Delinquent Peer Group Formation: Evidence of a Gene X Environment Correlation

Emerging evidence suggests that variants of specific genes may influence some youths to seek out or associate with antisocial peers. Using genotypic data (N = 1,816) from the National Longitudinal Study of Adolescent Health (J. R. Udry, 1998, 2003), the authors tested this possibility. They found that the 10R allele of the dopamine transporter (DAT1) gene was associated with self-reported delinquent peer affiliation for male adolescents from high-risk environments (β range = .13-.14) despite controlling for delinquent involvement, self-control, and drug and alcohol use. The authors discuss the importance of using a biosocial framework to examine issues related to adolescent development.     

Attachment, parenting, and separation--individuation in adolescence: a comparison of hospitalized adolescents, institutionalized delinquents, and controls

The authors compared parent-related perceptions by hospitalized adolescents (i.e., who were admitted to a specialized psychiatric unit; n = 50) and delinquent adolescents (i.e., who were placed at a juvenile treatment institution; n = 51) with adolescents from the general population (n = 51). All adolescents completed a broad set of measures of attachment, perceived parenting, and separation-individuation. Contrary to initial expectations, hospitalized adolescents scored higher than controls on indices of excessive autonomy. Ambivalence regarding issues of interpersonal closeness and distance was found among delinquent adolescents. In addition, hospitalized and delinquent adolescents were found to be struggling, each in their specific way, with attachment-related experiences of trauma. Finally, delinquent adolescents also showed a stage-appropriate form of potentially adaptive narcissism. These findings add to the growing consensus in the literature that associations between adolescent psychopathology and parent-related perceptions are typically complex and somewhat counterintuitive.     

Male and female delinquency trajectories from pre through middle adolescence and their continuation in late adolescence

This study of male and female adolescent delinquency trajectories focuses on the prediction of late adolescence delinquency, based on earlier delinquency and social support. In this 3-wave longitudinal survey, 270 Dutch adolescents (113 males and 157 females) ages 12 to 14, were followed for a period of 6 years. For males, the level of delinquent activity in late adolescence strongly depends on earlier delinquent activities (R2 = .33, p < .0005). In contrast, the level of female delinquency in late adolescence is far less predictable (R2 = .18, p < .001), and could not be predicted from delinquent activities during pre and early adolescence, while support from the mother during late adolescence was associated with reduced delinquency for females. Different models may be needed to explain the development of delinquency for males versus females.     

Concept Shift and the Development of the Concept of Class in Children

The authors compared parent-related perceptions by hospitalized adolescents (i.e., who were admitted to a specialized psychiatric unit; n = 50) and delinquent adolescents (i.e., who were placed at a juvenile treatment institution; n = 51) with adolescents from the general population (n = 51). All adolescents completed a broad set of measures of attachment, perceived parenting, and separation–individuation. Contrary to initial expectations, hospitalized adolescents scored higher than controls on indices of excessive autonomy. Ambivalence regarding issues of interpersonal closeness and distance was found among delinquent adolescents. In addition, hospitalized and delinquent adolescents were found to be struggling, each in their specific way, with attachment-related experiences of trauma. Finally, delinquent adolescents also showed a stage-appropriate form of potentially adaptive narcissism. These findings add to the growing consensus in the literature that associations between adolescent psychopathology and parent-related perceptions are typically complex and somewhat counterintuitive.     

Effects of parenting,father absence,and affiliation with delinquent peers on delinquent behavior among African-American male adolescents

This study examined the effects of different aspects of parenting, father absence, and affiliation with delinquent peers on delinquent behavior in a cohort of African-American male adolescents. One round of survey data was collected from the youths' mothers or mother surrogates (N = 175) and two rounds of survey data were collected from the adolescents themselves. Analyses revealed that mothers' perceived control of sons' behavior was a deterrent of delinquent behavior, while other aspects of parenting (e.g., mother-son communication and relations) were not. The effect of mothers' perceived control was not mediated by adolescents' affiliation with delinquent peers. The effects of mothers' parenting variables and peer affiliation did not vary significantly by family structure, but socioeconomic disadvantage was more strongly associated with delinquent behavior in father-absent families. Though parenting effects were modest, this study suggests that African-American male adolescents are less likely to engage in delinquent behavior if they are closely monitored and supervised by their parents.     

