The research used multiple approaches to investigate if and how group singing can support women with symptoms of postnatal depression (PND). This included a randomised controlled trial (RCT) with 134 mums experiencing symptoms of PND. Women were randomly allocated to one of three programmes for a period of ten weeks:
- group singing
- creative play
- care as normal
Their symptoms of PND were measured at the start, after six weeks, and at the end of the programmes.
As part of the RCT, interviews were held with the mums and with the programme leaders. Separate experiments were conducted to measure the impact of group singing on stress hormones and perceived mother-baby closeness. Finally, surveys were completed by over 2,000 women across England. These explored links between involvement in creative activities and mental wellbeing during pregnancy and the first year of motherhood.
