One hundred and three post-partum women completed the Edinburgh Postnatal Depression Scale (EPDS) and were interviewed using the Diagnostic Interview Schedule. A cut-off score of 12.5 on the Edinburgh Postnatal Depression Scale identified all nine women who reached criteria for major depression. At this threshold the sensitivity (the percentage of true "cases" identified) of the EPDS was 100%, its specificity (the percentage of true "non-cases" identified as such) 95.7% and its positive predictive value (the percentage of all those tested as positive who were correctly identified as such) 69.2%. Although this study supported the validity of the EPDS, a replication of this study on a larger sample is suggested.
103名产后女性完成了爱丁堡产后抑郁量表（EPDS）测试，并通过诊断访谈表进行了访谈。爱丁堡产后抑郁量表得分12.5分的临界值能够识别出所有符合重度抑郁标准的9名女性。在此临界值下，爱丁堡产后抑郁量表的敏感度（识别出的真“病例”百分比）为100%，特异度（被正确识别为真“非病例”的百分比）为95.7%，阳性预测值（所有检测为阳性且被正确识别为阳性的百分比）为69.2%。尽管本研究支持了爱丁堡产后抑郁量表的有效性，但建议在更大样本上重复本研究。
