One-Day Peer-Delivered Cognitive Behavioral Therapy-Based Workshops for Postpartum Depression: A Randomized...

Area of Science:

• Mental Health
• Perinatal Psychiatry
• Behavioral Therapy

Background:

• Postpartum depression (PPD) presents significant barriers to timely treatment for birthing parents.
• Existing treatments often face accessibility challenges.

Purpose of the Study:

• To evaluate the effectiveness and cost-effectiveness of a peer-delivered, 1-day cognitive behavioral therapy (CBT)-based workshop added to treatment as usual (TAU) for PPD.
• To assess the impact on PPD, its comorbidities, and related psychosocial factors.

Main Methods:

• A parallel-group, randomized controlled trial conducted in Ontario, Canada, involving 405 participants with PPD.
• Participants received either the CBT workshop plus TAU or TAU alone (with a waitlist for the workshop).
• Primary outcome: change in PPD symptoms (Edinburgh Postnatal Depression Scale - EPDS) at 12 weeks. Secondary outcomes: cost-effectiveness, anxiety, social support, relationship quality, mother-infant relationship, parenting stress, and infant temperament.

Main Results:

• The CBT workshop significantly reduced EPDS scores (mean change from 15.95 to 11.37, p < 0.01) and increased the odds of a clinically significant reduction in PPD symptoms (OR = 2.03).
• The intervention was more cost-effective than TAU alone.
• Improvements were observed in postpartum anxiety, infant-focused anxiety, parenting stress, and infant temperament.

Conclusions:

• Peer-delivered, 1-day CBT workshops offer a scalable, low-intensity treatment option for PPD.
• This intervention can improve PPD symptoms and related comorbidities, potentially increasing treatment access for birthing parents.
