Childhood aggression and peer relations in the context of family and neighborhood factors

Associations between neighborhood characteristics and dating violence: does spatial scale matter?

Background

Dating violence (DV) is a public health problem that could have serious repercussions for the health and well-being of a large number of adolescents. Several neighborhood characteristics could influence these behaviors, but knowledge on such influences is still limited. This study aims at (1) evaluating the associations between neighborhood characteristics and DV, and (2) assessing how spatial scale influences the estimations of the latter associations.

Methods

The Québec Health Survey of High School Students (2016–2017) was used to describe DV. Neighborhoods were operationalized with polygon-based network buffers of varying sizes (ranging from 250 to 1000 m). Multiple data sources were used to describe neighborhood characteristics: crime rate, alcohol outlet density (on-premises and off-premises), walkability, greenness, green spaces density, and youth organizations density. Gendered-stratified logistic regressions were used for assessing the association between neighborhood characteristics and DV.

Results

For boys, off-premises alcohol outlet density (500 m) is associated with an increase in perpetrating psychological DV. Crime rate (500 m) is positively associated with physical or sexual DV perpetration, and crime rate (250 m) is positively associated with physical or sexual DV victimization. Greenness (1000 m) has a protective effect on psychological DV victimization. For girls, walkability (500 m to 1000 m) is associated with a decrease in perpetrating and experiencing psychological DV, and walkability (250 m) is negatively associated with physical or sexual DV victimization.

Conclusions

Several neighborhood characteristics are likely to influence DV, and their effects depend on the form of DV, gender, and spatial scale. Public policies should develop neighborhood-level interventions by improving neighborhood living conditions.

Continuity and Change in the Genetic and Environmental Etiology of Youth Antisocial Behavior

Trajectories of youth antisocial behavior (ASB) are characterized by both continuity and change. Twin studies have further indicated that genetic factors underlie continuity, while environmental exposures unique to each child in a given family underlie change. However, most behavioral genetic studies have examined continuity and change during relatively brief windows of development (e.g., during childhood but not into adolescence). It is unclear whether these findings would persist when ASB trajectories are examined across multiple stages of early development (i.e., from early childhood into emerging adulthood). Our study sought to fill this gap by examining participants assessed up to five times between the ages of 3 and 22 years using an accelerated longitudinal design in the Michigan State University Twin Registry (MSUTR). We specifically examined the etiologies of stability and change via growth curve modeling and a series of univariate and bivariate twin analyses. While participants exhibited moderate-to-high rank-order stability, mean levels of ASB decreased linearly with age. Genetic and nonshared environmental influences that were present in early childhood also contributed to both stability and change across development, while shared environmental contributions were negligible. In addition, genetic and nonshared environmental influences that were not yet present at the initial assessment contributed to change over time. Although ASB tended to decrease in frequency with age, participants who engaged in high levels of ASB during childhood generally continued to do so throughout development. Moreover, the genetic and nonshared environmental contributions to ASB early in development also shaped the magnitude of the decrease with age.

Peer Victimization and Mental Health Problems: Racial-Ethnic Differences in the Buffering Role of Academic Performance

Despite research highlighting the importance of academic performance in reducing youth's bullying involvement, little attention has focused on its role in moderating the association between peer victimization and youth maladjustment, further, there have been even fewer studies examining potential racial-ethnic differences in the association. This cross-sectional study examined the function of academic performance, as a moderator, in the associations between peer victimization and youth mental health problems (i.e., internalizing, externalizing, and substance use problems) and whether and how this function varied by the youth's racial-ethnic background. Self-report data were collected from 69,244 middle and high school youth (45.96% were middle schoolers; 49.7% were females; 25.72% were Black and African American youth, 9.64% Latinx American youth, 5.95% Asian American youth, and 10.47% Bi- and Multi-racial youth, and 48.22% White American youth). Multi-level models indicated that academic performance was negatively related to internalizing problems and substance use more strongly in victimized youth than in non-victimized youth, suggesting itself as a buffering factor. Moreover, this buffering function of academic performance in victimized youth was more pronounced in some ethnic groups (i.e., Asian American) than in others (i.e., Black and Latinx American), yet, notably, it was a buffer across all ethnic groups. These findings underscore the importance of academic strength in protecting victimized youth of all ethnicities against mental health difficulties, while recognizing that additional foci on improving academic performance and addressing academic-related norms are needed for racial-ethnic minority subgroups.

