Nonsuicidal self-injury among veterans is associated with psychosocial impairment, suicidal thoughts and behaviors, and underutilization of mental health services.

Nonsuicidal self-injury (NSSI) is a robust predictor of suicide attempts. However, understanding of NSSI and associated treatment utilization among Veterans is limited. Although impairment may be assumed, few studies examine the association between NSSI and psychosocial functioning, a core component of the rehabilitation framework of mental health. In a national survey of Veterans, current NSSI (n = 88) was associated with higher rates of suicidal thoughts and behaviors and more severe psychosocial impairment after adjusting for demographics and probable diagnoses of posttraumatic stress disorder, major depressive disorder, and alcohol use disorder, compared to Veterans without NSSI (n = 979). Only half of Veterans with NSSI were engaged with mental health services, with few appointments attended, suggesting that these Veterans are not receiving treatment interventions. Results underscore the adverse outcomes associated with NSSI. Underutilization of mental health services highlights the importance of screening for NSSI among Veterans to improve psychosocial outcomes.

Physical Function Assessment of Older Veterans With Serious Mental Illness.

OBJECTIVE: To characterize the physical function of older veterans with serious mental illness (SMI) across endurance, strength, and mobility domains. DESIGN: Retrospective analysis of clinical performance data. SETTING: Gerofit program, a national outpatient supervised exercise program for older veterans, delivered in Veterans Health Administration sites. PARTICIPANTS: Older veterans aged 60 and older (n = 166 with SMI, n = 1,441 without SMI) enrolled across eight national Gerofit sites between 2010 and 2019. MEASUREMENTS: Performance measures of physical function covering endurance (6-minute walk test), strength (chair stands, arm curls), and mobility (10-m walk, 8-foot-up-and-go), were administered at Gerofit enrollment. Baseline data from these measures were analyzed to characterize the functional profiles of older veterans with SMI. One sample t tests were examined to compare functional performance of older veterans with SMI to age- and sex-based reference scores. Propensity score matching (1:3) and linear mixed effects models were used to evaluate differences in function between veterans with and without SMI. RESULTS: Older veterans with SMI performed worse on all measures of function (chair stands, arm curls, 10-m walk, 6-minute walk test, 8-foot-up-and-go) compared to age- and sex-based reference scores with statistically significant differences present in the male sample. Functional performance of those with SMI was also worse compared to propensity-score matched older veterans without SMI with statistically significant differences on chair stands, 6-minute walk test, and 10-m walk. CONCLUSION: Older veterans with SMI have compromised strength, mobility, and endurance. Physical function should be a core component of screening and treatment for this population.

The prevalence of traumatic brain injury (TBI) among people impacted by the criminal legal system: An updated meta-analysis and subgroup analyses.

OBJECTIVE: Traumatic brain injury (TBI) is a significant public health concern and has implications for people directly impacted by the criminal legal system during arrest, conviction, incarceration, and community supervision. This meta-analysis estimated the lifetime prevalence of TBI among people supervised by the criminal legal system across settings. HYPOTHESES: Building on previous research, we hypothesized that prevalence estimates would be impacted by methodological, clinical, and demographic factors. METHOD: Eligible studies included those with adult participants supervised by the criminal legal system (i.e., prison, jail, probation, parole, inpatient/forensic hospital) and that provided sample TBI prevalence and method of ascertaining TBI history. We employed subgroup analyses and metaregression to investigate the effects of setting, TBI definition and method of detection, lifetime history of mental illness and substance use disorders, and gender. RESULTS: The sample ultimately included 64 studies totaling 52,540 participants. Using a random-effects model and logit transformation, we found that the overall estimate of TBI prevalence was 45.8% (95% confidence interval, CI [37.8, 54.1], 95% prediction interval, PI [5.5, 92.5]) across all studies and 32.0% (95% CI [25.0, 39.8], 95% PI [11.2, 63.6]) for moderate-to-severe TBI. Significant effects were found for TBI definition and method of detection on the pooled estimate. CONCLUSIONS: The prevalence of TBI among people impacted by the criminal legal system may be larger than in the general population. However, despite recent and ongoing progress in this area of study, the reliability of prevalence estimates remains limited by methodological factors related to TBI definitions and detection methods. Implications for TBI research and clinical service provision are discussed. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

Prevalence and characteristics associated with firearm ownership among low-income U.S. veterans.

