Racial Bias in School Discipline and Police Contact: Evidence From the Adolescent Brain Cognitive Development Social Development (ABCD-SD) Study.

OBJECTIVE: Black youth are disproportionately exposed to school exclusionary discipline. We examined the impact of race on age at the onset of school disciplinary actions and police contact, and the rate of receiving increasingly severe disciplinary actions. METHOD: Youth (N = 2,156) and their caregivers participating in the Adolescent Brain Cognitive Development Social Development (ABCD-SD) study reported on the occurrence and timing of disciplinary events and youths' demographics, delinquency, and neighborhood conditions. Experiences of exclusionary discipline were analyzed using logistic regression and Cox proportional hazards models. RESULTS: Black youth reported significantly higher rates of almost all disciplinary events compared to White youth. In logistic regression and Cox models, Black youth experienced higher risk for exclusionary discipline and police contact (odds ratios from 2.47 [detention] to 5.16 [sent home]; hazard ratios from 1.36 [detention] to 4.71 [expelled]), even after adjusting for sex, delinquency, neighborhood conditions, and the interaction between race and sex. Black youth who received detention and suspension were at higher risk for additional, more severe school discipline than were White youth. CONCLUSION: Consistent with a racial bias in exclusionary discipline practices and policing, Black youth, particularly Black male youth, were at a higher risk for experiencing almost all disciplinary outcomes and at younger ages than White youth, after controlling for delinquency, sex, and neighborhood factors. Compared to White students, school detention and suspension status predicted an accelerated cascade of school discipline outcomes for Black students, suggesting racial disparities in how the severity of school discipline escalates over time.

Exposure to violence predicts callous-unemotional traits and aggression in adolescence in the context of persistent ethnic-political conflict and violence.

According to social-cognitive ecological theory, violence exposure increases emotional factors-such as callous-unemotional (CU) traits-which then contribute to engagement in aggressive behavior. However, previous research has generally not tested this mediational pathway, particularly in the context of persistent ethnic-political violence exposure. The present study examined associations among violence exposure, CU traits, and aggression in a sample of 1051 youth in the Middle East (Palestine and Israel), using youth- and parent-reported data in a cohort-sequential design with three age cohorts (starting ages 8, 11, and 14 years) assessed over four waves spanning 6 years. Results from structural equation models with latent variables indicated that cumulative violence exposure in childhood and adolescence (measured annually for 3 years, and comprising exposure across multiple settings including political, community, family, and school) predicted later CU traits and aggression in adolescence and early adulthood, even after controlling for earlier levels of aggression and CU traits and demographic characteristics (child age and sex and parental socioeconomic status). Additionally, in mediation analyses, CU significantly mediated the association from earlier cumulative violence exposure to concurrent aggression, while aggression did not significantly mediate the association from earlier exposure to concurrent CU traits. The results of this study suggest that violence exposure leads to both aggressive behavior and a constellation of traits that place youth at greater risk for subsequent aggressive behavior, and that CU traits could partially explain the increased risk of aggression after violence exposure.

Developmental Changes in the Relation between Youth Disclosure and Parenting Behavior: A Cohort-sequential Analysis.

To address a gap in the literature regarding the development of youth disclosure across the transition to adolescence, the current research uses a cohort-sequential approach to study youth disclosure from middle childhood through adolescence. Longitudinal data from three cohorts of parents were utilized (N = 1359; children at T1 were in grades 2 [M = 8.00 years, SD = 0.57 years, 45% female], 4 [M = 10.12 years, SD = 0.60 years, 45% female], and 9 [M = 15.19 years, SD = 0.57 years, 48% female]). Parents were assessed annually over a 3-year time period. The focal analyses explored contemporaneous associations between characteristics of the parent-youth relationship (specifically, parental rejection and parental consistent discipline) and youth disclosure after accounting for person-specific trajectories of disclosure. Associations of gender, age, and socioeconomic status with disclosure were also assessed. Regarding trajectories of youth disclosure, results indicate that youth disclose less information to their parents about their daily lives as they get older; this trend was consistent across gender and socioeconomic status. In terms of associations with youth disclosure, when parents provided more consistent discipline or engaged in less rejection of their child, youth disclosure increased, even after accounting for their own trajectory of disclosure across time. In addition, the association of consistent discipline with youth disclosure became stronger with increased youth age. Results are discussed in terms of implications for understanding youth autonomy development, and the dyadic and developmental impact of parenting behaviors over time.

