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.

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.

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.

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.

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.

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.

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.

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.

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.

Children's exposure to violent political conflict stimulates aggression at peers by increasing emotional distress, aggressive script rehearsal, and normative beliefs favoring aggression.

We examine the hypothesis that children's exposure to ethnic-political conflict and violence over the course of a year stimulates their increased aggression toward their own in-group peers in subsequent years. In addition, we examine what social cognitive and emotional processes mediate these effects and how these effects are moderated by gender, age, and ethnic group. To accomplish these aims, we collected three waves of data from 901 Israeli and 600 Palestinian youths (three age cohorts: 8, 11, and 14 years old) and their parents at 1-year intervals. Exposure to ethnic-political violence was correlated with aggression at in-group peers among all age cohorts. Using a cross-lagged structural equation model from Year 1 to Year 3, we found that the relation between exposure and aggression is more plausibly due to exposure to ethnic-political violence stimulating later aggression at peers than vice versa, and this effect was not moderated significantly by gender, age cohort, or ethnic group. Using three-wave structural equation models, we then showed that this effect was significantly mediated by changes in normative beliefs about aggression, aggressive script rehearsal, and emotional distress produced by the exposure. Again the best fitting model did not allow for moderation by gender, age cohort, or ethnic group. The findings are consistent with recent theorizing that exposure to violence leads to changes both in emotional processes promoting aggression and in the acquisition through observational learning of social cognitions promoting aggression.

Assessing Callous-Unemotional Traits in Adolescents: Determining Cutoff Scores for the Inventory of Callous and Unemotional Traits.

OBJECTIVE: This study aims to establish a cut score for the Inventory of Callous-Unemotional Traits, a well-validated measure of callous-unemotional (CU) traits in youth for which there is currently no cutoff score. METHOD: We analyzed data on 634 adolescents from high schools (n = 343) and juvenile detention centers (n = 291). Participants, their parents and guardians, and their teachers and staff members reported on participants' CU traits and aggressive/violent behavior. RESULTS: All three reports of CU traits as well as intersource composites were associated with aggression, violence, and detained status. Parent report was a better indicator compared to self-reports and teacher reports. Appropriate cut scores based on each report and composite were determined. CONCLUSION: We recommend that information from all available informants should be used whenever possible, but when only one informant report is feasible, parent reports are preferable.

Growing Up Amid Ethno-Political Conflict: Aggression and Emotional Desensitization Promote Hostility to Ethnic Outgroups.

Ethno-political violence impacts thousands of youth and is associated with numerous negative outcomes. Yet little research examines adaptation to ethno-political violence over time or across multiple outcomes simultaneously. This study examines longitudinal patterns of aggressive behavior and emotional distress as they co-occur among Palestinian (n = 600) youth exposed to ethno-political violence over 3 years in three age cohorts (starting ages: 8, 11, and 14). Findings indicate distinct profiles of aggressive behavior and emotional distress, and unique joint patterns. Furthermore, youth among key joint profiles (e.g., high aggression-emotional desensitization) are more likely to endorse normative beliefs about aggression toward ethnic outgroups. This study offers a dynamic perspective on emotional and behavioral adaptation to ethno-political violence and the implications of those processes.

Exploring Primary and Secondary Variants of Psychopathy in Adolescents in Detention and in the Community.

