Gun- and Non-Gun-Related Violence Exposure and Risk for Subsequent Gun Carrying Among Male Juvenile Offenders

Examining Associations Between School Connectedness, Social Support, Violence, and Firearm Carrying

Firearms are the leading cause of pediatric deaths. Few studies have identified protective factors that reduce the risk of firearm violence. Interpersonal factors, including school connectedness and social support, protect against multiple health-affecting risk behaviors. Therefore, this study examines associations of school connectedness and social support with firearm and weapon violence involvement. Data were gathered through an anonymous survey conducted across 13 high schools within an urban school district in 2018 (n = 2,604) modeled on the Centers for Disease Control and Prevention Youth Risk Behavior Surveillance Survey. Separate hierarchical logistic regression models examined associations between school connectedness and social support, and the outcomes of firearm carrying and engaging in violence with a weapon on school property in the past 12 months. Models were adjusted for age, race, and covariates representing basic needs, education, and mental health. The mean age was 15.7 years, and 57.5% of youth were female. 5.8% of youth had carried firearms and 5.5% engaged in violence with a weapon on school property in the past 12 months. School connectedness was significantly inversely associated with engaging in violence with a weapon on school property (odds ratio [OR] 0.225, 95% confidence interval [CI] [0.080, 0.632] and high levels of social support were significantly inversely associated with firearm carrying (OR 0.522, 95% CI [0.313, 0.870]). School connectedness and social support may be important in protecting youth from firearm and weapon-related violence. Interventions that strengthen safe and supportive interpersonal relationships within school environments and broader support systems across contexts may help reduce firearm and weapon violence involvement.

Exposure to Neighborhood Violence and Gun Carrying Among Adolescents in the United States: Findings From A Population-Based Study

Although studies have investigated and found an association between victimization and weapon carrying, few studies have examined the association between exposure to neighborhood violence (NV) and gun carrying among adolescents. The objective of this study was to examine the cross-sectional association between exposure to NV and gun carrying among adolescents. Data for this study came from the 2021 Youth Risk Behavior Survey. An analytic sample of 17,033 adolescents aged 14 to 18 years old (51.7% male) was analyzed using logistic regression with complementary log-log link function. The outcome variable investigated in this study is gun carrying and was measured as a binary variable, whereas the main explanatory variable examined in this study was exposure to NV, which was also measured as a binary variable. Of the 17,033 adolescents, 4.2% carried a weapon during the past year, and 18.7% were exposed to NV. Controlling for the effects of other factors, adolescents who were exposed to NV had more than double the odds of carrying a gun when compared to their counterparts not exposed to NV (adjusted odds ratio = 2.33, 95% Confidence Intervals [1.69, 3.23]). Other significant factors associated with gun carrying include being a male, non-Hispanic Black, being threatened or injured with a weapon, use of alcohol, cigarette smoking, and misuse of prescription opioids. High parental monitoring was protective against gun carrying. The findings of this study underscore the importance of developing age-appropriate intervention strategies to reduce gun carrying among adolescents. School counselors and other professionals working with adolescents in disadvantaged neighborhoods should actively engage parents in assessments and interventions.

Correlates of dangerous firearm storage among a representative sample of firearm owners across nine states

OBJECTIVE

To identify demographic and behavioral correlates of dangerous firearm storage (i.e., unlocked and loaded) among firearm owners in nine states.

METHODS

Online survey data from the probability-based sample were collected using Ipsos Knowledge Panel. Participants were adults residing in nine states across the United States (n = 7785).

RESULTS

Nearly one third of the firearm owners within the sample stored at least one of their firearms unlocked and loaded. Greater threat sensitivity was associated with dangerous firearm storage. Established firearm owners who purchased an additional firearm during the firearm purchasing surge (2020-2021) had increased odds of storing at least one firearm unlocked and loaded. Those who had direct exposure to firearm violence and those whose primary reason for having a firearm at home was protection also had increased odds of storing at least one firearm unlocked and loaded.

CONCLUSIONS

The results contribute to the literature on firearm storage tendencies, highlighting correlates of dangerous firearm storage within the home related to perceptions of threat and direct experiences with firearm violence. Implications include the need for broad public education on the value of secure storage targeted toward to those who have an elevated perception of danger and have been personally exposed to firearm violence.

Examining the Relation Between Early Violence Exposure and Firearm-Related Experiences in Emerging Adulthood: A Longitudinal Cohort Study

Firearms are a leading cause of death among adolescents and young adults in the United States. Early exposure to violence, as a victim or witness, is associated with increased risk of firearm-related experiences, including carrying and threatening others with a gun. These experiences, in turn, increase the risk of both fatal and non-fatal firearm injuries. Using an ethnically diverse sample of emerging adults, we build on prior research by examining the link between early violence exposure at multiple contexts of the social-ecological model and multiple firearm-related experiences (i.e., firearm-threatening victimization, firearm-threatening perpetration, and firearm carriage). We analyzed data from a 10-year longitudinal study of 1042 youth in the Southern United States. Experiencing childhood physical abuse was associated with both firearm-threatening victimization and perpetration in emerging adulthood. Additionally, exposure to neighborhood and interparental violence were linked to threatening others with firearms and carrying firearms, respectively. Counter to expectations, bullying victimization did not emerge as a predictor of any firearm-related experiences. Findings highlight the importance of cross-cutting violence prevention efforts to prevent high-risk firearm-related behaviors among emerging adults. Programs for children and adolescents that address these types of violence exposure should highlight coping skills and sources of positive social support to bolster protective factors against firearm-related outcomes.

