Background: Postpartum depression causes women great suffering and has nega
tive consequences for their social relationships and for the development of
their infants, Research is needed to evaluate the efficacy of psychotherap
y for postpartum depression.
Methods: A total of 120 postpartum women meeting DSM-TV criteria for major
depression were recruited from the community and randomly assigned to 12 we
eks of interpersonal psychotherapy (IPT) or to a waiting list condition (WL
C) control group. Subjects completed interview and self-report assessments
of depressive symptoms and social adjustment every 4 weeks.
Results: Ninety-nine of the 120 patients completed the protocol. Hamilton R
aring Scale for Depression (HRSD) scores of women receiving IPT declined fr
om 19.4 to 8.3, a significantly greater decrease than occurred in the WLC g
roup (19.8 to 16.8). The Beck Depression Inventory (BDI) scores of women wh
o received IPT declined from 23.6 to 10.6 over 12 weeks, a significantly gr
eater decrease than occurred in the WLC group (23.0 to 19.2). A significant
ly greater proportion of women who received IPT recovered from their depres
sive episode based on HRSD scores of 6 or lower (37.5%) and BDI scores of 9
or lower (43.8%) compared with women in the WLC group (13.7% and 13.7%, re
spectively). Women receiving IPT also had significant improvement on the Po
stpartum Adjustment Questionnaire and the Social Adjustment Scale-Self-Repo
rt relative to women in the WLC group.
Conclusions: These findings suggest that IPT is an efficacious treatment fo
r postpartum depression. Interpersonal psychotherapy reduced depressive sym
ptoms and improved social adjustment, and represents an alternative to phar
maco therapy, particularly for women who are breastfeeding.