Behavioral Inhibition in Early Childhood and Adjustment in Late Adolescence in China

This study examined relations between behavioral inhibition in toddlerhood and social, school, and psychological adjustment in late adolescence in China. Data on behavioral inhibition were collected from a sample of 2-year-olds (initial N = 247). Follow-up data were collected at 7 years for peer relationships and 19 years for adjustment across domains. The results showed that early inhibition positively predicted later social competence and school adjustment. Peer relationships in middle childhood served as a protective factor in the development of depression of inhibited children. The results indicate the distinct functional meaning of behavioral inhibition in the Chinese context from a developmental perspective.

Development of a scale battery for rapid assessment of risk and resilience

It is critical to understand the factors that increase risk for development of psychiatric disorders as well as promote resilience against disorders. The current study describes the development of a brief tool for risk/resilience assessment that takes a broad perspective of "risk" and "resilience" to characterize the phenomena, and assesses multiple factors that span intrapersonal, interpersonal, and wide-ranging external contexts. We administered twelve scales (212 items) to a diverse population comprising help-seeking and community participants (N = 298; 46% female) in the greater Philadelphia area. We used exploratory item-factor analysis to determine how items cluster across scales. After determining that a seven-factor solution was optimal, computerized adaptive testing (CAT) simulation was run to determine what would happen if the seven full-form factors were administered adaptively. These results were used to select items for short-form scales, producing seven final scales (items = 47). Validity was assessed by relating short-form scores to demographics, clinical diagnoses, scales, and criteria; these relationships were also compared to the relationships found with the original scales. Almost all effects detected by the twelve original scales were detected by the substantially abbreviated short-forms. The abbreviated battery shows promise for rapid assessment of multiple risk and resilience parameters, a necessity in large-scale studies.

Academic Self-Perceptions and Academic Achievement in Chinese Children: A Multiwave Longitudinal Study

This study examined reciprocal contributions between academic self-perceptions and academic achievement. Data were collected each year in four consecutive years from a sample of children in China (initial N = 1,156; 581 boys; initial M_age  = 9.33 years). Analyses using random intercept cross-lagged panel models revealed that the effects of academic achievement on self-perceptions tended to be more evident in lower grades and the effects of academic self-perceptions on achievement tended to be more evident in higher grades. Latent growth curve analyses showed that the initial level of academic self-perceptions and achievement moderated the growth of each other. The results indicate the contributions between academic self-perceptions and achievement that occur in a progressive cascading manner in Chinese children.

Assessing within- and between-family variations in an expanded measure of childhood adversity

Previous measures of childhood adversity have enabled the identification of powerful links with later-life wellbeing. The challenge for the next generation of childhood adversity assessment is to better characterize those links through comprehensive, fine-grained measurement strategies. The expanded, retrospective measure of childhood adversity presented here leveraged analytic and theoretical advances to examine multiple domains of childhood adversity at both the microlevel of siblings and the macrolevel of families. Despite the fact that childhood adversity most often occurs in the context of families, there is a dearth of studies that have validated childhood adversity measures on multiple members of the same families. Multilevel psychometric analyses of this childhood adversity measure administered to 1,194 siblings in 500 families indicated that the additional categories of childhood adversity were widely endorsed, and increased understanding of the sources and sequalae of childhood adversity when partitioned into within- and between-family levels. For example, multilevel confirmatory factor analyses (MCFAs) indicated that financial stress, unsafe neighborhood, and parental unemployment were often experienced similarly by siblings in the same families and stemmed primarily from family wide (between-family) sources. On the other hand, being bullied and school stressors were often experienced differently by siblings and derived primarily from individual (within-family) processes. Multilevel structural equation modeling (MSEM) further illuminated differential criterion validity correlations between these categories of childhood adversity with midlife psychological, social, and physical health. Expanded, multidomain, and multilevel measures of childhood adversity appear to hold promise for identifying layered causes and consequences of adverse childhood experiences.

