Study summary

The purpose of this small randomized controlled trial (RCT) is to compare the impact of a brief (16 hour) 3rd trimester mindfulness-based childbirth education program, "Mind in Labor (MIL): Working with Pain in Childbirth," with a standard care/"treatment as usual" (TAU) active control condition of standard hospital- and community-based childbirth education. The MIL group is expected to demonstrate a reduction in fear of labor (less pain catastrophizing and greater childbirth self-efficacy), less perceived pain in labor, less use of pain medication in labor, greater birth satisfaction, and better prenatal and postpartum psychological adjustment compared to the TAU group.

Study arms

  • Experimental
    Mind in Labor (MIL)

    Mind in Labor: Working with Pain in Childbirth (MIL) is a 16-hour mindfulness-based childbirth education course. It is an abbreviated weekend workshop form of the 9-week Mindfulness-Based Childbirth and Parenting (MBCP) education program, which is a tailored form of Mindfulness-Based Stress Reduction.

    Behavioral: Mind in Labor (MIL): Working with Pain in Childbirth

  • Active comparator
    Treatment As Usual (TAU)

    Treatment As Usual (TAU) refers to standard hospital- and community-based childbirth preparation courses (high quality childbirth education that excludes a mindfulness or mind/body stress reduction focus).

    Behavioral: Treatment as usual (TAU)

Interventions

  • BehavioralMind in Labor (MIL): Working with Pain in Childbirth

    The Mind in Labor (MIL) mindfulness intervention for pregnant women and their partners integrates mindfulness strategies for coping with labor pain and fear and formal mindfulness meditation with traditional childbirth education. The MIL intervention is held over 3 consecutive weekend days (Friday - Sunday) for a total of 16 hours of mindfulness skills training for childbirth preparation and labor pain management. Mindfulness strategies for coping with labor-related pain and fear are taught in an interactive, experiential format, with periods of didactic instruction.

  • BehavioralTreatment as usual (TAU)

    The treatment as usual "TAU" active comparison condition includes participation in a standard care childbirth education course, chosen by participants in the TAU arm from a pre-approved list of hospital- and community-based childbirth education courses comparable in length and quality to MIL, but without any mindfulness meditation, mindful movement/yoga, or other core mind/body component (e.g., hypnosis).