Consequences of Exposure to War Violence: Discriminating Those with Heightened Risk for Aggression from Those with Heightened Risk for Post-Traumatic Stress Symptoms.

Chronic exposure to ethnic-political and war violence has deleterious effects throughout childhood. Some youths exposed to war violence are more likely to act aggressively afterwards, and some are more likely to experience post-traumatic stress symptoms (PTS symptoms). However, the concordance of these two outcomes is not strong, and it is unclear what discriminates between those who are at more risk for one or the other. Drawing on prior research on desensitization and arousal and on recent social-cognitive theorizing about how high anxious arousal to violence can inhibit aggression, we hypothesized that those who characteristically experience higher anxious arousal when exposed to violence should display a lower increase in aggression after exposure to war violence but the same or a higher increase in PTS symptoms compared to those low in anxious arousal. To test this hypothesis, we analyzed data from our 4-wave longitudinal interview study of 1051 Israeli and Palestinian youths (ages at Wave 1 ranged from 8 to 14, and at Wave 4 from 15-22). We used the 4 waves of data on aggression, PTS symptoms, and exposure to war violence, along with additional data collected during Wave 4 on the anxious arousal participants experienced while watching a very violent film unrelated to war violence (N = 337). Longitudinal analyses revealed that exposure to war violence significantly increased both the risk of subsequent aggression and PTS symptoms. However, anxious arousal in response to seeing the unrelated violent film (measured from skin conductance and self-reports of anxiety) moderated the relation between exposure to war violence and subsequent psychological and behavioral outcomes. Those who experienced greater anxious arousal while watching the violent film showed a weaker positive relation between amount of exposure to war violence and aggression toward their peers but a stronger positive relation between amount of exposure to war violence and PTS symptoms.

Within-Person Bidirectional Associations Over Time Between Parenting and Youths' Callousness.

OBJECTIVE: Callousness has been identified as a key driver of aggressive and violent behavior from childhood into early adulthood. Although previous research has underscored the importance of the parenting environment in contributing to the development of youth callousness, findings have generally been confined to the between-individual level and have not examined bidirectionality. In the current study, we test whether aspects of parenting are associated with callousness from childhood to adolescence both between and within individuals, examine the temporal ordering of associations, and test whether these relations are moderated by gender or developmental stage. METHOD: Data came from a longitudinal study in which parents of 1,421 youth (52% girls; 62% White and 22% Black) from the second, fourth, and ninth grades were interviewed three times, with one year between consecutive interviews. RESULTS: A random-intercept cross-lagged panel model indicated that elevated youth callousness predicts subsequent increases in parental rejection and decreases in consistency of discipline. Findings were largely similar for boys and girls, but within-individual associations were generally stronger for 4th graders compared to the 2nd and 9th graders. CONCLUSIONS: Callousness and parenting practices and attitudes were related both at the between-individual and within-individual level. These results have implications for the etiology and treatment of children and adolescents who exhibit callousness.

Trauma and Gang Affiliation Increase Likelihood of Committing Assault among Juveniles Admitted to Secure Custody.

OBJECTIVES: To examine the prediction of involvement in serious physical assault from risk factors collected during routine screening of juveniles admitted to secure custody with a focus on trauma and gang affiliation and an exploration of gender differences in risk. METHODS: We analyzed administrative data collected on 879 juvenile offenders (93% boys; M age = 17 years; 71% Black, 19% Hispanic, 9% White, 1% other race/ethnicity), including extensive data on histories of trauma exposure and other risk as well as gang affiliation. RESULTS: We found that participation in serious assault was linked to gender, gang affiliation, and both witnessing and experiencing various traumatic events. Contrary to predictions, we did not observe a significant interaction between trauma histories and gang affiliation in predicting serious physical assault. CONCLUSIONS: Trauma and gang affiliation are critical yet understudied aspects of violence perpetration in the justice-involved youth population, particularly among clinical child and adolescent psychologists. These results underscore the importance of continued efforts by clinical psychologists to enhance research and practice related to these issues for this population.

