Comparison of the Edinburgh Postnatal Depression Scale and the Whooley questions in screening for postpartum depression in Japan

AbstractObjective: We examined the clinical utility of the Whooley questions in comparison with that of the Edinburgh Postnatal Depression Scale (EPDS) in Japan.Methods: We carried out mental health screening of all postnatal mothers (n = 258) who gave birth to singleton babies at term attending our hospital using the EPDS and the Whooley questions. For the EPDS, scores were calculated, and a score of nine points or more was regarded as “positive screening” according to the results of previous observations in Japan. For the Whooley questions, if at least one question was answered “yes,” we diagnosed it as “positive screen.”Results: The positive rate of the Whooley questions was 16.7%, while that of the EPDS (≥ 9 points) was 14.8% (p = .55). The incidence of postpartum depression was 5.4%. The difference in the sensitivity and positive predictive value of the two tools did not reach significance (p = .09 and .45, respectively).Conclusions: There were no significant differences in accuracy on comparing the ...
