P. Boyce et al., THE EDINBURGH POSTNATAL DEPRESSION SCALE - VALIDATION FOR AN AUSTRALIAN SAMPLE, Australian and New Zealand Journal of Psychiatry, 27(3), 1993, pp. 472-476
One hundred and three post-partum women completed the Edinburgh Postna
tal Depression Scale (EPDS) and were interviewed using the Diagnostic
Interview Schedule. A cut-off score of 12.5 on the Edinburgh Postnatal
Depression Scale identified all nine women who reached criteria for m
ajor depression. At this threshold the sensitivity (the percentage of
true ''cases'' identified) of the EPDS was 100%, its specificity (the
percentage of true ''non-cases'' identified as such) 95.7% and its pos
itive predictive value (the percentage of all those tested as positive
who were correctly identified as such) 69.2%. Although this study sup
ported the validity of the EPDS, a replication of this study on a larg
er sample is suggested.