Gun Violence on Walkable Routes to and from School: Recommendations for Policy and Practice

Gun-related violence exposure is a significant public health problem for urban youth. Few studies have implemented methods to estimate the spatial influence of activity spaces on gun violence exposure constrained by the physical configuration of walkable street networks. The present research uses computational network and local indicators of spatial autocorrelation methods to explore gun violence exposure along the walkable streets near schools in Compton, California. Findings demonstrated strong evidence that gun violence is clustered at all distances along the pedestrian network and in proximity to Compton Unified School District (K-12) schools, reaching a maximum between 1.2 and 1.8 mi; thereafter the "attractiveness" of schools to gun violence was inhibiting. Almost all schools had at least one shooting within a 5-min walk (i.e., about 400 m); 37.8% of schools had an average shooting distance of less than 400 m; about 250 incidents occurred within 5 min of schools; and about 30 schools had a shooting within a 5-min walking distance. Determining the spatial extent of violence exposure in proximity to key activity spaces for youth, such as schools, has substantial implications for the health and wellbeing of youth living in violence-prone areas. The public health and legal implications of this study are discussed in context.

Youth Exposure to Gun, Knife, and Physical Assaults: Assessing PTSD Symptoms Across Types of Assaults, Race, Ethnicity, Sex, and Context

This study examined posttraumatic stress disorder (PTSD) symptoms in relation to physical assaults and weapons-related victimization, as well as the moderating roles of demographic characteristics and the context of victimization. The sample consisted of 910 racially and ethnically diverse adolescents and young adults from an urban commuter college in the Northeast U.S. Findings include significant sex differences and racial differences in reported victimization and symptoms. Men reported significantly more physical assaults, gun victimizations, and knife victimizations than women. Black participants reported significantly more gun victimization than all other groups, and Black, White, and Asian participants reported significantly more physical assault experiences than Latinx participants. Individuals victimized by physical assault or by gun victimization were more than twice as likely to report clinically significant PTSD symptoms than individuals without such experiences, even after adjusting for demographic differences. In addition, for gun victimization in the community, a two-way interaction (gun victimization by race) and a three-way interaction (gun victimization by race by sex) were significantly associated with clinically significant PTSD symptoms. Gun victimization in the community, which disproportionately impacts Black men, was the only context in which PTSD symptoms were highest for men compared to women. The overall finding of lower PTSD symptoms among men suggests that clinical practice must include an intentional focus on violence victimization, including the use of weapons, as well as the various ways that distress might manifest among men. In addition to symptoms of PTSD, other symptoms of distress, including substance use, anger, and retaliatory aggression, should be considered. Public policy and public health must also direct attention to the use of weapons in violence victimization and the proliferation of weapons violence.

Exposure to gun violence and handgun carrying from adolescence to adulthood

RATIONALE

While empirical interest in understanding the mental health consequences surrounding gun violence has increased, currently there is much unknown about the long reach of childhood exposure to gun violence on handgun carrying across the life course.

OBJECTIVE

The current study aims to evaluate the relations between witnessing gun violence before age 12 and subsequent handgun-carrying behavior from adolescence to adulthood in a nationally representative sample of U.S. youth.

METHODS

Data from 15 waves from the National Longitudinal Survey of Youth 1997) are analyzed (Ns range from 5695 to 5875 participants). Categorical latent growth curve models are estimated to assess individual differences in handgun-carrying behavior over time and the relationships between childhood exposure to gun violence, initial levels during adolescence, and rates of change from adolescence to adulthood.

RESULTS

Participants who reported witnessing seeing someone shot or shot at in childhood demonstrated higher odds of carrying a handgun in adolescence. Exposure to gun violence was not associated with changes in the odds of handgun carrying from adolescence to adulthood after controlling for theoretically relevant covariates.

CONCLUSIONS

Childhood exposure to gun violence appears to be a risk factor for handgun carrying in adolescence. Nonetheless, other behaviors and demographic characteristics account for inter-individual differences in changes in handgun carrying across the life course.

Identifying Protective Factors That Mitigate Relations Between Experiences with Violence and Gun Carriage for Black Young Adults Living in Economically Marginalized Urban Communities

Gun violence disproportionately impacts Black young adults living in economically marginalized urban communities and results in increased risk for injury and death. This study identifies protective factors across the ecological model for Black young adults experiencing peer-based physical and relational aggression and victimization that can mitigate the likelihood of gun carriage. The sample included 141 Black young adults living in economically marginalized communities who had experienced violence. Regression and moderation analyses indicated (1) peer-based physical and relational aggression and victimization negatively associated with gun carriage, and (2) personal assets, positive outlook, student status, and neighborhood attachment interacted with peer-based violent experiences and had protective associations with gun carriage. Findings from this study indicate a need for tailored prevention, policy efforts in order to support Black young adults and decrease gun carriage.

