Drugs, guns, and violent crime in California

BackgroundThere is evidence linking use of controlled substances with perpetration of interpersonal violence. While the United States constitution protects the right to own a firearm, federal law prohibits firearm purchase and possession by persons believed to be at high risk for violence, including those who use controlled substances unlawfully. MethodsWe report here the results of a 13-year prospective observational study on the risk of violent crime associated with a history of criminal drug charges in a cohort of 79,678 legal purchasers of handguns in California in 2001. The main outcomes were post-purchase charges for any violent crime, violent Crime Index crimes (murder, rape, robbery, aggravated assault), and firearm-related violent crimes. The main exposure of interest was a history of pre-purchase charge(s) for drug-related offenses; we examined as a secondary exposure a history of marijuana-related charges. We estimated adjusted hazard ratios (aHR) with 95 % confidence intervals (CI) using Cox proportional hazards multiple events models. ResultsWe found that legal handgun purchasers in California with a history of drug-related charges, even those with marijuana charges only, had triple the risk of a post-purchase violent crime charge compared to purchasers with no criminal charges (drug charges only: aHR=2.9, 95 % CI 2.2–3.8; marijuana charges only: aHR=3.3, 95 % CI 1.8–6.0). In addition, a criminal history of drug charges only vs. no criminal history was associated with increased risk of one or more violent crime charges after the first post-purchase arrest event (aHR=1.6, 95 % CI 1.2–2.3). ConclusionIt is incumbent on researchers and policy makers to understand the nature and causes of this risk in order to take effective steps towards mitigation.

Campus- and Individual-Level Predictors of Risk for Interpersonal Violence Perpetration

Campus- and Individual-Level Predictors of Risk for Interpersonal Violence Perpetration

Cumulative violence exposures among men who have sex with men living with HIV in India: Psychosocial correlates of HIV care continuum outcomes.

Lifetime exposures to violence among men who have sex with men (MSM) are associated with multiple psychosocial health risks and can affect engagement and outcomes of HIV treatment. This study a) explored relationships between levels of exposures to violence and HIV care continuum outcomes among MSM living with HIV in India, and b) identified psychosocial correlates of HIV care continuum outcomes among MSM living with HIV and those with lifetime cumulative exposures to violence (CVE). CVE referred to exposures to violence in both childhood and adulthood. This cross-sectional analysis used survey data collected between August 2016 and May 2017 from 1763 men who have sex with men living with HIV across 10 cities in India, using respondent-driven sampling. We found that higher levels of violence exposure were significantly associated with lower awareness of HIV positive status, and lower likelihood of initiating antiretroviral therapy. Compared with MSM living with HIV that had no CVE, those with CVE were more likely to report perpetration of interpersonal violence, alcohol misuse, depressive symptoms, and HIV transmission risk behaviors and to have two to four co-occurring psychosocial problems. In multivariable analysis with the subset of MSM with CVE, psychosocial correlates significantly associated with at least one HIV care continuum outcome were HIV transmission risk behaviors, perpetration of interpersonal violence, depression, and alcohol misuse. The findings highlight the need for integrating care for lifetime violence exposures and associated behavioral problems in HIV care settings for men who have sex with men living with HIV in India.

Racial Discrimination and Interpersonal Violence in Asian American Adolescents During the COVID-19 Pandemic

PurposeRacial discrimination targeting Asians in the United States has increased sharply since the COVID-19 pandemic. Despite a well-established link with mental/physical health outcomes, little is known about how racial discrimination relates to interpersonal violence, particularly in adolescents. To address this gap in knowledge, we examined cross-sectional and longitudinal (1-year follow-up) associations between racial discrimination and interpersonal violence perpetration and victimization in Asian American adolescents in a large US city. MethodsData from Waves 3 (2020) and 4 (2021) of a randomized clinical trial of a school-based violence prevention program were examined. We limited our sample to participants who identified as Asian American (n = 344; 48.3% female; Meanage = 14.6 years at Wave 3). ResultsAt Wave 3, 26.5% of the adolescents reported experiencing some form of racial discrimination, including 18.3% experiencing verbal harassment due to race and 16.0% reporting inequitable treatment due to race. Relative to their nonvictimized counterparts, adolescents who experienced racial discrimination were more likely to report being a victim of bullying and teen dating violence cross-sectionally and being a bullying victim longitudinally. Moreover, those who experienced racial discrimination reported more bullying and teen dating violence perpetration concurrently, as well as more dating violence perpetration 1 year later. DiscussionIn the understudied population of Asian American adolescents, we found that experiencing racial discrimination contributes to both interpersonal violence victimization and perpetration. Youth violence prevention could include strategies addressing racial discrimination.

