Examining the Association Between Childhood Trauma, Brain Injury, and Neurobehavioral Symptoms Among Survivors of Intimate Partner Violence: A Cross-Sectional Analysis

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

PURPOSE/OBJECTIVE

The current study examined the psychometric properties of common mental health questionnaires among women survivors of intimate partner violence (IPV) with and without brain injuries due to IPV and evaluated whether women with and without IPV-related brain injuries differed in depression, anxiety, and posttraumatic stress disorder (PTSD) symptom severity.

RESEARCH METHOD/DESIGN

Women survivors of IPV with and without IPV-related brain injuries were recruited online through Prolific (N = 205, M = 39.8 ± 11.9 years old, 83.9% non-Hispanic White, 42.4% college-educated). They completed the eight-item Patient Health Questionnaire (PHQ-8), seven-item Generalized Anxiety Disorder scale (GAD-7), and PTSD Checklist for the Diagnostic and Statistical Manual of Mental Disorders (fifth edition) (PCL-5). Model fit and internal consistency were estimated for each scale. Groups were compared on mental health symptom severity, with and without controlling for age, education, and IPV severity.

RESULTS

Both one-factor and multifactor models showed excellent fit for all scales. PHQ-8 (ω = .91), GAD-7 (ω = .94), and PCL-5 total scores (ω = .95) had strong reliability, and all subscale scores had acceptable-to-strong reliability (ω range = .79-.94). Women with IPV-related brain injuries reported greater physical IPV severity, higher rates of depression, and higher somatic anxiety and PTSD symptom severity. No group differences in mental health symptoms were significant after controlling for IPV severity.

CONCLUSIONS/IMPLICATIONS

The PHQ-8, GAD-7, and PCL-5 showed evidence for reliability and validity among women survivors of IPV. Women with IPV-related brain injuries had higher PTSD symptom severity, attributable to greater physical violence exposure in general. Brain injury screening among survivors appears warranted for women with extensive physical IPV experiences. Interventions addressing PTSD, violence prevention, and brain injury recovery may best serve this population. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Adverse childhood experiences in adults with chronic traumatic brain injury: Support for a life course approach to brain injury rehabilitation

BACKGROUND

Adverse childhood experiences (ACEs) confer greater risk for adult traumatic brain injury (TBI), but little is known about their effects on post-injury outcomes.

OBJECTIVE

To determine the prevalence and correlates of conventionally defined ACEs (occurring within household/in private; e.g., physical abuse) and community-level ACEs (e.g., bullying) after TBI.

METHODS

Participants were 85 Philadelphia-area TBI Model System participants with chronic (>1 year post-injury) TBI. We examined cross-sectional associations between total conventional and community ACEs reported (out of 21) before age 18, mental health symptoms, and health-related quality of life (HRQoL), as well as relationships between ACEs and neighborhood deprivation (census-derived neighborhood socioeconomic status).

RESULTS

The median number of total ACEs was 3 (range: 0-17). Emotional abuse, physical abuse, and alcohol abuse in the household were the most common conventional ACEs (each at 36.5 %). Witnessing violence (45 %) was the most common community ACE. Black individuals (n = 32) reported more community ACEs (p < .001) than White individuals (n = 45). Community ACEs were significantly associated with greater neighborhood deprivation, though this relationship was confounded by race. Total ACEs was significantly related to more severe mental health symptoms (p < .001) and poorer HRQoL (p = .005), even after covariate adjustment. A fully-adjusted path model supported mental health as a mediator between total ACEs and HRQoL.

CONCLUSIONS

Results of this preliminary study reveal an appreciable prevalence and potential far-reaching consequences of conventional and community ACEs among those with chronic TBI. The results underscore the value of trauma-informed and life course approaches to research and clinical care in TBI.

