About the trial

What the trial wants to find out

This is a randomized controlled trial with an intervention of Center M compared to treatment as usual. Center M consists of weekly digital one-hour group sessions led by a trained therapist aligned with mindfulness based cognitive therapy. Changes in perinatal depression symptoms will be compared between groups.

The 2 groups in the trial

  • Center MTreatment being tested

    In addition to standard prenatal care, participants will participate in Center M sessions, which are weekly one-hour digital group sessions led by a therapist. Each group will include 3-6 participants. The Center M session structure aligns with mindfulness-based cognitive therapy by including mental well-being, core mindfulness and cognitive behavioral therapy skills, in-session practice of skills, and home practice skills. Center M content teaches skills that increase capability for effectively navigating general life stress and the unique stresses of pregnancy and parenting.

  • Treatment as Usual (TAU)No study treatment, for comparison

    Those randomized to TAU will receive prenatal care as it is standardly delivered in their provider's clinical setting, including perinatal screenings and related educational handouts. Participants will be able to engage in any services recommended by their primary prenatal provider or that they voluntarily initiate, including mental health treatment. Participants will not be proscribed from engaging in other recommended interventions or care.
