Background and study aims
Postpartum depression (PPD) is a type of depression that many women experience after having a baby. Women who have suffered from PPD are twice as likely to experience future episodes of depression over a 5-year period. PPD can affect mother-infant interactions and lead to child neglect or abuse and marital stress resulting in separation or divorce. Mother and infant deaths are rare but real consequences of PPD. Effective treatment of PPD is needed to not only help the mother but also to prevent these consequences. Antidepressant medication, cognitive behavioural therapy and interpersonal psychotherapy (IPT) are effective treatments for general depression. However, mothers are often reluctant to take antidepressants due to concerns about their transmission in breast milk or potential side effects. Although there is evidence that antidepressants are relatively safe for breastfed infants, it is important that non-drug treatments are tested for use with mothers. IPT may be an effective treatment for PPD. IPT is a brief manual-based psychotherapy that addresses relationship issues in depression. Generally, IPT consists of 12 to 20 weekly sessions lasting 50 to 60 minutes that may be provided by psychiatrists and a range of non-medical health professionals, including nurses. Unfortunately, IPT is not widely available, especially in rural and remote areas. To improve access to care, telepsychiatry has been introduced – this involves providing therapy by telephone. The aim of this study is to test the effect of telephone-based IPT on the treatment of PPD.
Who can participate?
Mothers who have had a baby 2 to 24 weeks ago and have PPD
What does the study involve?
Participants are randomly allocated to one of two groups. The intervention group receive usual postpartum care plus the telephone-based IPT. The telephone IPT includes 12 sessions with a highly trained IPT nurse. Each session is 50 minutes long and is scheduled on a weekly basis. The other group receive usual postpartum care. All participants are telephoned by one of our research nurses after 3, 6 and 9 months to ask about how they are feeling and the healthcare services they have used.
What are the possible benefits and risks of participating?
At the end of the study all participants receive a small token of appreciation. There are no known risks to participants.

Scientific title | A randomised controlled trial to evaluate the effectiveness of telephone-based interpersonal psychotherapy for the treatment of postpartum depression |
Study objectives | Primary question: What is the effect of telephone-based Interpersonal Psychotherapy (IPT) by trained nurses on Postpartum Depression (PPD) at 12 weeks post-randomisation (i.e., immediately post-treatment for mothers in the intervention group)? Secondary questions: What is the effect of telephone-based IPT by trained nurses on: 1. PPD at 24 and 36 weeks post-randomisation (i.e., 12 and 24 weeks post-treatment for mothers in the intervention group)? 2. Depressive symptomatology at 12, 24, and 36 weeks post-randomisation? 3. Anxiety at 12, 24, and 36 weeks post-randomisation? 4. Social functioning at 12, 24, and 36 weeks post-randomisation? 5. Health service utilisation from randomisation to 36 weeks post-randomisation? Amended as of 12/06/2009: The following secondary question has been amended: 4. Attachment at 12, 24, and 36 weeks post-randomisation? The following secondary question has been added: 6. Relationship quality and adjustment at 12, 24, and 36 weeks post-randomisation? Other research questions: 1. What are the cost implications of IPT versus usual care, from a societal perspective? 2. What are mothers evaluations of their IPT experience? 3. What are nurses evaluations of their experience in providing IPT? 4. What are nurses reports of the type and intensity of their IPT activities? |