Family Socioeconomic Status, Cortisol, and Physical Health in Early Childhood: The Role of Advantageous Neighborhood Characteristics

OBJECTIVE

Children from families with lower socioeconomic status (SES) evidence greater physiological dysregulation and poorer health. Despite recognition of environmental contributors, little is known about the influence of neighborhood characteristics. The present study examined the moderating role of community-level risks and resources on the relation of family SES to children's daily cortisol output and physical health during the kindergarten year.

METHODS

In fall and spring of kindergarten, children's (N = 338) daily total cortisol was measured and parents and teachers rated children's global physical health. Parents reported family SES. Neighborhood characteristics were assessed using the Child Opportunity Index, a population-level tool that evaluates the quality of multiple domains of neighborhood attributes.

RESULTS

In fall, children reared in lower SES family environments had higher cortisol when residing in lower quality (lower opportunity) neighborhoods (b = -.097, p < .001), but there was no relation between family SES and children's cortisol in more advantaged (higher opportunity) neighborhoods (b = -.023, p = .36). Lower family SES was prospectively associated with poorer physical health in spring (controlling for fall health) only among children living in lower opportunity neighborhoods (b = -.250, p = .018) and was unrelated to physical health among children residing in higher opportunity neighborhoods (b = .042, p = .70).

CONCLUSIONS

Higher opportunity neighborhoods may protect against the negative consequences of low family SES on children's stress physiology and physical health. Public health interventions that bolster neighborhood opportunities may benefit young children reared in socioeconomically disadvantaged family environments.

An Investigation of Relational Risk and Promotive Factors Associated with Adolescent Female Aggression

Despite growing trends in adolescent female aggression, much adolescent aggression research has focused on males to the exclusion of their female counterparts. Using relational-cultural and social role theories, the current study identifies the risk and promotive factors associated with adolescent female aggression. Using data from the Rural Adaptation Project (a 5 year longitudinal panel study of youth from two rural, ethnically diverse, low income counties in North Carolina), a 2-level hierarchical linear model was estimated (N = 3580). Internalizing symptoms, association with delinquent friends, peer pressure, and parent-child conflict emerged as risk factors whereas teacher support was a significant promotive factor. Results suggest that interventions should focus on negative relationships in both the parent and peer domains and underscore the need for mental health services for aggressive girls.

Effects of intrauterine substance and postnatal violence exposure on aggression in children

During the cocaine epidemic of the 1980s and early 1990s, many expressed fears that children with intrauterine cocaine exposure (IUCE) would grow up to be unusually violent. The present study examines the relationship of caregiver reports of school-age children's aggressive behavior with IUCE and postnatal exposure to violence. Respondents were 140 low-income, primarily African American children, ages 8-11, and each child's current primary caregiver from a longitudinal study evaluating potential long term sequelae of IUCE. Multiple regression analyses were used to investigate the independent and interactive effects of level of IUCE (None (n = 69), Lighter (n = 47), Heavier (n =  24)) and exposure to violence (Violence Exposure Scale for Children-Revised) on aggressive behavior (Child Behavior Checklist), while also controlling for other intrauterine substance exposures and additional contextual factors. Children's self-reported exposure to violence was significantly positively associated with caregivers' reports of aggressive behavior (β = 2.17, P = .05), as was concurrent caregiver's psychiatric distress (β = .15, P = .003). However, neither IUCE nor its interaction with exposure to violence showed a significant association with aggressive behavior. Findings suggest the importance of postnatal social environment rather than IUCE in predicting aggressive behavior in childhood.

