Subtypes of adolescent offenders: affective traits and antisocial behavior patterns

Etiological models of life-course persistent offending often emphasize behavioral explanations. Suggestions that persistent offenders have psychopathy ignore the distinct non-behavioral features of the psychopathy disorder. Using a three-factor model of the PCL-YV and cluster analysis with 259 incarcerated adolescents, we identified four distinct juvenile subtypes on the basis of affective, interpersonal, and behavioral dimensions. Prospective and retrospective comparisons of antisocial behavior patterns found the cluster comprising all three psychopathy dimensions to be the most chronic and severe. Impulsive features alone were strongly associated with severe antisocial behaviors retrospectively, but not prospectively. Findings rebut the proposal that disruptive behavioral and impulsive symptoms can identify "fledgling psychopaths." Assessments that disregard callous-unemotional traits will likely result in high false positive rates among serious adolescent offenders. Implications for developmental models of chronic offending are discussed in light of the need for further follow-up into adulthood.     

Sex differences in the genetic and environmental influences on childhood conduct disorder and adult antisocial behavior

Sex differences in the genetic and environmental influences on childhood conduct disorder and adult antisocial behavior were examined in a large community sample of 6,383 adult male, female, and opposite-sex twins. Retrospective reports of childhood conduct disorder (prior to 18 years of age) were obtained when participants were approximately 30 years old, and lifetime reports of adult antisocial behavior (antisocial behavior after 17 years of age) were obtained 8 years later. Results revealed that either the genetic or the shared environmental factors influencing childhood conduct disorder differed for males and females (i.e., a qualitative sex difference), but by adulthood, these sex-specific influences on antisocial behavior were no longer apparent. Further, genetic and environmental influences accounted for proportionally the same amount of variance in antisocial behavior for males and females in childhood and adulthood (i.e., there were no quantitative sex differences). Additionally, the stability of antisocial behavior from childhood to adulthood was slightly greater for males than females. Though familial factors accounted for more of the stability of antisocial behavior for males than females, genetic factors accounted for the majority of the covariation between childhood conduct disorder and adult antisocial behavior for both sexes. The genetic influences on adult antisocial behavior overlapped completely with the genetic influences on childhood conduct disorder for both males and females. Implications for future twin and molecular genetic studies are discussed.     

成熟对青春期型反社会行为的影响

Moffitt的反社会行为发展理论将反社会行为分为两种类型, 即终身型和青春期型, 其中, 青春期型反社会行为在青少年群体中发生的频率更高, 它一般在青春期早期产生, 在青春期晚期或成年期早期结束, 青春期个体的发育成熟会对青春期型反社会行为产生影响。成熟包括生理成熟和心理成熟两方面, 生理成熟或心理成熟的单独影响和共同影响均从不同角度解释了青春期型反社会行为的产生、发展和停止：生理成熟对青春期型反社会行为具有发展和强化作用; 心理成熟对青春期型反社会行为具有减缓和削弱作用; 生理成熟与心理成熟的交互作用减弱或强化了青春期型反社会行为; 生理成熟与心理成熟之间的成熟差距抑制了青春期型反社会行为。未来的研究还需就拓展不同类型成熟的研究、改进成熟度的计算方法、结合青少年成熟特点进行有针对性干预等方面进行更多的尝试和探索。     

Trajectories of aggression, delinquency, and substance use across middle school among urban, minority adolescents

This study evaluated bidirectional associations between substance use, aggression, and delinquency across sixth, seventh, and eighth grades using data available from a large study of urban minority youth (n = 2,931). Group-based trajectory analysis revealed trajectories of aggression, delinquency, and substance use which support the existence of both adolescent-limited and life-course persistent offenders. In addition, a pattern of decreasing aggression was observed during middle school. Clear temporal associations were observed between developmental changes in aggression, delinquency, and substance use. Notably, the decreasing aggression trajectory was as likely to be associated with high trajectories of substance initiation as was the high aggression trajectory. Furthermore, trajectories of delinquency were differentially associated with future substance use; however, substance use trajectories did not predict trajectories of delinquency. There were few gender differences in the developmental progression of these problem behaviors during middle school with only two exceptions, males were more likely to follow a trajectory of decreasing aggression and a trajectory of high stable delinquency. Evaluations of ethnic/racial differences in the trajectory group membership also revealed few differences. The results of this study provide important information regarding interconnections between developmental changes in problem behavior that occur during the middle school years, highlighting groups that may be missed via traditional analytic approaches that predict mean changes.     

Self-concept and perception of early mother and father behavior in normal and antisocial adolescents

This study examines the self-concept and perceptions of early parental behavior in a group of 277 normal adolescents with respect to differences in age (12-18 years) and gender. A group of 30 antisocial adolescents of similar age (13-19 years) were included as a comparison group. The study was a cross-sectional questionnaire study and the Swedish translation of the Structural Analysis of Social Behavior (SASB) introject and mother/father questionnaires were used as measures of self- and parental concepts. Multivariate analyses of variance show that the normal adolescent self-concept and perception of early parental behavior are positive and that there are no age or gender differences. The early behavior of the mother is perceived more positively than that of the father. A positive self-concept is related to a positive perception of the parent's early behavior. The antisocial group of adolescents shows a more autonomous and negative self-concept and more negative perception of early parental behaviors. This was true especially in the group of antisocial girls. The conclusion from the study is that there is no evidence of a chaotic self-concept or tumultuous changes in the perceptions of early parental behavior during normal adolescence, but that an antisocial way of life might be reflected in a more negative and autonomous self-concept and in more negative perceptions of early parental behavior during adolescence.     

