Sample selection procedure for evaluation of the effect of women’s groups on postpartum psychological distress.

From 25,595 births and deaths (‘events’) over the 24 study months in 2010 and 2011 we excluded data from: 17,181 events that did not occur within the SRQ-20 data collection periods; 62 events where it was not possible to conduct an interview due to migration or refusal; 1945 events associated with mothers who were temporary residents in the study area; nine events associated with a maternal death; 100 events associated with mothers who had previously delivered during the SRQ-20 data collection periods, either because of multiple births or through repeated births; 23 mothers due to missing SRQ-20 data. In total, 6275 mothers were included in the final sample.

There is an error in the third sentence of the Statistical Analysis subsection of the Methods. The correct sentence is: We used an SRQ-20 score >6 to report the prevalence of psychological distress because a previous study in urban Bangladesh found that this score discriminated best for psychiatric disorders, though the sensitivity (62%) and specificity (69%) were quite low [28].

There is an error in the second sentence of the Results section. The correct sentence is: In total, data were available for 25,595 births and deaths over the study months in 2010 and 2011.

There is an error in the first sentence of the Impact of the women’s groups on postpartum psychological distress section of the Results. The correct sentence is: Using a cut-off score of >6, the overall prevalence of postpartum psychological distress was 35% (2208/6275) (Table 3).
