Limited emphasis is placed on understanding the gendered pathways that influence mental health, especially long-term cumulative impacts of gender-based inequalities. Exposure to early child marriage (marriage by age 15) may exaggerate exposure to gender-based mental health risk-factors, providing an opportunity to understand the multi-layered gendered pathways that impact mental health overtime. We used nationally representative cross-sectional data from Ethiopia to examine the relationship between early child marriage and psychological well-being and assessed if intimate partner violence mediates this relationship among young women. We implemented three separate multivariate regression models to assess these relationships. Our results suggest that the relationship between early child marriage and psychological well-being is influenced by higher levels of violence experienced by women in early child marriages as compared to their counterparts who married later. Investments in longitudinal data are needed to rigorously parse out the relationship between early child marriage, intimate partner violence, and psychological well-being.
