Evidence of Negligible Parenting Influences on Self‐Control,Delinquent Peers,and Delinquency in a Sample of Twins

Behavioral genetic findings continue to call into question the dominant role of parental influence. Utilizing a sample of twins from the National Longitudinal Study of Adolescent Health (Add Health), we assess the association between parenting behaviors and child self‐control, delinquent peer formation, and delinquency. Our results indicate that genetic influences and non‐shared environmental influences account for variation in these outcomes. We discuss these findings as they relate to theorizing about the role and function of parenting in the etiology of unique traits and behaviors.     

Genetic and environmental influences on the co-occurrence of early academic achievement and externalizing behavior

Purpose

Several studies have observed a relationship between academic achievement and externalizing behaviors, both of which are predictors of delinquency and criminal behavior in adulthood. There is, however, no consensus on an explanation for their co-occurrence. One perspective is that both emerge as a result of a common underlying factor. This study investigates the degree to which the same genetic and environmental factors account for the co-occurrence of these two outcomes.

Methods

The sample consists of twins (N = 360) from the Early Childhood Longitudinal Survey-Kindergarten Class of 1998-1999. Bivariate genetic analyses were conducted to assess the genetic and environmental influence on the relationship between academic achievement and externalizing behaviors during kindergarten.

Results

The covariation was due primarily to common shared environmental factors (55-87%), followed by common genetic (8-44%) and nonshared environmental factors (1-13%).

Conclusions

Both early academic achievement and externalizing behaviors are partially influenced by the same genetic and environmental factors. The large proportion of covariance attributed to shared environmental influences suggests that identifying and targeting shared environmental factors in prevention and intervention strategies may improve both behavior and academic achievement.     

A biosocial analysis of the sources of missing data in criminological research

Purpose

Failing to deal with missing data patterns effectively may result in biased parameter estimates and ultimately may produce inaccurate results and conclusions. The vast majority of criminological research has addressed this issue with listwise deletion (LD) and multiple imputation (MI) techniques. Identifying the specific covariates that directly contribute to patterns of missingness is highly important in deciding which technique to use. One of the more surprising omissions from the identified list of covariates is the potential role of genetic influences in the development of missingness.

Methods

The current study addresses this gap in the literature by estimating genetic (A), shared environmental (C), and the nonshared environmental (E) influences on missingness across measures of delinquency and self-control within a longitudinal sample of twin and sibling pairs.

Results

The results indicated that genetic influences explain a significant portion of the variance in missing values related to both delinquency and self-control.

Conclusions

Current methodological techniques aimed at addressing missing data should be amended to take genetic influences into account. Such modifications and the implications of the findings for future research are discussed.     

A longitudinal test of the revised strain theory

Agnew's (1985) revised strain theory argues that delinquency results from the inability to escape legally from painful or aversive situations. There is much indirect support for the theory, with experimental and survey data indicating that delinquency is associated with a wide variety of aversive situations. The experimental data, however, are of questionable generalizability and the survey data are primarily cross sectional in nature, leaving unresolved the issue of causal direction. This study examines the relationship between environmental adversity and delinquency using longitudinal data from a nationally representative sample of adolescent boys. A distribution-free method (arbitrary generalized least squares) is used to estimate a covariance structure model depicting a reciprocal relationship between adversity and delinquency. The results support the revised strain theory: environmental adversity has a causal effect on delinquency, but delinquency does not have an effect on adversity.     

A Genetic Basis of Economic Egalitarianism

Studies of political attitudes and ideologies have sought to explain their origin. They have been assumed to be a result of political values ingrained during the process of socialization until early adulthood, as well as personal political experience, party affiliation, social strata, etc. As a consequence of these environment-dominated explanations, most biology-based accounts of political preference have never been considered. However, in the light of evidence accumulated in recent years, the view that political attitudes are detached from any physical properties became unsustainable. In this paper, we investigate the origins of social justice attitudes, with special focus on economic egalitarianism and its potential genetic basis. We use Minnesota Twin Study data from 2008, collected from samples of monozygotic and dizygotic twin pairs (n = 573) in order to estimate the additive genetic, shared environmental, and unique environmental components of social justice attitudes. Our results show that the large portion of the variance in a four-item economic egalitarianism scale can be attributed to genetic factor. At the same time, shared environment, as a socializing factor, has no significant effect. The effect of environment seems to be fully reserved for unique personal experience. Our findings further problematize a long-standing view that social justice attitudes are dominantly determined by socialization.     

