Exposure to Community Violence and the Trajectory of Internalizing and Externalizing Symptoms in a Sample of Low-Income Urban Youth

The effects of two types of neighborhood factors on trajectory of internalizing and externalizing symptoms from early childhood to adolescence

Although a robust body of previous empirical studies investigated the long-term trend of child behavior problems, limited research discussed the influences of various types of neighborhood factors on such trajectory (e.g., neighborhood structural characteristics and collective efficacy). Using a nationally representative longitudinal dataset the Fragile Families and Child Wellbeing Study (FFCWS), with six waves from 1998 to 2017, this study captures the longitudinal effects of two types of early childhood neighborhood factors on the co-development of internalizing and externalizing symptoms. Data was collected at the focal child's age 3, age 5, age 9, age 15 (N = 2,385), and the parallel-process growth curve models were applied. Results suggest that the trajectories of both internalization and externalizing symptoms showed U-shape and bidirectional relationships among internalizing and externalizing problems. The long-term effects of neighborhood social cohesion and economic disadvantages were significantly associated with children's internalizing and externalizing symptoms. The implication of this study was further discussed.

Behavioral and neurostructural correlates of childhood physical violence victimization: Interaction with family functioning

Violence victimization may cause child behavior problems and neurostructural differences associated with them. Healthy family environments may buffer these effects, but neural pathways explaining these associations remain inadequately understood. We used data from 3154 children (x̅age  = 10.1) to test whether healthy family functioning moderated possible associations between violence victimization, behavior problems, and amygdala volume (a threat-responsive brain region). Researchers collected data on childhood violence victimization, family functioning (McMaster Family Assessment Device, range 0-3, higher scores indicate healthier functioning), and behavior problems (Achenbach Child Behavior Checklist [CBCL] total problem score, range 0-117), and they scanned children with magnetic resonance imaging. We standardized amygdala volumes and fit confounder-adjusted models with "victimization × family functioning" interaction terms. Family functioning moderated associations between victimization, behavior problems, and amygdala volume. Among lower functioning families (functioning score = 1.0), victimization was associated with a 26.1 (95% confidence interval [CI]: 9.9, 42.4) unit higher CBCL behavior problem score, yet victimized children from higher functioning families (score = 3.0) exhibited no such association. Unexpectedly, victimization was associated with higher standardized amygdala volume among lower functioning families (ŷ = 0.5; 95% CI: 0.1, 1.0) but lower volume among higher functioning families (ŷ = -0.4; 95% CI: -0.7, -0.2). Thus, healthy family environments may mitigate some neurobehavioral effects of childhood victimization.

Co-occurrence of Psychopathology Problems in At-Risk Adolescents

No known studies have investigated co-occurrence of psychopathology problems in adolescents with biologic and/or environmental susceptibility, including prenatal drug exposure. This study identified comorbidity patterns of psychopathology problems by utilizing data from urban, primarily African American, youth, majority of whom were at heightened risk for exposure to drugs in utero. The roles of Research Domain Criteria (RDoC)-informed behavioral constructs of the Negative Valence (irritability) and Social Process Systems (social disinhibition) as antecedents of the comorbidity patterns were further examined. Lastly, the predictive validity of the identified patterns was evaluated in relation to emerging adulthood outcomes. Participants were 358 urban adolescents, primarily African Americans, drawn from a 21-year prospective birth-cohort study of the effects of prenatal drug exposure. Psychopathology problems were assessed at age 15. Irritability and social disinhibition were self-reported at age 12. Emerging adulthood outcomes were measured at age 21. Latent class modeling indicated four patterns: Normative (57%), substance-use (SU; 24%), mental-health-problems-without-substance-use (MH; 11%), and substance-use-and-other-mental-health-problems (SUMH; 7%). Higher irritability increased the odds of developing the MH pattern, whereas higher social disinhibition increased the odds of developing the SU pattern. The odds of manifesting the SUMH pattern were higher for children with higher irritability. For children with higher social disinhibition, the odds of manifesting the SUMH pattern were higher at a trend level. Adolescent comorbidity patterns were differentially associated with problematic tobacco and marijuana use and clinically relevant mental health problems in emerging adulthood, and completion of high school education. Peri-pubertal identification of individual differences in irritability and social disinhibition may mitigate the emergence of adolescent psychopathology, which could influence emerging adulthood adjustment in this at-risk population.