This study examined the prevalence of firearm ownership among low-income U.S. military veterans and associated sociodemographic, trauma, and clinical characteristics. Data were analyzed from a nationally representative study of low-income U.S. veterans conducted in 2021 (n = 1,004). Hierarchical logistic regression analyses identified characteristics associated with firearm ownership and mental health correlates of firearm ownership. The results revealed 41.7% of low-income U.S. veterans (95% confidence interval [CI] = 38.7-44.8%) reported owning firearms in their household. Controlling for other factors, firearms owners were significantly more likely to be male and living in their own house. There were no significant associations between trauma exposure (history of assault, unwanted social contact, death of close friend/family, homelessness) or mental health characteristics (history of bipolar disorder, suicide attempt, drug use problems) with firearm ownership. In conclusion, two of five low-income U.S. veterans own a firearm; the prevalence of firearm ownership is higher among men and homeowners. Targeted research on these key segments of the U.S. veteran population and ways to mitigate their firearm misuse may be needed.

Criminal legal involvement among recently separated veterans: Findings from the LIMBIC study.

OBJECTIVE: This study investigated individual-level and neighborhood-level predictors of criminal legal involvement of veterans during the critical transition period from military to civilian life. HYPOTHESES: We hypothesized that substance use, mental health, and personality disorders will increase the incidence of criminal legal involvement, which will be highest among veterans living in socioeconomically disadvantaged neighborhoods after military discharge. METHOD: We analyzed data from a longitudinal cohort study of 418,624 veterans who entered Department of Veterans Affairs (VA) health care after leaving the military. Department of Defense (DoD) data on clinical diagnoses, demographics, and military history were linked to VA data on neighborhood of residence and criminal legal involvement. RESULTS: Criminal legal involvement in the 2 years following military discharge was most strongly predicted by younger age, substance use disorder, and being male. Other predictors included the military branch in which veterans served, deployment history, traumatic brain injury, serious mental illness, personality disorder, having fewer physical health conditions, and living in socioeconomically disadvantaged neighborhoods. These factors combined in multivariable analysis yielded a very large effect size for predicting criminal legal involvement after military separation (area under the curve = .82). The incidence of criminal legal involvement was 10 times higher among veterans with co-occurring substance use disorder, serious mental illness, and personality disorder than among veterans with none of these diagnoses, and these rates were highest among veterans residing in more socioeconomically disadvantaged neighborhoods. CONCLUSIONS: To our knowledge, this is the largest longitudinal study of risk factors for criminal legal involvement in veterans following military discharge. The findings supported the hypothesis that veterans with co-occurring mental disorders living in socioeconomically disadvantaged neighborhoods were at higher risk of criminal legal involvement, underscoring the complex interplay of individual-level and neighborhood-level risk factors for criminal legal involvement after veterans leave the military. These results can inform policy and programs, such as the DoD Transition Assistance Program (TAP) and the VA Military to Civilian Readiness Pathway program (M2C Ready), to enhance community reintegration and prevent criminal legal involvement among veterans transitioning from military to civilian life.

Evictions and tenant-landlord relationships during the 2020-2021 eviction moratorium in the US.

This study provisionally examined the effects of the US eviction moratorium instituted in response to the Coronavirus Disease 2019 (COVID-19) pandemic. Three waves of data collected May 2020-April 2021 from a nationally representative sample of middle- and low-income US tenants (n = 3393 in Wave 1, n = 1311 in Wave 2, and 814 in Wave 3) were analyzed. Across three waves, 4.3% of tenants reported experiencing an eviction during the moratorium and 6%-23% of tenants reported delaying paying rent because of the moratorium. Multivariable analyses found that tenants who delayed paying their rent, were female, or had a history of mental illness or substance use disorder were more likely to report the eviction moratorium had a negative effect on their landlord relationship. COVID-19 infection was not predictive of eviction but tenants with a history of homelessness were more than nine times as likely to report an eviction than those without such a history. Together, these findings suggest the eviction moratorium may have had some unintended consequences on rent payments and tenant-landlord relationships that need to be considered with the end of the federal eviction moratorium.

Correlates of Incarceration History Among Military Veterans.