The influence of low self-control on violent and nonviolent delinquencies: a study of male adolescents from two Chinese societies

Low self-control is theorized to be a key correlate of delinquency. Using a nonadjudicated sample (N = 1057) from Hong Kong and Macau, the influence of self-control on self-reported violent and nonviolent delinquencies was investigated using Grasmick’s self-control scale. The influences of demographics and self-control on delinquency were also examined. Findings indicate that these adolescents are more likely to engage in overall delinquency, particularly violence, if they are older and if they are less educated. Age is the only demographic predictor of nonviolent delinquency. Risk-seeking behaviors and self-centeredness have significant influences on both violent and nonviolent delinquencies, while low frustration tolerance and preference for cognitive activities are only associated with an increased level of violent misconduct. These findings highlight the overall significant influence of self-control on adolescent delinquency in Chinese adolescents. Suggestions are offered to enhance adolescents’ self-control as a way to reduce their tendency to involvement in delinquent activities.     

Individual and contextual influences on delinquency: the role of the single-parent family

Research indicates that children are at risk for delinquency if they live in a single-parent family and if they live in areas with high levels of family disruption. Although there is a substantial amount of research on both the individual and aggregate relationships, examining delinquency at either of these two levels alone is not appropriate. Specifically, families do not exist in isolation as individual-level research inherently assumes, and aggregate research is concerned with explaining rates of delinquency as opposed to explaining influences on individual behavior. The current research used data from thirty-five schools, an important adolescent context, to determine the individual- and school-level effects of single-parent families on delinquency. The results from an overdispersed Poisson HLM regression model suggest both individual and aggregate effects, with a potential buffering effect of intact families regardless of any adolescents' specific family structure.     

Changing contexts: A quasi-experiment examining adolescent delinquency and the transition to high school

In a quasi-experiment, we examine whether changing schools during the transition from 8th to 9th grade influences adolescent delinquency, using a sample of more than 14,000 students in 26 public school districts (PROSPER study). The dataset follows students for eight waves from 6th through 12th grade and facilitates a unique, direct comparison of students who change schools with those who remain in the same school during this period. Results show that students who transition between schools report significantly less delinquency after the shift than those who do not, and that this difference persists through 10th grade. This decline is most pronounced when adolescents from multiple middle schools move to a single high school (i.e., multifeeder transitions). Students who transition between schools have fewer delinquent friends and participate in less unstructured socializing following the change in school environment, which partially mediates their reduced delinquency. Results provide some support for theories of differential association and routine activities. Our findings highlight the role of a crucial, yet understudied, life transition in shaping adolescent delinquency. The results from this quasi-experiment underscore the potential of alterations in social context to significantly dampen juvenile delinquency throughout high school.     

ADOLESCENT ROMANTIC RELATIONSHIPS AND DELINQUENCY INVOLVEMENT

While much attention has centered on the role of peer influence for adolescent delinquency, that of romantic partners has been largely neglected. Recent analyses of romantic relationships during the adolescent period suggest their general importance to development; research highlights that adolescents themselves frequently describe these relations as relatively intimate and influential. Thus, while classic theoretical frameworks such as differential association theory have often centered on the role of peers, their general logic is consistent with the notion that such relationships may indeed "matter" as a source of influence on delinquent behavior. Data from the National Longitudinal Study of Adolescent Health are well suited for examining the role of romantic partners because they allow for the identification and recreation of friendship networks and connections between romantic partners. Forging these interconnections, we link friends' and romantic partners' delinquency to respondents' own delinquency, enabling an examination of romantic partner influence on adolescent delinquency, beyond that influence associated with friends' behaviors. Drawing on theories of gender stratification, we also explore whether the effect of romantic partners' behavior is conditioned by gender. Findings reveal that romantic partners' delinquency exerts a unique effect on respondents' delinquency net of friends' delinquency and control variables. Additionally, romantic partners' deviance has a stronger effect on female involvement in minor deviance. We find no evidence, however, that gender conditions the strength of romantic partners' more serious delinquency on respondents' serious delinquency.     