Impact of Irritability and Impulsive Aggressive Behavior on Impairment and Social Functioning in Youth with Cyclothymic Disorder

OBJECTIVE

Research on adults with cyclothymic disorder (CycD) suggests that irritability and impulsive aggression (IA) are highly prevalent among this population. Less is known about whether these behaviors might also distinguish youth with CycD from youth without CycD. Additionally, little is known about how irritability and IA relate to one another, and whether they are associated with different outcomes. This study aimed to compare irritability and IA across diagnostic subtypes to determine whether CycD is uniquely associated with these behaviors, and to assess how irritability and IA relate to youth social and general functioning.

METHODS

Participants (n = 459), 11-18 years of age, were recruited from an urban community mental health center and an academic outpatient clinic; 25 had a diagnosis of CycD. Youth and caregivers completed measures of IA and irritability. Youth and caregivers also completed an assessment of youth friendship quality. Clinical interviewers assessed youth social, family, and school functioning.

RESULTS

Youth with CycD had higher scores on measures of irritability and IA than youth with nonbipolar disorders, but scores were not different from other youth with bipolar spectrum disorders. Measures of irritability and IA were correlated, but represented distinct constructs. Regression analyses indicated that irritability was related to friendship quality (p < 0.005). Both IA and irritability were related to social impairment (ps < 0.05-0.0005) and Child Global Assessment Scale (C-GAS) scores (ps = 0.05-0.005). CycD diagnosis was associated with poorer caregiver-rated friendship quality and social functioning (ps < 0.05).

CONCLUSIONS

We found that irritability and aggression were more severe among youth with CycD than among youth with nonbipolar diagnoses, but did not differ across bipolar disorder subtypes. Among youth seeking treatment for mental illness, irritability and IA are prevalent and nonspecific. Irritability and IA were uniquely related to our outcomes of social and general functioning, suggesting that it is worthwhile to assess each separately, in order to broaden our understanding of the characteristics and correlates of each.

School and peer influences on the academic outcomes of African American adolescents

Little scholarship explores how adolescents' beliefs about school and peers influence the academic outcomes of African American boys and girls. The sample included 612 African American boys (N = 307, Mage = 16.84) and girls (N = 305, Mage = 16.79). Latent class analysis (LCA) revealed unique patterns for African American boys and girls. Findings indicate that for African American boys, school attachment was protective, despite having peers who endorsed negative achievement values. Furthermore, socio-economic (SES) status was associated with higher grade point averages (GPA) for African American girls. Overall, these findings underscore the unique role of school, peer, and gendered experiences in lives of African American adolescents.

Reciprocal and Complementary Sibling Interactions: Relations with Socialization Outcomes in the Kindergarten Classroom

RESEARCH FINDINGS

To examine associations between sibling interaction patterns and later social outcomes in single- and two-parent families, 113 kindergarteners took part in naturalistic observations at home with siblings, classmates participated in sociometric interviews, and teachers completed behavior ratings. Sibling interactions were coded using a newly-developed 39-item checklist, and proportions of complementary and reciprocal sibling interactions computed. Complementarity occurred more among dyads where kindergartners were with toddler or infant siblings than among kindergartners with older or near-age younger siblings. Higher levels of complementarity predicted lower levels of internalizing but were not related to externalizing problems. Kindergartners' sociometric status in the classroom differed as a function of sibling interaction patterns, with neglected and controversial children experiencing less complementarity/more reciprocity than popular, average, and rejected children. Finally, there was some evidence for differential associations of sibling interaction patterns with social outcomes for children in single- versus two-parent families: regressions testing interaction effects show sibling reciprocity positively associated with kindergartners' social skills only in single-parent families, and complementary sibling interactions positively related to internalizing problems only in two-parent families.

IMPLICATIONS FOR PRACTICE

Those working with divorcing or other single-parent families might consider sibling interactions as a potential target for social skill building.

