A Latent Profile Analysis of Aggression and Victimization Across Relationship Types Among Veterans Who Use Substances

Screening for Intimate Partner Violence Experience and Use in the Veterans Health Administration

Importance

The practice of screening women for intimate partner violence (IPV) in health care settings has been a critical part of responding to this major public health problem. Yet, IPV prevention would be enhanced with detection efforts that extend beyond screening for IPV experiences to identifying those who use violence in relationships as well.

Objective

To determine rates of IPV experiences and use (ie, among perpetrators of IPV) and factors associated with disclosures among adult patients seeking mental health services at the Veterans Health Administration.

Design, Setting, and Participants

This cross-sectional study used electronic medical record data drawn from a quality improvement initiative at 5 Veterans Health Administration medical centers conducted between November 2021 and February 2022 to examine IPV disclosures following concurrent screening for IPV experience and use. Participants included patients engaged in mental health services. Data were analyzed in April and May 2023.

Exposure

Mental health clinicians were trained to screen for IPV experience and use concurrently and instructed to screen all patients encountered through routine mental health care visits during a 3-month period.

Main Outcomes and Measures

Outcomes of interest were past-year prevalence of IPV use and experience, sociodemographic characteristics, and clinical diagnoses among screened patients.

Results

A total of 200 patients were offered IPV screening. Of 155 participants (mean [SD] age, 52.45 [15.65] years; 124 [80.0%] men) with completed screenings, 74 (47.7%) denied past-year IPV experience and use, 76 (49.0%) endorsed past-year IPV experience, and 72 (46.4%) endorsed past-year IPV use, including 67 participants (43.2%) who reported IPV experience and use concurrently; only 9 participants (5.8%) endorsed unidirectional IPV experiences and 5 participants (3.2%) endorsed unidirectional IPV use. Patients who reported past-year IPV experience and use were younger than those who denied IPV (experience: mean difference, -7.34 [95% CI, 2.51-12.17] years; use: mean difference, -7.20 [95% CI, 2.40-12.00] years). Patients with a posttraumatic stress disorder diagnosis were more likely to report IPV use (43 patients [59.7%]) than those without a posttraumatic stress disorder diagnosis (29 patients [40.3%]; odds ratio, 2.14; [95% CI, 1.12-4.06]). No other demographic characteristics or clinical diagnoses were associated with IPV use or experience.

Conclusions and Relevance

In this cross-sectional study of IPV rates and associated factors, screening for IPV found high rates of both IPV experience and use among patients receiving mental health care. These findings highlight the benefit of screening for IPV experience and use concurrently across gender and age. Additionally, the associations found between PTSD and IPV use underscore the importance of strengthening and developing additional targeted treatment for IPV.

Relationships between insomnia and alcohol and cocaine use frequency with aggression among veterans engaged in substance use treatment

BACKGROUND

Veterans with substance use problems have rates of partner and non-partner violence that typically exceed the general population. Sleep problems may exacerbate violence and maintain addictive behaviors in non-veterans, but requires study in veterans. Therefore, we examine the interrelationships between substance use, insomnia, and violence in veterans.

METHODS

Veterans (N = 762) screened for a randomized controlled trial at veterans affairs mental health and substance use clinics. Participants completed modified Conflict Tactics Scales to quantify past-year violence and the Insomnia Symptom Questionnaire to assess sleep disturbance. We evaluated associations between substance use and sleep in predicting the target of aggression (partner or non-partner) and degree of violence (aggression or injury) using binomial logistic regressions.

RESULTS

Half of participants endorsed symptoms suggestive of insomnia, 23.2% endorsed physical aggression toward partners (PA-P) and 33.9% non-partners (PA-NP), and 9.7% endorsed physical injury of partners (PI-P) and 17.6% of non-partners (PI-NP). Regressions revealed significant models for PA-P, PA-NP, and PI-NP, whereas the PI-P model was not significant. PA-P was higher among non-Caucasian race and older veterans. PA-NP was more common in those with insomnia and increased with frequency of cocaine use. Insomnia moderated the relationship between cocaine use and PA-NP; there was a weaker relationship between cocaine use and PA-NP in those with insomnia. PI-NP was more common with higher frequency of alcohol and cocaine use, and in those with insomnia.

CONCLUSIONS

This study finds sleep disturbances are meaningful predictors of violence among veterans with differential relationships with aggression severity, victims, and substance use concurrence.

