Victims of childhood maltreatment are at risk of experiencing intimate partner violence later in life, and we do not yet fully understand why. In particular, we do not know whether being maltreated can cause some people to enter relationships that put them at risk of more harm, or if the same risk factors increase risk of childhood maltreatment and intimate partner violence, and this is what causes revictimisation. This project aims to clarify if childhood maltreatment can have a causal effect on later intimate partner violence when considering the genetic and environmental risk factors common to both events. To address this research question, we analyse large population- based datasets (the Twin Early Development Study and the UK Biobank) using methods that take into account genetic differences between people.

Individuals who experienced childhood maltreatment often face challenges in forming healthy intimate relationships. Interventions that help promote relationship well-being are not always available or effective. Through collaboration with third-sector organizations, this project aims to establish a partnership with experts by experience and co-develop research on preventing intimate partner violence. This partnership will enable a better understanding of relationship challenges among individuals who experienced childhood maltreatment, as well as identifying research gaps and strategies that may drive meaningful change in their lives.
