The MAMAACT intervention aimed to address ethnic and social disparity in stillbirth and infant health by improving management of pregnancy complications. This process evaluation of the intervention was guided by the British Medical Research Council’s framework. We examined implementation through dose, reach, and fidelity, important mechanisms and the influence of contextual factors. The intervention included a six-hour training session for antenatal care (ANC) midwives in intercultural communication and cultural competence, two follow-up dialogue meetings, and health education materials (leaflet and app) on warning signs of severe pregnancy complications and how to respond for pregnant women. A mixed-methods approach was applied. Cross-sectional survey data and administrative data were used to assess intervention reach and dose. Qualitative data (records from dialogue meetings with midwives, participant observations and field notes from ANC visits, focus group interviews with midwives, and individual interviews with non-Western immigrant women) evaluated intervention fidelity, mechanisms, and contextual barriers. More than 80% of women received the MAMAACT leaflet and many found the content useful. The app was used more selectively. Midwives described being more aware and reflective in their communication with women from various cultural backgrounds. Organizational factors in ANC (time pressure, lack of flexibility in visits, poor interpreter services), barriers in women’s everyday life (lack of social network, previous negative experiences/lack of trust and domestic responsibilities), and habitual interaction patterns among midwives served as contextual barriers. The reach of the intervention was high and it was evaluated positively by both pregnant women and midwives. Organizational factors hindered changes towards more needs-based communication in ANC potentially hindering the intended mechanisms of the intervention. When interpreting the intervention effects, attention should be drawn to both organizational and interpersonal factors in the clinic as well as the pregnant women’s life situations.