Associations between sleep and circadian disruption in shift work and perpetration of interpersonal violence

Research has uncovered substantial consequences of shift work on health outcomes through disruption of sleep and circadian rhythms. Less explored is how the effects of shift work on sleep and circadian rhythms can facilitate interpersonal aggression and violence within the home (i.e., intimate partner violence, child abuse). Given challenges in direct studies on this topic, integration across related literature is critical. In this narrative review, we identify compounding variables centered around sleep and circadian rhythms that place shift workers at an increased risk of perpetrating interpersonal violence. Shift workers have impaired sleep and altered circadian rhythms. Associated alternations in executive functioning, stress, and alcohol use provide pathways to increase risk for interpersonal violence. A model of interactions facilitating the relationship between shift work and interpersonal violence is proposed to promote prevention efforts and motivate policy change.

Interpersonal and Intimate Violence in Mexican Youth: Drug Use, Depression, Anxiety, and Stress during the COVID-19 Pandemic.

The COVID-19 pandemic may have increased interpersonal and intimate violence, harmful use of alcohol and other drugs (AODs), and mental health problems. This study uses a valid path model to describe relationships between these conditions of young Mexicans during the second year of the pandemic. A sample of 7420 Mexicans ages 18 to 24-two-thirds of whom are women-completed the Life Events Checklist, the Alcohol, Smoking, and Substance Involvement Screening Test, the Major Depressive Episode Checklist, the Generalized Anxiety Scale, and the Post-traumatic Stress Disorder (PTSD) Checklist. Young Mexicans reported higher rates of victimization and perpetration of interpersonal and intimate violence and mental health symptomatology than those noted pre- and in the first year of the pandemic. The harmful use of AOD rates were similar to those reported by adolescents before. The findings suggest asymmetric victimization and perpetration of intimate violence by gender (with women at a higher risk). More men than women have engaged in the harmful use of AODs (except for sedatives, which more women abuse). More women than men were at risk of all mental health conditions. The path model indicates that being a victim of intimate violence predicts the harmful use of tobacco, alcohol, cocaine, and sedatives, depression, anxiety, and specific PTSD symptoms (such as re-experimentation and avoidance symptoms). Being a victim of interpersonal violence resulted in severe PTSD symptoms (including avoidance, negative alterations in cognition-mood, and hyperarousal signs). The harmful use of sedatives predicted depressive symptoms. Men's victimizing intimate violence model contrasted with that of women, which included being the victim of interpersonal violence and severe PTSD symptoms. The high school youth model had three paths: victimizing intimate violence, victimizing interpersonal abuse, and sedative use, which predicted depression. Our findings could serve as the basis for future studies exploring the mechanisms that predict violence to develop cost-effective preventive programs and public policies and to address mental health conditions during community emergencies.

Precipitating Circumstances Associated With Intimate Partner Problem–Related Suicides

