Challenges recruiting for a peer support intervention for pregnant teenagers with antenatal depression

Background/Aims Robust research is needed to improve tailored support for perinatal mental health. However, recruitment can be challenging. This study explored why a feasibility randomised controlled trial failed to recruit participants (pregnant women aged 16–19 years with depressive symptoms). Methods Semi-structured interviews (n=18) were carried out with a purposive sample of peer support workers and professionals involved in development and delivery. The data were analysed thematically. Results The themes explored the potential of the intervention and the role of peer support workers, including in further research with pregnant teenagers, and the importance of ongoing engagement and collaboration to design tailored interventions, including practical considerations for working with clinicians. Conclusions Peer support interventions are highly valued in perinatal care by midwives, researchers and peer support workers. There are challenges to overcome in recruiting to and delivering randomised controlled trials on peer support interventions specific to teenagers in an NHS setting, which must be considered carefully. Implications for practice Researchers should co-design health-related interventions and training with midwives and stakeholders, ensuring the role of peer support workers is suitably defined. Openness and honesty in research collaborations is vital to understand and address challenges in recruiting vulnerable groups and how to mitigate against these.