Chronic bullying victimization across school transitions: the role of genetic and environmental influences

We investigated the antecedents and consequences of chronic victimization by bullies across a school transition using a genetically sensitive longitudinal design. Data were from the Environmental Risk Longitudinal Twin Study (E-Risk), an epidemiological cohort of 2,232 children. We used mothers' and children's reports of bullying victimization during primary school and early secondary school. Children who experienced frequent victimization at both time points were classed as "chronic victims" and were found to have an increased risk for mental health problems and academic difficulties compared to children who were bullied only in primary school, children bullied for the first time in secondary school, and never-bullied children. Biometric analyses revealed that stability in victimization over this period was influenced primarily by genetic and shared environmental factors. Regression analyses showed that children's early characteristics such as preexistent adjustment difficulties and IQ predicted chronic versus transitory victimization. Family risk factors for chronic victimization included socioeconomic disadvantage, low maternal warmth, and maltreatment. Our results suggest that bullying intervention programs should consider the role of the victims' behaviors and family background in increasing vulnerability to chronic victimization. Our study highlights the importance of widening antibullying interventions to include families to reduce the likelihood of children entering a pathway toward chronic victimization.

Teacher-student interactions and attachment states of mind as predictors of early romantic involvement and risky sexual behaviors

Adolescents' capacities to negotiate sexual behavior in romantic relationships have important implications for their reproductive and health outcomes. This study examined adolescents' interactions with teachers and attachment states of mind as predictors of their romantic involvement and risky sexual behavior in an economically disadvantaged sample. Negative interactions with teachers predicted increased sexual risk-taking behaviors and females' early romantic involvement. Preoccupied states of mind increased risk for early romantic involvement and the likelihood that females would engage in risky sexual behavior. The findings demonstrate how adolescents' school experiences contribute to adaptation in romantic relationships in mid to late adolescence above and beyond representations of parent-child attachment.

Pregnancy and mental health of young homeless women

Pregnancy rates among young women who are homeless are significantly higher than rates among housed young women in the United States (J. M. Greene & C. L. Ringwalt, 1998). Yet, little research has addressed mental health or risk and resilience among young mothers who are homeless. Based on a sample from the Midwest Longitudinal Study of Homeless Adolescents, this study explores pregnancy and motherhood in unaccompanied homeless young women over a period of 3 years. The data are supplemented by in-depth interviews with a subset of young women. Results show that almost half (46.4%) of sexually active young women who are homeless (n=222, M age = 17.2) had been pregnant at baseline. Among those who stated they had children between Waves 2 and 13 (n=90), only half reported caring for their children consistently over time, and one fifth reported never seeing their children. Of the participants with children in their care at the last interview (Wave 13), almost one third met criteria for lifetime major depressive episode, lifetime posttraumatic stress disorder, and lifetime drug abuse, and half met criteria for lifetime antisocial personality disorder. Twelve-month diagnoses are also reported. The impacts of homelessness on maternal and child outcomes are discussed.

Adolescent attachment and trajectories of hostile-impulsive behavior: implications for the development of personality disorders

Adolescents' trajectories of impulsive and hostile behaviors provide a dynamic index of risk for the emergence of Cluster B (antisocial and borderline) personality disorders in early adulthood. In the current study, we tested the hypothesis that preoccupied states of mind in the Adult Attachment Interview would increase both the level and rate of growth in adolescents' trajectories of aggressive and sexual risk-taking behaviors measured at ages 13, 15, and 17. Overall, preoccupied states of mind predicted higher levels of sexual risk taking and aggressive behaviors across all three assessments as well as higher rates of growth in sexual-risk taking and caregiver-reported aggression over time. In addition, preoccupied females showed slower rates of decline in self-reported hostile emotions than did preoccupied males. The effects of gender as a moderator of the relations between preoccupied status and risk trajectories for personality disorders are discussed.

