RESUMO
This study, using a longitudinal design, attempted to identify whether self-reported problems with violence were empirically associated with future violent behavior among Iraq and Afghanistan war veterans and whether and how collateral informant interviews enhanced the risk assessment process. Data were gathered from N = 300 participants (n = 150 dyads of Iraq and Afghanistan war veterans and family/friends). The veterans completed baseline and follow-up interviews 3 years later on average, and family/friends provided collateral data on dependent measures at follow-up. Analyses showed that aggression toward others at follow-up was associated with younger age, posttraumatic stress disorder, combat exposure, and a history of having witnessed parental violence growing up. Self-reported problems controlling violence at baseline had robust statistical power in predicting aggression toward others at follow-up. Collateral report enhanced detection of dependent variables: 20% of cases positive for violence toward others would have been missed relying only on self-report. The results identify a subset of Iraq and Afghanistan war veterans at higher risk for problematic postdeployment adjustment and indicate that the veterans' self-report of violence was useful in predicting future aggression. Underreporting of violence was not evidenced by most veterans but could be improved upon by obtaining collateral information.

Research has yet to examine the relationship between financial well-being and community reintegration of veterans. To address this, we analyzed data from n = 1,388 Iraq and Afghanistan War Era Veterans who completed a national survey on postdeployment adjustment. The results indicated that probable major depressive disorder, posttraumatic stress disorder, and traumatic brain injury were associated with financial difficulties. However, regardless of diagnosis, veterans who reported having money to cover basic needs were significantly less likely to have postdeployment adjustment problems such as criminal arrest, homelessness, substance abuse, suicidal behavior, and aggression. Statistical analyses also indicated that poor money management (e.g., incurring significant debt or writing bad checks) was related to maladjustment, even among veterans at higher income levels. Given these findings, efforts aimed at enhancing financial literacy and promoting meaningful employment may have promise to enhance outcomes and improve quality of life among returning veterans.

Objective: COMT rs4680 (Val158Met) genotype moderates the effect of cannabis on the age of onset of psychosis (AoP). We investigated the association between rs4680 and AoP, after adjusting for relevant covariates, in a Canadian Caucasian sample. Methods: One hundred and sixty-nine subjects with psychosis were recruited. AoP, defined as age of DSM-IV diagnosis was established using the Structured Clinical Interview for DSM-IV. Cannabis use data were collected using a self-report computerized questionnaire. DNA was extracted from saliva and genotyping of the COMT Val158Met polymorphism was done by SNaPshot and TaqMan assays. Kaplan-Meier analysis results are reported. Results: In those who had used cannabis before 20 years of age, rs4680 had a trend level effect on AoP (median AoP: Val/Val < Val/Met < Met/Met 19.37, 20.95, 21.24 years, respectively; log-rank test p = .051). Conclusion: Our data are indicative of the need to further investigate the association between the COMT rs4680 variant and AoP in the context of adolescent cannabis use.

Although a subset of Iraq and Afghanistan Veterans show aggression toward others after they return home from military service, little is known about protective mechanisms that could be bolstered to prevent violence. A national longitudinal survey was conducted between 2009 and 2011 using a random sample of veterans who served in Operation Iraqi Freedom or Operation Enduring Freedom. One thousand and ninety veterans, from 50 states representing all military branches, completed 2 waves of data collection, 1 year apart (retention rate = 79%). The final sample resembled the U.S. military post 9/11 in terms of age, sex, ethnicity, geography, and service branch. Protective mechanisms in socioeconomic (money to cover basic needs, stable employment), psychosocial (resilience, perceiving control over one's life, social support), and physical (healthy sleep, no physical pain) domains were examined. We found these protective mechanisms predicted decreased aggression and violence at follow-up, particularly among higher risk veterans. Multivariable analyses confirmed that protective mechanisms lowered violence through their interaction with risk factors. This study identifies protective mechanisms related to decreased community violence in veterans and indicates that rehabilitation aimed at improving socioeconomic, psychosocial, and physical well-being has potential promise to reduce aggression and violence among veterans after returning home from military service.