Veterans with histories of incarceration are at greater risk for poor physical and mental health outcomes, yet prior research in this population has focused on specific subsets of veterans or a narrow range of predictors. We utilized the Bronfenbrenner Socioecological Model as the framework to evaluate correlates of incarceration history in a large sample of Iraq and Afghanistan-era veterans at four levels: demographic, historical, clinical, and contextual. Participants were 2,904 veterans (76.9% male; 49.5% White and 46.5% Black; mean age 38.08, SD = 10.33), 700 of whom reported a history of incarceration. Four logistic regression models predicting history of incarceration were tested, adding demographic, historical, clinical, and contextual variables hierarchically. In the final model, younger age (OR=0.99, 95% CI=0.98-1.00), male gender (OR of being female =0.28, 95% CI=0.21-0.38), belonging to a historically marginalized group (OR of being White =0.69, 95% CI=0.56-0.84), family history of incarceration (OR=1.47, 95% CI=1.10-1.94), adult interpersonal trauma (OR=1.39, 95% CI=1.28-1.51), problematic alcohol use (OR=1.03, 95% CI=1.02-1.05), drug abuse (OR=1.15, 95% CI=1.11-1.19), and unemployment (OR for being employed=0.76, 95% CI=0.62-0.92) were significantly associated with a history of incarceration. Implications of these findings for developing interventions and supporting systems to effectively target this high-risk population of veterans are discussed.

Development and validation of the Durham Risk Score for estimating suicide attempt risk: A prospective cohort analysis.

BACKGROUND: Worldwide, nearly 800,000 individuals die by suicide each year; however, longitudinal prediction of suicide attempts remains a major challenge within the field of psychiatry. The objective of the present research was to develop and evaluate an evidence-based suicide attempt risk checklist [i.e., the Durham Risk Score (DRS)] to aid clinicians in the identification of individuals at risk for attempting suicide in the future. METHODS AND FINDINGS: Three prospective cohort studies, including a population-based study from the United States [i.e., the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) study] as well as 2 smaller US veteran cohorts [i.e., the Assessing and Reducing Post-Deployment Violence Risk (REHAB) and the Veterans After-Discharge Longitudinal Registry (VALOR) studies], were used to develop and validate the DRS. From a total sample size of 35,654 participants, 17,630 participants were selected to develop the checklist, whereas the remaining participants (N = 18,024) were used to validate it. The main outcome measure was future suicide attempts (i.e., actual suicide attempts that occurred after the baseline assessment during the 1- to 3-year follow-up period). Measure development began with a review of the extant literature to identify potential variables that had substantial empirical support as longitudinal predictors of suicide attempts and deaths. Next, receiver operating characteristic (ROC) curve analysis was utilized to identify variables from the literature review that uniquely contributed to the longitudinal prediction of suicide attempts in the development cohorts. We observed that the DRS was a robust prospective predictor of future suicide attempts in both the combined development (area under the curve [AUC] = 0.91) and validation (AUC = 0.92) cohorts. A concentration of risk analysis found that across all 35,654 participants, 82% of prospective suicide attempts occurred among individuals in the top 15% of DRS scores, whereas 27% occurred in the top 1%. The DRS also performed well among important subgroups, including women (AUC = 0.91), men (AUC = 0.93), Black (AUC = 0.92), White (AUC = 0.93), Hispanic (AUC = 0.89), veterans (AUC = 0.91), lower-income individuals (AUC = 0.90), younger adults (AUC = 0.88), and lesbian, gay, bisexual, transgender, and queer or questioning (LGBTQ) individuals (AUC = 0.88). The primary limitation of the present study was its its reliance on secondary data analyses to develop and validate the risk score. CONCLUSIONS: In this study, we observed that the DRS was a strong predictor of future suicide attempts in both the combined development (AUC = 0.91) and validation (AUC = 0.92) cohorts. It also demonstrated good utility in many important subgroups, including women, men, Black, White, Hispanic, veterans, lower-income individuals, younger adults, and LGBTQ individuals. We further observed that 82% of prospective suicide attempts occurred among individuals in the top 15% of DRS scores, whereas 27% occurred in the top 1%. Taken together, these findings suggest that the DRS represents a significant advancement in suicide risk prediction over traditional clinical assessment approaches. While more work is needed to independently validate the DRS in prospective studies and to identify the optimal methods to assess the constructs used to calculate the score, our findings suggest that the DRS is a promising new tool that has the potential to significantly enhance clinicians' ability to identify individuals at risk for attempting suicide in the future.