Pubertal timing and adolescent delinquency†

Early pubertal timing (PT) increases the risk of adolescent delinquency, whereas late development reduces this risk; however, the mechanisms explaining PT effects on delinquency remain elusive. Theoretically, the PT–delinquency relationship is as a result of changes in parental supervision, peer affiliations, and body-image perceptions or is a spurious reflection of early life risk factors. Using intergenerational data from the Millennium Cohort Study, a prospective sample of children followed from infancy to age 14 years in the United Kingdom (N = 11,556 parent–child pairs), we find that for both boys and girls, early PT is associated with heightened risks of delinquency, relative to on-time puberty, whereas late PT is associated with lower risks, even after controlling for a large share of childhood confounders. Mediation test results indicate that changes in parental supervision, peer affiliations, and body-image perceptions from ages 11 to 14 partly account for associations between off-time PT and delinquency. Our findings are most consistent with criminological theories in which the psychosocial, familial, and peer group changes that accompany off-time pubertal development are emphasized. Changes in peer substance use, in particular, were the primary explanatory factor for the relationships between early and late PT and delinquency, for both boys and girls.     

Friendship Networks and Delinquency: The Relative Nature of Peer Delinquency

Although acknowledging the importance of adolescent friendships in the etiology of delinquency, prior studies have yet to provide a detailed examination of the role of actual friendship networks in delinquency. Using data from the National Longitudinal Study of Adolescent Health (1995–1996), this study's incorporation of friendship networks allows for a more rigorous conceptualization and measurement of peer delinquency based on carefully defined networks of adolescent friendships. Findings illustrate that friendship networks are very heterogenous in terms of members' participation in delinquent behavior with the majority of adolescents belonging to networks containing both delinquent and non-delinquent friends. In support of differential association's premise that delinquent behavior is influenced by the ratio of definitions favorable to those unfavorable to law violation (Sutherland, 1947), the proportion of delinquent friends in a respondent's network is most strongly associated with respondents' subsequent delinquency. This relative measure of peer delinquency is preferable to a measure of the absolute level of delinquency occurring by friends, the average delinquency committed by friends, or the absolute number of delinquent friends. Enmeshment in a friendship network where consensus about the appropriateness of delinquency is maximized (i.e., all friends are delinquent or non-delinquent) most effectively constrains the behaviors of network members to resemble the groups' behavior.     

The Influence of “Changing Directions” on the Self-Esteem of a Delinquent Population in a Correctional Setting

There is increasing evidence that low self-esteem is a possible basis for risk-taking behaviors such as substance abuse, sexual promiscuity, and juvenile delinquency. Thus, it has been hypothesized that by enhancing an adolescent?s self-image, a decrease in the incidence of such behaviors can be realized. The present study examines the effect of one secure juvenile facility's treatment program on adolescent self-esteem. The findings reflect the program's effectiveness with regard to self-esteem elevation. A follow-up study, to determine whether this heightened self-esteem is maintained and/or results in decreased delinquency is forthcoming.     

