Pervasive developmental disorders, psychiatric comorbidities, and the law

Scattered reports propose that pervasive developmental disorders (PDDs) are risk factors for criminal behavior, yet the association between PDD and delinquent behavior is untrue for the majority of patients. However, individuals with PDDs may be at risk for legal trouble in the presence of comorbid psychopathology, and not solely on the basis of their developmental disability. This article analyzes theoretically the relationship between complex developmental disorders and delinquency with the hypothesis that the delinquent behaviors reported in it resulted from comorbid psychopathology and not as a direct consequence of a developmental disorder. A small series of patients diagnosed with a PDD and comorbid psychiatric illnesses whose admission to the hospital was precipitated by delinquent behavior is presented.     

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.     

Juvenile delinquency and victimization: a theoretical typology

It is a widely voiced notion that juvenile delinquency and victimization co-occur extensively in the youth population, in particular because delinquent youth engage in risky activities. But theory from the bullying and traumatic stress literatures suggests that there may be additional pathways by which delinquency and victimization are connected. This analysis looks for possible subtypes of delinquents and victims consistent with such pathways. Using the Developmental Victimization Survey, a national sample of 1,000 youth aged 10 to 17 were interviewed over the phone. Support emerges for three distinct types of delinquent-victims, who are termed bully-victims, delinquent sex/maltreatment- victims, and property delinquent-victims. There is also evidence for substantial groups of youth who are primarily delinquent but not seriously victimized, as well as youth who are primarily victimized but not delinquent.     

DELINQUENT PEERS IN CONTEXT: A LONGITUDINAL NETWORK ANALYSIS OF SELECTION AND INFLUENCE EFFECTS*

In this article, longitudinal social network data are analyzed to get a better understanding of the interplay between delinquent peers and delinquent behavior. These data contain detailed information about the social networks of secondary school students from the same grade, their delinquent behavior, and many relevant correlates of network formation and delinquency. To distinguish selection and influence processes, a method (Simulation Investigation for Empirical Network Analyses, SIENA) is used in which network formation and changes in delinquency are simulated simultaneously within the context of other network processes and correlates of delinquency. The data and the method used make it possible to investigate an unusually wide array of effects on peer selection and delinquent behavior. The results indicate that similarity in delinquency has no significant effect on the selection of school friends when other network dynamics are taken into account. However, the average delinquency level of someone's friends in the school network does have a significant, although relatively small, effect on delinquent behavior of the respondents, beyond significant effects of changes in the level of self‐control and morality. Another peer‐related change, leaving or joining informal street‐oriented youth groups, also appears to have a substantial effect on changes in delinquency.     

THE CONTRIBUTION OF GANG MEMBERSHIP TO DELINQUENCY BEYOND DELINQUENT FRIENDS*

Both being involved in a gang and having friends who are delinquent have been shown to contribute to an individual's own delinquency. However, the unique contribution of gang membership to delinquency, above and beyond having delinquent peers, has not been well studied. Increased delinquency among gang members may not be due to gang membership per se, but to the members' association with delinquent peers. Using data from the Seattle Social Development Project, this research compared involvement in delinquency for gang members, nongang youths with delinquent friends, and nongang youths who did not have delinquent friends. MANOVA and follow-up ANOVA were conducted to determine differences on measures of delinquency among the three groups at ages 14 and 15. Gang members were found to have a higher rate of offending in the past year when compared with the other groups. The contribution of gang membership to delinquency above and beyond having delinquent friends was also examined using structural equation modeling. Gang membership was found to independently predict both self-reported and officially recorded delinquency beyond the effects of having delinquent friends and prior delinquency. Implications of the results for delinquency prevention and intervention efforts are discussed.     

THE INTERACTIVE EFFECTS OF PEER VARIABLES ON DELINQUENCY

Drawing on relevant theory and research, it is argued that the impact of delinquent peers on delinquency is conditioned by (1) attachment to peers, (2) time spent with peers, and (3) the extent to which peers present delinquent patterns (i.e., present definitions favorable to delinquency, model delinquent behavior, and differentially rein force delinquency). Regression analyses with data from the National Youth Survey provide partial support for these arguments. When the above variables are at their mean or lower levels, a measure of association with peers who engage in serious delinquency has no impact or a negative impact on delinquency. When the above variables are at higher levels, delinquent peers (serious) has a strong, positive impact on delinquency. A measure of association with peers who engage in minor delinquency, however, is not conditioned by the above variables.     