Financial Strain, Mental Illness, and Homelessness: Results From a National Longitudinal Study.

BACKGROUND: Research indicates that adults with severe mental illness have lower income and employment than adults without severe mental illness. Further, mental illness has been identified as a risk factor for homelessness. However, little research has investigated the interrelationships between financial strain, mental illness, and homelessness. It is unknown whether or to what extent financial strain mediates the association between mental illness and subsequent homelessness. METHODS: This study examined financial strain and severe mental illness (psychotic, bipolar, and depressive disorders in the past 12 months) as predictors of subsequent homelessness and financial strain as a mediator of the link between severe mental illness and homelessness by analyzing data from waves 1 and 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (n=34,653). RESULTS: χ2 and multivariable analyses revealed that financial crises and debt, lower income, unemployment, and past homelessness at wave 1 each significantly predicted subsequent homelessness between waves 1 and 2. For participants with and without severe mental illness, risk of homelessness between waves 1 and 2 increased as a function of the number of financial strain variables at wave 1. Mediation analyses showed a direct effect of severe mental illness on future homelessness as well as an indirect effect via greater financial strain, which accounted for 39% of the link between mental illness and homelessness. CONCLUSIONS: The findings showing that financial strain mediated the association between severe mental illness and homelessness support assessment of financial well-being in the context of treatment of mental illness and homeless service programs. The results suggest that individuals experiencing homelessness who have severe mental illness may benefit from assistance increasing financial literacy, improving money management, and achieving financial well-being.

Suicidal ideation and thoughts of self-harm during the COVID-19 pandemic: The role of COVID-19-related stress, social isolation, and financial strain.

BACKGROUND: There are significant concerns about mental health problems occurring due to the coronavirus disease 2019 (COVID-19) pandemic. To date, there has been limited empirical investigation about thoughts of suicide and self-harm during the COVID-19 pandemic. METHODS: A national survey was conducted May 2020 to investigate the association between mental health symptoms, social isolation, and financial stressors during the COVID-19 pandemic and thoughts of suicide and self-harm. A total of 6607 US adults completed an online survey; survey criteria included an age minimum of 22 years old and reported annual gross income of $75,000 or below. Statistical raking procedures were conducted to more precisely weight the sample using US Census data on age, geographic region, sex, race, and ethnicity. RESULTS: COVID-19-related stress symptoms, loneliness, and financial strain were associated with thoughts of suicide/self-harm in multivariable logistic regression analyses, as were younger age, being a military veteran, past homelessness, lifetime severe mental illness, current depressive symptoms, alcohol misuse, and having tested positive for COVID-19. Greater social support was inversely related to thoughts of suicide/self-harm whereas running out of money for basic needs (e.g., food), housing instability (e.g., delaying rent), and filing for unemployment or disability were positively related. CONCLUSIONS: Public health interventions to decrease risk of suicide and self-harm in the wake of the COVID-19 pandemic should address pandemic-related stress, social isolation, and financial strain experienced including food insecurity, job loss, and risk of eviction/homelessness.

Mobile Neurofeedback for Pain Management in Veterans with TBI and PTSD.

OBJECTIVE: Chronic pain is common in military veterans with traumatic brain injury (TBI) and post-traumatic stress disorder (PTSD). Neurofeedback, or electroencephalograph (EEG) biofeedback, has been associated with lower pain but requires frequent travel to a clinic. The current study examined feasibility and explored effectiveness of neurofeedback delivered with a portable EEG headset linked to an application on a mobile device. DESIGN: Open-label, single-arm clinical trial. SETTING: Home, outside of clinic. SUBJECTS: N = 41 veterans with chronic pain, TBI, and PTSD. METHOD: Veterans were instructed to perform "mobile neurofeedback" on their own for three months. Clinical research staff conducted two home visits and two phone calls to provide technical assistance and troubleshoot difficulties. RESULTS: N = 36 veterans returned for follow-up at three months (88% retention). During this time, subjects completed a mean of 33.09 neurofeedback sessions (10 minutes each). Analyses revealed that veterans reported lower pain intensity, pain interference, depression, PTSD symptoms, anger, sleep disturbance, and suicidal ideation after the three-month intervention compared with baseline. Comparing pain ratings before and after individual neurofeedback sessions, veterans reported reduced pain intensity 67% of the time immediately following mobile neurofeedback. There were no serious adverse events reported. CONCLUSIONS: This preliminary study found that veterans with chronic pain, TBI, and PTSD were able to use neurofeedback with mobile devices independently after modest training and support. While a double-blind randomized controlled trial is needed for confirmation, the results show promise of a portable, technology-based neuromodulatory approach for pain management with minimal side effects.

