A study examined the impact of childhood exposure to domestic violence and abuse (DVA) on adult relationships and the experiences of mental health nurses (MHNs) in the United Kingdom. Using a qualitative descriptive design, researchers conducted semi-structured interviews with 11 MHNs to explore their perceptions and clinical experiences related to DVA. Five key themes were identified: the conceptualization of DVA, the mental health consequences and trauma triggers, the role of MHNs, psychological interventions and interprofessional collaboration, and the long-term impact of DVA on adult relationships. The study revealed significant gaps in MHN training for trauma-informed care, along with systemic obstacles such as time constraints and limited access to specialized services. These challenges hinder the ability of MHNs to effectively support individuals affected by childhood DVA. The researchers concluded that enhancing education on DVA, standardizing trauma-informed practices, and improving interprofessional collaboration are crucial steps to strengthen MHN support and help break the cycle of intergenerational violence.
