Objective To develop and validate a brief screening instrument for postpartum depression in resource‐constrained primary care settings. Method Secondary data analysis of a cohort of 305 mothers (Mdn age = 26) attending well‐child check‐ups in six primary care centers in Santiago, Chile, answered the Edinburgh Postnatal Depression Scale (EPDS), the 36‐Item Short Form Health Survey, and the Mini International Neuropsychiatric Interview depression module. A predictive model for postpartum depression was built using logistic and least absolute shrinkage and selection operator regressions, with bootstrap validation. Results A three‐item version of the EPDS exhibited excellent discriminative capacity ( c statistic = 0.95) and showed no significant differences versus the full version of the EPDS ( χ 2 (1) = 1.75, p = .187). The best trade‐off between sensitivity (92.86%) and specificity (86.70%) was achieved at a cut‐off score of 8/9. Conclusions The three‐item version of the EPDS can save clinicians valuable time, which might potentially improve communication of results to patients.