Drinking to Cope with Posttraumatic Stress: A Nationally Representative Study of Men with and without Military Combat Experience.

OBJECTIVE: Posttraumatic stress disorder (PTSD) and hazardous alcohol use are prevalent among trauma survivors. Despite higher rates of both PTSD and hazardous alcohol use among military combat veterans than civilians, scant research has examined whether military combat experience is associated with drinking alcohol to cope with PTSD symptoms. This study tested the hypothesis that compared to trauma-exposed men without combat experience, men with military combat experience would be more likely to endorse drinking alcohol to cope with their PTSD symptoms. Methods: Interview data from N = 11,474 men who reported at least one lifetime traumatic experience were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a face-to-face interview study that recruited a nationally representative sample of adults living in the United States between 2004 and 2005. Results: Among men endorsing lifetime trauma exposure, men with military combat experience (n = 1,386) were more likely than men without combat experience (n = 10,088) to report drinking alcohol to cope (7.22 vs. 2.61% in unweighted analyses, 6.46 vs. 2.37% in weighted analyses). Total number of lifetime trauma types, lifetime PTSD severity, and lifetime alcohol abuse/dependence were significantly associated with drinking to cope in bivariate and multivariate analyses. Military combat experience was significantly associated with drinking to cope in multivariate analyses adjusting for lifetime PTSD diagnosis. Military combat experience was not significantly associated with drinking to cope in multivariate analyses adjusting for lifetime PTSD symptom count. Conclusions: Although military combat experience was significantly associated with drinking to cope in bivariate analyses, multivariate analyses yielded mixed findings: combat experience was significantly associated with drinking to cope in models adjusting for PTSD diagnosis, but not in models adjusting for PTSD symptom count. Findings highlight the importance of assessing and targeting PTSD symptom-related alcohol use, even in the absence of alcohol abuse/dependence. Results from this preliminary study could inform future research on drinking to cope with PTSD symptoms among military combat veterans and other trauma survivors.

Financial Strain and Suicide Attempts in a Nationally Representative Sample of US Adults.

Although research has identified many suicide risk factors, the relationship between financial strain and suicide has received less attention. Using data representative of the US adult population (n = 34,653) from wave 1 (2001-2002) and wave 2 (2004-2005) of the National Epidemiologic Survey on Alcohol and Related Conditions, we investigated the association between financial strain-financial debt/crisis, unemployment, past homelessness, and lower income-and subsequent suicide attempts and suicidal ideation. Multivariable logistic regression controlling for demographic and clinical covariates showed that cumulative financial strain was predictive of suicide attempts between waves 1 and 2 (odds ratio (OR) = 1.53, 95% confidence interval (CI): 1.32, 1.77). Wave 1 financial debt/crisis (OR = 1.58, 95% CI: 1.06, 2.34), unemployment (OR = 1.52, 95% CI: 1.10, 2.10), past homelessness (OR = 1.50, 95% CI: 1.03, 2.17), and lower income (OR = 1.51, 95% CI: 1.01, 2.25) were each associated with subsequent suicide attempts. Respondents endorsing these 4 financial-strain variables had 20 times higher predicted probability of attempting suicide compared with respondents endorsing none of these variables. Analyses yielded similar results examining suicidal ideation. Financial strain accumulated from multiple sources (debt, housing instability, unemployment, and low income) should be considered for optimal assessment, management, and prevention of suicide.

Religion, spirituality, and suicide risk in Iraq and Afghanistan era veterans.

