Comparison of postpartum and nonpostpartum depression: clinical presentation, psychiatric history, and psychosocial functioning.

This study compared a sample of postpartum women diagnosed with depression with a nonpostpartum depressed group and 2 nondepressed control groups. Women's depressive episodes were compared to determine whether differences existed in symptomatology, previous history, or course. Results indicate that postpartum depression tends to be relatively mild. Both depressed groups had high rates of positive psychiatric history and were equally likely to have recovered at a 6-month follow-up. Groups were also compared on psychosocial variables known to covary with depression: interpersonal relations, stress, and coping. A series of multivariate analyses of covariance showed few differences between the depressed groups that were not attributable to symptom severity, although postpartum depressed women did report better marital relations than did the nonpostpartum depressed women. These findings suggest that there is little to distinguish postpartum from nonpostpartum depression beyond differences in symptom severity.