In 2020, suicide was the 12th leading cause of death among adults in the U.S. Previous research has shown that one common precipitating circumstance among adult suicide decedents is experiencing intimate partner problems (IPPs), such as divorce, separation, romantic break-ups, arguments, conflicts, and intimate partner violence. This study examines how precipitating factors differ between IPP- and non-IPP-related suicides. In 2022, this study analyzed National Violent Death Reporting System data from adult suicide decedents in 48 states and 2 territories between 2003 and 2020. Multivariable logistic regression models were used to compare precipitating circumstances between IPP- and non-IPP-related suicides, controlling for sociodemographic characteristics. Of the 402,391 suicides, 20% (n=80,717) were known to be IPP-related. Circumstances that significantly increased the odds of IPP-related suicides included a history of suicidal thoughts and attempts and mental health problems (depressed mood, alcohol problem, mental health diagnosis), life stressors (interpersonal violence perpetration and victimization, arguments, financial problems, job problems, family problems), and recent legal problems. Non-IPP-related suicides were more likely to occur among older individuals and to be precipitated by a physical health problem or crime. The findings can inform prevention strategies that build resiliency and problem-solving skills, strengthen economic support, and identify and assist people at risk for IPP-related suicides. The Centers for Disease Control and Prevention's Suicide Resource for Action and Intimate Partner Violence Prevention resource packages highlight the best available evidence for policies, programs, and practices related to preventing suicides and IPP.

A Qualitative Analysis of How Individuals Utilized the Twitter Hashtags #NotOkay and #MeToo to Comment on the Perpetration of Interpersonal Violence

The present study examined how individuals describe the nature of interpersonal violence perpetrated against them using the Twitter hashtags #NotOkay and #MeToo. Iterative qualitative coding of 437 tweets resulted in four major themes (i.e., the nature of violence and tactics utilized, the identity of the perpetrator, the location of the assault, and whether the perpetrator was held accountable). Subthemes nested beneath perpetrator identity included whether the perpetrator was known, as well as perpetrator gender identity. Subthemes nested beneath perpetrator tactic included the presence of multiple perpetrators, whether the assault was a crime of opportunity, engagement in physical aggression, utilization of psychological abuse, perpetration of sexual abuse, substance use at the time of the assault (victim and/or perpetrator), whether the abuse persisted, and whether the perpetrator used a weapon. Findings contradict stereotypes that frame interpersonal violence as a single occurrence committed by a stranger who planned an attack using a weapon.

Association of Schizophrenia Spectrum Disorders and Violence Perpetration in Adults and Adolescents From 15 Countries

Violence perpetration outcomes in individuals with schizophrenia spectrum disorders contribute to morbidity and mortality at a population level, disrupt care, and lead to stigma. To conduct a systematic review and meta-analysis of the risk of perpetrating interpersonal violence in individuals with schizophrenia spectrum disorders compared with general population control individuals. Multiple databases were searched for studies in any language from January 1970 to March 2021 using the terms violen* or homicid* and psychosis or psychoses or psychotic or schizophren* or schizoaffective or delusional and terms for mental disorders. Bibliographies of included articles were hand searched. The study included case-control and cohort studies that allowed risks of interpersonal violence perpetration and/or violent criminality in individuals with schizophrenia spectrum disorders to be compared with a general population group without these disorders. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines and the Meta-analyses of Observational Studies in Epidemiology (MOOSE) proposal. Two reviewers extracted data. Quality was assessed using the Newcastle-Ottawa Quality Assessment Scale. Data were pooled using a random-effects model. The main outcome was violence to others obtained either through official records, self-report and/or collateral-report, or medical file review and included any physical assault, robbery, sexual offenses, illegal threats or intimidation, and arson. The meta-analysis included 24 studies of violence perpetration outcomes in 15 countries over 4 decades (N = 51 309 individuals with schizophrenia spectrum disorders; reported mean age of 21 to 54 years at follow-up; of those studies that reported outcomes separately by sex, there were 19 976 male individuals and 14 275 female individuals). There was an increase in risk of violence perpetration in men with schizophrenia and other psychoses (pooled odds ratio [OR], 4.5; 95% CI, 3.6-5.6) with substantial heterogeneity (I2 = 85%; 95% CI, 77-91). The risk was also elevated in women (pooled OR, 10.2; 95% CI, 7.1-14.6), with substantial heterogeneity (I2 = 66%; 95% CI, 31-83). Odds of perpetrating sexual offenses (OR, 5.1; 95% CI, 3.8-6.8) and homicide (OR, 17.7; 95% CI, 13.9-22.6) were also investigated. Three studies found increased relative risks of arson but data were not pooled for this analysis owing to heterogeneity of outcomes. Absolute risks of violence perpetration in register-based studies were less than 1 in 20 in women with schizophrenia spectrum disorders and less than 1 in 4 in men over a 35-year period. This systematic review and meta-analysis found that the risk of perpetrating violent outcomes was increased in individuals with schizophrenia spectrum disorders compared with community control individuals, which has been confirmed in new population-based longitudinal studies and sibling comparison designs.