BACKGROUND: United States military veterans experience disproportionate rates of suicide relative to the general population. Evidence suggests religion and spirituality may impact suicide risk, but less is known about which religious/spiritual factors are most salient. The present study sought to identify the religious/spiritual factors most associated with the likelihood of having experienced suicidal ideation and attempting suicide in a sample of recent veterans. METHODS: Data were collected from 1002 Iraq/Afghanistan-era veterans (Mage = 37.68; 79.6% male; 54.1% non-Hispanic White) enrolled in the ongoing Veterans Affairs Mid-Atlantic Mental Illness Research, Education and Clinical Center multi-site Study of Post-Deployment Mental Health. RESULTS: In multiple regression models with stepwise deletion (p < .05), after controlling for depression and posttraumatic stress disorder (PTSD) diagnoses, independent variables that demonstrated a significant effect on suicidal ideation were perceived lack of control and problems with self-forgiveness. After controlling for age, PTSD diagnosis, and substance use problems, independent variables that demonstrated a significant effect on suicide attempt history were perceived as punishment by God and lack of meaning/purpose. CONCLUSIONS: Clinical screening for spiritual difficulties may improve detection of suicidality risk factors and refine treatment planning. Collaboration with spiritual care providers, such as chaplains, may enhance suicide prevention efforts.

Using Interpretation Bias Modification to Reduce Anger in Veterans with Posttraumatic Stress Disorder: A Pilot Study.

Difficulty controlling anger is the most commonly reported reintegration concern among veterans with posttraumatic stress disorder (PTSD). One of the mechanisms associated with problematic anger is a tendency to interpret ambiguous interpersonal situations as hostile, known as the hostile interpretation bias (HIB). A computer-based interpretation bias modification (IBM) intervention has been shown to successfully reduce HIB and anger but has not been tested in veterans with PTSD. The current study was a pilot trial of this IBM intervention modified to address problematic anger among veterans with PTSD. Veterans with PTSD and a high level of anger (N = 7) completed eight sessions of IBM treatment over the course of 4 weeks. Participants completed self-report questionnaires at pre- and posttreatment assessment visits, as well as a treatment acceptability interview at posttreatment. Veterans experienced large reductions in hostile interpretation bias and anger from pre- to posttreatment, ds = 1.03-1.96, although these estimates may be unstable due to the small sample size. The feasibility for recruitment, retention, and treatment completion were high. Questionnaire and interview data demonstrated that most participants were satisfied with the treatment and found it helpful and easy to use. Overall, IBM for anger was feasible and acceptable to veterans with PTSD and was associated with reductions in hostile interpretations and self-reported anger outcomes. Further research examining this approach is warranted.

Cognitive Rehabilitation With Mobile Technology and Social Support for Veterans With TBI and PTSD: A Randomized Clinical Trial.

OBJECTIVE: To investigate effects of cognitive rehabilitation with mobile technology and social support on veterans with traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD). PARTICIPANTS: There were 112 dyads, comprised by a veteran and a family member or friend (224 participants in total). DESIGN: Dyads were randomized to the following: (1) a novel intervention, Cognitive Applications for Life Management (CALM), involving goal management training plus mobile devices for cueing and training attentional control; or (2) Brain Health Training, involving psychoeducation plus mobile devices to train visual memory. MAIN MEASURES: Executive dysfunction (disinhibition, impulsivity) and emotional dysregulation (anger, maladaptive interpersonal behaviors) collected prior to randomization and following intervention completion at 6 months. RESULTS: The clinical trial yielded negative findings regarding executive dysfunction but positive findings on measures of emotion dysregulation. Veterans randomized to CALM reported a 25% decrease in anger over 6 months compared with 8% reduction in the control (B = -5.27, P = .008). Family/friends reported that veterans randomized to CALM engaged in 26% fewer maladaptive interpersonal behaviors (eg, aggression) over 6 months compared with 6% reduction in the control (B = -2.08, P = .016). An unanticipated result was clinically meaningful change in reduced PTSD symptoms among veterans randomized to CALM (P < .001). CONCLUSION: This preliminary study demonstrated effectiveness of CALM for reducing emotional dysregulation in veterans with TBI and PTSD.

Neuropsychological correlates of self-reported impulsivity and informant-reported maladaptive behaviour among veterans with posttraumatic stress disorder and traumatic brain injury history.

