Brief summary

This feasibility and acceptability pilot evaluates a one-day antenatal group workshop designed to mentally prepare first time mothers for the early postpartum months, and support adjustment during this time. The workshop covers practical coping skills, mindfulness and acceptance strategies, self-compassion, and how to build confidence in parenting and bonding with baby. In their third trimesters of pregnancy, participants will be randomly allocated to either the workshop group or the no workshop group (care as usual). We plan to assess whether the study is feasible and acceptable to participants. We will also preliminarily explore whether increasing psychological flexibility, self-compassion, and parental self-efficacy helps to support better postpartum adjustment - that is, less distress and better coping. This will be measured using brief online questionnaires (2 during pregnancy and 2 postpartum at approximately 6 and 12 weeks post birth). We hypothesise that the workshop will be feasible to deliver, acceptable to participants, and indicate effect size trends that show preliminary signs of improving the adjustment to motherhood when compared to usual care.