Examining the Pathologic Adaptation Model of Community Violence Exposure in Justice Involved Adolescents: the Moderating and Mediating Effects of Moral Disengagement

According to the pathologic adaptation model (Ng-Mak et al. in The American Journal of Orthopsychiatry, 72, 92-101, 2002), youth who experience community violence exposure may become desensitized to these experiences. Moral disengagement, which refers to changing one's moral or ethical standards to justify engaging in destructive or harmful behavior, has been proposed as a construct to explain the relation between community violence exposure and desensitization (Bandura et al., 1996). The purpose of the current study was to test the pathologic adaptation model of community violence exposure and examine the role of moral disengagement in these pathways. The current study included a sample of justice-involved adolescents (n = 1,170; M age = 16.05, SD = 1.16) from the Pathways to Desistance study. The PROCESS bootstrapping procedure for SPSS was used to examine whether moral disengagement mediates the associations from community violence to aggressive behaviors and depressive. Exploratory analyses examined moral disengagement as a moderator these associations. Moral disengagement significantly moderated the association between witnessing violence and self-reported offending such that witnessing violence at baseline significantly positively predicted offending for individuals who were moderate to high (but not low) in moral disengagement. In contrast, moral disengagement did not moderate the linear association between community violence exposure and depressive symptoms. Further, moral disengagement did not mediate the association between community violence exposure and offending. Results from this study highlight the need to increase access to mental health services and re-entry programs to reduce offending behaviors for justice-involved youth.

Adolescent Mental Health and Family Economic Hardships: The Roles of Adverse Childhood Experiences and Family Conflict

Rising and economically disproportionate rates of adverse mental health outcomes among children and youth warrant research investigating the complex pathways stemming from socioeconomic status. While adverse childhood experiences (ACEs) have been considered a possible mechanism linking socioeconomic status (SES) and child and youth psychopathology in previous studies, less is understood about how family environments might condition these pathways. Using data from a longitudinal, multiple-wave study, the present study addresses this gap by examining the direct relationships between family economic status and youth internalizing and externalizing symptoms, if ACEs mediate these relationships, and if conflictual family environments moderate these direct and indirect relationships. The data were obtained from 5510 youth participants [mean age at baseline = 9.52 (SD = 0.50), 47.7% female, 2.1% Asian, 10.3% Black, 17.6% Hispanic, 9.8% Multiracial/Multiethnic, 60.2% White] and their caretakers from the baseline, 1-year, and 2-year follow up waves. Conditional process analysis assessed the direct, indirect, and moderated relationships in separate, equivalent models based on youth- versus caregiver-raters of ACEs and youth psychopathology to capture potential differences based on the rater. The results of both the youth- and caregiver-rated models indicated that lower family economic status directly predicted higher levels of externalizing symptoms, and ACEs indirectly accounted for higher levels of internalizing and externalizing symptoms. Additionally, family conflict moderated some, but not all, of these relationships. The study's findings highlight that lower family economic status and ACEs, directly and indirectly, contribute to early adolescent psychopathology, and conflictual family environments can further intensify these relationships. Implementing empirically supported policies and interventions that target ACEs and family environments may disrupt deleterious pathways between SES and youth psychopathology.

U.S. Mexican-Origin Adolescents' Well-Being in the Context of Neighborhood White Concentration: Dismantling Systems of Racism and Oppression during Adolescence

To address injustices that privilege whiter neighborhoods, many advocate for residential integration. The developmental consequences of greater exposure to whiteness associated with integration, however, are unclear. Research examining BIPOC adolescent development within the context of intraindividual changes in neighborhood white concentration-the changes that take place if an adolescent moves to a whiter neighborhood or if their neighborhood becomes whiter-is needed. We examined trajectories of internalizing and externalizing symptoms in a longitudinal sample of U.S. Mexican adolescents (N = 749; 48.9% girls; 70.2% born in the United States). When adolescents experienced an uptick in neighborhood white concentration, they experienced a corresponding uptick in externalizing symptoms. We discuss the impacts of navigating whiter neighborhoods for U.S. Mexican adolescent well-being.

