Couples problem-solving therapy for perinatal women living with HIV and male partners in Malawi: a study protocol for a pilot trial of Mphatso

Introduction Perinatal depression is a common, yet understudied, mental health disorder among women and contributes to poor engagement in prevention of mother-to-child transmission (PMTCT) of HIV in sub-Saharan Africa. Male partners are positioned to provide critical forms of social and economic support during pregnancy and postpartum, and also may contribute to women's stress, depression and anxiety through intimate partner violence and withholding of social support.

Despite the critical role of men in pregnancy outcomes and HIV prevention, few interventions have engaged men around women's depressive symptoms, nutrition and health, and engagement in PMTCT. We will conduct a pilot trial of Mphatso, a couple-based intervention based on problem-solving therapy with couple relationship skills to reduce depressive symptoms in perinatal women, improve food insecurity and prevent HIV transmission to the infant.

Methods and analysis We will employ a two-arm pilot randomised controlled trial in the Zomba district of Malawi to assess the feasibility and acceptability of Mphatso (meaning 'gift' or the child) and explore health impacts on depressive symptoms, PMTCT engagement and food insecurity.
