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.

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.

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.

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.

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.

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.

Cardiovascular effects of brief mindfulness meditation among perfectionists experiencing failure.

Research links perfectionism, the tendency to hold and pursue unrealistically high standards, to negative mental health outcomes such as eating disorders, anxiety, and depression. Previous research used high frequency heart rate variability (HF-HRV) to measure recovery from stress during a mindfulness meditation in perfectionistic university students and found that only nonperfectionists demonstrated HF-HRV recovery from stress, suggesting that mindfulness was not effective for perfectionists. However, the mindfulness meditation did not incorporate a nonjudgment element, which may be a key component for perfectionists.

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.

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.

Risk factors for youth violence: Youth violence commission, International Society For Research On Aggression (ISRA).

In March 2018, the President of the International Society for Research on Aggression (ISRA), Mike Potegal, appointed a special commission to prepare a report on youth violence. This commission was “charged with the task of producing a public statement on the known risk factors for youth violence, based on the current state of scientific knowledge. If the Commission finds sufficient evidence of harmful effects, then its public statement may include public policy recommendations.

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.

Conducting longitudinal, process-oriented research with conflict-affected youth: Solving the inevitable challenges.

The reader might get the impression that the four projects described in this Special Section proceeded in a systematic and predictable way. Of course, those of us engaged in each research project encountered pitfalls and challenges along the way. A main goal of this Special Section is to provide pathways and encouragement for those who may be interested in advancing high-quality research on this topic.

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).

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.

Negative Stereotypes of Ethnic Out-groups: A Longitudinal Examination Among Palestinian, Israeli Jewish, and Israeli Arab Youth.

Ethno-political conflict impacts thousands of youth globally and has been associated with a number of negative psychological outcomes. Extant literature has mostly addressed the adverse emotional and behavioral outcomes of exposure while failing to examine change over time in social-cognitive factors in contexts of ethno-political conflict. Using cohort-sequential longitudinal data, the present study examines ethnic variation in the development of negative stereotypes about ethnic out-groups among Palestinian (=600), Israeli Jewish (=451), and Israeli Arab (=450) youth over three years.

The Longitudinal Effects of Chronic Mediated Exposure to Political Violence on Ideological Beliefs About Political Conflicts Among Youths.

This study examines the effects of chronic (i.e., repeated and cumulative) mediated exposure to political violence on ideological beliefs regarding political conflict.

The Effects of Mediated Exposure to Ethnic-Political Violence on Middle East Youth's Subsequent Post-Traumatic Stress Symptoms and Aggressive Behavior.

This study introduces the concept of chronic (i.e., repeated and cumulative) mediated exposure to political violence and investigates its effects on aggressive behavior and post-traumatic stress (PTS) symptoms in young viewers.

Childhood predictors and age 48 outcomes of self-reports and official records of offending.

Background: The key question is: are self-reports and official records equally valid indicators of criminal offending?

Aims: We examine the correspondence between self-reports and official records of offending, the similarity of childhood and adolescent individual and contextual predictors of both measures of offending, and the similarity of age 48 correlates of both measures of offending.

Methods: Men (N=436) from the Columbia County Longitudinal Study, a sample of all 3rd graders in Columbia County, New York, in 1959-60, participated. The youth, their peers and their parents were interviewed when the youth were age 8; the youth were later interviewed at ages 19, 30 and 48.

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.

Foreign Wars and Domestic Prejudice: How Media Exposure to the Israeli-Palestinian Conflict Predicts Ethnic Stereotyping by Jewish and Arab American Adolescents.

This study was based on the theory that adolescents view scenes of violent ethnic conflicts in the mass media through the lens of their own ethnicity, and that the resulting social-cognitive reactions influence their negative stereotypes about similar ethnic groups in their own country. We interviewed 89 Jewish and 180 Arab American high school students about their exposure to the Israeli-Palestinian conflict, their social cognitive reactions to it, and their stereotypes toward ethnic groups. Beyond the effects of ethnic identity, the degree to which adolescents identified with Israelis and Palestinians in the media was a key variable linking exposure to media depictions of the conflict and the implicit ethnic stereotypes they displayed about Jewish Americans and Arab Americans.

Exposure to violence across the social ecosystem and the development of aggression: a test of ecological theory in the Israeli-Palestinian conflict.

Bronfenbrenner's (1979) ecological model proposes that events in higher order social ecosystems should influence human development through their impact on events in lower order social ecosystems. This proposition was tested with respect to ecological violence and the development of children's aggression via analyses of 3 waves of data (1 wave yearly for 3 years) from 3 age cohorts (starting ages: 8, 11, and 14) representing three populations in the Middle East: Palestinians (N = 600), Israeli Jews (N = 451), and Israeli Arabs (N = 450). Results supported a hypothesized model in which ethnopolitical violence increases community, family, and school violence and children's aggression.