The Neurobehavioral Symptom Inventory: Psychometric Properties and Symptom Comparisons in Women With and Without Brain Injuries Due to Intimate Partner Violence

This study psychometrically evaluated the Neurobehavioral Symptom Inventory (NSI) among women survivors of intimate partner violence (IPV) and compared symptoms between women with no brain injury history (n = 93) and women with IPV-related brain injury history (n = 112). Women completed the NSI and questionnaires on traumatic brain injury (TBI), hypoxic-ischemic brain injury (HI-BI), and lifetime IPV history. A four-factor NSI model, including affective, somatosensory, cognitive, and vestibular factors, had the best fit (comparative fit index = 0.970, root mean square error of approximation = 0.064), with strong reliability for the total score (ω = .93) and subscale scores (ω range = .72-.89). In group comparisons, women with IPV-related brain injuries reported greater total, affective, and cognitive symptom severity after adjusting for age and education; however, no group differences were observed after adjusting for IPV severity. When examining lifetime number of brain injuries, HI-BI count was independently predictive of total, cognitive, and vestibular symptom severity after adjusting for age, education, and IPV severity; whereas TBI count did not independently predict any NSI scores after adjusting for these covariates. The NSI had acceptable psychometric properties for measuring neurobehavioral symptoms among women survivors of IPV. The association between HI-BI count and cognitive and vestibular symptoms may indicate the importance of studying repetitive nonfatal strangulation as an injury mechanism in this population.

Detecting a hidden pandemic: The current state and future direction of screening and assessment tools for intimate partner violence-related brain injury

Intimate partner violence (IPV) is a major global concern, and IPV victim-survivors are at an increased risk of brain injury (BI) due to the physical assaults. IPV-BI can encompass both mild traumatic brain injury (mTBI) and non-fatal strangulation (NFS), but IPV-BI often goes undetected and untreated due to a number of complicating factors. Therefore, the clinical care and support of IPV victim-survivors could be enhanced by BI screening and assessment in various settings (e.g., first responders, emergency departments, primary care providers, rehabilitation, shelters, and research). Further, appropriate screening and assessment for IPV-BI will support more accurate identifications, and prevalence estimates, improve understanding of health implications, and have the potential to inform policy decisions. Here we overview the seven available tools that have been used for IPV-BI screening and assessment purposes, including the BISA, BISQ-IPV, BAT-L/IPV, OSU TBI-ID, the HELPS, and the CHATS, and outline the advantages and disadvantages of these screening tools in the clinical, community, and research settings. Recommendations for further research to enhance the validity and utility of these tools are also included.

Pediatric Brain Injuries are Associated With Intimate Partner Violence-Related Brain Injuries Among Women in Adulthood

OBJECTIVE

Prior studies have reported associations between childhood physical abuse and intimate partner violence (IPV). However, there has been limited literature examining the relationship between pediatric brain injuries and IPV-related brain injuries later in life. We examined the association between childhood brain injuries and brain injuries sustained from IPV in adulthood.

SETTING

Participants were recruited through Mass General Brigham's "Rally," social media, and information sheets distributed in locations likely to serve women in current or past abusive relationships (eg, domestic violence shelters, and IPV support programs).

PARTICIPANTS

Women who have experienced IPV with and without brain injury (n = 129), ages 19 to 69.

DESIGN

Retrospective, cross-sectional study design.

MAIN MEASURES

We administered the Ohio State University Traumatic Brain Injury Identification Method and the Brain Injury Severity Assessment to assess brain injury history, and the Childhood Trauma Questionnaire (CTQ). A logistic regression was used to examine the association between pediatric brain injuries and IPV-related brain injuries, adjusting for childhood trauma, years of education, and age.

RESULTS

A majority of participants (64.3%) reported experiencing at least 1 IPV-related brain injury, and 30.2% experienced at least 1 childhood brain injury. Child abuse-related brain injuries occurred in 10.9% of the sample, whereas childhood brain injuries from other causes occurred in 19.4% of participants. Participants who sustained at least 1 childhood BI were significantly more likely to sustain a future IPV-related brain injury as an adult (OR = 4.652, P = .004). For each additional childhood BI sustained, participants were more likely to sustain an IPV-related BI (OR = 3.198, P = .005).