OBJECTIVE: Frontal lobe deficits resulting from traumatic brain injury (TBI) and/or posttraumatic stress disorder (PTSD) have been linked to impulsive behaviour. We sought to examine whether neuropsychological performance predicted self-reported impulsivity and informant-reported maladaptive behaviour. METHOD: We administered the Delis-Kaplan Executive Function System (D-KEFS) to 116 Iraq/Afghanistan-era veterans diagnosed with a history of TBI and PTSD. RESULTS: Poorer performance on D-KEFS Stroop Task (both colour and word, separately) and Trail making (letter sequencing and motor speed) tasks and higher PTSD symptom severity were associated with higher self-reported impulsivity. Trail making letter sequencing performance was negatively associated with informant-reported maladaptive behaviour. Regression analyses revealed PTSD symptom severity and Trail making letter sequencing best predicted self-reported impulsivity, even when accounting for age, sex, and education. Only Trail making letter sequencing predicted informant-reported maladaptive behaviour when accounting for other variables in the model. CONCLUSIONS: Attention and processing speed impairments and PTSD symptom severity appear to be important predictors of impulsivity and problematic behaviour among veterans. Findings have implications for theoretical models of aggression and violence and inform the assessment and treatment of individuals with TBI and PTSD.

Traumatic Brain Injury in Iraq and Afghanistan Veterans: New Results From a National Random Sample Study.

This study randomly sampled post-9/11 military veterans and reports on causes, predictors, and frequency of traumatic brain injury (TBI) (N=1,388). A total of 17.3% met criteria for TBI during military service, with about one-half reporting multiple head injuries, which were related to higher rates of posttraumatic stress disorder, depression, back pain, and suicidal ideation. The most common mechanisms of TBI included blasts (33.1%), objects hitting head (31.7%), and fall (13.5%). TBI was associated with enlisted rank, male gender, high combat exposure, and sustaining TBI prior to military service. Clinical and research efforts in veterans should consider TBI mechanism, effects of cumulative TBI, and screening for premilitary TBI.

Self-Reported Pain in Male and Female Iraq/Afghanistan-Era Veterans: Associations with Psychiatric Symptoms and Functioning.

OBJECTIVE: To examine pain symptoms and co-occurring psychiatric and functional indices in male and female Iraq/Afghanistan-era veterans. DESIGN: Self-reported data collection and interviews of Iraq/Afghanistan-era veterans who participated in a multisite study of postdeployment mental health. SETTING: Veterans were enrolled at one of four participating VA sites. SUBJECTS: Two thousand five hundred eighty-seven male and 662 female Iraq/Afghanistan-era veterans. METHODS: Nonparametric Wilcoxon rank tests examined differences in pain scores between male and female veterans. Chi-square tests assessed differences between male and female veterans in the proportion of respondents endorsing moderate to high levels of pain vs no pain. Multilevel regression analyses evaluated the effect of pain on a variety of psychiatric and functional measures. RESULTS: Compared with males, female veterans reported significantly higher mean levels of headache ( P < 0.0001), muscle soreness ( P < 0.008), and total pain ( P < 0.0001), and were more likely to report the highest levels of headache ( P < 0.0001) and muscle soreness ( P < 0.0039). The presence of pain symptoms in Iraq/Afghanistan-era veterans was positively associated with psychiatric comorbidity and negatively associated with psychosocial functioning. There were no observed gender differences in psychiatric and functional indices when levels of pain were equated. CONCLUSIONS: Although female Iraq/Afghanistan-era veterans reported higher levels of pain than male veterans overall, male and female veterans experienced similar levels of psychiatric and functional problems at equivalent levels of reported pain. These findings suggest that pain-associated psychological and functional impacts are comparable and consequential for both male and female veterans.

An Investigation of Treatment Engagement Among Returning Veterans With Problematic Anger.

Anger is a commonly reported problem among returning veterans, yet little attention has been devoted to studying treatment engagement among veterans who report anger problems but do not have posttraumatic stress disorder (PTSD). This study compares Iraq-Afghanistan veterans with anger/no PTSD (n = 159) to others reporting significant PTSD symptoms (n = 285) and those reporting neither anger nor PTSD (n = 716) on rates of treatment utilization, perceived barriers to treatment, and preferences for care. Relative to the PTSD group, the anger/no-PTSD group was significantly less likely to have received mental health treatment in the last year, despite endorsing barriers to treatment at a lower rate. Furthermore, the anger/no-PTSD group endorsed fewer preferences than the PTSD group. Results suggest that the anger/no-PTSD group is a unique subgroup that may be less likely to identify a need for treatment. Implications are discussed.
