Peer-Delivered Cognitive-Behavioral Therapy for Postpartum Depression: A Randomized Controlled Trial.

Area of Science:

• Psychiatry
• Psychology
• Public Health

Background:

• Postpartum depression (PPD) affects many mothers, impacting their well-being and the mother-infant relationship.
• Access to effective PPD treatments can be limited, necessitating scalable interventions.

Purpose of the Study:

• To evaluate the efficacy of a 9-week group cognitive-behavioral therapy (CBT) intervention for PPD delivered by trained peers.
• To assess the intervention's impact on PPD and anxiety symptoms, social support, and the mother-infant relationship.

Main Methods:

• A randomized controlled trial involving 73 mothers in Ontario, Canada, with infants under 12 months and PPD symptoms.
• Participants were assigned to an immediate peer-delivered group CBT intervention or a waitlist control group.
• Outcomes were assessed at baseline, 9 weeks, and 6 months for the experimental group.

Main Results:

• The peer-delivered CBT group showed significant reductions in PPD and anxiety symptoms compared to the control group.
• Improvements in depression and anxiety were sustained at the 6-month follow-up.
• Participants also reported decreased negative mother-infant bonding perceptions and anger.

Conclusions:

• Peer-delivered group CBT is an effective treatment for postpartum depression and anxiety.
• The intervention shows potential for improving the mother-infant relationship and is a scalable approach to increase access to care.
• This model offers a viable option to meet the needs of mothers experiencing PPD.
