Depression, anxiety, and posttraumatic stress in women with and without brain injuries due to intimate partner violence: Psychometric evaluation of measurement approaches and group comparisons.

The sample was recruited online, was predominantly non-Hispanic White, and highly educated, which may not represent the general population of IPV survivors who often face barriers to care. All data, including brain injury history and mental health symptoms, were self-reported without medical confirmation or diagnostic interviews. The study relied on retrospective recall of injuries and violence, which can be inaccurate due to trauma and the passage of time (average 10-11 years since last injury). A small number of participants reported only hypoxic-ischemic injuries, and the duration of these events was not measured, making it difficult to confirm if neurological injury actually occurred. The cross-sectional design cannot establish causality between IPV-related brain injuries and mental health outcomes.

The authors declared no conflicts of interest. The study was funded by the National Institute on Deafness and Other Communication Disorders (NIDCD) and the National Institute of Neurological Disorders and Stroke (NINDS).

Do not conclude that brain injuries from partner violence cause worse mental health outcomes independent of the violence itself. The study found that when the severity of physical and sexual abuse was accounted for, the differences in depression, anxiety, and PTSD symptoms between women with and without brain injuries disappeared.