CONCLUSION

This study illustrates a high prevalence of childhood brain injuries among women who have experienced IPV and identifies an association between pediatric brain injuries and brain injuries due to partner violence in adulthood. Our findings speak to the urgency of increasing our understanding of childhood brain injuries and whether they or other related factors might confer an increased risk for brain injuries or possibly IPV later in life.

Intimate Partner Violence-Related Brain Injury: Unmasking and Addressing the Gaps

Intimate partner violence (IPV) is a significant, global public health concern. Women, individuals with historically underrepresented identities, and disabilities are at high risk for IPV and tend to experience severe injuries. There has been growing concern about the risk of exposure to IPV-related head trauma, resulting in IPV-related brain injury (IPV-BI), and its health consequences. Past work suggests that a significant proportion of women exposed to IPV experience IPV-BI, likely representing a distinct phenotype compared with BI of other etiologies. An IPV-BI often co-occurs with psychological trauma and mental health complaints, leading to unique issues related to identifying, prognosticating, and managing IPV-BI outcomes. The goal of this review is to identify important gaps in research and clinical practice in IPV-BI and suggest potential solutions to address them. We summarize IPV research in five key priority areas: (1) unique considerations for IPV-BI study design; (2) understanding non-fatal strangulation as a form of BI; (3) identifying objective biomarkers of IPV-BI; (4) consideration of the chronicity, cumulative and late effects of IPV-BI; and (5) BI as a risk factor for IPV engagement. Our review concludes with a call to action to help investigators develop ecologically valid research studies addressing the identified clinical-research knowledge gaps and strategies to improve care in individuals exposed to IPV-BI. By reducing the current gaps and answering these calls to action, we will approach IPV-BI in a trauma-informed manner, ultimately improving outcomes and quality of life for those impacted by IPV-BI.

Exposure to Adverse Childhood Experiences Predicts Increased Neurobehavioral Symptom Reporting in Adults with Mild Traumatic Brain Injury

The objective of this study was to understand whether exposure to adverse childhood experiences (ACEs) before 18 years of age predicts increased neurobehavioral symptom reporting in adults presenting for treatment secondary to persistent symptoms after mild traumatic brain injury (mTBI). This cross-sectional study identified 78 individuals with mTBI from 2014 to 2018 presenting for treatment to an outpatient multidisciplinary rehabilitation clinic. Neurobehavioral symptom inventory (NSI-22) scores were collected on admission, and ACEs for each patient were abstracted by medical record review. A linear regression model was used to assess if an individual who experienced at least one ACE before age 18 resulted in significantly different neurobehavioral scores compared with those not reporting any history of an ACE before age 18. Participants who reported at least one ACE before age 18 had significantly increased NSI-22 scores on admission to the rehabilitation clinic compared with patients without history of ACEs (mean difference 10.1, p = 0.011), adjusted for age and gender. For individuals presenting for treatment after mTBI, a history of ACEs before age 18 was associated with increased neurobehavioral symptoms.

Intimate Partner Violence and Alexithymia: Do Emotions Matter? A Systematic Review and Meta-Analysis

