Differential Predictors of Postpartum Depression and Anxiety: The Edinburgh Postnatal Depression Scale Hebrew Version Two Factor Structure Construct Validity

Objectives Postpartum anxiety (PPA) is as prevalent and disruptive as postpartum depression (PPD), although less commonly addressed. The Edinburgh Postnatal Depression Scale (EPDS), originally created to screen for PPD, was found to include anxiety and depression subscales. This study examined the construct validity of the EPDS PPD and PPA subscales by examining differential predictors of both in a structural regression model. Methods Women (n = 969) were recruited from a maternity ward in Jerusalem, Israel and completed a demographic survey; 715 (74%) women were screened for PPD and PPA at 6 weeks postpartum using the EPDS. Results History of depression was a significant predictor of PPD symptoms and PPA symptoms. Income and number of past pregnancies were significant predictors of PPA symptoms. Conclusions for practice PPD and PPA have different predictors, suggesting that the EPDS depression and anxiety subscales should be scored separately. Further assessment and treatment should be tailored to specific symptoms of depression and/or anxiety reported.