Experiences with police in the community: Racial/ethnic differences in negative encounters and coping reactions.

AIMS: This investigation explores police encounters and police-related coping responses, and the extent to which these relations are impacted by race/ethnicity and beliefs about state authority. METHODS: In two large, diverse samples of undergraduates reporting on their recent experiences in the community, race, experiences with police, and views of police were analyzed as predictors for coping with police presence; attitudes about authority were added in the latter study to explore how views of authority affect interpretation of police encounters and later coping. RESULTS: Negative experiences with police differed by race and consistently predicted coping with police presence. There was a marginal interaction between views of authority and negative experiences with police, with greater stress response at lower levels of authoritarian attitudes. CONCLUSIONS: This report clarifies interactions with police from the civilian perspective. It suggests individual attitudes meaningfully affect interpretation of police encounters and, in line with recent research recommendations, highlights the need to better understand police encounters as stressors, particularly in relation to race and ethnicity.

Trauma Exposure and Mental Health Needs Among Adolescents Involved With the Juvenile Justice System.

Justice-involved adolescents typically report high levels of lifetime trauma exposure, although research on juvenile justice system-wide screenings is limited. Further, there is little evidence from research on the psychological and substance abuse treatment related needs of youth relative to the trauma levels or types of trauma experienced by justice-involved adolescents. We documented lifetime exposure to traumatic events and its relation to psychological and substance use concerns in a sample of adolescents admitted to custody in the New Jersey Juvenile Justice Commission. This study examined lifetime exposure to traumatic events experienced by justice-involved adolescents (N = 627) using negative binomial regression modeling and zero-inflated negative binomial regression modeling to identify which adolescents have the greatest trauma exposure, and determine how cumulative types of trauma relate to youths' mental health and substance use needs. Adolescents reported experiencing an average of 4 of 17 traumatic exposures on the Life Events Checklist. The most common traumas experienced directly and indirectly were physical assault and assault with a weapon. Considering particular traumas, there were differences in exposures based on race and ethnicity, sex, child welfare involvement, and gang affiliation. Higher levels of some types of traumatic exposure were consistently related to higher levels of mental health needs. Results indicate that adolescents enter the juvenile justice system with high levels of polytraumatization. These adverse events are associated with elevated mental health and substance use needs that should be considered in case planning.

The Impact of Firearm Legislation on Firearm Deaths, 1991-2017.

Firearm violence is a major public health concern in the USA with firearm suicide and homicide accounting for the majority of gun deaths. The present work seeks to explore the role of firearm legislation in reducing suicide and homicide rates. Using the State Firearm Law Database (www.statefirearmlaws.org), suicide and homicide rates were compared across the 50 US states from 1991 to 2017. A firearm regulations index was computed to represent the total number of state firearm laws. Generalized estimating equations were used to explore population-level increases or decreases in firearm regulations and their association with state suicide and homicide rates after controlling for several state-level covariates. Even after accounting for several key covariates (US region; time; gun ownership; percent of the state population that was White, Black, below the poverty line and 25 years or older with a bachelor's degree; incarceration rate, unemployment rate and divorce rate), we found that firearm laws significantly predicted state firearm suicide and homicide rates. States with greater numbers of laws had reduced suicide and homicide rates compared with those with fewer laws. The present findings point to the role of firearm legislation in curbing rates of gun violence across the USA.

Youth Gun and Weapon Carrying and Suicide Rates for Those Aged 24 Years and Younger, 2005-2017.

