Data supporting the SHAPER-PND trial: Clinical-, implementation-, and cost-effectiveness of a community singing intervention for postnatal depression: SHAPER-PND, a randomised controlled trial

The SHAPER-PND trial assessed the clinical effectiveness, the implementation effectiveness, and the cost effectiveness of a 10-week community singing intervention (Breathe Melodies for Mums), developed for postnatal depression, compared with already-existing community mother-baby activity groups. Mothers were deemed eligible for the trial if they scored 10 or greater on a screening Edinburgh Postnatal Depression Scale for postnatal depression, and if their babies were aged 0-9 months. Once consented and enrolled, mothers were randomly allocated to either the singing intervention group (Breathe Melodies for Mums) or the active wait-list control group (community mother-baby activity group) for 10 weeks. At baseline (pre-intervention), mothers were assessed for various aspects of their sociodemographics, mental health, and health services usage. Mothers then re-completed questionnaires regarding their demographics, mental health, health service usage during the intervention period at weeks 6 and 10 and then again in the study follow-up period at weeks 20 and 36. Furthermore, mothers in both groups completed questionnaires about the feasibility, acceptability, and appropriateness of the group they were allocated to, mid-intervention at week 6. Mothers in the control group were offered a block of singing sessions upon completion of their intervention period so that everyone enrolled in the trial was able to access the singing intervention.