Mediators of neighborhood influences on externalizing behavior in preadolescent children

This study tested a mediation model of neighborhood influences on children's externalizing behavior. In the proposed model, neighborhood disadvantage, ethnic heterogeneity, and low residential stability affect children's behavior indirectly through their impact on neighborhood social processes, which in turn influence parenting and deviant peer affiliations. A community sample of 704 preadolescents (76% African American, 22% Caucasian) and their parents and teachers provided information for the study. Neighborhood concentrated poverty, derived from the 2000 U.S. Census, was positively associated with children's externalizing behavior. This effect was fully mediated by neighborhood social processes and parenting quality, while deviant peer affiliations made independent contributions to problem behavior. The final mediation model explained children's externalizing behavior equally well across gender and ethnicity, suggesting the presence of universal processes.

Neighborhood socioeconomic status effects on adolescent alcohol outcomes using growth models: exploring the role of parental alcoholism

OBJECTIVE

There is conflicting evidence regarding the impact of neighborhood socioeconomic status (SES) on adolescent alcohol use. The current study tested whether the prospective effects of neighborhood SES on adolescent alcohol outcomes varied across parental alcoholism subgroups.

METHOD

Data from a group of adolescents (N=361) from an ongoing longitudinal study of children of alcoholics (COAs) and matched controls were collected at three initial annual assessments. Latent growth models were estimated with a range of related time-invariant and time-varying predictors.

RESULTS

Among non-COAs, higher neighborhood SES predicted increased rates in alcohol use and consequences, whereas among COAs, lower neighborhood SES was predictive of increased rates in alcohol use and marginally predicted rates of consequences. There were also time-specific effects of family mobility on alcohol outcomes.

CONCLUSIONS

The current study provides evidence for differential effects of neighborhood SES on adolescent alcohol use and consequences for non-COAs and COAs. The group differences found in this study may help explain the equivocal findings from previous neighborhood studies, which may use samples with an unmeasured mix of high- and low-risk adolescents. Future research should identify pathways to alcohol use and problems for high- and low-risk adolescents living in neighborhoods that span the range of the socioeconomic spectrum.

Conduct disorder in girls: neighborhoods, family characteristics, and parenting behaviors

BACKGROUND

Little is known about the social context of girls with conduct disorder (CD), a question of increasing importance to clinicians and researchers. The purpose of this study was to examine the associations between three social context domains (neighborhood, family characteristics, and parenting behaviors) and CD in adolescent girls, additionally testing for race moderation effects. We predicted that disadvantaged neighborhoods, family characteristics such as parental marital status, and parenting behaviors such as negative discipline would characterize girls with CD. We also hypothesized that parenting behaviors would mediate the associations between neighborhood and family characteristics and CD.

METHODS

We recruited 93 15-17 year-old girls from the community and used a structured psychiatric interview to assign participants to a CD group (n = 52) or a demographically matched group with no psychiatric disorder (n = 41). Each girl and parent also filled out questionnaires about neighborhood, family characteristics, and parenting behaviors.

RESULTS

Neighborhood quality was not associated with CD in girls. Some family characteristics (parental antisociality) and parenting behaviors (levels of family activities and negative discipline) were characteristic of girls with CD, but notll. There was no moderation by race. Our hypothesis that the association between family characteristics and CD would be mediated by parenting behaviors was not supported.

CONCLUSION

This study expanded upon previous research by investigating multiple social context domains in girls with CD and by selecting a comparison group who were not different in age, social class, or race. When these factors are thus controlled, CD in adolescent girls is not significantly associated with neighborhood, but is associated with some family characteristics and some types of parental behaviors. However, the mechanisms underlying these relationships need to be further investigated. We discuss possible explanations for our findings and suggest directions for future research.

Negative peer perceptions of obese children in the classroom environment

OBJECTIVE

It is asserted that the more immediate and observable consequences of pediatric obesity are psychosocial in nature. This study examines the peer relations of clinically referred obese youth compared to demographically comparable nonoverweight peers within the classroom environment.

METHODS AND PROCEDURES

Peer-, teacher-, and self-reports of behavioral reputation (Revised Class Play (RCP)), and peer reports of social acceptance, nonsocial attributes (attractiveness, athleticism, academic competence), and health interference (school absence, illness, fatigue) were obtained regarding 90 obese youth (BMI > 95th percentile; 8-16 years, 57% girls, 50% African American) and 76 nonoverweight demographically similar comparison classmates.