Ecological promotive and protective factors deterring gun carriage for young adults living in communities with high rates of community violence

This study identified promotive and protective factors that lessened the likelihood of handgun carriage in a sample of 141 predominantly Black (97%) young adults (ages 18-22) living in high burden communities experiencing elevated rates of violence. Participants completed surveys assessing overall risk and protective factors for violence across ecological contexts (e.g., individual/peer, family, school, and community). A series of regression and moderation analyses were conducted to ascertain direct (promotive) and indirect (protective) relations between factors across the ecological model and likelihood of gun carriage. Results indicated that (1) consistent with previous studies, both witnessing violence and violence victimization were significant risk factors for handgun carriage, (2) ethnic identity was a significant promotive factor related to a lower likelihood of handgun carriage, and (3) lack of family conflict, student status, and community assets were significant protective factors where higher levels of these factors attenuated the relation between exposure to community violence and likelihood of gun carriage. This is one of the first strengths-based studies examining factors that may mitigate the likelihood of gun carriage for young adults in high risk contexts. Our findings suggest that gun violence prevention efforts for high burden communities should support young adults by strengthening factors across the ecological model (e.g., individual, family, school, and community).

Firearm-related threat exposure and associated factors among men and women entering a supportive housing substance use disorder recovery program

Background: Exposure to firearm victimization has often been overlooked as a sequela of substance use disorders (SUD).Objectives: The overall objective of this study was to explore firearm-related victimization and associated factors among men and women entering a supportive housing SUD recovery program.Methods: This study used program intake information from men (n = 1,758) and women (n = 1,066) clients entering a SUD recovery program.Results: Results found that almost half (49.3%) of the clients entering the program had ever been threatened with a firearm or held at gunpoint, and one-quarter of those clients had experienced firearm-related threats in the 6 months before entering the program. Economic vulnerability, mental health problems, polysubstance use, interpersonal victimization, and early use of drugs and alcohol were associated with firearm-related threat exposure. Many of the factors associated with firearm-related threat exposure were similar for men and women. Multivariate results found that polysubstance use (OR 1.16 men and 1.13 women), number of adverse childhood events (OR 1.13 men and 1.09 women), and interpersonal victimization (OR 3.41 men and 2.05 women) in the 6 months before program entry were significantly associated with ever being threatened with a firearm. Suicidality (OR 1.53 men and 1.80 women) and interpersonal victimization (OR 6.38 men and 6.08 women) were associated with being threatened with a firearm in the 6 months before program entry for both men and women.Conclusion: Results suggest there is a need for firearm-related risk reduction interventions for individuals in SUD recovery programs.

Examining Recovery Status and Supports before and after Substance Abuse Disorder Treatment Among Clients Who Experienced Lifetime and Recent Firearm-Related Threats

Firearm-related risks have often been overlooked in the sequela of substance use and substance use disorders. This study compares adult substance abuse disorder treatment (SADT) clients who experienced recent ( n = 274) and lifetime ( n = 889) firearm threats to adults who were not threatened with a firearm ( n = 2029) before and 12 months after program entry. More men experienced firearm threats (38.8%) than women (34.2%). However, among those with any firearm threats, more women (27.2%) experienced firearm threats in the year before program entry than men (20.2%). Being threatened with a firearm was associated with increased economic vulnerability, criminal justice system involvement, mental health problems, and victimization both before and after SADT program entry. A higher number of adverse childhood experiences were associated with firearm threats and particularly recent firearm threats. Results of this study underscore the importance of screening for firearm-related risks in substance abuse disorder treatment programs.

The Co-Occurrence of Illegal Gun Carrying and Gun Violence Exposure: Evidence for Practitioners From Young People Adjudicated for Serious Involvement in Crime

We depicted the episodic nature of illegal gun carrying and tested its co-occurrence with gun violence victimization and exposure. We tested differences in differences using data from the Pathways to Desistance Study, originally collected between 2000 and 2010 (Phoenix, Arizona, and Philadelphia, Pennsylvania), on young people adjudicated for serious involvement in crime. We then tested the changes in gun victimization experiences attending gun-carrying changes for this sample. We found gun victimization to be highest during periods of gun carrying, and this correspondence held regardless of future or past gun-carrying behavior. This manifests both in direct victimization and witnessing gun violence. Even among gun carriers, episodes of noncarrying are common, with 76.4% of gun carriers in a 1-year period also reporting a pause in their carrying behavior of at least 6 months. Gun carrying and gun violence exposure co-occur at a high rate. During any period of gun carrying, the carrier has at least a 2% chance of getting shot versus near 0% for periods of noncarrying. Our results suggest that illegal gun carrying is malleable, and public health efforts to reduce the incidence of gun carrying could yield meaningful reductions in violence.