Making meaning of community violence among adolescents: Associations between exposure, pro-violence attitudes and psychological symptoms

This study examined one type of adolescent meaning making (i.e., the development of beliefs about violence) and its association with reported mental health symptoms in a sample of youth exposed to community violence. Eighty-seven adolescents (age 11-18; 64.4% female) from a metropolitan city in the Northeast were recruited through Craigslist and recreation center postings and data collection occurred from 2009 to 2013. Participants completed self-reported measures of community violence exposure, attitudes toward violence, and psychological symptoms of depression and posttraumatic stress disorder [PTSD]. Bivariate correlations, hierarchical linear regressions, and mediation analyses examined the associations between exposure, beliefs about violence, and mental health symptoms. Self-reported pro-violence attitudes were positively correlated with depression symptoms (r = 0.32, p < 0.01) and PTSD (r = 0.45, p < 0.01). Pro-violence attitudes significantly mediated the relationship between community violence exposure and depression symptoms (95% confidence interval [CI] = 0.003-0.061) and PTSD symptoms (95% CI = 0.046-0.260). Preliminary findings suggest that meaning making through the development of pro-violence attitudes may not protect against symptoms of PTSD and depression among youth. Findings can inform the integration of meaning making processes into community mental health interventions for youth.

Witnessing Intimate Partner Violence Across Contexts: Mental Health, Delinquency, and Dating Violence Outcomes Among Mexican Heritage Youth

Immigrant Mexican American (MA) youth are at greater risk for violence exposure due to risk factors associated with migration-postmigration processes and as they settle into urban U.S. communities marked by crime and poverty. Less is known about the contexts of this exposure. Specifically, what are the ecological contexts in which youth witness intimate partner violence (IPV), how do these experiences differ by immigration generational status, and what is the impact on youth's externalizing and internalizing behaviors? MA adolescents (N = 279; 15-17 years, M = 16.17, SD = 0.81) from the Southwest United States participated in an online survey. Over half of adolescents had witnessed at least one incidence of IPV in the prior 2 weeks, usually involving their peers. Adolescents who had spent more time in the United States were more likely to witness violence and rated it as more severe than more recently immigrated youth. A cross-sectional path model revealed that witnessing IPV was associated with internalizing and externalizing problems. However, the associations between witnessing IPV and dating violence perpetration and victimization were mediated through acceptance of dating violence norms. Each successive generation may be more likely to witness violence across a range of ecological contexts. Witnessing violence may be central to a host of negative outcomes, including deviancy, poor mental health, and dating violence. However, preventive interventions can help youth to challenge violence norms within intimate partnerships as well as to cope with violence in their homes, peer groups, and communities.

Exploring exposure to intertwined community violence among Uruguayan adolescents using a mixed-method approach

Building on the case of adolescents (aged 12-16 years) from underprivileged neighborhoods in Montevideo, two studies explore patterns of exposure to community violence among understudied South American youth. Applying a mixed-methods approach, the first study (n = 117) used principal component analysis to examine response patterns on a self-reported exposure to community violence scale. The second study examined subjective experience, drawing from focus group discussions with adolescents (n = 27) and their teachers (n = 22). Events were clustered into three components: indirect violence, traumatic violence, physical/verbal abuse, and robbery. Participants described the severity of violence in relation to chronic exposure, processes of naturalization, and permeable boundaries among the neighborhood, school, family, and social media networks. Violence chronicity and potential threats to life appear to be central dimensions in community violence reporting. Delimitating the study of community violence based on the setting or perceptual closeness has limited socioecological relevance.

Association of Neighborhood Gun Violence With Mental Health-Related Pediatric Emergency Department Utilization

IMPORTANCE

Many children and adolescents in the United States are exposed to neighborhood gun violence. Associations between violence exposure and children's short-term mental health are not well understood.

OBJECTIVE

To examine the association between neighborhood gun violence and subsequent mental health-related pediatric emergency department (ED) utilization.