RESULTS

Relative to comparison peers, obese children were nominated significantly less often as a best friend and rated lower in peer acceptance, although the two groups did not differ in the number of reciprocated friendships. Obese youth were described by peer, teacher, and self-report as more socially withdrawn and by peers as displaying less leadership and greater aggressive-disruptive behavior. Peers also described obese youth as less physically attractive, less athletic, more sick, tired, and absent from school. Being seen as less attractive and less athletic by peers helped to explain differences in obese and nonoverweight youth's levels of peer acceptance.

DISCUSSION

Clinically referred obese youth are characterized by peer relations that differ from those of nonoverweight youth. The peer environment provides a rich context to understand the social consequences of pediatric obesity as well as factors that could be targeted in intervention to promote more positive health and psychosocial outcomes.

Do the predictors of child conduct problems vary by high- and low-levels of socioeconomic and neighborhood risk?

This review seeks to examine whether the existing literature on child conduct problems (CP) supports the notion that certain CP risk factors vary in their importance across disadvantaged and better-off environments. Disadvantaged environments are represented by socioeconomic and/or neighborhood risk (SN risk) in this review. Three types of studies were reviewed: behavioral genetic studies that compare the importance of genetic and environmental influences on CP for youth from poor homes and/or disadvantaged communities versus youth from better-off contexts, studies that examine how SN risk and other CP risk factors interact, and studies that compare the antecedents for CP across levels of SN risk. Findings were inconsistent about the manner in which individual child risk factors interact with SN risk. However, familial risk factors were generally found to be of greater importance for youth from poor families and disadvantaged communities, particularly parental supervision. Most of the studies that indicated otherwise focused on physical discipline, or were limited to children from disadvantaged and extremely deprived environments. The findings suggest that in extremely deprived environments, familial influences are overwhelmed by the pervasiveness of other CP risk factors such as deviant peers. Implications for intervention and suggestions for future research are discussed.

Risk factors for boy's conduct problems in poor and lower-middle-class neighborhoods

The joint trajectory analysis version of Nagin's (Group-based modeling of development. Cambridge, MA: Harvard University Press, 2005) semiparametric, group-based approach for modeling trajectories was used to assess how boy's trajectories of conduct problems (CP) and neighborhood SES covaried from ages 5 to 12. Participants were recruited from Women, Infants, and Children clinics when they were 18 months old. Subsequent analyses examined whether boys from poor and more prosperous neighborhoods differed in the degree to which they were exposed to familial risk factors for CP during early childhood and the extent to which risk factors for CP were generalizable across communities. Findings revealed a small, but positive relationship, between boy's trajectories of CP and neighborhood SES. In addition, chronic CP boys from more prosperous communities were found to have more child/individual risk factors for CP than their counterparts from poorer communities. Implications for prevention and intervention are discussed.

Aggression at age 5 as a function of prenatal exposure to cocaine, gender, and environmental risk

OBJECTIVE

To examine childhood aggression at age 5 in a multiple risk model that includes cocaine exposure, environmental risk, and gender as predictors.

METHODS

Aggression was assessed in 206 children by using multiple methods including teacher report, parent report, child's response to hypothetical provocations, and child's observed behavior. Also examined was a composite score that reflected high aggression across contexts.

RESULTS

Multiple regression analyses indicated that a significant amount of variance in each of the aggression measures and the composite was explained by the predictors. The variables that were independently related differed depending on the outcome. Cocaine exposure, gender, and environmental risk were all related to the composite aggression score.

CONCLUSIONS

Cocaine exposure, being male, and a high-risk environment were all predictive of aggressive behavior at 5 years. It is this group of exposed boys at high environmental risk that is most likely to show continued aggression over time.

Is neighborhood context differently related to externalizing problems and delinquency for girls compared with boys?