PURPOSE: Gun access among youth may contribute to youth suicide deaths by increasing practical capability. The present work examines the association between youth gun and weapon carrying behavior and suicide rates among those aged 24 years and younger. METHODS: Using the 2005-2017 Youth Risk Behavior Surveillance System, the associations over time between youth gun and weapon carrying and youth suicide rates were examined. A series of generalized estimating equations were used to examine population-level associations between states and across time. RESULTS: As anticipated youth gun carrying behavior was a significant contributor to the prediction of firearm suicide rates for those aged 24 years and younger, with higher rates of youth gun carrying associated with higher suicide rates. Youth gun carrying was not a significant predictor of overall suicide rates for those aged 24 years and younger. Youth weapon carrying (which includes guns, knives, and other weapons) was a significant predictor of both firearm-specific and overall suicide rates for those aged 24 years and younger. CONCLUSIONS: Previous research has linked youth gun carrying behavior to past year suicide attempts. This study represents the first attempt at examining the associations between youth gun carrying behavior and suicide mortality among the young. In line with our expectations, states with higher percentages of youth reporting gun and weapon carrying behavior had greater rates of suicide among the young (those aged 24 years and younger). The present work points toward the importance of limiting youth access to firearms in reducing suicide mortality.

Longitudinal predictions of young adults' weapons use and criminal behavior from their childhood exposure to violence.

In this study, we examine whether youth who are exposed to more weapons violence are subsequently more likely to behave violently with weapons. We use data collected with a 3-cohort, 4-wave, 10-year longitudinal study of 426 high-risk youth from Flint, Michigan, who were second, fourth, or ninth-graders in 2006-2007. The data were obtained from individual interviews with the youth, their parents, and their teachers, from archival school and criminal justice records, and from geo-coded criminal offense data. These data show that early exposure to weapons violence significantly correlates at modest levels with weapon carrying, weapon use or threats-to-use, arrests for weapons use, and criminally violent acts 10 years later. Multiple regression analyses, controlling for children's initial aggressiveness, intellectual achievement, and parents' income, education, and aggression, reveal statistically significant independent 10-year effects: (1) more early exposure to weapon use within the family predicts more using or threatening to use a gun; (2) more cumulative early violent video game playing predicts more gun using or threatening to use weapons, and normative beliefs that gun use is acceptable; (3) more cumulative early exposure to neighborhood gun violence predicts more arrests for a weapons crime; and (4) more cumulative early exposure to movie violence predicts more weapon carrying. We argue that youth who observe violence with weapons, whether in the family, among peers, or through the media or video games, are likely to be infected from exposure with a social-cognitive-emotional disease that increases their own risk of behaving violently with weapons later in life.

Addressing the inappropriate use of force by police in the United States and beyond: A behavioral and social science perspective.

Recent high-profile incidents involving the deadly application of force in the United States sparked worldwide protests and renewed scrutiny of police practices as well as scrutiny of relations between police officers and minoritized communities. In this report, we consider the inappropriate use of force by police from the perspective of behavioral and social science inquiry related to aggression, violence, and intergroup relations. We examine the inappropriate use of force by police in the context of research on modern policing as well as critical race theory and offer five recommendations suggested by contemporary theory and research. Our recommendations are aimed at policymakers, law enforcement administrators, and scholars and are as follows: (1) Implement public policies that can reduce inappropriate use of force directly and through the reduction of broader burdens on the routine activities of police officers. (2) For officers frequently engaged in use-of-force incidents, ensure that best practice, evidence-based treatments are available and required. (3) Improve and increase the quality and delivery of noncoercive conflict resolution training for all officers, along with police administrative policies and supervision that support alternatives to the use of force, both while scaling back the militarization of police departments. (4) Continue the development and evaluation of multicomponent interventions for police departments, but ensure they incorporate evidence-based, field-tested components. (5) Expand research in the behavioral and social sciences aimed at understanding and managing use-of-force by police and reducing its disproportionate impact on minoritized communities, and expand funding for these lines of inquiry.

Gun Laws and Youth Gun Carrying: Results from the Youth Risk Behavior Surveillance System, 2005-2017.

