Background: The alarming prevalence of teen mothers’ exposure to perinatal intimate partner violence (IPV, 8.3-67%) and attachment disorders (ADs) among their children is a global concern, especially in sub-Saharan Africa with high teenage pregnancy rates. This study, therefore, aimed to examine the link between teen IPV and AD in their offspring. We sought also to explore the mediating roles of postpartum depression symptoms, maternal sensitivity, parenting stress, and perceived social support in the relationship between perinatal IPV and children’s ADs.