Intimate partner violence (IPV) encompasses physical, sexual, or psychological abuse. Recent evidence suggests that victims and perpetrators might share some common psychological characteristics. Particularly, high levels of alexithymia, a difficulty in identifying and expressing emotions, and an externally oriented thinking style were found in both victims and perpetrators when compared to the general population. This systematic review and meta-analysis aimed to quantify the levels of alexithymia in victims and perpetrators of IPV and compare these levels to controls. We systematically searched PubMed, PsycINFO, Web of Science, and Scopus databases, using the following strings: ("intimate partner violence" OR "IPV" OR "partner abuse") AND ("alexithymia" OR "alexithymic"). The inclusion criteria were: adult perpetrators or victims of IPV; with or without a rehabilitation program; having or not a comparison group from the general population; alexithymia as outcome; all types of study design. Seventeen studies met the inclusion criteria. Data were meta-analyzed with random-effects models. Results showed comparable levels of alexithymia in victims and perpetrators of IPV (mean = 55.92 vs. 55.15, respectively). Furthermore, we found increased alexithymia in victims (Hedges' g, 0.87 [95% CI 0.43, 1.31]) and perpetrators (Hedges' g, 0.94 [95% CI 0.77, 1.12]) compared to controls. These results highlight that both perpetrators and victims exhibited high levels of alexithymia. A deeper understanding of this psychological dimension can help professionals to plan better-tailored interventions, in which all relevant factors associated with IPV are considered.

A Four-Country Study of Strangulation-Related Alterations in Consciousness in Women Who Have Experienced Intimate Partner Violence: Co-Occurrence with Traumatic Brain Injuries and Measures of Psychological Distress

At least one in three women experience intimate partner violence (IPV) in their lifetime. The most commonly sustained IPV-related brain injuries include strangulation-related alterations in consciousness (S-AICs) and traumatic brain injuries (TBIs). Moreover, survivors of IPV-related S-AICs and/or TBIs often demonstrate psychological distress such as depression, anxiety, and post-traumatic stress. However, the co-occurrence of S-AICs and TBIs, and whether such TBIs may be moderate to severe, has not been systematically examined, and most data have been collected from women in North America. The purpose of this study was to examine the co-occurrence of IPV-related S-AICs and TBIs across a range of geographical locations and to determine the extent to which these S-AICs are related to psychological distress. Women who had experienced physical IPV (n = 213) were included in this secondary analysis of retrospectively collected data across four countries (Canada, the United States, Spain, and Colombia). The Brain Injury Severity Assessment (BISA) was used to assess IPV-related BI across all sites. Because various questionnaires were employed to assess levels of depression, anxiety, and post-traumatic stress disorder at each site, we created a standardized composite score by converting raw scores into Z-scores for analysis. Mann-Whitney U tests and chi-square tests were conducted to examine differences between women with and without experience of S-AICs and to discover if there was a relationship between the occurrence of S-AICs and TBIs. Analysis of variance and analysis of covariance (to control for the potential confounding effects of age, education, and non IPV-related TBI) were used to compare levels of psychological distress in women who had or had not experienced S-AICs. Approximately, 67% of women sustained at least one IPV-related BI (i.e., TBI and/or S-AIC). In a subsample of women who sustained at least one IPV-related BI, approximately 37% sustained both S-AICs and TBIs, 2% sustained only S-AICs (with no TBIs), and 61% sustained TBIs exclusively (with no S-AICs). Furthermore, women who had sustained S-AICs (with or without a TBI) were more likely to have experienced a moderate-to-severe BI than those who had not sustained an S-AIC (BISA severity subscale: U = 3939, p = 0.006). In addition, women who experienced S-AICs (with or without a TBI) reported higher levels of psychological distress compared with women who never experienced S-AICs, irrespective of whether they occurred once or multiple times. These data underscore the importance of assessing for S-AIC in women who have experienced IPV and when present, to also assess for TBIs and the presence of psychological distress. Unfortunately, there were methodological differences across sites precluding cross-site comparisons. Nonetheless, data were collected across four culturally and geographically diverse countries and, therefore, highlight IPV-related BIs as a global issue that needs to be aggressively studied with policies established and then implemented to address findings.

