Characterizing Intimate Partner Violence-Related Head Trauma in Community-Recruited Women

Objective: The aim of the study was to characterize the experiences of intimate partner violence (IPV)-related head trauma (HT) among cisgender women. Setting: Three geographic regions across the United States. Participants: Seventy-two cisgender women aged 18 to 60 years (mean age = 39.6 years). Design: In-depth semi-structured interviews. Main Measures: Participants completed a semi-structured interview, which was audio-recorded to determine the number and mechanisms of IPV-HT injuries experienced over their lifetime. Quotes from interview transcriptions were used to illustrate how participants describe their IPV-HT episodes. Results: A total of 69/72 cisgender women reported at least 1 injury episode that involved IPV-HT. Participants reported between 1 and 9 injury episodes that involved HT during their lifetimes. Participants reported a total of 240 injury episodes, of which 186 represented a single, isolated injury, while 54 were a repetitive exposure by the same mechanism(s) of injury over time. The time over which an injury episode was repeated ranged from 1 month to 16 years (mean: 4.72 years, standard deviation: 4.70 years). The most frequent mechanisms of injury were blunt force trauma (41.7%) and strangulation (22.1%), while 22.5% of episodes involved multiple mechanisms. The most common within-person overlap of mechanisms was blunt force trauma and strangulation (n = 21, 31%). The interview quotes demonstrated that the true frequency of IPV-HT may be unknown and/or unable to be recalled, highlighting the challenges in capturing accurate IPV-HT exposure within this population even through in-depth interviews. Conclusions: This study provides important information on the experience of HT among women with exposure to IPV. Such findings may improve our ability to characterize and understand the injuries resulting from IPV among women, which may, in turn, benefit existing tools for determining experiences of IPV-HT and probable brain injury.