The salience of the family in antisocial and delinquent behaviors among Spanish adolescents

The authors examined the relations between self-report measures of parental support, communication, and psychological control and measures of antisocial and delinquent behavior in a sample of 641 Spanish adolescents (M age = 14.35 years, SD = 1.53 years). Findings revealed similarities in the relations between parenting processes and both measures of deviant behavior. The results also demonstrated the need for researchers to consider the parenting effects of mothers and fathers independently. Specifically, maternal support was a negative predictor of antisocial and delinquent behaviors of male adolescents, and maternal psychological control was a positive predictor of antisocial and delinquent behaviors of female adolescents. Paternal parenting efforts did not account for additional variability.     

Early adolescent empathy, parental support, and antisocial behavior

In this two-wave prospective study, the authors investigated whether level of dispositional affective empathy moderated the association between parental support and antisocial behavior in early adolescents. The sample consisted of 823 Dutch boys and girls (mean age = 12.8 years) enrolled in the first year of secondary education. Higher levels of affective empathy were associated with less delinquent and aggressive behavior. Contrary to expectations, structural equation modeling did not indicate that youth with higher levels of affective empathy were susceptible to parental support. Further analyses showed that gender moderated the association between parental support and future delinquent and aggressive behavior. Only for girls, were high levels of parental support associated with lower levels of antisocial behavior.     

Self-concept and delinquency proneness

Contrary to the theory of the homeostatic model of self-concept, i.e., the expectancy that engaging in anti-social or pro-social behavior results typically in shifts in the self-concept (Graf, 1968; Deitz, 1970 shifts did not occur. Subjects, 12- 14-year-old boys enrolled in junior high school, delinquent prone (DP) and non-delinquent prone bright (NDPB), reacted to manipulation by engaging in reparative behavior as indicated via an aggression module in a fashion generally expected but the expected shift from chronic self-images did not occur. Both DP and NDPB viewed themselves similarly on self concept. The authors postulated that if shifts would occur for the delinquent prone it would be after they left school with its accompanying identification with a sub-culture outside the school setting.     

Longitudinal Associations Between Delinquent Behaviour of Friends and Delinquent Behaviour of Adolescents: Moderation by Adolescent Personality Traits

In this longitudinal study, we examined whether personality traits (parent‐rated Big Five personality traits) render some adolescents more susceptible than others to delinquent behaviour of friends, predicting rank‐order changes in adolescents' self‐reported delinquent behaviour. We examine susceptibility to both perceived (reported by adolescents) and self‐reported (reported by friends) delinquent behaviour of friends. Participants in this two‐wave study were 285 Dutch adolescents and their best friends. The adolescents (50% girls) were 15.5 years old on average (SD = 0.8 years), and their best friends (N = 176; 58% girls) were 15.1 years old (SD = 1.5 years). Perceived (but not self‐reported) delinquency of friends predicted a stronger increase in adolescent delinquency 1 year later, especially among adolescents low or average on conscientiousness. Emotional stability, agreeableness, extraversion and openness did not moderate associations between delinquency of friends and delinquency of adolescents. Our findings show that low conscientiousness serves as a risk factor, increasing vulnerability to perceived delinquent behaviour of friends, while high conscientiousness serves as a protective factor, increasing resilience to perceived delinquent behaviour of friends. Our findings also show that adolescents are susceptible to, and differ in susceptibility to, friends' delinquent behaviour as they perceive it—not to delinquent behaviour as reported by friends themselves.

Association with Delinquent Peers: Intervention Effects for Youth in the Juvenile Justice System

Although association with delinquent peers is a recognized precursor to ongoing delinquency problems, youth in the juvenile justice system are commonly prescribed intervention services that aggregate delinquent youth. However, little is known about the process variables that mediate the relationship between aggregating youth in intervention settings and poor subsequent outcomes. We examined data from two randomized intervention trials (one male sample and one female sample) with delinquent adolescents placed either in Multidimensional Treatment Foster Care (MTFC) or in group care. Path analyses suggested that the MTFC youth had fewer associations with delinquent peers at 12 months than did the group care youth. Further, associating with delinquent peers during the course of the intervention mediated the relationship between group condition and 12-month delinquent peer association. Implications for the development of interventions with delinquent youth are discussed.     