DESIGN, SETTING, AND PARTICIPANTS

This location-based cross-sectional study included 128 683 ED encounters for children aged 0 to 19 years living in 12 zip codes in Philadelphia, Pennsylvania, who presented to an urban academic pediatric ED from January 1, 2014, to December 31, 2018. Children were included if they (1) had 1 or more ED visits in the 60 days before or after a neighborhood shooting and (2) lived within a quarter-mile radius of the location where this shooting occurred. Analysis began August 2020 and ended May 2021.

EXPOSURE

Neighborhood violence exposure, as measured by whether a patient resided near 1 or more episodes of police-reported gun violence.

MAIN OUTCOMES AND MEASURES

ED encounters for a mental health-related chief complaint or primary diagnosis.

RESULTS

A total of 2629 people were shot in the study area between 2014 and 2018, and 54 341 children living nearby had 1 or more ED visits within 60 days of a shooting. The majority of these children were Black (45 946 [84.5%]) and were insured by Medicaid (42 480 [78.1%]). After adjusting for age, sex, race and ethnicity, median household income by zip code, and insurance, children residing within one-eighth of a mile (2-3 blocks) of a shooting had greater odds of mental health-related ED presentations in the subsequent 14 days (adjusted odds ratio, 1.86 [95% CI, 1.20-2.88]), 30 days (adjusted odds ratio, 1.49 [95% CI, 1.11-2.03]), and 60 days (adjusted odds ratio, 1.35 [95% CI, 1.06-1.72]).

CONCLUSIONS AND RELEVANCE

Exposure to neighborhood gun violence is associated with an increase in children's acute mental health symptoms. City health departments and pediatric health care systems should work together to provide community-based support for children and families exposed to violence and trauma-informed care for the subset of these children who subsequently present to the ED. Policies aimed at reducing children's exposure to neighborhood gun violence and mitigating the mental symptoms associated with gun violence exposure must be a public health priority.

Comparison of three models of adverse childhood experiences: Associations with child and adolescent internalizing and externalizing symptoms

Exposure to adverse childhood experiences (ACEs) is prevalent and confers risk for psychopathology later in life. Approaches to understanding the impact of ACEs on development include the independent risk approach, the Dimensional Model of Adversity and Psychopathology (DMAP) distinguishing between threat and deprivation events, and the cumulative risk approach. The present research provides an empirical confirmation of DMAP and a comparison of these three approaches in predicting internalizing and externalizing symptoms in youth. In Study 1, mental health professionals (N = 57) rated ACEs as threat or deprivation events. These ratings were used to create composites to represent the DMAP approach in Study 2. With cross-sectional and longitudinal data from children and adolescents in state custody (N = 23,850), hierarchical linear regression analyses examined independent risk, DMAP, and cumulative risk models in predicting internalizing symptoms, disinhibited externalizing symptoms, and antagonistic externalizing symptoms. All three approaches produced significant models and revealed associations between exposure to ACEs and symptoms. Individual risk accounted for significantly more variance in symptoms than cumulative risk and DMAP. Cumulative risk masked differential associations between ACEs and psychological symptoms found in the individual risk and DMAP approaches.

Bidirectional Relations between Witnessing Violence, Victimization, Life Events, and Physical Aggression among Adolescents in Urban Schools

Although there is empirical evidence supporting associations between exposure to violence and engaging in physically aggressive behavior during adolescence, there is limited longitudinal research to determine the extent to which exposure to violence is a cause or a consequence of physical aggression, and most studies have not addressed the influence of other negative life events experienced by adolescents. This study examined bidirectional relations between physical aggression, two forms of exposure to violence-witnessing violence and victimization, and other negative life events. Participants were a sample of 2568 adolescents attending three urban public middle schools who completed measures of each construct every 3 months during middle school. Their mean age was 12.76 (SD = 0.98); 52% were female. The majority were African American (89%); 17% were Hispanic or Latino/a. Cross-lagged regression analyses across four waves of data collected within the same grade revealed bidirectional relations between witnessing violence and physical aggression, and between witnessing violence and negative life events. Although physical aggression predicted subsequent changes in victimization, victimization predicted changes in physical aggression only when witnessing violence was not taken into account. Findings were consistent across sex and grades. Overall, these findings highlight the need for interventions that break the connection between exposure to violence and aggression during adolescence.

