Validation of the Edinburgh Postnatal Depression Scale (EPDS) as a screening tool for postnatal depression in Samoan and Tongan women living in New Zealand.

Abstract

The EPDS was an acceptable and valid tool for PND screening in English, Samoan and Tongan languages amongst Samoan and Tongan women. The cut-offs for PND screening were dissimilar in the two groups with a ≥10 for Tongan and ≥11 for Samoan women. A higher cut-off of ≥16 for Tongan and ≥17 for Samoan women improves the predictive value of the instrument.