GENETIC AND ENVIRONMENTAL COMPONENTS OF ANTISOCIAL BEHAVIOR: A STUDY OF 265 TWIN PAIRS*

This study investigates the common-family environmental (CE), within-family environmental (WE), and hereditary (H) components of antisocial behavior and its correlates using a twin study design. The subjects are 265 adolescent twin pairs who reported in a mail survey on their antisocial behavior, deceitfulness, parental rejection (as perceived), anger, impulsivity, and value placed on school achievement. These six variables are intercorrelated in two ways: between-families (twin pairs' sums) and within-families (twin pairs' differences). The former covariance structure captures the twins' resemblances: the latter, the twins' differences in behavior. LISREL is used to model the observed relationships using structural equations containing CE, WE, and H factors. The best-fitting model requires only H and WE factors to explain the variables' relationships. Within this population, delinquent behavior is unaffected by CE influences such as social class, child rearing styles, parental attitudes, parental religion, and other factors equally affecting the twins. The principal genetic correlates of delinquency appear to be deceitfullness and temperamental traits.     

One Bad Apple May Not Spoil the Whole Bunch: Best Friends and Adolescent Delinquency

This study compared the association of adolescent delinquency with that of their best friend and remaining social network. Findings are reported from The National Longitudinal Study of Adolescent Health, a multi-wave nationally representative panel study of adolescents who were in grades 7–12 in 1994. Four delinquent outcomes were examined: Smoking, getting drunk, fighting, and a variety index of general delinquency. All analyses were replicated for three distinct criteria for identifying a “best friend.” We also examined several moderating factors and potential interrelationships between the best friend and remaining friendship group. Relative to the influence of the best friend, the influence of the remaining friendship group increased with group size, and with larger absolute disparities in delinquency levels between best and remaining friends. Our findings extend knowledge on the influence of best friends, and further underscore the importance of whether peer behaviors are measured directly (from the peers themselves) or indirectly (when focal respondents estimate the delinquent behavior of their peers).     

GENDER,FRIENDSHIP NETWORKS,AND DELINQUENCY: A DYNAMIC NETWORK APPROACH

Researchers have examined selection and influence processes in shaping delinquency similarity among friends, but little is known about the role of gender in moderating these relationships. Our objective is to examine differences between adolescent boys and girls regarding delinquency‐based selection and influence processes. Using longitudinal network data from adolescents attending two large schools in AddHealth (N = 1,857) and stochastic actor‐oriented models, we evaluate whether girls are influenced to a greater degree by friends’ violence or delinquency than boys (influence hypothesis) and whether girls are more likely to select friends based on violent or delinquent behavior than boys (selection hypothesis). The results indicate that girls are more likely than boys to be influenced by their friends’ involvement in violence. Although a similar pattern emerges for nonviolent delinquency, the gender differences are not significant. Some evidence shows that boys are influenced toward increasing their violence or delinquency when exposed to more delinquent or violent friends but are immune to reducing their violence or delinquency when associating with less violent or delinquent friends. In terms of selection dynamics, although both boys and girls have a tendency to select friends based on friends’ behavior, girls have a stronger tendency to do so, suggesting that among girls, friends’ involvement in violence or delinquency is an especially decisive factor for determining friendship ties.     

Reconsidering Peer Influences on Delinquency: Do Less Proximate Contacts Matter?

Much research on adolescent delinquency pivots on the notion of peer influence. The peer effect that is typically employed emphasizes the transmission of behaviors and attitudes between adolescents who are directly linked. In this paper, we argue that to rely solely on those direct social ties to capture peer influence oversimplifies the realities of adolescent society. We use data from the National Longitudinal Study of Adolescent Health to show that indirect peer relations can exercise independent influences on adolescent delinquency. Adolescents actively draw on the examples of friends of friends, and even more distal peers, as they develop their repertoires of action and identity. We argue, however, that this behavior actually reflects adolescents’ ongoing struggle to impress their closest friends and to preserve their social circle. Indeed, the extent to which adolescents are willing to model the behavior of indirect contacts seems to decline as that behavior becomes more dissimilar from that of their close friends. Our findings dovetail with an account of the adolescent as a rational actor who struggles for social acceptance in a complex peer environment which offers conflicting behavioral models.

