Abstract

Intimate partner violence (IPV) is widely recognized as a significant public health concern, resulting in substantial physical and psychological harm, particularly among women. IPV refers to abuse occurring within intimate relationships and is linked to a range of neurological injuries, such as traumatic brain injuries (TBIs), as well as adverse mental health outcomes like post-traumatic stress disorder (PTSD). Although IPV and its effects have been extensively studied, there remains a gap in research both globally and within South Africa exploring the overlap between IPV, general and IPV-specific TBIs, and PTSD outcomes. Specifically, the literature lacks a thorough understanding of the prevalence of, and mechanisms for IPV-related TBIs, their severity and their link to PTSD. This study employed a cross-sectional, quantitative approach to examine IPV exposure, TBIs (both general and IPV-specific) and PTSD outcomes in a sample of South African women (N = 81) using self-report measures, including a Demographic Questionnaire and Asset Index, Primary Care PTSD Screen for DSM-5, Life Events Checklist for DSM-5, Women Abuse Screening Tool, and Brain Injury Screening Questionnaire. The results demonstrated a high prevalence of IPV within the sample, with physical and emotional abuse being the most frequently co-occurring forms thereof. IPV-related TBIs were also commonly reported. Simple regression analyses indicated that IPV-related TBIs were a significant predictor (p = 0.009) of PTSD outcomes, highlighting the important role of these injuries in psychological distress. However, multiple regression analyses indicated that, collectively, no single variable stood out as the strongest predictor of PTSD outcomes. The findings of this study are largely aligned with existing research regarding the prevalence and effects of IPV. However, there is a clear need for further research to enhance the understanding of the intersection between IPV, TBIs and PTSD. Given the widespread and debilitating nature of IPV, examining its neurological and psychological effects is essential for informing trauma-sensitive interventions, practices, and policies to better support survivors experiencing IPV-related TBIs and associated mental health challenges.