A Within-Individual Examination of the Predictors of Gun Carrying During Adolescence and Young Adulthood Among Young Men

Although prior studies have identified several risk factors for gun carrying, no prior longitudinal studies have examined a comprehensive set of explanatory factors together in within-individual change models or examined whether the predictors of gun carrying change across adolescence and early young adulthood. The present study fills these gaps by examining the predictive utility of several risk factors for gun carrying, and by examining whether any of the associations vary by age. The sample included 1216 young men who were arrested for the first time during adolescence (approximately 15 years old) and interviewed regularly for 5 years (until approximately 20 years old) after the first arrest. The outcome was youth-self-reported gun carrying and the risk factors included several variables consistent with various explanations for gun carrying (psychosocial maturity deficits; antisocial behavioral style; socialization; victimization). Research questions were addressed with fixed effects dynamic panel models (within-individual change models). Results showed that the most robust predictors of gun carrying were increased exposure to guns and gun-related violence and increased engagement in other antisocial and illegal behavior. The results emphasize the specific etiology of gun carrying and the potential social contagion effect of gun-related events. Overall, the study points to the need for prevention and intervention programs to specifically target the reduction of the real and perceived prevalence of gun-related events in young men's lives.

PTSD and Attitudes Toward Guns Following Interpersonal Trauma

Gun violence is a serious public health concern that is currently grossly understudied. Gun attitudes are a potential risk factor for gun violence; however, factors related to gun attitudes have not been identified. Mental illness such as posttraumatic stress disorder (PTSD) is commonly discussed as a key factor in gun violence, despite research lacking in this area, and it is unknown whether symptoms of PTSD and probable PTSD are associated with more positive attitudes toward guns. The aim of the current study was to investigate the relations between PTSD symptoms and gun attitudes among 265 undergraduate students who experienced at least one interpersonal traumatic event (M_age = 24.69 years, SD = 7.15 years, 75.6% female, 61.1% White). Path analysis revealed that individuals with PTSD symptoms above clinical cutoff were not more likely to have more positive gun attitudes. However, the PTSD symptom clusters evinced distinct relations with gun attitudes. Intrusion and avoidance symptoms were related to gun beliefs regarding protection, with intrusion symptoms being linked to a stronger belief that guns provide protection from crime and victimization (β = .23), whereas avoidance symptoms were inversely associated with this belief (β = -.22). Interestingly, neither trauma related in feelings and thoughts nor arousal and reactivity corresponded with gun attitudes. Certain PTSD symptom clusters may be relevant in understanding gun beliefs, with specific symptoms exhibiting distinct ties to gun attitudes.

Risk and Protective Factors for Gun Violence in Male Juvenile Offenders

OBJECTIVE

To examine several risk and protective factors as predictors of future gun violence among male juvenile offenders.

METHOD

Data came from a longitudinal cohort of 1,170 male juvenile offenders (42.1% Black; 34.0% Latino; 19.2% White) ages 14-19 who were adjudicated for a serious offense. Interviews were conducted with participants every 6 months for 3 years and then annually for 4 years. The outcome was self-reported gun violence assessed at each follow-up. The time-lagged predictors included several self-reported risk factors (i.e., gun carrying, non-gun violence, drug dealing, heavy drinking, poor impulse control, rewards for crime, peer gun carrying, peer non-gun delinquency, gang membership) and protective factors (i.e., concern for others, expectations, and aspirations for work/family, religious beliefs, adult social supports). The data were analyzed using generalized estimating equation models.

RESULTS

There were 266 participants who reported engaging in gun violence at one or more assessments. Gun carrying was a significant predictor of future gun violence; however, nearly half (49%) of the juveniles who reported gun carrying across the repeated assessments did not report engaging in gun violence. Besides gun carrying, several risk (i.e., drug dealing, heavy drinking, rewards for crime, gang membership, peer gun carrying) and protective (i.e., concern for others, aspirations for work/family, religious beliefs, adult social supports) factors significantly predicted gun violence, after controlling for their co-occurrence (Risk factor odds ratios = 1.18-1.50; Protective factor odds ratios =.44-.87; ps<.05).

CONCLUSIONS

Interventions designed to prevent gun violence among juvenile offenders should reduce targeted risk factors, while strengthening protective factors that may offset these risks.

Special Section Introduction: Revitalizing Developmental Research on Adolescent Gun Involvement

Although firearm violence is universally recognized as a paramount public health problem in the United States, for nearly two decades a Congressional budget amendment prevented federal agencies from funding research aimed at understanding the antecedents and consequences of gun violence. These restrictions have been lifted in recent years; however, the field is struggling to overcome a considerable lapse in developmentally-informed longitudinal research on adolescent gun involvement. Some key areas in need of further investigation include: (a) examining developmental and gender differences in risk factors for adolescent gun carrying, (b) clarifying the mechanisms through which socio-economic disadvantage confers risk for engaging in adolescent gun violence, (c) identifying proximal risk and protective factors that are associated with engagement in adolescent gun violence among high risk youth, and (d) delineating the unique effect the exposure to gun violence has on adolescents' emotional and behavioral problems. This special section was organized in an attempt to revitalize research on these issues using a diverse array of longitudinal data sets consisting of both epidemiological and juvenile justice samples. Collectively, the findings from these studies are based upon repeated assessments conducted from childhood through early adulthood, making this set of papers uniquely positioned to advance our understanding of adolescent gun involvement from a developmental perspective.