Although a number of reviews of gender differences in conduct problems and delinquency exist, this paper fills a gap in reviewing neighborhood influences on gender differences in conduct problems and delinquency. These influences are known to be important for boys in childhood and adolescence, but cannot be assumed to be influential in the same manner for girls. The paper starts with several conceptualizations of the association between gender, neighborhoods and juvenile delinquency. It then addresses 4 key questions. Is residing in a disadvantaged neighborhood associated with problem behavior in girls? Are neighborhood effects independent of girls' age? Are girls in disadvantaged neighborhoods exposed to more risk factors than girls in advantaged neighborhoods? Can mediating risk factors explain gender differences in neighborhood effects on children's and adolescents' conduct problems and delinquent behavior? Answers to these questions are important to steer research and elucidate aspects of interventions that can be optimized for girls.

A biopsychosocial model of the development of chronic conduct problems in adolescence

A biopsychosocial model of the development of adolescent chronic conduct problems is presented and supported through a review of empirical findings. This model posits that biological dispositions and sociocultural contexts place certain children at risk in early life but that life experiences with parents, peers. and social institutions increment and mediate this risk. A transactional developmental model is best equipped to describe the emergence of chronic antisocial behavior across time. Reciprocal influences among dispositions, contexts, and life experiences lead to recursive iterations across time that exacerbate or diminish antisocial development. Cognitive and emotional processes within the child, including the acquisition of knowledge and social-information-processing patterns, mediate the relation between life experiences and conduct problem outcomes. Implications for prevention research and public policy are noted.

Control beliefs as a mediator of the relation between stress and depressive symptoms among inner-city adolescents

Adolescents' control beliefs were examined as a mediator of the relation between stress and depressive symptoms among a diverse sample of 445 inner-city adolescents. Results indicated that control beliefs significantly mediate the relation between stress and depressive symptoms. The specific direct effects of six individual stress domains (peer, family, school, neighborhood, economic, discrimination) on control beliefs and depressive symptoms were also examined. Results showed that (1) economic stress relates to adolescents' control beliefs, (2) family stress relates to adolescent depressive symptoms, and (3) peer stress relates to both control beliefs and depressive symptoms. Secondary analyses revealed that control beliefs significantly mediate the specific relations between peer stress and depressive symptoms. Results were not found to vary across ethnic groups. The implications of these findings for adolescent mental health and preventive interventions targeting depression are discussed.

Neighborhood contextual factors and early-starting antisocial pathways

This paper examines research investigating the effects of neighborhood context on the onset and persistence of early-starting antisocial pathways across middle and late childhood. The review begins by presenting theory and research mapping the early-starting developmental pathway. Next, sociologically and psychologically based investigations linking neighborhood context and early antisocial behavior are examined, in order to posit and evaluate the effects of community economic disadvantage, exposure to neighborhood violence, and involvement with neighborhood-based deviant peer groups on the development of antisocial behavior. It is suggested that middle childhood may represent a critical developmental period during which children are at heightened risk for neighborhood-based effects on antisocial behavior problems. Key methodological issues are addressed, and recommendations for future research integrating developmental pathways and neighborhood theory and research are advanced.

Predicting developmental outcomes at school entry using a multiple-risk model: four American communities. The Conduct Problems Prevention Research Group

The contributions of different risk factors in predicting children's psychological and academic outcomes at the end of 1st grade were examined. Using a regression model, levels of ecobehavioral risk were assessed in the following order: specific demographics, broad demographics, family psychosocial status, mother's depressive symptoms, and neighborhood quality. Participants were 337 families from 4 American communities. Predictor variables were assessed in kindergarten, and teacher, parent, and child outcomes (behavioral and academic) were assessed at the end of 1st grade. Results indicated that (a) each level of analysis contributed to prediction of most outcomes, (b) 18%-29% of the variance was predicted in outcomes, (c) a common set of predictors predicted numerous outcomes, (d) ethnicity showed little unique prediction, and (e) the quality of the neighborhood showed small but unique prediction to externalizing problems.