Family negativity and delinquent behavior in adolescence: a predictive multivariate latent growth analysis

ABSTRACT

The current study had three aims: (1) to explore whether there is over-time change in adolescent delinquency and negativity in the parent–adolescent, sibling and marital relationships during adolescence; (2) to examine the interactions of negativity across subsystems; and (3) to examine whether levels and changes in adolescent delinquency are predicted by levels and changes in negativity in all family subsystems. Data of 497 families participating in the RADAR-young study were used. Ratings of all family members were used to measure negativity in family relationships, and adolescent self-report was used for delinquency. Multivariate latent growth curve models showed over-time increases in mother-adolescent negativity and over-time decreases in sibling negativity, as well as significant individual differences in these changes. Second, evidence for both social contagion and compensatory processes in family negativity was found. Third, initial levels of parent–adolescent negativity were related to initial levels but not over-time changes of adolescent delinquency, whereas initial levels of sibling negativity were related to over-time changes but not initial levels of adolescent delinquency. Finally, increases in parent–adolescent negativity were related to faster increases in adolescent delinquency, and decreases in sibling negativity were related to slower increases in adolescent delinquency. Implications of these results are discussed.     

EXPLAINING THE RELATIONSHIP BETWEEN EMPLOYMENT AND JUVENILE DELINQUENCY*

Most criminological theories predict an inverse relationship between employment and crime, but teenagers' involvement in paid work during the school year is correlated positively with delinquency and substance use. Whether the work–delinquency association is causal or spurious has been debated for a long time. This study estimates the effect of paid work on juvenile delinquency using longitudinal data from the national Monitoring the Future project. We address issues of spuriousness by using a two-level hierarchical model to estimate the relationships of within-individual changes in juvenile delinquency and substance use to those in paid work and other explanatory variables. We also disentangle the effects of actual employment from the preferences for employment to provide insight about the likely role of time-varying selection factors tied to employment, delinquency, school engagement, and leisure activities. Whereas causal effects of employment would produce differences based on whether and how many hours respondents worked, we found significantly higher rates of crime and substance use among nonemployed youth who preferred intensive versus moderate work. Our findings suggest the relationship between high-intensity work and delinquency results from preexisting factors that lead youth to desire varying levels of employment.     

Growing Up Poor: Examining the Link Between Persistent Childhood Poverty and Delinquency

Findings from aggregate-level and ethnographic research suggest that poverty and delinquency are related. The inability of individual-level quantitative research to demonstrate consistent evidence of this relationship, however, has been used to call into question whether poverty is indeed related to an increased propensity for delinquent involvement. This may be due to the difficulty individual-level analyses have in identifying the group most important in uncovering the relationship of poverty to delinquency—those individuals that experience persistent childhood poverty. This paper provides an assessment of the effects of both the level of exposure to poverty and its timing on delinquent involvement using fourteen years of longitudinal data for a national sample of younger adolescents. Findings indicate that exposure to poverty and the timing of such exposure are indeed related to an increased likelihood of involvement in delinquency.     

STRESSFUL LIFE EVENTS AND DELINQUENCY ESCALATION IN EARLY ADOLESCENCE*

A recent emphasis in criminology has been on trajectories, life transitions, and turning points that affect the escalation, stabilization, or desistance of deviant behavior. The purpose of this article is to describe and examine one potential pathway of delinquency escalation in early and mid-adolescence. It draws upon Agnew's general strain theory and research on adolescent stress to describe a significant transitory stage of the life course. A key organizing principle underlying the proposed pathway is that although stressful life events are highly variable among adolescents, experiencing a persistent or increasing number over time can lead to an escalation of delinquency. Using four years of sequential data from the Family Health Study (651 adolescents aged 11–14 during year one), we estimate a hierarchical growth-curve model that emphasizes the effects of life events on delinquency. The model assumes that delinquency is distributed as an overdispersed Poisson random variable. The results indicate that experiencing a relatively high number of life events over time is related to a significant “growth” of delinquency but that this relationship is not affected by sex, family income, self-esteem, or mastery.