The Direct and Indirect Associations between Childhood Socioeconomic Disadvantage and Adolescent Gun Violence

We examined whether childhood socioeconomic disadvantage was associated with adolescent gun violence and whether early symptoms of conduct disorder and/or exposure to delinquent peers accounted for the linkage. Participants were 503 predominately Black and White boys who were recruited in 1st grade from Pittsburgh public schools. Multi-informant assessments were conducted regularly from approximately ages 7 to 20. A latent socioeconomic disadvantage factor was estimated with census-tract and parent-reported data when boys were about age 7½. Latent growth curve models assessed parent/teacher-reported conduct problems and youth-reported peer delinquency from about ages 7½ to 10. The outcome was youth-reported engagement in gun violence by about age 20. We also controlled for race. Analyses examined whether the association between childhood socioeconomic disadvantage and adolescent gun violence was mediated through early conduct problems and/or increased exposure to delinquent peers. Childhood socioeconomic disadvantage was associated with adolescent gun violence, and some of this effect was mediated through peer delinquency and conduct problems. Specifically, childhood socioeconomic disadvantage was associated with greater affiliation with delinquent peers in early childhood, and early peer delinquency promoted a greater increase in conduct problems across childhood, and these conduct problems, in turn, led to an increased risk for adolescent gun violence. In summary, this study found that early socioeconomic disadvantage was directly and indirectly related to adolescent gun violence. Results suggest that interventions that aim to reduce conduct problems and deviant peer group affiliation in childhood might be important windows of opportunity for reducing gun violence in impoverished neighborhoods.

Addressing Key Gaps in Existing Longitudinal Research and Establishing a Pathway Forward for Firearm Violence Prevention Research

The main purpose of this article and this special section is to encourage greater attention to the key gaps that exist in our understanding of the epidemiology of adolescent firearm violence and to provide a pathway forward for future longitudinal research that will inform prevention efforts. This increased attention is especially salient given: (a) firearms are the leading cause of death for adolescents and emerging adults in the United States, with the majority of these deaths due to interpersonal violence; (b) significant health and social disparities with regards to the populations that are most affected by interpersonal firearm violence have been documented; and, (c) limitations in federal research funding during the past 30 years have created a deficit of knowledge about key risk and protective factors necessary to inform evidence-based prevention efforts. We discuss the implications of the articles in this special edition for existing and novel prevention programs. We also identify key considerations for future epidemiological research, including the need for a greater focus on collecting longitudinal data among nationally representative samples enriched with subgroups of at-risk youth, the need to examine the role of protective factors and mediating variables within existing and novel theoretical models of firearm risk behaviors, the need to examine key factors across all levels of the socio-ecological model, and the need to incorporate novel and innovative research designs, methods and analyses.

Gun Violence Exposure and Experiences of Depression Among Mothers

Gun violence is a uniquely prevalent issue in the USA that disproportionately affects disadvantaged families already at risk of health disparities. Despite the traumatic nature of witnessing gun violence, we have little knowledge of whether exposure to local gun violence is associated with higher risks of depression among mothers, whose symptoms of depression are likely to have spillover effects for kin. We examined the association between exposure to gun violence in mothers' neighborhoods and their experiences of depression using longitudinal Fragile Families and Child Wellbeing Study data (n = 4587) in tandem with lagged outcome and fixed effect models. We find that mothers who witness at least one shooting in their neighborhoods or local communities exhibit more symptoms of depression and are 32-60% more likely to meet criteria for depression than mothers who do not witness a shooting. We also find that witnessing a shooting is associated with increases in parental aggravation, which is partially mediated by maternal depression. Given this and other previously documented spillover effects of mothers' mental health on children and family members, these findings have important implications for mothers' wellbeing and their kin. Further, we observe substantial racial and socioeconomic disparities in exposure to gun violence, suggesting that gun violence may heighten health disparities and drawing attention to the importance of providing mental health resources in communities that are most affected by gun violence.

Exposure to Gun Violence: Associations with Anxiety, Depressive Symptoms, and Aggression among Male Juvenile Offenders

Objective: To examine whether at-risk male youth experience increases in anxiety, depressive symptoms, and aggression during years when they are exposed to gun violence, adjusting for relevant covariates.Method: Participants were 1,216 male, justice-involved adolescents who were recently arrested for the first time for a moderate offense. They were interviewed 9 times over 5 years. Fixed effects (within-individual) regression models were used to estimate concurrent associations between exposure to gun violence and three outcomes: depressive symptoms, anxiety symptoms, and aggression (both overall and separately for proactive and reactive aggression). The reverse direction (anxiety, depressive symptoms, and aggression predicting gun violence exposure) was also modeled.Results: After controlling for covariates, exposure to gun violence was significantly associated with increases in reactive aggression and, to a lesser extent, increases in proactive aggression. In addition, gun violence exposure was associated with increased anxiety but not depressive symptoms. We found no support for the reverse direction.Conclusions: At-risk males experienced significant increases in anxiety and aggression (particularly reactive aggression) during years when they are exposed to gun violence, even after accounting for several potential confounding factors. The greater impact on reactive aggression suggests that exposure to gun violence may affect self-regulation and/or social information processing. The analyses shed light on the less-visible damage wrought by gun violence and underscore the importance of mental health screening and treatment for youth who have been exposed to violence - especially gun violence - both to assist individual youths and to disrupt cycles of violence.

