A 9-month randomized controlled study of 47 depressed mothers receiving either interpersonal psychotherapy or treatment as usual, and their 6- to 18-year-old children (12), found that symptom improvement in mothers receiving interpersonal psychotherapy was statistically significant at 12 weeks,and the treatment effects on children were significant at 9 months. Two other randomized controlled trials testing the effects of maternal treatment on children included much younger children(ages 2–4 and 4–11)and found that there were no statistically significant treatment effects on children(13,14).
