A validity study of the Edinburgh Postnatal Depression Scale (EPDS) against the Research Diagnostic Criteria (RDC) was carried out on a sample of women attending a health care center in Santiago. One hundred and eight middle-class mothers filled in the EPDS and were later interviewed by the main author using the Psychiatric Assessment Schedule (PAS). The internal consistency of the EPDS was reasonably good (Cronbach's alpha 0.77). Validity coefficients for the scale were calculated to determine the best case/non-case threshold which was found to be 9/10. Sensitivity, specificity and positive predictive value for this threshold were 100%, 80% and 37% correspondingly. The same best cut-off point (9/10) was found by other Chilean investigators in a sample of working-class women. The EPDS was shown to be a useful screening instrument for postnatal depression in these settings.
针对爱丁堡产后抑郁量表（EPDS）与研究诊断标准（RDC）的效度研究，在圣地亚哥一家医疗中心的女性样本中展开。108名中产阶级母亲填写了EPDS，随后主要作者使用精神评估量表（PAS）对她们进行了访谈。EPDS的内部一致性相当良好（克朗巴哈系数α为0.77）。计算了该量表的效度系数，以确定最佳的病例/非病例阈值，发现为9/10。此阈值的敏感性、特异性和阳性预测值分别为100%、80%和37%。其他智利研究人员在一个工人阶级女性样本中也发现了相同的最佳临界点（9/10）。在这些情况下，EPDS被证明是一种用于产后抑郁的有用筛查工具。
