatal depression are well known. The Edinburgh Postnatal Depression Scale (EPDS) is a common screening tool for perinatal depression and it is recommended for use by several professional organizations. The current study tested competing EPDS factor structures and assessed EPDS change from intake to 6-week follow-up, and identified demographic correlates in an outpatient obstetric sample. Using a retrospective observational study design, medical records were coded for demographic, mental health, and EPDS patient data (n = 524). Confirmatory factor analysis, t-tests, and ANOVA were utilized. Findings included: (1) a 3-factor model (i.e. anxiety, depression, anhedonia) of the EPDS displayed the best fit to the current data; (2) small declines in all 3 subscales of the EPDS from intake to 6-week follow-up appointments and; (3) demographic correlates of EPDS subscales included history of depression, history of anxiety, race, and pregnancy status (i.e. first child or not). The 3-factor structure can be used in clinical practice to assess perinatal depression in a nuanced fashion. Given that history of depression and anxiety are risk factors for perinatal depression, a thorough assessment of these items in clinical practice is needed.
围产期抑郁的患病率和负面影响是众所周知的。爱丁堡产后抑郁量表（EPDS）是一种常见的围产期抑郁筛查工具，几个专业组织都推荐使用它。本研究测试了 EPDS 的竞争因子结构，并评估了从入组到 6 周随访的 EPDS 变化，并在门诊产科样本中确定了人口统计学相关性。使用回顾性观察研究设计，对医疗记录进行了编码，以获取人口统计学、心理健康和 EPDS 患者数据（n=524）。使用验证性因子分析、t 检验和 ANOVA 进行分析。研究结果包括：（1）EPDS 的 3 因素模型（即焦虑、抑郁、快感缺失）最适合当前数据；（2）从入组到 6 周随访预约，EPDS 的所有 3 个分量表都有轻微下降；（3）EPDS 分量表的人口统计学相关性包括抑郁史、焦虑史、种族和怀孕状况（即第一胎或非第一胎）。3 因素结构可用于临床实践，以细致的方式评估围产期抑郁。鉴于抑郁和焦虑史是围产期抑郁的危险因素，因此需要在临床实践中对这些项目进行全面评估。