The current study aims to ascertain how different variants of callous-unemotional traits differ in their psychopathology, exposure to aggression and violence, and aggressive and violent behavior. If secondary/distressed variants (high in callous-unemotional traits and high in anxiety) and primary/traditional variants (high in callous-unemotional traits and low in anxiety) differ along these dimensions, it may speak to their different etiologies, treatment needs (e.g., trauma focused), and responsiveness to treatment. The current sample consisted of 799 adolescents from high schools (n = 419) and juvenile detention centers (n = 380). Participants were interviewed regarding their callous-unemotional traits, psychopathology, exposure to aggression and violence, and aggressive and violent behavior. Parents/guardians and teachers/staff members also reported on participants' callous-unemotional traits and aggressive and violent behavior. A model-based cluster analysis indicated that there were four clusters in the data set, based on callous-unemotional traits and anxiety: a nonvariant cluster, a primary/traditional callous-unemotional cluster, a secondary/distressed callous-unemotional cluster, and a "fearful" cluster. Secondary/distressed variants of psychopathy exhibited significantly greater symptoms of depression and psychoticism, more exposure to low level aggression and neighborhood violence, and more aggressive and violent behavior, as compared to the other clusters. Adolescents with callous-unemotional traits might not be a homogeneous group, but rather may differ in attitudes, behaviors, and exposure to risk, therefore differing in their treatment needs and responsiveness.

Violence and Victimization During Incarceration: Relations to Psychosocial Adjustment During Reentry to the Community.

We surveyed male ex-offenders (N = 100) about their experiences during and prior to incarceration to assess the role of these factors in psychosocial adjustment postrelease. Participants completed measures of preincarceration mental health problems and severe victimization and feelings of safety during incarceration; they also self-reported emotional distress, antisocial behavior, and posttraumatic stress (PTS). Moderator analyses of PTS outcomes revealed two key interactions between preincarceration mental health problems and severe victimization during incarceration as well as preincarceration mental health problems by feelings of safety during incarceration. In those without preincarceration mental health problems, victimization and PTS were significantly positively related; this was not the case for those with preexisting mental problems. Furthermore, the positive relation between feeling unsafe and PTS was stronger among those with preexisting mental problems. Findings are discussed with respect to implications for reentry services.

Childhood and Adolescent Risk and Protective Factors for Violence in Adulthood.

PURPOSE: We use data from a community sample followed from ages 8 to 48. We focus on the main and risk-buffering effects of childhood and adolescent protective factors for predicting adulthood violence (official records and self reports). METHOD: Males (N=436) from the Columbia County Longitudinal Study participated. 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: Risk factors for adulthood violence included higher aggression and lower family socioeconomic status at ages 8 and 19. Protective factors included anxiety about behaving aggressively (ages 8 and 19), popularity (ages 8 and 19), family church attendance (age 8), lower negative family interactions (age 8), and higher educational aspirations (age 19). For youth with at least one risk factor, the sum of adolescent-but not childhood--protective factors reduced the likelihood of adulthood violence. The most critical adolescent risk-buffering protective factors were anxiety about behaving aggressively and educational aspirations. CONCLUSIONS: Aggression and low family SES, even by age 8, place youth at risk for adulthood violence. Interventions to strengthen critical protective factors must continue into late adolescence to reduce the likelihood of adulthood violence among at-risk youth.

Country, sex, and parent occupational status: moderators of the continuity of aggression from childhood to adulthood.

Using data from two American and one Finnish long-term longitudinal studies, we examined continuity of general aggression from age 8 to physical aggression in early adulthood (age 21-30) and whether continuity of aggression differed by country, sex, and parent occupational status. In all samples, childhood aggression was assessed via peer nominations and early adulthood aggression via self-reports. Multi-group structural equation models revealed significant continuity in aggression in the American samples but not in the Finnish sample. These relations did not differ by sex but did differ by parent occupational status: whereas there was no significant continuity among American children from professional family-of-origin backgrounds, there was significant continuity among American children from non-professional backgrounds.

Using police data to measure children's exposure to neighborhood violence: a new method for evaluating relations between exposure and mental health.

Studies have identified a robust association between children's exposure to violence and their mental health. Yet, most of this research has been based on self-reported exposure and self-reported mental health. In this study, we used a new, map-based method via police data for measuring children's exposure to violent crime and compared it to child self-reports and parent reports of exposure. Results suggest that child self-reports of violence exposure may not be valid except for exposure to murder, but police and parent reports of violent crime can reveal interesting relations between violence and mental health. Children showed higher levels of internalizing problems in the absence of police-reported murder and parent-reported robbery. Discussion emphasizes implications for measurement as well as theory building.