School Characteristics,Strain, and Adolescent Delinquency: a Test of Macro-Level Strain Theory in China

Despite the important role of schools in influencing juvenile delinquency, limited research has investigated the contextual effects of schools on delinquency. Using the framework of macro-level strain theory, this study investigates the effects of school-level strain on delinquent behavior among Chinese adolescents. The sample comprises 1411 adolescents from 32 middle schools in Guangzhou, a large city in Southern China. Results from multilevel regression models show that school-aggregated level of strain is positively associated with both self-destructive and other-directed delinquent behaviors, after adjusting for individual strain and other sociodemographic variables. Specifically, school-level anticipated educational goal blockage and negative treatment by teachers are positively associated with self-destructive behavior, whereas school mean level of negative treatment by peers is positively related to other-directed behavior. Although individual-level strain is positively associated with both types of delinquency, it only partially mediates the effect of school-level strain on self-destructive delinquent behavior. This study also investigates whether school-level variables may condition the strain-delinquency relationship. The results show a significant interaction between personal strain and overall delinquent schoolmates on both self- and other-directed delinquent behaviors, indicating that school-level delinquent peers significantly exacerbate the effect of strain on delinquent behaviors. These findings suggest that the effort to reduce juvenile delinquency should target practices to alleviate both individual strain and aggregate strain, and provide more resources and support for students, particularly those in schools with substantial disruptive student behaviors, to legitimately cope with strains.

     

Adolescent maltreatment, negative emotion, and delinquency: An assessment of general strain theory and family-based strain

This study used data from a national sample of youth (N = 1,423) to test hypotheses derived from Robert Agnew's (1992, 2001) general strain theory concerning the relationship between adolescent maltreatment and delinquent behavior. Specifically, it focused on the extent to which the effect of maltreatment on general delinquency, serious delinquency, and substance use was mediated by negative emotions in the form of anger, anxiety, and depression. Results lend partial support to the theory. Confirming the importance of parent-child problems as a source of strain leading to delinquency, findings from ordinary least squares regression models revealed a significant association between maltreatment and all three forms of delinquent behavior. Although findings also showed that negative emotions are key intervening mechanisms influencing the magnitude of the direct effect of strain, maltreatment continued to exert significant effects even after controlling for negative emotions and both individual and family characteristics.     

THE DYNAMICS OF DELINQUENT PEERS AND DELINQUENT BEHAVIOR*

This analysis examines the dynamic reciprocal relationship between delinquent peer associations and delinquent behavior. It tests the hypothesis, derived from learning and interactional theories, that delinquent peers and delinquent behavior are reciprocally related—delinquent peer associations foster future delinquency, and delinquency increases the likelihood of associating with delinquent peers. It also tests the competing hypothesis, derived from control theories, that delinquent peers do not cause delinquency, but instead, the relationship is (1) spurious due to individual criminal propensity, (2) a result of the effects of delinquent behavior on future associations with delinquent peers, or (3) an artifact of problems of measuring delinquent peers. To test these propositions, we use data from the National Youth Survey and estimate a cross-lagged panel model that corrects for measurement error in indicators of delinquent peers and delinquent behavior. The model species a covariance structure model for ordinal measures. Parameters are estimated by (1) estimating a threshold model relating ordinal measures to continuous latent variables; (2) estimating a matrix of polychoric correlations relating observed variables, and (3) using an asymptotic distribution-free estimator to estimate structural parameters. The results suggest that delinquent peer associations and delinquent behavior are reciprocally related, but the effect of delinquency on peer associations is larger than that of peer associations on delinquency.     

How Collaborative the Collaboration? Assessing Interagency Collaboration within a Juvenile Court Diversion Program

Juvenile delinquency with co‐occurring substance abuse and mental health disorders has become an increasing problem within the United States. In part this can be attributed to the excessive number of delinquent youth entering the juvenile justice system with untreated substance abuse and/or mental health disorders. In an effort to combat this problem, interagency collaborations have been formed to provide more effective treatment services. One such interagency collaboration is the JETS Program. This study identifies the strengths and limitations of establishing an interagency collaboration within the first year of a juvenile treatment court's inception.     