Association of Firearm Access, Use, and Victimization During Adolescence With Firearm Perpetration During Adulthood in a 16-Year Longitudinal Study of Youth Involved in the Juvenile Justice System

IMPORTANCE

Preventing firearm violence requires understanding its antecedents. Yet no comprehensive longitudinal study has examined how involvement with firearms during adolescence-use, access, and victimization (defined as threatened with a weapon or gunshot injury)-is associated with the perpetration of firearm violence in adulthood.

OBJECTIVE

To examine the association between firearm involvement during adolescence and subsequent firearm perpetration and ownership in adulthood among youth involved in the juvenile justice system.

DESIGN, SETTING, AND PARTICIPANTS

This cohort study analyzed interview responses of 1829 randomly selected participants as part of the Northwestern Juvenile Project, a longitudinal study of health needs and outcomes of youth sampled from a temporary juvenile detention center in a large US city. Youth aged 10 to 18 years were interviewed in detention from November 1995 through June 1998. Participants were reinterviewed up to 13 times over 16 years through February 2015, for a total of 17 776 interviews. The sample was stratified by sex, race/ethnicity, age, and legal status (juvenile or adult court). Data were analyzed from April 2017, when data preparation began, through November 2020.

EXPOSURES

Firearm involvement during adolescence: use (ie, threaten, shoot), access (ownership, ease of access, firearm in household, membership in gang that carries firearms), and victimization (gunshot injury, threatened with a weapon).

MAIN OUTCOMES AND MEASURES

Firearm involvement during adulthood: perpetration of firearm violence (ie, threatening with or using a firearm) and firearm ownership.

RESULTS

Among the 1829 participants, 1388 had a 16-year follow-up interview: 860 males, 528 females; 809 were African American, 203 were non-Hispanic White; 374 were Hispanic; and 2 were other race/ethnicity; median (interquartile range) age of 32 (30-32) years. Eighty-five percent of males and 63.2% of females were involved with firearms as adolescents. Compared with females, males had significantly higher odds of every type of involvement except having a firearm in the home. In adulthood, 41.3% of males and 10.5% of females perpetrated firearm violence. Adolescents who had been threatened with a weapon or injured by firearms had 3.1 (95% CI, 2.0-4.9) and 2.4 (95% CI, 1.2-4.9) times the odds of perpetrating violence during adulthood. Similar associations were found for firearm ownership.

CONCLUSIONS AND RELEVANCE

Involvement with firearms during adolescence-including victimization-is a significant risk factor for firearm perpetration and ownership during adulthood.

Drug Dealing and Gun Carrying go Hand in Hand: Examining How Juvenile Offenders' Gun Carrying Changes Before and After Drug Dealing Spells across 84 Months

OBJECTIVES

This study aims to examine whether periods of marijuana and other illicit drug dealing ("spells" of dealing) are associated with changes in young male offenders' gun carrying behavior.

METHODS

This paper uses 84 months of data from a sample of 479 serious juvenile male offenders who were assessed every six months for three years and then annually for four years. At each assessment, participants reported on engagement in illicit behaviors, including drug dealing and gun carrying, in each month since the prior interview. We used fixed effects models to assess within-individual changes in participants' gun carrying immediately before, during, and right after a dealing spell, while controlling for relevant time varying confounds (e.g., gang involvement, exposure to violence). Additionally, we tested moderation by type of drug sold.

RESULTS

There was a slight increase in gun carrying right before a drug dealing spell (OR = 1.3-1.4), then a more pronounced increase in gun carrying during the months of a drug dealing spell (OR = 8.0-12.8). Right after a dealing spell ends, youths' gun carrying dropped dramatically, but remained significantly elevated relative to their baseline levels (OR = 2.6-2.8). The association between drug dealing spells and increases in gun carrying was stronger when participants dealt hard drugs (e.g., cocaine, heroin) relative to marijuana.

CONCLUSIONS

These results suggest that designing and implementing programs to prevent the initiation of drug dealing and decrease involvement in drug dealing may help to substantially reduce illegal gun carrying and firearm violence among delinquent males.

