: Factor analysis of the Edinburgh Postnatal Depression Scale (EPDS) could result in a shorter and easier to handle screening tool. Therefore, the aim of this study was to check and compare the metrics of two different 6-item EPDS subscales.
: We administered the EPDS to a total of 3,891 women who had given birth between 1 and 3 months previously. We conducted confirmatory and exploratory factor analyses and plotted receiver-operating characteristics (ROC) curves to, respectively, determine construct validity, scale items' fit to the data, and ideal cutoff scores for the short versions.
: A previously defined 6-item scale did not exhibit construct validity for our sample. Nevertheless, we used exploratory factor analysis to derive a new 6-item scale with very good construct validity. The area under the ROC curve of the new 6-item scale was 0.986 and the ideal cutoff score was ≥ 6.
: The new 6-item scale has adequate psychometric properties and similar ROC curve values to the10-item version and offers a means of reducing the cost and time taken to administer the instrument.
对爱丁堡产后抑郁量表（EPDS）进行因素分析可能会得出一个更简短且更易于操作的筛查工具。因此，本研究的目的是检验和比较两种不同的6项EPDS子量表的指标。
我们对总共3891名在1至3个月前分娩的女性进行了EPDS测试。我们进行了验证性和探索性因素分析，并绘制了受试者操作特征（ROC）曲线，以分别确定结构效度、量表项目与数据的拟合度以及简短版本的理想临界分数。
先前定义的6项量表对我们的样本未表现出结构效度。然而，我们使用探索性因素分析得出了一个具有非常好的结构效度的新6项量表。新6项量表的ROC曲线下面积为0.986，理想临界分数为≥6。
新的6项量表具有足够的心理测量学特性，其ROC曲线值与10项版本相似，并提供了一种降低使用该工具的成本和时间的方法。