Part-time Jobs,Delinquency and Victimization Among Finnish Adolescents

Among lay people as well as among scholars it is sometimes assumed that adolescent work deters juvenile delinquency. In contrast, existing research suggests that there is a positive association between adolescent parttime work and delinquency. This study assesses this claim and examines in a nationally representative sample of 15-16-yearold Finnish adolescents ( n = 4347), the association between work during the school year and self-reported delinquency and victimization, and explore whether the possible associations are general or based on some subcategory of delinquent behaThere viour/victimization. The results of multivariate analyses indicate that intensive weekly working is significantly positively associated with delinquent behaviour. When gender, disposable allowances and various factors suggested by control, strain and differential association theories were controlled for, intensive work (10 hours or more remained a significant predictor of the following types of delinquency: beating up someone, driving without licence, buying stolen goods, vandalism at school and drunken driving. Intensive workers' likelihood of committing these acts were about two to per week) three times as high as nonworkers' likelihood of committing such acts. Intensive work was related to victimization only in bivariate models, suggesting that the work-victimization association does not reflect direct causation. In conclusion, intensive work appears to increase delinquent activity slightly. Although we do not argue that work is a major cause of delinquency in adolescence, we suggest caution against encouraging intensive work during the school year.     

YOUTH EMPLOYMENT AND DELINQUENCY: RECONSIDERING A PROBLEMATIC RELATIONSHIP*

Employment is often thought to discourage participation in crime, but self-report data from juveniles consistently disclose a positive correlation between employment and delinquency. This analysis tests three possible explanations for that correlation. The first is that differences in levels of delinquency between workers and nonworkers exist prior to employment. The second holds that working increases independence from parents, thereby reducing the controlling effect of parental influence. The third explanation, drawing on Sutherland's theory of differential association, is that employment increases delinquent behavior by exposing adolescents to a wider network of peers, including delinquent peers. Analysis of data from waves 1, 2, and 3 of the National Youth Survey reveals a positive association between employment and some forms of delinquency, especially alcohol and drug use. Selection bias explains much, but not all, of the association. Although no support is found for the parental influence explanation, the remaining employment effect is explained by exposure to delinquent peers.     

Life strain, negative emotions, and delinquency: An empirical test of general strain theory in the People's Republic of China

Using a sample of 615 middle school and high school students from both rural and urban areas of the People's Republic of China, this study tests the central hypotheses concerning the mediating model in Agnew's general strain theory. The analyses focus on the intervening mechanisms of negative emotions such as anger, resentment, anxiety, and depression that connect exposure to interpersonal strain with delinquent outcomes, including both serious delinquency and minor offenses. The results show that anger mediates the effect of interpersonal strain on violence, resentment mediates the effect of interpersonal strain on nonviolent delinquency, and anxiety and depression have a mediating effect on the relationships between interpersonal strain and minor offenses. The findings are generally consistent with the results of earlier studies in the United States.     

PEER SIMILARITY IN DELINQUENCY FOR DIFFERENT TYPES OF FRIENDS: A COMPARISON USING TWO MEASUREMENT METHODS*

Peer similarity in delinquency has been studied extensively. But basic questions remain about measuring peer delinquency and how important the nature of relationships with delinquent peers is. This article uses data from the NSCR School Project, which has collected unusually detailed information about delinquent peers and the social networks of adolescents. We examine differences in the roles of regular friends and best friends with regard to peer similarity in delinquent behavior. We also contrast two methods of measuring peer delinquency: the conventional one of asking respondents about their peers, and the social network method, by which peers report about themselves. The results show that respondents can have best and regular friends who differ in their degree of delinquency, and that the association between respondent and peer delinquency does not differ much between friends and best friends. At the same time, our results suggest that both types of peers influence the level of respondent delinquency. Measures based on the direct network method resulted in higher estimates of peer delinquency, but in lower estimates of the association between respondent and peer delinquency.     

Family Correlates of Male and Female Delinquency

This article examines sex differences in family bonds as a possible explanation of sex differences in self-reported delinquent behavior (SRD) among a national probability sample of 1725 adolescents. It was hypothesized that girls would report significantly stronger family bonds and significantly lower delinquency than boys. The findings provide limited support for these hypotheses. The expected sex differences in SRD were observed. males report significantly greater involvement in all forms of delinquent behavior. However, the expected sex differences in family bonds were not observed. Family bonds are modestly correlated with delinquency, but at comparable rates for males and females, and with evidence of their greater association among males in many cases. Theoretical and methodological explanations are suggested for the divergence of the observed findings from existing research.     