Extending the ACEs Framework: Examining the Relations Between Childhood Abuse and Later Victimization and Perpetration With College Men

Research has revealed that forms of violence are interconnected, but less work focuses on the interconnection of victimization and perpetration, particularly with men. Subsequently, our understanding of the complexities of violence exposure in men's lives and related policies and treatments remains limited. The present study utilizes a sample of at-risk for violence involvement, college men, to examine the relationships between childhood victimization, adulthood victimization, and adulthood perpetration. Participants are 423 college men receiving course credit who completed a battery of standardized questionnaires via an anonymous web survey. Logistic regression is used. Results indicate that 27% of the men report polyperpetration (two or more types of perpetration), 43.5% report polyvictimization (two or more types of victimization), and 60% report experiencing both forms of victimization and perpetration in the past year. Childhood physical abuse has predictive power for perpetration (psychological aggression and polyperpetration) and victimization (sexual violence, psychological aggression, and polyvictimization) for the men in the past year. Childhood sexual abuse has strong predictive power for perpetration (physical violence, sexual violence, and polyperpetration) and victimization (physical violence and sexual violence) with the men in the past year. Finally, emotional abuse has predictive power for victimization (physical violence and psychological aggression), but not perpetration, for the men in the past year. Developmental psychopathology and the adverse childhood experiences frameworks are used to posit potential pathways explaining the relation between childhood abuse and the overlap between victimization and perpetration in adulthood for men. Implications of this study include the use of trauma-informed models of care with men and expanding the scope of study to examine experiences of both victimization and perpetration, and various types of violence, among men.

Long-Term Drug Misuse Increases the Risk of Cognitive Dysfunctions in Intimate Partner Violence Perpetrators: Key Intervention Targets for Reducing Dropout and Reoffending

Intimate partner violence against women (IPVAW) is a major public health problem, with an important mortality rate in women across the world. In this regard, it has been well-established that drug misuse explains (at least in part) an increased risk of IPVAW perpetration. Even though alcohol is the most widely studied drug underlying IPVAW, other drugs, such as cannabis and cocaine also seem to be significant indicators of this type of violence. Nonetheless, little is known about mediators, such as cognitive domains that facilitate proneness to violence after drug consumption. Therefore, the primary objective of the present study was to compare drug misuse patterns and cognitive performance in a carefully selected sample of IPVAW perpetrators (n = 63) and a group of non-violent men (control group; n = 39). Second, we also aimed to study the association between different patterns of drug misuse and cognitive performance and several facets of IPVAW perpetration (i.e., severity of injuries and type of aggression). Our results revealed that IPVAW perpetrators showed considerably higher levels of sustained drug misuse (alcohol, cannabis, cocaine, and heroin) for years and worse cognitive performance than controls. Moreover, the highest drug misuse sustained over time was related to the worst cognitive performance and the highest IPVAW severity. Finally, alcohol and cocaine seemed to be related to IPVAW and risk of reoffending. Whereas, cannabis, heroin, and MDMA were related to the existence of a previous criminal record (delinquency without violence). Hence, research in this field would help to develop coadjutant treatments and intervention packages to reduce drug misuse in the initial stages, which in turn would reduce cognitive impairments in IPVAW perpetrators. These expected improvements might produce an increase in treatment adherence and a decrease in the risk of future IPVAW reoffending.

Veterans with PTSD and comorbid substance use disorders: Does single versus poly-substance use disorder affect treatment outcomes?

INTRODUCTION

Substance use disorders (SUD) frequently co-occur with posttraumatic stress disorder (PTSD). Little is known, however, about how individuals with a single SUD diagnosis (relating to only one substance) compare to individuals with poly-SUD diagnoses (relating to more than one substance) on substance use and PTSD treatment outcomes. To address this gap in the literature, we utilized data from a larger study investigating a 12-week integrated, exposure-based treatment (i.e., Concurrent Treatment of PTSD and Substance Use Disorders using Prolonged Exposure, or COPE) to examine treatment outcomes by single vs. poly-SUD status.

METHOD

Participants were 54 Veterans (92.6% male, average age = 39.72) categorized as having single SUD (n = 39) or poly-SUD (n = 15). T-tests characterized group differences in baseline demographics and presenting symptomatology. Multilevel models examined differences in treatment trajectories between participants with single vs. poly-SUD.

RESULTS

Groups did not differ on baseline frequency of substance use, PTSD symptoms, or treatment retention; however, individuals with poly-SUD evidenced greater reductions in percent days using substances than individuals with a single SUD, and individuals with a single SUD had greater reductions in PTSD symptoms than individuals with poly-SUD over the course of treatment.

DISCUSSION

The findings from this exploratory study suggest that Veterans with PTSD and co-occurring poly-SUD, as compared to a single-SUD, may experience greater improvement in substance use but less improvement in PTSD symptoms during integrated treatment. Future research should identify ways to enhance treatment outcomes for individuals with poly-SUD, and to better understand mechanisms of change for this population.

A scoping review of military veterans involved in the criminal justice system and their health and healthcare

BACKGROUND

In the criminal justice system, special populations, such as older adults or patients with infectious diseases, have been identified as particularly vulnerable to poor health outcomes. Military veterans involved in the criminal justice system are also a vulnerable population warranting attention because of their unique healthcare needs. This review aims to provide an overview of existing literature on justice-involved veterans' health and healthcare to identify research gaps and inform policy and practice.

