Effectiveness of Sertraline Alone and Interpersonal Psychotherapy Alone in Treating Women With Postpartum Depression
Effectiveness of Sertraline Alone and Interpersonal Psychotherapy Alone in Treating Women With Postpartum Depression
This study will evaluate the effectiveness of antidepressant medication alone and
 interpersonal psychotherapy alone in treating women with postpartum depression.
Postpartum depression (PPD) occurs in approximately 13% of postpartum women. The impact of
 PPD is significant, including emotional distress for the woman as well as disturbances in
 infant development. Common signs of depression after childbirth may include anxiety,
 irritability, low energy, and lack of concern for self or infant. If left untreated, PPD may
 last for more than 1 year, causing strain on family life and the mother's relationship with
 her infant. Infants of depressed mothers are also at a higher risk for developmental delays,
 behavioral problems, and difficulty eating and sleeping. Despite the public health
 significance of PPD, relatively little research has been done to determine the most effective
 treatments. Specifically, there is a lack of research concerning the use of antidepressant
 medication for treating PPD. Interpersonal psychotherapy (IPT), which focuses on
 interpersonal issues related to depression, has been more thoroughly studied for the
 treatment for PPD, but it has not been compared to the other treatment. This study will
 evaluate the effectiveness of antidepressant medication alone and IPT alone in treating women
 with PPD.

 Participation in this double-blind study will last 9 months. Participants will first undergo
 initial assessments, which include interviews about depressive symptoms, self-report forms
 about medical history, blood tests, and a pregnancy test. Participants will then be randomly
 assigned to one of three treatments: sertraline, placebo, or IPT. All three treatments will
 be administered over 13 weeks. Participants assigned to take sertraline or placebo will
 attend nine 30-minute sessions over the 13-week treatment period. During these sessions,
 participants will be administered the study medication and will be assisted with parenting
 issues and skills by a psychiatrist. Participants receiving IPT will attend weekly 50-minute
 sessions over the 13-week treatment period. These sessions will focus on improving
 relationships with others, setting goals, and increasing coping skills. All participants will
 also complete interviews and questionnaires about their depression once a month. Following
 the 13 weeks of treatment, participants will undergo follow-up assessments at Months 3 and 6
 post-treatment. Follow-up assessments will repeat initial interviews and questionnaires and
 will include a form about the infant's nature.