Emotional Clarity and Psychopathology in Women Who Have Experienced Physical Intimate Partner Violence

Intimate partner violence (IPV) is a chronic, traumatic stressor related to posttraumatic stress (PTS), depression, and anxiety. As psychological symptoms are exacerbated in those with poor emotional clarity, the present study evaluates the relationship between emotional clarity and PTS, dissociation, depression, and worry in women who experienced at least one instance of physical IPV (n = 88). Hierarchical regression analyses, controlling for childhood trauma, IPV abuse severity, and IPV-related brain injury, found that lack of emotional clarity was significantly related to greater PTS, dissociative experiences, depression, and worry. Results suggest that emotional clarity may be a relevant therapeutic target for individuals with a history of IPV and psychological distress.

Post-Concussion Symptoms in Women With Head Injury Due to Intimate Partner Violence

Limited research has examined the symptom sequelae of head injuries in women survivors of intimate partner violence (IPV), despite this community being at increased risk for neurotrauma due to partner abuse. The current study compared post-concussion symptom severity between women with and without IPV-related head injuries. Women were recruited from court jurisdictions in Kentucky, USA, after receiving a protective order for partner abuse. The sample included 268 women with no prior head injuries (age: M[standard deviation (SD)] = 31.8[9.8], 77.2% White) and 251 women with lifetime IPV-related head injuries (age: M[SD] = 31.8[9.8], 88.0% White). Women with IPV-related head injuries were slightly older (t = 2.46, p = 0.014) with lower education (χ2 = 5.81, p = 0.016), were more frequently unemployed (χ2 = 9.23, p = 0.002), and had a higher likelihood of residing in a rural setting (χ2 = 30.16, p < 0.001). Women with IPV-related head injuries were also more often White (χ2 = 10.47, p = 0.001), but this group difference was almost entirely related to rural versus urban residence. Women with IPV-related head injuries reported a higher severity of lifetime physical IPV (t = 7.27, p < 0.001, d = 0.64, 95% confidence interval [CI]: [.46, .82]) and sexual IPV (t = 4.65, p < 0.001, d = 0.41 [0.24, 0.59]). A three-factor model of post-concussion symptoms, inclusive of cognitive, physical, and emotional symptoms, fit well (χ2 = 368.99, p < 0.0001, comparative fit index [CFI] = 0.974, Tucker-Lewis index [TLI] = 0.968, root mean square error of approximation [RMSEA] = 0.079 [0.071, 0.087]), and showed evidence for strong measurement invariance across women with and without IPV-related head injuries. The subscale and total scores each had acceptable reliability: cognitive (ω = 0.88 [0.86, 0.90]), physical (ω = 0.74 [0.70, 0.77]), and emotional (ω = 0.88 [0.86, 0.89]), and total score (ω = 0.93 [0.92, 0.95]). Women with IPV-related head injuries reported all individual post-concussion symptoms at a significantly higher frequency, with medium group differences in cognitive (t = 7.57, p < 0.001, d = 0.67 [0.50, 0.85]) and physical symptoms (t = 7.73, p < 0.001, d = 0.68 [0.51, 0.86]) and large group differences in emotional (t = 8.51, p < 0.001, d = 0.75 [0.57, 0.93]) and total symptoms (t = 9.07, p < 0.001, d = 0.80 [0.62, 0.98]). All sociodemographic characteristics were independently associated with post-concussion symptoms, as were physical IPV (total score: r = 0.28 [0.19, 0.35], p < 0.001) and sexual IPV severity (total score: r = 0.22 [0.13, 0.30], p < 0.001). In hierarchical regression analyses, controlling for sociodemographic characteristics (i.e., age, race/ethnicity, education, unemployment, and rural/urban residence) and physical and sexual IPV severity, IPV-related head injury was independently significant and accounted for significant additional variance when predicting cognitive (ΔR2 = 0.05, p < 0.001), physical (ΔR2 = 0.03, p < 0.001), emotional (ΔR2 = 0.07, p < 0.001), and total symptoms (ΔR2 = 0.06, p < 0.001). Negative-binomial regression resulted in similar findings. This study demonstrates that multiple sociodemographic and IPV history variables are related to post-concussion symptom severity, but IPV-related head injury was independently associated with greater symptom severity. Women with IPV-related head injuries may be at increased risk for unaddressed health problems spanning cognitive, physical, and emotional domains. Future research is needed to psychometrically evaluate assessment instruments for this population and to assess efficacy of interventions to address their unique health care needs.