Patterns of adolescent gun carrying and gun-related crime arrests in Indianapolis, Indiana over an 11-year time period

Adolescent males are disproportionately affected by homicide as both victims and offenders. Indianapolis has seen increases in youth homicides over the past few years; gun carrying increases an individual's risk for involvement in firearm violence. It is unclear how often youth are arrested for gun carrying and gun-related crimes. Examining these patterns may identify an opportunity for intervention. This study is a descriptive epidemiology analysis that examines patterns of gun carrying and gun-related crime arrests among justice involved youth in Marion County (Indianapolis), Indiana. We accessed juvenile court records from January 1, 2006 to December 31, 2016 on all individuals arrested for a gun carrying offense (i.e., illegal possession of a firearm or gun; n = 711) and all individuals arrested for a gun-related crime (i.e., homicide, robbery, aggravated assault; n = 150). Data were analyzed in fall 2019. Proportions of juvenile arrests for both gun carrying (47.0 per 1000 arrests) and gun-related crime (25.4 per 1000 arrests) have substantially increased compared to ten-years ago (4.5 per 1000 arrests and 2.0 per 1000 arrests, respectively). Of those arrested, 27.7 per 100,000 population were arrested for a repeated gun-related offense; of which 21.5 per 100,000 were first arrested for gun carrying and 6.2 per 100,000 were arrested for a gun-related crime. The majority of gun-related repeat offenders were first arrested for gun carrying; therefore, these gun-carrying arrests may be an opportunity to intervene on an individual level by providing treatment, other needed resources, and discussing safe firearm storage with families and communities.

Dynamic Risk Factors for Handgun Carrying: Are There Developmental or Sex Differences?

Objective: This study examines the effects of dynamic risk factors on handgun carrying from adolescence into young adulthood.Method: A nationally representative sample of 8,679 individuals (ages 12-26; 51.1% male; 58% White, 26.8% African American; 21.2% Hispanic ethnicity) from the National Longitudinal Survey of Youth (1997 cohort) interviewed at least three times across nine annual waves is used to estimate effects on handgun carrying. Key predictors include gang membership, selling and using drugs, violent crime, and arrest. Using mixed effects models, we focus on within-individual effects across three timeframes from ages 12 to 26: 1) predictors and handgun carrying measured concurrently, 2) predictors measured across one year and handgun carrying measured in the final month of the same year, and 3) predictors measured in the wave before handgun carrying. We also contrast estimates by sex and age.Results: All theoretically relevant predictors statistically significantly predict handgun carrying across the first two timeframes. However, none are statistically significant predictors of handgun carrying in the following year. Few significant sex and age differences emerge.Conclusions: Handgun carrying is an ephemeral behavior particularly during adolescence. The predictors of handgun carrying, which are grounded in gangs, drug use/sale, and crime involvement, appear to have short-term impacts that are consistent across age as well as across sex. Consequently, future work should focus on shorter-term changes in models and there is no evidence that intervention efforts must take fundamentally different approaches to reduce handgun use among males versus females or adolescents versus adults.

Perceived Gun Access and Gun Carrying Among Male Adolescent Offenders

Gun violence takes a significant toll on adolescents in the United States, and there is a lack of longitudinal research on perceptual factors that drive gun carrying. Notably, there is no information on the relationship between perception of gun accessibility and gun carrying. Using data collected between 2000 and 2006 in the Pathways to Desistance Study, we examine the effects of perceived access to guns in a sample of adolescent offenders. A generalized estimating equations approach tested the effect of perceived gun access along with other known risk factors for gun carrying across time. Even after adjusting for these other risk factors, perceived gun access was significantly related to future carrying. Our findings support self-reported gun availability as a significant, population-based risk factor related to gun carrying in high-risk youth. Further research on how perceived access mediates the decision to carry guns would be valuable for formulating effective gun policy.

Initiation Age, Cumulative Prevalence, and Longitudinal Patterns of Handgun Carrying Among Rural Adolescents: A Multistate Study

PURPOSE

Adolescent handgun carrying is a behavioral marker for youth interpersonal conflicts and an intervention point for violence prevention. Our knowledge about the epidemiology of adolescent handgun carrying mainly pertains to urban settings. Evidence on the initiation age, cumulative prevalence, and longitudinal patterns of this behavior and on handgun-related norms and peer behavior among male and female rural adolescents is scant.

METHODS

We used data from the control arm of the Community Youth Development Study, a community-randomized controlled trial of the Communities That Care prevention system. Annually, 1,039 males and 963 females were surveyed from Grade 6 (2005) to age 19 years (2012) in 12 rural towns across seven U.S. states.

RESULTS

In Grade 6, 11.5% of males and 2.8% of females reported past-year handgun carrying. Between Grade 6 and age 19 years, 33.7% of males and 9.6% of females reported handgun carrying at least once. Among participants who ever reported handgun carrying, 34.0% of males and 29.3% of females did so for the first time in Grade 6. Among participants who ever reported handgun carrying, 54.6% of males and 71.7% of females did so only one time over the seven study assessments. Greater proportions of participants who reported handgun carrying than those who did not do so endorsed prohandgun norms and had a peer who carried among both males (Grade 10: prevalence difference = 57%; 95% CI: 46%-67%) and females (Grade 10: prevalence difference = 45%; 95% CI: 12%-78%).

CONCLUSIONS

Rural adolescent handgun carrying is not uncommon and warrants etiologic research for developing culturally appropriate and setting-specific prevention programs.