Youth who carry guns are at increased risk of violence and premature death-but what impact firearm legislation plays in deterring this behavior is less known. The present study aims to fill this gap by exploring the associations between state gun laws and youth gun carrying behavior using the Youth Risk Behavior Surveillance System (YRBSS). This work builds on previous research but expands it by considering a greater number of years than previous work and using an academic, as opposed to an advocacy-based, gun law coding system. Two models were assessed using generalized estimating equations (GEE): (1) youth gun carrying, (2) youth weapon carrying at school (e.g., guns, knives, clubs). The sample for Model 1 included data for 20 of the 50 U.S. states with 1 state from the northeast, 4 from the midwest, 10 from the south, and 5 from the west. The sample for Model 2 included 33 of the 50 U.S. states with 3 states from the northeast, 9 from the midwest, 12 from the south, and 9 from the west. Data for each state across the 2005-2017 YRBSS biennial surveys were included in the analysis. For youth gun carrying and overall weapon carrying, the total gun regulation index was a significant predictor with lower gun regulation index scores associated with greater youth gun and weapon carrying behavior. The present study points to the potential of gun laws in reducing youth gun carrying behavior. States with more gun laws had fewer youth reporting gun-carrying behavior.

Identifying participants for inclusion in hospital-based violence intervention: An analysis of 18 years of urban firearm recidivism.

BACKGROUND: Identifying individuals at highest risk maximizes efficacy of prevention programs in decreasing recidivist gunshot wound (GSW) injury. Characteristics of GSW recidivists may identify this population. Hospital-based violence intervention programs (HVIPs) are one effective strategy; however, programs are expensive, therefore, when possible, epidemiologic data should guide inclusion criteria. METHODS: Seventeen years of all GSW patients presenting to an urban Level I trauma center were reviewed. Countywide murders were reviewed from the same timeframe. Recidivists were any patient presenting twice, either to the hospital or once to the hospital and subsequently dying by firearm. Demographics and characteristics of future recidivists were compared with nonfuture recidivists. RESULTS: There were 9,699 unique intentional, GSW cases reviewed and 1,426 died, leaving 8,273 at risk of recidivism. Five hundred fourteen (6.2%) became recidivists. Most recidivists were African-American men and were younger at first GSW. Median time between incidents was 2.5 years, with a range of 0 days to 16 years. Nearly half were treated and released from the emergency department at their first episode of GSW. For recidivists who died, 128 died at the second incident, 29 at later incidents. Mortality from a second incident of firearm injury is 10% higher than first injuries, second hospitalizations are US $5,000 more expensive, and loss of life has a societal cost of US $167 billion in this community alone. CONCLUSION: The most appropriate population for inclusion in HVIPs at our hospital are young black men. The HVIP services are needed in the emergency department to address those treated and released at first GSW. Recidivists have higher mortality, and hospitalizations are significantly more expensive at the second injury. The investment in prevention is justified and may lead to a decrease in recidivism. LEVEL OF EVIDENCE: Therapeutic/Care Management level III.

Neighborhood Violent Crime and Academic Performance: A Geospatial Analysis.

Decades of empirical work have confirmed that experiences with violence are associated with a variety of adverse behavioral and mental health as well as academic outcomes for children and adolescents. Yet this research largely has relied on indirect measures of exposure. In this study, we apply geospatial analysis to examine the relation between neighborhood violent crime (via police reports) and academic performance (via school-level standardized test proficiency rates). Findings suggest that greater numbers of crimes proximal to school buildings relate to lower levels of academic performance. These results persisted even when controlling economic disadvantage in the student body. Implications for research and policy are discussed.

The impact of childhood maltreatment on adolescent gang involvement.

BACKGROUND: A number of risk factors for gang involvement have been identified in the literature, such as victimization, poor parental monitoring, aggressive behavior, and affiliation with delinquent peers. However, few studies have examined the influence of maltreatment experiences during childhood on gang involvement later in adolescence. OBJECTIVE: This study examines how differential experiences of maltreatment might impact future gang involvement. PARTICIPANTS AND SETTING: We analyze self-report data and official maltreatment records on 611 youth (52% female; 76% non-white) in the US, from a larger dataset (Longitudinal Studies on Childhood Abuse and Neglect; N = 1354). METHODS: Multinomial logistic regression models were used to examine the influence of experiencing different types of maltreatment on gang involvement. RESULTS: Results show that childhood experiences of maltreatment (p = .005) generally and neglect (p = .013) specifically were significantly associated with an increased risk of involvement in stable gang affiliations later in adolescence. CONCLUSIONS: These findings demonstrate the value of considering gang involvement as an outcome of maltreatment and tailoring best practice interventions to support maltreated youth at risk of gang involvement.