Intimate Partner Violence and Other Trauma Exposures in Females With Traumatic Brain Injury

We examined whether females with a history of traumatic brain injury (TBI) and intimate partner violence (IPV) have greater exposure to lifetime trauma relative to females with TBI but no IPV history. Further, we assessed the effects of lifetime trauma on psychological outcomes after TBI. Female participants (n = 70; age M [standard deviation-SD] = 50.5 [15.2] years) with TBI (time since injury median [interquartile range -IQR] = 10.2 [5.3-17.8] years) completed a structured assessment of lifetime history of TBI, including an IPV module to query head injuries from physical violence by an intimate partner. We characterized lifetime trauma exposure with the Adverse Childhood Experiences (ACEs) questionnaire and Survey of Exposure to Community Violence (CV). We evaluated psychological functioning with self-report questionnaires of post-traumatic stress disorder (PTSD), depression, and anxiety symptoms. Compared with those with no IPV history (n = 51), participants reporting IPV-related head injuries (n = 19; 27.1%) reported more ACEs (M[SD] IPV: 4.5[2.9]; No IPV: 1.6[1.8], p < 0.001, d = 1.08) and greater CV (IPV: 17.5[8.4]; No IPV: 7.6[6.1], p < .0001, d = 1.26). Within the full sample, ACEs (β = 0.21, 95% confidence interval [CI] = 0.04-0.39) and CV (β = 0.07, 95% CI = 0.01-0.13) predicted worse PTSD symptoms, while IPV alone did not. Exposure to all three sources of trauma (ACEs, CV, and IPV) was associated with worse PTSD symptoms relative to fewer traumas. The results highlight the scope of traumatic exposures among TBI survivors and the importance of considering IPV and other lifetime trauma exposure in assessing and managing TBI. Trauma-informed interventions that are modified for TBI-related impairment may offer improved outcomes in managing psychological symptoms.

Repetitive Head Injury and Cognitive, Physical, and Emotional Symptoms in Women Survivors of Intimate Partner Violence

