Accuracy of depression screening tools for identifying postpartum depression among urban mothers.

OBJECTIVE: The goal was to describe the accuracy of the Edinburgh Postnatal Depression Scale (EPDS), Beck Depression Inventory II (BDI-II), and Postpartum Depression Screening Scale (PDSS) in identifying major depressive disorder (MDD) or minor depressive disorder (MnDD) among low-income, urban mothers attending well-child care (WCC) visits during the postpartum year. METHODS: Mothers (N = 198) attending WCC visits with their infants 0 to 14 months of age completed a psychiatric diagnostic interview (standard method) and 3 screening tools. The sensitivities and specificities of each screening tool were calculated in comparison with diagnoses of MDD or MDD/MnDD. Receiver operating characteristic curves were calculated and the areas under the curves for each tool were compared to assess accuracy for the entire sample (representing the postpartum year) and subsamples (representing early, middle, and late postpartum time frames). Optimal cutoff scores were calculated. RESULTS: At some point between 2 weeks and 14 months after delivery, 56% of mothers met criteria for either MDD (37%) or MnDD (19%). When used as continuous measures, all scales performed equally well (areas under the curves of > or =0.8). With traditional cutoff scores, the measures did not perform at the expected levels of sensitivity and specificity. Optimal cutoff scores for the BDI-II (> or =14 for MDD and > or =11 for MDD/MnDD) and EPDS (> or =9 for MDD and > or =7 for MDD/MnDD) were lower than currently recommended. For the PDSS, the optimal cutoff score was consistent with current guidelines for MDD (> or =80) but higher than recommended for MDD/MnDD (> or =77). CONCLUSIONS: Large proportions of low-income, urban mothers attending WCC visits experience MDD or MnDD during the postpartum year. The EPDS, BDI-II, and PDSS have high accuracy in identifying depression, but cutoff scores may need to be altered to identify depression more accurately among urban, low-income mothers.

Detection of postpartum depressive symptoms by screening at well-child visits.

OBJECTIVE: To assess 1) the feasibility of universal postpartum depression screening during well-child visits in the first year of life, 2) the prevalence of postpartum depressive symptoms among mothers who attend first-year well-child visits, 3) detection of postpartum depressive symptoms in a pediatric clinic before and after universal screening at each first-year well-child visit, and 4) social work referrals before and after universal screening. METHODS: The practice instituted universal screening for postpartum depressive symptoms during first-year well-child visits using the Edinburgh Postnatal Depression Scale (EPDS). We randomly selected 110 infant medical records before (cohort 1) and 110 after (cohort 2) screening was initiated. Measures included demographics, notation of depression or depressive symptoms in the well-child visit note, and referral for depression. EPDS scores were collected for cohort 2 only. Before-after comparisons were made for detection of depression or depressive symptoms and mental health referrals. RESULTS: The EPDS was included in the medical record in 46% of well-child visits. Eighty-eight percent of these forms were completed. Twenty-one percent of completed EPDS forms had scores > or =10, and 27% of women who completed the EPDS had scores > or =10 sometime during the postpartum year. There was a significant increase in documentation of depressive symptoms with the EPDS after initiation of universal screening (1.6% of visits [cohort 1] vs 8.5% [cohort 2]). Social work referrals for mental health reasons increased significantly (0.2% of visits [cohort 1] to 3.6% [cohort 2]). CONCLUSIONS: Women with high levels of postpartum depressive symptoms are common in an urban population and can be detected at well-child visits throughout the first postpartum year by pediatricians using a standardized screening tool. Because screening for depression during well-child visits is feasible using a standardized screening instrument, pediatricians can play an active role in early detection and referral for postpartum depression.