Adolescents' Relationships With Important Adults: Exploring This Novel Protective Factor Against Interpersonal Violence Victimization and Perpetration.

Despite the increasing influence of peers during adolescence, adults continue to play a significant role in impacting the lives of adolescents. Adolescents' relationships with caring adults are associated with a host of positive outcomes, including improved psychosocial, educational, and behavioral outcomes, and reduced problem behaviors. However, research has not explored the influence of relationships with caring adults on adolescent interpersonal violence (AIV) risk. The aim of this paper was to examine the associations between the presence of an important adult (i.e., an adult youth can go to if they need help with a problem or decision) and youth reports of AIV victimization and perpetration. Participants included 2,173 youth (53.5% female, 76.0% White) in grades 7-10 who participated in a multiple baseline study of a youth-led sexual violence prevention project. Data from the second baseline survey were used to conduct eight binary logistic regression models to test the association between the presence of an important adult and each of the victimization and perpetration types (i.e., any, bullying, sexual harassment, sexual and dating violence). Results showed that youth who reported having an important adult reported significantly lower likelihood of reporting any victimization and perpetration, bullying victimization and perpetration, and harassment victimization and perpetration. There were no significant associations between the presence of an important adult and sexual and dating violence victimization and perpetration. Given the potential for relationships with important adults to protect against some forms of AIV victimization and perpetration, prevention strategies should include connecting youth with important, caring adults and training such adults to help promote attitudinal and behavior shifts that foster AIV prevention.

Factors associated with the perpetration of interpersonal violence and abuse in young people’s intimate relationships

ABSTRACT This paper examines individual, peer and societal factors associated with young people’s instigation of physical, sexual and emotional abuse, including abuse and control through new technologies, in their intimate relationships. The mixed-method research included a survey of 4564 young people aged 14–17 across five European countries. Young people's advisory groups were convened in each country to work alongside the research teams. Across the European sample, 38% of boys and 45% of girls stated they engaged in some form of emotional violence, 10% of girls and 6% of boys reported the use of physical violence and 20% of boys and 4% of girls reported using sexual violence (pressure and/or physical force). A range of intersecting factors, including wider experiences of violence and abuse, gendered attitudes and consumption of online pornography, were associated with the use of intimate violence, although these differed by gender. The research provides new European insights through measuring the association with three discrete forms of IPVA as well as exploring perpetration by both males and females. A Prevention and intervention programmes seeking to respond to violence in young people’s relationships need to develop effective strategies to address the interplay of these factors across young people’s lives.

"Mtoto Wa Nyoka Ni Nyoka," The Child of a Snake is a Snake: A Narrative Analysis of Adverse Childhood Experiences and Perpetration of Interpersonal Violence Among Men in Dar es Salaam, Tanzania.

Childhood exposure to adversity, including abuse and neglect, is consistently found to be a predictor of intimate partner violence (IPV) and peer violence (PV) perpetration in adulthood. The purpose of this study is to qualitatively examine factors that may facilitate or impede the use of violence among those who have been exposed to adversity early in life. We are particularly interested in protective experiences or environments for these participants. The qualitative data were analyzed through thematic coding and narrative analysis of participant life histories.We found three salient themes: (a) parental acceptance and early attachment is protective for coping with stress with intimate partners in adulthood; (b) certain key life turning points can provide a protective context against violent behavior in adulthood; and (c) poverty in adulthood compromises one’s ability to cope with stress and anger in adulthood.Our findings contextualize the different factors that may affect the behavior of perpetration of interpersonal violence among high-risk men in Dar es Salaam who have been exposed to adversity in childhood. These findings provide important information on the risk and protective factors for interpersonal violence spanning from childhood to adulthood. This study highlights the importance of child development interventions in this situation, both for the primary prevention of child adversity and for promoting resilience and mitigating the effects of childhood adversity that put men at risk for perpetration of interpersonal violence in adulthood.