Family as a factor in delinquency

50 adjudicated delinquents were given academic and psychological tests and a self-report of delinquency according to the learning disability/delinquency study of the National Criminal Justice Service of 1980. 31 learning disabled delinquents were identified. The test of proportions compared learning disabilities in delinquent (n = 31) and nondelinquent (ns = 24 and 43) samples. The Mann-Whitney U test compared the reported number of categories of delinquent behavior in the three groups. A typical delinquent of this rural area tends to be a white male with average or above intelligence and a learning disability. His family is large; his parents are divorced. He comes from a poorer economic and cultural background. A dysfunctional family can be a center wherein delinquency grows; on the other hand, a strong family can nurture and protect when peers and school fail.     

Female adolescent friendship and delinquent behavior

Young female offenders (n = 29) and female high school students (n = 47) were compared in terms of delinquent behavior and relationships with their best female friend and peer group. Young offenders exhibited significantly more delinquent behavior than did high school students in the past year. Delinquents and nondelinquents did not significantly differ in amount of companionship, conflict, help, security, and closeness with their best female friend, and amount of trust, alienation, and perceived intimacy in their peer group. Less communication and more perceived peer pressure in the peer group distinguished delinquent females from nondelinquent females. Perceived peer pressure significantly predicted delinquent behavior in female adolescents. In short, friendships of delinquent and nondelinquent female adolescents are essentially similar despite higher levels of peer pressure among delinquents.     

Deviancy and Normative Training Processes in Experimental Groups of Delinquent and Nondelinquent Male Adolescents

The goal of this study was to identify the predictors and the moderators of group characteristics that influence deviancy and normative training processes in delinquent male adolescents. The authors experimentally tested the effects of group composition on deviant talk interaction processes among groups in which all members presented delinquent behaviors (“pure” delinquent group condition), those that included adolescents with no delinquent behaviors (“pure” normative group condition), and adolescents with both profiles (“mixed” group condition). Participants were 70 male adolescents aged 15–18 (M = 16.5; 56% Caucasian), with a random assignment to groups. Data were collected among three group sessions (T1, T2, T3), one session a week, using videotape. Two contents of interactions were also measured: antisocial and normative stories, counterbalanced across sessions. Results showed a significant group effect for antisocial talk and its reinforcement, with less antisocial talk within the mixed group condition in comparison to the pure delinquent group condition. The topic of interaction was also observed as a predictor of antisocial talk, with less normative interactions and more antisocial talk associated with antisocial topics. Finally, time moderated some relations between experimental groups and talk. We conclude with a discussion of the implications of this work for future research on deviancy training processes. Aggr.

Personality and group influences on self-reported delinquent behaviour

The results of two data sets (n=217 and n=209) are reported in which the links between the Eysenckian personality factors (psychoticism, extraversion, and neuroticism), identification with delinquent peers, and self-reported delinquency among high school students are examined. The factor structure of a delinquent identity measure is reported in Study 1 and partly confirmed in Study 2, suggesting at least two stable components: delinquent companionship and delinquent behavioural norms. Both of these measures were found to possess concurrent validity. Results from both samples showed that these factors, as well as psychoticism, made significant contributions to explaining self-reported delinquency. The results are discussed with reference to social identity theory and the nature of (Eysenckian) psychoticism.     

Decision-Making and Interaction by Families with and without A Drug-Abusing Child

As part of a larger study, the authors replicated Ferreira and Winter's ( 2 ) study of family interaction and decision-making using families with a drug-abusing child. Ferreira and Winter compared normal families and families with a child diagnosed as schizophrenic, delinquent, or maladjusted.     

Episodic and semantic contributions to older adults' autobiographical recall

The authors examined episodic and semantic contributions to 2 salient features of older adults' autobiographical recall: the reminiscence bump and the retention effect. Forty well-educated and healthy older men (mean age = 72.5 years; SD = 1.1) recalled personal memories in response to a series of cue words. They also categorized each memory as something they remembered from the past (R response) or they knew had happened in the past (K response) and indicated their ages when each memory occurred. The authors assumed that R and K responses reflected the operation of the episodic and semantic memory systems, respectively. Results showed a reminiscence bump and a retention effect for both R and K responses. The authors discuss the implications of this finding concerning the purported bases of the reminiscence bump and the retention effect as well as the notion that aging is more likely to effect episodic memory than semantic memory.     