Co-occurrence of Violence-Related Risk and Protective Behaviors and Adult Support Among Male Youth in Urban Neighborhoods

IMPORTANCE

Male youth in lower-resource neighborhoods bear a disproportionate burden of violence involvement, but little is known about clusters of specific violence-related behaviors to inform cross-cutting interventions that address multiple forms of violence.

OBJECTIVE

To examine associations between adult support and patterns of violence and risk or protective behavior co-occurrence among male youths in urban neighborhoods.

DESIGN, SETTING, AND PARTICIPANTS

Cross-sectional analysis of baseline and end-of-program data from a recently completed cluster-randomized sexual violence prevention trial across 20 lower-resource neighborhoods. Participants were male youths, aged 13 to 19 years, enrolled at youth-serving community agencies in Pittsburgh, Pennsylvania, from July 27, 2015, to June 5, 2017. Data were analyzed from July 1, 2018, to February 28, 2019.

EXPOSURES

Social support and natural mentoring, as defined by validated survey measures.

MAIN OUTCOMES AND MEASURES

Validated survey measures (youth violence, bullying, sexual and dating violence, history of exposure to violence and related adversities, substance use, school engagement, and future orientation) were assessed for detailed co-occurrence patterns using hierarchical clustering, dendrograms, and heatmaps across prespecified domains. Wilcoxon rank sum tests and logistic regression models examined associations between adult support and violence involvement.

RESULTS

Among 866 participants, the mean (SD) age was 15.5 (1.6) years and 632 participants (77.5%) identified as African American. All 866 participants completed baseline surveys and 577 completed end-of-program surveys. Seven clusters of risk and protective behaviors emerged: (1) school engagement; (2) career and future aspirations; (3) substance use and bullying exposure; (4) exposure to violence and related adversities, sexual violence exposure, peer delinquency, and gang involvement; (5) sexual violence, youth violence, and bullying perpetration; (6) dating abuse perpetration; and (7) physical or sexual partner violence perpetration. The strongest association cluster occurred among sexual violence perpetration behaviors. Youth with high social support engaged in significantly fewer of the 40 prespecified risk behaviors (high social support median [interquartile range], 8 [5-12] behaviors vs low social support median [interquartile range], 10 [6-14] behaviors; mean difference, 1.64 behaviors; 95% CI, 0.63-2.64 behaviors; P = .004). High social support and natural mentoring were both inversely associated with gang involvement (social support: odds ratio [OR], 0.39; 95% CI, 0.22-0.71; and natural mentoring: OR, 0.44; 95% CI, 0.25-0.76) and sexual violence exposure (social support: OR, 0.39; 95% CI, 0.24-0.64; and natural mentoring: OR, 0.61; 95% CI, 0.39-0.98).

CONCLUSIONS AND RELEVANCE

These findings suggest that co-occurrence of risk and protective behaviors differ significantly among youth with vs without adult support. Violence prevention interventions designed to leverage adult support should address broader co-occurrence patterns.

Positive School Climate as a Moderator of Violence Exposure for Colombian Adolescents

In Colombia, many adolescents have experienced violence related to the decades-long armed conflict in the country and have witnessed or been directly victimized by violence in their communities, often related to gang activity or drug trafficking. Exposure to violence, both political and community violence, has detrimental implications for adolescent development. This study used data from 1857 Colombian adolescents in an urban setting. We aim to understand the relations between exposure to violence and adolescent outcomes, both externalizing behaviors and developmental competence, and then to understand whether school climate (i.e., safety, connectedness, services) moderates these relations. Results demonstrate that armed conflict, community violence victimization, and witnessing community violence are positively associated with externalizing behaviors, but only armed conflict is negatively associated with developmental competence. School safety, connectedness, and services moderate the relation between community violence witnessing and externalizing behaviors. School services moderates the relation between community violence victimization and developmental competence. As students perceived more positive school climate, the effects of community violence exposure on outcomes were weakened. This study identifies potential levers for intervention regarding how schools can better support violence-affected youth through enhancements to school safety, connectedness, and services.
