Optimizing knowledge and behavioral intention of women and their partners in the perinatal period in South Africa: a randomized control trial study protocol in the Tshwane district, Gauteng province, South Africa

BACKGROUND: Maternal knowledge that motivates improvements in critical perinatal health behaviors has the potential to significantly reduce maternal and neonatal mortality. However, evidence-based health information often fails to reach mothers and their partners. mHealth video micro-messages, which disseminate evidence-based perinatal health messages, have the potential to address this gap. METHODS: The study will make use of a mixed method design, using both qualitative and quantitative methods. The study consists of two phases. During Phase 1, qualitative in-depth interviews will be used as part of a human-centered design approach to co-create 10 videos on priority perinatal behaviors. During Phase 2, quantitative methods (a randomized control trial) will be used to test the effectiveness of the videos in improving maternal knowledge and intended behavioral change. DISCUSSION: We hypothesize that by engaging mothers and their partners through emotive, resonant narratives and visuals, we can facilitate the delivery of evidence-based health messages at the foundation of perinatal health, thereby motivating life-saving improvements in health behaviors during the perinatal period.
