Objective. While there is a recommendation to screen for postpartum depression (PPD), there are worries about the validity of instruments other than the Edinburgh Postnatal Depression Scale; little is known about the construct validity of one of the most used screening instruments, the Beck Depression Inventory, in this period. Methods. This study evaluated the validity and reliability of the BDI in a population-based sample of women and their spouses (n=772) in the postpartum. Additionally, we compared factor scores within the couple. Results. Exploratory factor analysis demonstrated a two-factor solution (depressive symptoms and somatic symptoms), accounting for 44.01% of the total variance. Internal consistency was good (Cronbach's α=0.90). Women had higher scores than their partners in both factors (P<0.001), but not a higher proportion of the total score attributable to somatic symptoms. Conclusion. With little factor variance between women and men, and a similar proportion of somatic symptoms, these results should be taken to reinforce the validity of the BDI in the postpartum.
虽然有建议对产后抑郁症（PPD）进行筛查，但人们对爱丁堡产后抑郁量表以外的其他工具的有效性存在担忧；在这一时期，人们对最常用的筛查工具之一贝克抑郁量表的结构效度知之甚少。
本研究评估了 BDI 在基于人群的产后妇女及其配偶样本（n=772）中的有效性和可靠性。此外，我们还比较了夫妇内的因子得分。
探索性因子分析显示，双因素解（抑郁症状和躯体症状），占总方差的 44.01%。内部一致性较好（Cronbach's α=0.90）。女性在两个因子上的得分均高于其伴侣（P<0.001），但归因于躯体症状的总分比例并无差异。
由于男女之间的因子差异较小，且躯体症状的比例相似，这些结果应加强 BDI 在产后的有效性。