Deployment Experiences and Suicidal Behaviors Related to Interpersonal Violence Perpetration Among Army National Guard Soldiers.

An issue of major policy interest in the U.S. military has been interpersonal violence (IPV), especially relative to the frequent and lengthy deployments of U.S. service members to Iraq and Afghanistan. Lacking, however, are estimates of perpetrators of IPV, in particular, for reservists who have been 30% of the ground combat force. In the present study, Army National Guard soldiers (N = 4,567 in 50 company-sized units) responded to questions about deployment and combat, IPV, and suicidal behaviors. Over a tenth (12.2%) of the soldiers reported having done any aggressive behaviors toward significant others or children during postdeployment. More lengthy and repeated deployments were associated with perpetration of IPV. Having killed or wounded someone and having experienced some form of combat trauma were much more strongly associated with IPV perpetration. Suicidal behaviors were associated with having committed IPV, with the greatest risk associated with suicide attempts. Findings are discussed in terms of underlying mechanisms of both IPV perpetration and suicidal behaviors.

Risk factors for male perpetration of intimate partner violence: A review

Despite the growing body of evidence on IPV perpetration, most have focused on interventions for women and on screening and referral strategies by physicians and other non-physician primary health care workers. The objective of this paper is a review of the literature on male perpetration of intimate partner violence. The databases of PubMed, Science Direct, Google Scholar, and Psychology and Behavioral Sciences were searched for the years of 1980 up to August 30, 2020. 135 articles were screened, and 87 articles were reviewed based on a modified PRISMA method. Common risk factors for both the perpetration of IPV and male interpersonal violence include substance abuse; growing up in a violent home/witnessing violence at an early age; gendered motivations to aggressive behavior, socioeconomic norms and conditioning; and access to firearms. Intimate partner violence is a complex interplay of individual, community based, social and policy factors. Determining the risk factors for male perpetration of IPV may influence screening and referral strategies among physicians and non-physician health care workers with a special emphasis on males in adolescence and into adulthood.

Who Are the Mavens of Bystander Intervention? Implications for the Social Diffusion of Intervention Norms.

A recent randomized controlled trial reported that Green Dot (GD)-a bystander intervention training program that targets popular opinion leaders for intensive training-reduced school-level interpersonal violence perpetration and victimization. Expanding GD's targeted group members to include "mavens" of bystander intervention-those who spread bystander intervention norms to others by communicating with peers-may increase the effectiveness of such training. Self-report data collected from students at the 13 intervention high schools in Kentucky are analyzed to identify characteristics of those who engage in discussions with peers about preventing interpersonal violence. Findings show that students who engage in more frequent bystander behaviors are more likely to have such conversations with peers, but GD participants were no more likely than nonparticipants to discuss preventing interpersonal violence with peers.

Deny, Attack, and Reverse Victim and Offender (DARVO): What Is the Influence on Perceived Perpetrator and Victim Credibility?

ABSTRACT Perpetrators of interpersonal violence sometimes use denial, engage in personal attacks on victim credibility, and assume a victimized role (Deny, Attack, Reverse Victim and Offender; DARVO) to deflect blame. Two new experimental vignette studies were conducted to investigate DARVO. Experiment 1 (316 university students) aimed to assess the effects of a perpetrator’s use of DARVO on perceptions of perpetrator and victim credibility, responsibility, and abusiveness. Participants who were exposed to DARVO perceived the victim to be less believable, more responsible for the violence, and more abusive; DARVO also led participants to judge the perpetrator as less abusive and less responsible. Experiment 2 (360 university students) examined whether learning about DARVO could mitigate its effects on individuals’ perceptions of perpetrators and victims. Results from Experiment 2 indicate that DARVO-educated participants perceived the victim as less abusive and more believable, and rated the perpetrator as less believable. These experiments show DARVO effectively reinforces the distrust of victims’ narratives, but education can reduce some of its power. We suggest that more research and education about this perpetrator tactic is needed to combat its anti-victim effects.