This is an examination of the extent to which patients who are violent in the hospital can be distinguished from nonviolent patients, based on information that is readily available at the time of admission to a state acute psychiatric hospital. The charts of 235 inpatients were examined retrospectively, by selecting 103 patients who had engaged in inpatient violence and comparing them with 132 randomly selected patients who had not during the same period. Data were gathered from initial psychiatric assessment and admissions face sheets in patients' charts, reflecting information available to a mental health professional within the first 24 hours of a patient's admission. Multivariate analysis showed that violent and nonviolent patients were distinguished by diagnosis, age, gender, estimated intelligence, psychiatric history, employment history, living situation, and agitated behavior. These factors led to an 80 percent correct classification of violent patients and thus may assist clinicians to structure decision-making about the risk of inpatient violence.

OBJECTIVE: Although criminal behavior in veterans has been cited as a growing problem, little is known about why some veterans are at increased risk for arrest. Theories of criminal behavior postulate that people who have been exposed to stressful environments or traumatic events and who report negative affect such as anger and irritability are at increased risk of antisocial conduct. METHOD: We hypothesized veterans with posttraumatic stress disorder (PTSD) or traumatic brain injury (TBI) who report anger/irritability would show higher rates of criminal arrests. To test this, we examined data in a national survey of N = 1,388 Iraq and Afghanistan war era veterans. RESULTS: We found that 9% of respondents reported arrests since returning home from military service. Most arrests were associated with nonviolent criminal behavior resulting in incarceration for less than 2 weeks. Unadjusted bivariate analyses revealed that veterans with probable PTSD or TBI who reported anger/irritability were more likely to be arrested than were other veterans. In multivariate analyses, arrests were found to be significantly related to younger age, male gender, having witnessed family violence, prior history of arrest, alcohol/drug misuse, and PTSD with high anger/irritability but were not significantly related to combat exposure or TBI. CONCLUSIONS: Findings show that a subset of veterans with PTSD and negative affect may be at increased risk of criminal arrest. Because arrests were more strongly linked to substance abuse and criminal history, clinicians should also consider non-PTSD factors when evaluating and treating veterans with criminal justice involvement.

OBJECTIVE: After returning home, a subset of Iraq and Afghanistan War veterans report engaging in aggression toward others. This study is the first to identify variables empirically related to decreased risk of community violence among veterans. METHOD: The authors conducted a national survey from July 2009 to April 2010 in which participants were randomly drawn from over 1 million US military service members who served after September 11, 2001. Data were collected from a total of 1,388 Iraq and Afghanistan War era and theater veterans. The final sample included veterans from all 50 states and all military branches. RESULTS: One-third of survey respondents self-identified committing an act of aggression toward others during the past year, mostly involving minor aggressive behavior. Younger age, criminal arrest record, combat exposure, probable posttraumatic stress disorder, and alcohol misuse were positively related to violence toward others. Controlling for these covariates, multivariate analyses showed that stable living situation and the perception of having control over one's life were associated with reduced odds of severe violence (R2 = 0.24, χ27 = 145.03, P < .0001). Greater resilience, perceiving positive social support, and having money to cover basic needs were linked to reduced odds of other physical aggression (R2 = 0.20, χ28 = 188.27, P < .0001). CONCLUSIONS: The study identifies aggression as a problem for a subset of Iraq and Afghanistan War veterans who endorsed few protective factors. Analyses revealed that protective factors added incremental value to statistical modeling of violence, even when controlling for robust risk factors. The data indicate that, in addition to clinical interventions directed at treating mental health and substance abuse problems, psychosocial rehabilitation approaches aimed at improving domains of basic functioning and psychological well-being may also be effective in modifying risk and reducing violence among veterans.