METHODS

A systematic search was conducted to identify research articles related to justice-involved veterans' health and healthcare that were published prior to December 2017. Study characteristics including healthcare category, study design, sample size, and funding source were extracted and summarized with the aim of providing an overview of extant literature.

RESULTS

The search strategy initially identified 1830 unique abstracts with 1387 abstracts then excluded. Full-text review of 443 articles was conducted with 252 excluded. There were 191 articles included, most related to veterans' mental health (130/191, 68%) or homelessness (24/191, 13%). Most studies used an observational design (173/191, 91%).

CONCLUSIONS

Knowledge gaps identified from the review provide guidance on future areas of research. Studies on different sociodemographic groups, medical conditions, and the management of multiple conditions and psychosocial challenges are needed. Developing and testing interventions, especially randomized trials, to address justice-involved veterans care needs will help to improve their health and healthcare. Finally, an integrated conceptual framework that draws from diverse disciplines, such as criminology, health services, psychology, and implementation science is needed to inform research, policy and practice focused on justice-involved veterans.

Substance use disorders and PTSD: Examining substance use, PTSD symptoms, and dropout following imaginal exposure

Integrated exposure-based interventions to treat substance use disorders (SUD) and posttraumatic stress disorder (PTSD) may not be widely utilized, in part, because of clinician concerns that such interventions will worsen symptomatology and lead to treatment dropout. In order to address this question, the current pilot study examined whether participants' ratings of craving and distress following imaginal exposure predicted increased substance use, PTSD severity, and treatment dropout. Participants (N = 46) were U.S. military Veterans who met criteria for current SUD and PTSD. Subjective ratings of craving and distress, and past-week substance use and PTSD symptom severity were assessed at each treatment session. Multilevel modeling tested whether lagged ratings of craving and distress predicted the following week's frequency of substance use and PTSD severity. Discrete time survival analysis, using proportional odds Cox ratio, examined whether craving and distress ratings predicted treatment dropout. The findings revealed that neither craving nor distress following imaginal exposure were associated with the following week's substance use or PTSD severity. However, participants with higher craving and distress were more likely to drop out before completing treatment. Future research is needed to develop strategies to increase treatment retention for individuals at-risk for treatment dropout and identify mechanisms that account for the association between in-session ratings of craving and distress and dropout.

Coping and violence perpetration in a residential substance use disorder treatment sample

Background: Individuals in substance use disorder treatment report high rates of violence against partners and non-partners. There is growing interest in integrated coping-oriented treatment approaches for violence and substance use concerns, yet little is known about the relationship between specific coping responses and perpetration of partner and non-partner violence. Objective: This cross-sectional study evaluated relationships between coping responses and partner and non-partner physical assault perpetration in a substance use disorder treatment sample. Methods: Participants included 343 men (76%) and women (24%) who completed self-report survey measures of coping responses, violence perpetration, and substance use as part of screening for a randomized trial. Negative binomial regression was used to examine relationships between coping strategies and partner and non-partner violence perpetration, when accounting for substance use and demographic factors. Results: About one-third of participants reported partner violence perpetration (30%) and non-partner violence perpetration (34%). Frequency of partner violence and non-partner violence were both associated with more use of avoidant and emotion-focused strategies and less use of problem-focused coping in adjusted models. Discussion: Continued research is warranted to determine whether coping-oriented interventions decrease violence among people in substance use disorder treatment.

Binge-drinking and non-partner aggression are associated with gambling among Veterans with recent substance use in VA outpatient treatment

BACKGROUND

Gambling is relatively under-assessed in Veterans Affairs (VA) substance use disorder (SUD) treatment settings, yet shared characteristics with substance addiction suggest the importance of understanding how gambling behaviors present in Veterans seeking SUD care.

METHOD

We evaluated substance use, mental health, and violence-related correlates of past 30-day gambling among 833 Veterans (93% male, M age 48years, 72% Caucasian) seeking treatment in VA outpatient mental health and SUD clinics who completed screening for a randomized clinical trial.

RESULTS

A total of 288 (35%) Veterans reported past 30-day gambling. Among those who gambled, 79% had cravings/urges to gamble, whereas between 20%-27% of gamblers reported perceived relationship, legal, and daily life problems related to gambling, as well as difficulty controlling gambling. A logistic regression analysis revealed that age, recent binge-drinking, and non-partner physical aggression were associated with recent gambling.

CONCLUSIONS

Gambling was associated with binge-drinking and non-partner physical aggression, supporting potential shared characteristics among these behaviors such as impulsivity and risk-taking, which may complicate SUD treatment engagement and effectiveness. Findings support the need to screen for gambling in the VA, and to adapt treatments to include gambling as a potential behavioral target or relapse trigger, particularly among heavy drinking patients.
