Treatment of depressed mothers of depressed children: pilot study of feasibility.

Numerous studies have shown that depression is highly familial and impairing and that a history of depression in a parent is the strongest risk factor for depression in a child. Many of the parents in these studies have never received sustained treatment despite histories of recurrent depression. None of the studies have examined the effects of maternal symptom remission on offspring symptom or functioning. We sought to determine the feasibility of treating depressed mothers who brought an offspring for the treatment of depression and to examine the relationship between improved maternal depression and symptomatic improvement and social functioning in their offspring. Nine mothers bringing their offspring for treatment of depression, and who were evaluated and found to be currently depressed, completed a 12-week open trial of interpersonal psychotherapy. Mothers and their depressed offspring were assessed by independent evaluators at weeks 0, 6, and 12 for depressive symptomatology and social functioning. Although the rates of depression were high among the mothers, few eligible mothers agreed to participate. Of the 12 who entered treatment, 9 (75%) completed it. Mothers and offspring improved with regard to depressive symptomatology and global functioning over the course of the trial. Improvement in maternal depression was significantly associated with improvement in offspring functioning but not symptom reduction. Improvement of maternal depression may be associated with improved outcomes in depressed offspring. However, it is difficult to engage depressed mothers in treatment for themselves if they come to the clinic to bring their child for treatment of depression. It may be more feasible to study the effect of improved maternal depression on offspring by sampling depressed mothers coming for their own treatment and then assessing their children over the course of maternal treatment.