ADOLESCENT RESOURCES AND DELINQUENCY *

The dominant theories of delinquency tend to view the delinquent as a deprived individual who engages in delinquency because of forces beyond his or her control. This paper challenges that image, awing that many adolescents possess resources that increase their power and autonomy. This power and autonomy may be used to reduce social control and increase “Illegitimate means,” which in turn increase the likelihood of delinquency. Whether adolescents use their resources for delinquent ends is conditioned by several factors, most notably the adolescent's predisposition for delinquency, the benefits and costs of employing resources for delinquent ends in a particular situation, and the adolescent's perceived self-efficacy. Data from two nationally representative surveys of adolescents are used to analyze the relation between resources and delinquency among adolescents differing in their predisposition for delinquency. In most cases, resources are positively related to delinquency when the predisposition for delinquency is high.     

Racial composition,sentencing reforms,and rates of incarceration, 1970–1980

Association with delinquent peer groups is one of the most salient predictors of delinquent behavior. Despite the widespread documentation of these effects, little is known about whether the delinquent peer effect is conditioned by individual‐level characteristics. Using data from a multi‐wave survey of Mexican‐American adolescents, this study explored the interactive effect of susceptibility to peer influence and differential association with delinquent peers on delinquent outcomes. Results suggested that the delinquent peer effect on self‐reported delinquency is amplified when an adolescent is highly susceptible to peer influence. Analyses also indicated that this moderating effect varies according to offense seriousness. Specifically, the conditioning effect is most important when considering acts of serious delinquency.     

The Influence of Dating Relationships on Friendship Networks,Identity Development,and Delinquency

Prior research has documented general associations between dating and delinquency, but little is known about the specific ways in which heterosexual experiences influence levels of delinquency involvement and substance use. In the current study, we hypothesize that an adolescent's level of effort and involvement in heterosexual relationships play a significant role in forming the types of friendship networks and views of self that influence the likelihood of delinquency involvement and substance use. Analyses based on a longitudinal sample of adolescent youth (n = 1,090) show that high levels of dating effort and involvement with multiple partners significantly increases unstructured and delinquent peer contacts, and influences self‐views as troublemaker. These broader peer contexts and related self‐views, in turn, mediate the path between dating relationships, self‐reported delinquency, and substance use. Findings also document moderation effects: among those youths who have developed a troublemaker identity and who associate with delinquent peers, dating heightens the risk for delinquent involvement. In contrast, among those individuals who have largely rejected the troublemaker identity and who do not associate with delinquent friends, dating relationships may confer a neutral or even protective benefit. The analyses further explore the role of gender and the delinquency of the romantic partner.     

Sex differences in self-reported delinquency and official records: A multiple-group structural modeling approach

There has been a large increase in research in the last 10 years or so on the nature, extent, and causes of female delinquency, especially on how patterns differ from those of male delinquency. Few research efforts, however, have systematically examined sex differences in the reliability and construct validity of the most common technique used in causal research-the self—report method. The present study addresses this issue by empirically examining male-female differences in self-report reliabilities and the effect of the prevalence and incidence of delinquent behavior on official contact (i.e., arrest, court referrals). Multiple-group covriance structure models are employed to test hypotheses of measurement and structural invariance. The major conclusion is that while self-report measurement parameters (e.g., reliabilities) may differ, the structural link between the prevalence and incidence of delinquent behavior and official contact is generally invariant with respect to sex.     

DELINQUENT PEERS,BELIEFS, AND DELINQUENT BEHAVIOR: A LONGITUDINAL TEST OF INTERACTIONAL THEORY*

Three theoretical models of the interrelations among associations with delinquent peers, delinquent beliefs, and delinquent behavior are examined. The socialization model views delinquent peers and beliefs as causally prior to delinquent behavior, whereas the selection model hypothesizes that associations with delinquent peers and delinquent beliefs are a result of delinquent behavior. The interactional model combines aspects of both the socialization and the selection models, positing that these variables have bidirectional causal influences on one another over time. Data to test for reciprocal causality are drawn from three waves of the Rochester Youth Development Study. Results suggest that simple unidirectional models are inadequate. Associating with delinquent peers leads to increases in delinquency via the reinforcing environment of the peer network. Engaging in delinquency, in turn, leads to increases in associations with delinquent peers. Finally, delinquent beliefs exert lagged effects on peers and behavior, which tend in turn to “harden” the formation of delinquent beliefs.
