EPDS/Cox 1987: 10 items, 7 days; Brazilian Pelotas 2007 cutoff ≥10 versus original ≥13; item 10 alert

Screening for depressive symptoms after childbirth. The Pelotas validation administered the questionnaire three months after birth and found a ≥10 screening cutoff. That context does not define a universal window or automatically validate use in other populations or new translations.

Sources and documentation

Documented formula

Transcribed from the source or a recorded revision; this is not a clinical recommendation.

10 items about the past 7 days, each scored from 0 to 3 points. In the order of Cox’s original form (1987), items 3 and 5 to 10 are reverse scored; items 1, 2 and 4 are scored from 0 to 3. On this platform, all options are already ordered by their score from 0 to 3: add the points for the selected responses without reversing them again. Total score from 0 to 30.

Brazilian screening cutoff: 10 points (Santos 2007, Pelotas cohort: sensitivity 82.6%, specificity 65.4%). Cox (1987) proposed ≥ 13 for probable depression. Any score on item 10 requires immediate suicide-risk assessment, irrespective of total.
