This study was conducted to assess the predictive utility of self-este
em and dispositional optimism to postpartum depression. Forty-five Bri
tish women completed standard measures of self-esteem, optimism, and p
ostpartum depression several weeks before childbirth. Depression was a
gain measured at two and six weeks postpartum. Optimism was associated
with less depressive symptoms during pregnancy and at two weeks postp
artum, while self-esteem was associated with lower depression over all
three administrations. After controlling for optimism and earlier lev
els of depressive symptoms, self-esteem remained associated with lower
levels of depressive symptoms two weeks postpartum. This suggests tha
t self-esteem and not optimism appears to be a reliable contributing f
actor to the differential susceptibility to depression in the early po
stpartum period. (C) 1997 John Wiley & Sons, Inc.