Many women survivors of intimate partner violence (IPV) experience repetitive head injuries in their lifetime, but limited research has examined the cumulative effects of multiple head injuries on post-concussion symptom severity in this population. This study examined how number of lifetime head injuries and episodes of loss of consciousness (LOC) due to head injuries were related to current cognitive, physical, and emotional symptoms among women survivors of IPV. Cisgender women from Kentucky were recruited following a protective order against an intimate partner, including 268 women with no reported lifetime head injuries and 250 women with one or more IPV-related head injuries (mean [M] = 17.2 head injuries, standard deviation [SD] = 50.5, median [Mdn] = 4, range = 1-515; M = 1.8 LOC episodes, SD = 4.3, Mdn = 1, range = 0-35, respectively). Participants underwent in-person interviews about lifetime physical and sexual IPV history, head injury history, and current cognitive, physical, and emotional symptoms. Sociodemographic characteristics, physical and sexual IPV severity, and current symptom severity were examined in relation to number of head injuries and LOC episodes. A higher number of head injuries was associated with greater age, White race, less than high school education, unemployment, and rural residence. No sociodemographic variables differed based on number of LOC episodes. Greater number of lifetime head injuries and LOC episodes correlated significantly with physical IPV severity (rho = 0.35, p < 0.001; rho = 0.33, p < 0.001, respectively) and sexual IPV severity (rho = 0.22, p < 0.001; rho = 0.19, p = 0.003). Greater number of head injuries and LOC episodes correlated significantly with greater cognitive (rho = 0.33, p < 0.001; rho = 0.23, p < 0.001, respectively), physical (rho = 0.36, p < 0.001; rho = 0.31, p < 0.001), emotional (rho = 0.36, p < 0.001; rho = 0.18, p = 0.004), and total symptom severity (rho = 0.39, p < 0.001; rho = 0.26, p < 0.001). In group comparisons, participant groups stratified by number of head injuries (i.e., 0, 1-3, 4+) differed in total symptom severity (p < 0.001, η2 = 0.15), with greater symptom burden associated with more head injuries. Participants with and without LOC differed in symptom severity: cognitive (p < 0.001, d = 0.45), physical (p < 0.001, d = 0.60), emotional (p = 0.004, d = 0.37), and total symptom severity (p < 0.001, d = 0.53). Group differences between participants with and without LOC remained significant after controlling for sociodemographic variables and IPV severity. There was no cumulative effect of LOC, in that participants with 1 LOC episode did not differ from participants with 2 + LOC episodes (p > 0.05). Based on hierarchical regression analyses, only physical symptoms were independently related to number of head injuries (p = 0.008, ΔR2 = 0.011) and number of LOC episodes (p = 0.014, ΔR2 = 0.021) after controlling for sociodemographic characteristics and IPV severity. Among women survivors of IPV, cumulative head injuries appear related to greater symptom severity. Greater head injury history was independently related to worse physical symptoms (e.g., headaches, dizziness, sleep problems), whereas cognitive and emotional symptoms were, in part, attributable to cumulative physical and emotional trauma due to IPV. Women survivors of IPV with repetitive head injuries have unmet neurobehavioral health needs that may benefit from targeted interventions.

Head Injury Due to Intimate Partner Violence: Injury Characteristics, Subacute Symptoms, and Receipt of Care

Women survivors of intimate partner violence (IPV) have increased risk of repetitive neurotrauma in their lifetime but have received less research focus compared with populations of athletes, veterans, and emergency department patients. The current study examined the importance of IPV as a contextual mechanism of injury, by comparing women survivors of IPV based on whether they experienced a head injury due to IPV or a head injury not due to IPV. The analyses involved archival data from in-person interviews conducted with women who received a protective order against an intimate partner in Kentucky from 2001 to 2004 (n = 641). Women were excluded if they reported no head injury history (n = 268), resulting in two groups compared based on a retrospective cohort design: 255 women with at least one self-reported IPV-related head injury (M = 33.8 ± 9.0 years old, range: 19-65; 87.5% White) and 118 women with self-reported head injuries due to reasons other than IPV (M = 32.2 ± 9.1 years old, range: 18-62; 89.0% White). Participants were compared on injury characteristics, lifetime physical and sexual IPV severity, subacute symptoms of head injury, and receipt of care for head injury. Compared with women with head injuries unrelated to IPV, women with IPV-related head injuries reported a higher number of lifetime head injuries (Mdn[range]: IPV-related = 3[1-515] vs. non-IPV-related = 1[1-13], p < 0.001, r = 0.51) and a higher number of head injuries involving loss of consciousness (Mdn[range]: IPV-related = 1[1-35] vs. non-IPV-related = 1[1-4], p < 0.001, r = 0.27), but lower rates of hospitalization (IPV-related = 56.1% vs. non-IPV-related = 73.7%, p = 0.001, odds ratio [OR] = 2.20 [95% confidence interval (CI): 1.36, 3.55]) and formal rehabilitation (IPV-related = 3.2% vs. non-IPV-related = 9.4%, p = 0.011, OR = 3.18 [1.24, 8.13]) following head injury. Women with IPV-related head injuries had greater lifetime severity of physical IPV (p < 0.001, d = 0.64 [0.41, 0.86]) and sexual IPV (p < 0.001, d = 0.38 [0.16, 0.60]). Women with IPV-related head injuries endorsed all symptoms at greater rates than women with non-IPV-related head injuries (ps < 0.001), including physical (e.g., headaches: OR = 3.15 [1.81, 5.47]; dizziness: OR = 2.65 [1.68, 4.16]), cognitive (e.g., trouble problem solving: OR = 2.66 [1.53, 4.64]; inattention: OR = 2.39 [1.52, 3.78]), and emotional symptoms (e.g., depression: OR = 7.39 [4.48, 12.20]; anxiety: OR = 4.60 [2.82, 7.51]). The total count of symptoms endorsed was higher for women with IPV-related head injury than women with head injuries unrelated to IPV (p < 0.001, d = 0.71 [0.49, 0.94]). When controlling for lifetime physical and sexual IPV, IPV-related head injury was independently associated with symptom count (β = 0.261, p < 0.001) and accounted for additional variance in symptom count (ΔR2 = 0.06, p < 0.001). Among women survivors of IPV, those reporting IPV-related head injuries reported greater subacute symptoms, but a lower likelihood of being hospitalized or receiving rehabilitative care. Women with self-reported IPV-related head injuries represent an underserved population that is often unevaluated following injury and may have many unmet care needs. Future studies should examine persistent symptoms following IPV-related head injuries and interventions that would be most beneficial for this population.

