Abstract
Individuals who experience intimate partner violence (IPV) often report posttraumatic stress disorder (PTSD) and depressive symptoms and IPV-related head trauma (IPV-HT), which can also affect mental health. We aimed to estimate rates of IPV-HT and examine the unique associations of IPV, HT, and IPV-HT with PTSD and depression symptom severity in a community-based sample of cohabitating couples. A total of 413 participants (216 women, 1 non-binary) self-reported lifetime history of HT and physical IPV. Chi-square analyses and Fisher’s exact tests were used to compare the proportion of women and men who reported IPV-HT. Kruskal–Wallis tests with Dunn’s post-hoc testing and Bonferroni correction were used to compare symptom severity across five groups: (a) IPV-HT, (b) non-IPV-related HT (Other HT) with exposure to physical IPV (IPV-Other HT), (c) Other HT without exposure to physical IPV (No IPV-Other HT), (d) no exposure to HT with exposure to physical IPV (IPV-No HT), and (e) no exposure to HT without exposure to physical IPV (No IPV-No HT). A greater proportion of women than men reported IPV-HT from a fight or being strangled (fight: 50.0% vs. 3.6%, p < .001; Strangulation: 74.1% vs. 3.8%, p < .001). The IPV-HT and IPV-Other HT groups endorsed greater PTSD and depression symptom severity compared to all individuals with no history of physical IPV, regardless of HT exposure (IPV-No HT and IPV-Other HT groups). No differences in symptom severity between the IPV-HT and the other IPV groups (No HT and Other HT) were found. These results suggest that PTSD and depression symptom severity may be driven by experiencing physical IPV, with some exacerbation due to experiencing HT of any etiology. Future work seeking to examine the effects of IPV-HT on PTSD and depression symptom severity should consider any history of physical IPV and any additional HT exposures.