Rates and correlates of risky firearm behaviors among adolescents and young adults treated in an urban emergency department

Firearm violence is a leading cause of death for urban adolescents and young adults (A/YAs). Little is known about patterns of risky firearm behaviors (RFBs) that may increase firearm-related fatality and non-fatal injury risk. To inform prevention efforts, we examined the rates and correlates of RFBs, including firearm carriage in risky situations (e.g., while drunk/high), discharge in risky situations (e.g., fleeing police), and firearm aggression (e.g., firearm threats/use against a partner/non-partner), among a sample of A/YAs (age-16-29) seeking medical or injury related care (7/2017-6/2018) at a Level-1 urban Emergency Department (ED). In total, 1312 A/YAs completed the survey (mean-age 23.2; 29.6%-male; 50.5%-Black; 56.3%-public assistance), with 102 (7.8%) engaging in RFBs. Among those engaging in RFBs, 42% reported firearm ownership, 68.6% firearm carriage in high-risk situations, 39.2% firearm discharge in risky situations, and 41.2% reported partner/non-partner firearm aggression. Regression identified RFBs correlates, including older age (AOR = 1.09), male sex (AOR = 1.63), Black race/ethnicity (AOR = 2.01), substance misuse (AOR = 2.75), attitudes favoring firearm use/retaliation (AOR = 1.38), peer firearm ownership/carriage (AOR = 3.26), higher levels of community violence exposure (AOR = 1.05), and active parole/probation (AOR 2.38). Higher coping skills were protective for RFBs (AOR = 0.83). Overall, we found that A/YAs seeking urban ED treatment reported elevated RFB rates, emphasizing the need for novel prevention initiatives, especially those incorporating tailored content addressing substance use, retaliatory violence, and peer delinquency/norms, while enhancing self-efficacy for avoiding RFBs and providing access to external resources within a resiliency-based framework. Such prevention approaches may be a critical step towards addressing the public health problem of firearm violence. Primary Funding Sources: NIH/NIDA K23DA039341; NIH/NCATS UL1TR000433.

A scoping review of patterns, motives, and risk and protective factors for adolescent firearm carriage

Firearm carriage is a key risk factor for interpersonal firearm violence, a leading cause of adolescent (age < 18) mortality. However, the epidemiology of adolescent firearm carriage has not been well characterized. This scoping review examined four databases (PubMed; Scopus; EMBASE; Criminal Justice Abstracts) to summarize research on patterns, motives, and underlying risk/protective factors for adolescent firearm carriage. Of 6156 unique titles, 53 peer-reviewed articles met inclusion criteria and were reviewed. These studies mostly examined urban Black youth, finding that adolescents typically carry firearms intermittently throughout adolescence and primarily for self-defense/protection. Seven future research priorities were identified, including: (1) examining adolescent carriage across age, gender, and racial/ethnic subgroups; (2) improving on methodological limitations of prior research, including disaggregating firearm from other weapon carriage and using more rigorous methodology (e.g., random/systematic sampling; broader population samples); (3) conducting longitudinal analyses that establish temporal causality for patterns, motives, and risk/protective factors; (4) capitalizing on m-health to develop more nuanced characterizations of underlying motives; (5) increasing the study of precursors for first-time carriage; (6) examining risk and protective factors beyond the individual-level; and, (7) enhancing the theoretical foundation for firearm carriage within future investigations.

Distinguishing between-individual from within-individual predictors of gun carrying among Black and White males across adolescence

Longitudinal studies have found that male adolescents who deal drugs, associate with delinquent peers, and engage in aggressive behavior are at increased risk for carrying a gun (between-individual risks). However, it is unclear whether changes in these risk factors help to explain fluctuations in youth gun carrying across adolescence (within-individual risks). The current study examined this issue using a community sample of 970 adolescent males (58% Black, 42% White) assessed annually from ages 14 to 18. Multilevel models examined the extent to which between-individual differences and within-individual changes in drug dealing, peer delinquency, aggressive behavior, and neighborhood disadvantage were associated with gun carrying across adolescence. Each of these predictors, except for disadvantage, exerted a between-individual and within-individual influence for Black youth. For White youth, drug dealing was significant on both levels, peer delinquency was a significant between-individual predictor, and aggression was a significant within-individual predictor. Neighborhood disadvantage did not significantly predict gun carrying in the model, on either the between- or within-individual level, for Black or White youth. These results stress the importance of examining race-specific predictors of gun carrying among Black and White adolescents and point to drug dealing as a robust predictor of gun carrying, at both the between-individual and within-individual levels for youth of either race. Efforts to prevent drug market involvement and reduce aggressive behaviors in adolescence may in turn prove useful for preventing firearm violence.

Editors' Best of 2018

There is, in the content of the Journal, an embarrassment of riches, and picking a "best" seems to demand a certain qualification: is the "best" the most interesting, most surprising, most educational, most important, most provocative, most enjoyable? How to choose? We are hardly unbiased and can admit to a special affection for the ones that we and the authors worked hardest on, hammering version after version into shape. Acknowledging these biases, here are the 2018 articles that we think deserve your attention or at least a second read.
