Feasibility and acceptability of a motivational interviewing breastfeeding peer support intervention

An uncontrolled study with process evaluation was conducted in three U.K. community maternity sites to establish the feasibility and acceptability of delivering a novel breastfeeding peer-support intervention informed by motivational interviewing (MI; Mam-Kind). Peer-supporters were trained to deliver the Mam-Kind intervention that provided intensive one-to-one peer-support, including (a) antenatal contact, (b) face-to-face contact within 48 hr of birth, (c) proactive (peer-supporter led) alternate day contact for 2 weeks after birth, and (d) mother-led contact for a further 6 weeks. Peer-supporters completed structured diaries and audio-recorded face-to-face sessions with mothers. Semistructured interviews were conducted with a purposive sample of mothers, health professionals, and all peer-supporters. Interview data were analysed thematically to assess intervention acceptability. Audio-recorded peer-support sessions were assessed for intervention fidelity and the use of MI techniques, using the MITI 4.2 tool. Eight peer-supporters delivered the Mam-Kind intervention to 70 mothers in three National Health Service maternity services. Qualitative interviews with mothers (n = 28), peer-supporters (n = 8), and health professionals (n = 12) indicated that the intervention was acceptable, and health professionals felt it could be integrated with existing services. There was high fidelity to intervention content; 93% of intervention objectives were met during sessions. However, peer-supporters reported difficulties in adapting from an expert-by-experience role to a collaborative role. We have established the feasibility and acceptability of providing breastfeeding peer-support using a MI-informed approach. Refinement of the intervention is needed to further develop peer-supporters' skills in providing mother-centred support. The refined intervention should be tested for effectiveness in a randomised controlled trial.