Childhood Trauma Questionnaire-Short Form: Evaluation of Factor Structure and Measurement Invariance

Childhood trauma is known to put individuals at risk for mental and physical challenges later in life. Retrospective assessment of early abuse and neglect is critical for prevention and intervention efforts targeted at reducing the negative impacts of childhood trauma. The Childhood Trauma Questionnaire-Short Form (CTQ-SF) is a widely used measure to assess trauma among adolescents and adults, though there are some inconsistencies with regard to its factor structure and psychometric properties. The purpose of the current study was twofold: (1) to evaluate the hypothesized five-factor structure of CTQ-SF and (2) to test measurement invariance (equivalence) of the instrument across gender and race in a large, nationally representative sample of US adults (N = 863). Confirmatory factor analysis results indicate that the five-factor model fit the data well. The results also show that the five-factor model is generally invariant by gender and racial/ethnic groups and that the form's subscales positively correlate with depression, anxiety, and abnormal inflammatory biomarker activity. Assessment is critical for the advocacy and treatment of individuals who have experienced abuse and neglect as children and adolescents. Our findings suggest that the CTQ-SF is a valuable tool for assessing childhood trauma and can be used in advocacy and treatment efforts.

The Association of Adverse Childhood Experiences with Long-term Mood and Anxiety Disorders After Childhood Traumatic Brain Injury: A Population-based Case-Control Study

OBJECTIVE

To assess the association between ACEs and the development of psychiatric disorders by age 25 among individuals who sustained TBI prior to age 10.

DESIGN

Population-based case-control study.

SETTING

Olmsted County, Minnesota.

PARTICIPANTS

566 individuals (N=566) who sustained a TBI prior to age 10 were identified and classified using a validated TBI classification system. Among these individuals, cases with a subsequent mood or anxiety disorder prior to age 25 were identified through clinical diagnostic codes and manual record review. For each case, a 1:1 matched control was randomly selected from individuals with a pediatric TBI who did not have a mood/anxiety disorder prior to the matched case's mood/anxiety disorder.

INTERVENTIONS

Not applicable MAIN OUTCOME MEASURES: Development of a mood/anxiety disorder.

RESULTS

Among the 114 matched pairs of individuals with a TBI prior to age 10, a subsequent mood/anxiety diagnosis was significantly associated with a history of 10 of 14 ACE categories and with having an ACE score ≥1 (odds ratio 5.17; 95% confidence interval 2.78-9.59).

CONCLUSIONS

This is the first population-based study to the authors' knowledge showing that among children who sustained a TBI prior to age 10, those who experienced ACEs are at increased risk of developing a mood or anxiety disorder.