Anxiety, Depression, and Offending in the Columbia County Longitudinal Study: A Prospective Analysis from Late Adolescence to Middle Adulthood.

PURPOSE: We use data from a community sample, the Columbia County Longitudinal Study, which followed participants from childhood through adulthood, to examine the longitudinal relations between mental health (serious anxiety and serious depression) and offending across three waves of data collection (ages 19, 30, and 48). METHOD: Participants were from the Columbia County Longitudinal Study (436 males and 420 females). The youth, their parents, and peers were first interviewed when the youth were age 8; the youth were later interviewed at ages 19, 30, and 48. RESULTS: We found significant longitudinal relations from offending to experiencing subsequent severe anxiety and weaker longitudinal relations from experiencing severe anxiety to subsequent offending. For the relation between offending and severe depression, we found similar but somewhat weaker longitudinal associations. Cross-lagged longitudinal structural modelling analyses controlling for the continuity of offending, anxiety, and depression and for family socio-economic status and education were conducted to test the plausibility of alternative causal effects. CONCLUSIONS: The analyses suggest that it is more plausible to conclude that offending is stimulating serious anxiety and depression than to conclude that anxiety and depression are stimulating offending. These results mirror what has been found previously about general aggressive behaviour.

Serious violent behavior and antisocial outcomes as consequences of exposure to ethnic-political conflict and violence among Israeli and Palestinian youth.

We examine whether cumulative-past and concurrent exposure to ethnic-political violence among Israeli and Palestinian youth predict serious violent behavior and antisocial outcomes toward the in-group and the out-group. We collected four waves of data from 162 Israeli Jewish and 400 Palestinian youths (three age cohorts: 8, 11, and 14 years old) and their parents. The first three waves were consecutive annual assessments, and the fourth was conducted 4 years after the third wave, when the three age cohorts were 14, 17, and 20 years old, respectively. Based on social-cognitive-ecological models of the development of aggression (Dubow et al., 2009, Clinical Child and Family Psychology Review, 12, 113-126; Huesmann, 1998) and models of the development of beliefs about the "other," (Bar-Tal, 2004, European Journal of Social Psychology, 34, 677-701; Tajfel & Turner, 1986), we predicted that serious violent outcomes directed toward both the in-group and the out-group would be related to both concurrent and to persistent-past exposure to ethnic political violence. Bivariate regression models (prior to including covariates) indicated that both early cumulative exposure to ethnic-political violence during childhood and adolescence and concurrent exposure during late adolescence/early adulthood predicted all six serious violent and antisocial outcomes. When we added to the models the covariates of ethnic subgroup, age, sex, parents' education, and youths' prior physical aggression, concurrent exposure to ethnic-political violence was still significantly associated with a greater likelihood of concurrently perpetrating all six serious violent and nonviolent forms of antisocial behavior, and earlier cumulative exposure remained significantly related to three of these: severe physical aggression, participating in violent demonstrations, and our overall index of violent/antisocial behavior.

Early maltreatment is associated with greater risk of conduct problems and lack of guilt in adolescence.

Previous research indicates a link between childhood maltreatment and elevated conduct problems. Yet the literature is less clear on associations between maltreatment and callousness (e.g., lack of empathy or guilt). This is a critical gap given that callousness is a robust predictor of serious aggressive and violent behavior. We examine the association between substantiated maltreatment events in childhood and adolescence (up to age 13) and conduct problems and lack of guilt at age 14. We analyze self- and parent-report data along with official maltreatment records on 557 youth (50% female; 69% non-white) from a larger dataset (Longitudinal Studies on Childhood Abuse and Neglect; N = 1354). Results of multinomial logistic regression models indicate that youth with histories of substantiated maltreatment events are more likely to have elevated conduct problems and decreased guilt at age 14, particularly if they experienced maltreatment before the age of four years old. Youth who exhibit conduct problems and also appear to lack guilt are more likely to have a personal history of substantiated maltreatment. We discuss our results in terms of their implications for theory and practice.