Severity of Emotional and Behavioral Problems Among Poor and Typical Readers

The purpose of this study was to examine the severity of behavioral and emotional problems among adolescents with poor and typical single word reading ability (N = 188) recruited from public schools and followed for a median of 2.4 years. Youth and parents were repeatedly assessed to obtain information regarding the severity and course of symptoms (depression, anxiety, somatic complaints, aggression, delinquent behaviors, inattention), controlling for demographic variables and diagnosis of ADHD. After adjustment for demographic variables and ADHD, poor readers reported higher levels of depression, trait anxiety, and somatic complaints than typical readers, but there were no differences in reported self-reported delinquent or aggressive behaviors. Parent reports indicated no differences in depression, anxiety or aggression between the two groups but indicated more inattention, somatic complaints, and delinquent behaviors for the poor readers. School and health professionals should carefully assess youth with poor reading for behavioral and emotional symptoms and provide services when indicated.     

Delinquent peer affiliation and conduct problems: A twin study

Many putative environmental risks correlate with individuals' genotypes. The association between delinquent peer affiliation and conduct problems may occur because of shared genetic liability. Five hundred fifty three monozygotic and 558 dizygotic twin pairs, aged 11 to 18 years, were assessed for delinquent peer affiliation and conduct problems. The authors investigated whether genes contribute to both delinquent peer affiliation and the correlation between delinquent peer affiliations and conduct problems. Delinquent peer affiliation was influenced by genetic, shared environmental, and nonshared environmental factors; genetic factors also contributed to the correlation between delinquent peer affiliations and conduct problems, providing evidence for genotype-environment correlation. The magnitude of the genetic variance of conduct problems was contextually dependent on levels of delinquent peer affiliation and was greater at higher levels of delinquent peer affiliation.     

Longitudinal relations among perceived parental warmth,self-esteem and social behaviours from middle childhood to early adolescence in China: Disentangling between- and within-person associations

Although several studies have addressed the relations between perceived parental warmth and social behaviours, few have distinguished their between- and within-person effects or explored their within-person mediating mechanisms. This study examined the transactional relations among perceived parental warmth (i.e. maternal warmth and paternal warmth), children's self-esteem and children's positive/negative social behaviours (i.e. prosocial behaviour and delinquent behaviour) along with the mediating role of self-esteem after disentangling between- and within-person effects. A total of 4315 Chinese elementary children (44.9% girls; M_age = 9.93 years, SD = 0.73) completed relevant measures on four occasions employing 6-month intervals. Results of random-intercept cross-lagged panel models showed that (a) perceived parental warmth reciprocally and positively predicted prosocial behaviour and self-esteem; (b) perceived paternal warmth reciprocally and negatively predicted delinquent behaviour; (c) self-esteem reciprocally predicted prosocial and delinquent behaviour; (d) perceived maternal warmth reciprocally and positively predicted prosocial behaviour through self-esteem; (e) perceived parental warmth reciprocally and negatively predicted delinquent behaviour through self-esteem; and (f) perceived maternal and paternal warmth differed in their relations with prosocial and delinquent behaviours through self-esteem. These findings illuminated the complicated longitudinal within-person interactions among perceived parental warmth, self-esteem, and social behaviours, the specific mediating mechanism of self-esteem, and the differing results associated with perceived maternal and paternal warmth, all of which yield significant implications for assessments and early interventions aimed to promote positive social behaviour.     

Gender Differences in Risk and Promotive Classifications Associated With Adolescent Delinquency

How likely are children exposed to multiple risk factors to engage in delinquent behavior, to what extent do promotive factors mitigate exposure to these risk factors, and do the predictors of delinquent behavior differ by gender? To address these questions, the authors analyzed data from youths (229 boys, 187 girls) who completed the third wave of the Lehigh Longitudinal Study using Latent Profile Analysis. A unique risk and promotive class with slightly elevated rates of exposure to parental violence, mean levels of other risk factors and low levels of promotive factors was present for girls but not for boys. Additionally, for boys and girls, high-risk, low-promotive individuals were significantly more likely to engage in delinquent behavior than low-risk, high-promotive cases. Findings suggest the need to examine risk and promotive factors in combination to account for their shared influences on developmental outcomes for youth.