Social information processing and cardiac predictors of adolescent antisocial behavior

The relations among social information processing (SIP), cardiac activity, and antisocial behavior were investigated in adolescents over a 3-year period (from ages 16 to 18) in a community sample of 585 (48% female, 17% African American) participants. Antisocial behavior was assessed in all 3 years. Cardiac and SIP measures were collected between the first and second behavioral assessments. Cardiac measures assessed resting heart rate (RHR) and heart rate reactivity (HRR) as participants imagined themselves being victimized in hypothetical provocation situations portrayed via video vignettes. The findings were moderated by gender and supported a multiprocess model in which antisocial behavior is a function of trait-like low RHR (for male individuals only) and deviant SIP. In addition, deviant SIP mediated the effects of elevated HRR reactivity and elevated RHR on antisocial behavior (for male and female participants).     

Neuropsychological executive functioning in children at elevated risk for alcoholism: findings in early adolescence

One component of individual risk for alcoholism may involve cognitive vulnerabilities prodromal to alcoholism onset. This prospective study of 198 boys followed between 3 and 14 years of age evaluated neurocognitive functioning across three groups who varied in familial risk for future alcoholism. Measures of intelligence, reward-response, and a battery of neuropsychological executive and cognitive inhibitory measures were used. Executive functioning weaknesses were greater in families with alcoholism but no antisocial comorbidity. IQ and reward-response weaknesses were associated with familial antisocial alcoholism. Executive function effects were clearest for response inhibition, response speed, and symbol-digit modalities. Results suggest that executive deficits are not part of the highest risk, antisocial pathway to alcoholism but that some executive function weaknesses may contribute to a secondary risk pathway.     

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.     

Genetic influences on the overlap between low IQ and antisocial behavior in young children

The well-documented relation between the phenotypes of low IQ and childhood antisocial behavior could be explained by either common genetic influences or environmental influences. These competing explanations were examined through use of the Environmental Risk Longitudinal Twin Study 1994-1995 cohort (Moffitt & the E-Risk Study Team, 2002) of 1,116 twin pairs and their families. Children's IQ was assessed via individual testing at age 5 years. Mothers and teachers reported on children's antisocial behavior at ages 5 and 7 years. Low IQ was related to antisocial behavior at age 5 years and predicted relatively higher antisocial behavior scores at age 7 years when antisocial behavior at age 5 years was controlled. This association was significantly stronger among boys than among girls. Genetic influences common to both phenotypes explained 100% of the low IQ-antisocial behavior relation in boys. Findings suggest that specific candidate genes and neurobiological processes should be tested in relation to both phenotypes.     

Juvenile crime and juvenile justice: Patterns,models, and implications for clinical and legal practice

While rates of juvenile crime have declined over the past decade, public preoccupation with youth violence remains high, periodically fueling judicial and legislative “get-tough” policies and social movements. For most young people, criminal activity, if any, is mild, infrequent, peer-driven, and peaks in late adolescence and early adulthood, declining steadily thereafter. A small subset of persistently antisocial youths begin their criminal careers earlier, commit more frequent and more serious offenses, continue their offending throughout the life-course, and are characterized by a number of neurocognitive, personality, and diagnostic features. Individual, familial, and social forces all combine to influence juvenile criminal behavior, but another small subset of youths, with a characteristic cognitive and temperamental profile, appear to be staunchly resilient to the criminogenic influences around them. The success of intervention and treatment modalities for childhood antisocial behavior depends both on the type of subjects to which they are applied and the consistency and comprehensiveness with which they are implemented and carried out.     

Relations between self-serving cognitive distortions and overt vs. covert antisocial behavior in adolescents

The present study addressed the relations between cognitive distortions (inaccurate thoughts, attitudes, or beliefs) and antisocial behavior that is either overt/confrontational (e.g., fighting) or covert/nonconfrontational (e.g., stealing). A controlled analysis of 52 male delinquents and a comparison sample of 51 high school students aged 14–18 years found the delinquents to be higher in both cognitive distortions and self-reported antisocial behavior. Furthermore, cognitive distortion related specifically to overt and covert antisocial behavior in both samples. In particular, cognitive distortion having overt antisocial behavior as its referent (e.g., “People need to be roughed up once in a while”) evidenced a significant path to overt but not covert antisocial behavior. Conversely, covert-referential cognitive distortion (e.g, “If someone is careless enough to lose a wallet, they deserve to have it stolen”) evidenced a significant path to covert but not overt antisocial behavior. The theoretical and treatment implications of the findings are discussed. Aggr. Behav. 24:335–346, 1998. © 1998 Wiley-Liss, Inc.     

Psychosocial predictors of adult antisocial personality and adult convictions

In the Cambridge Study in Delinquent Development, 411 South London males have been followed up since age 8. This article investigates the ability of psychosocial risk factors measured at age 8 - 10 to predict antisocial personality measures at ages 18 and 32 and convictions between ages 21 and 40. The most important childhood predictors were a convicted parent, large family size, low intelligence or attainment, and child-rearing factors, including a young mother and a disrupted family. The accuracy of prediction of antisocial personality at age 32 on the basis of childhood risk factors measured more than 20 years before was surprising: nearly half of boys with a convicted parent at age 10 were antisocial at age 32, compared with one in six of the remainder. Over 60% of boys very high risk at age 8 - 10 became antisocial at age 32. While the present research shows how far adult antisocial and criminal behavior can be predicted in childhood, more research is needed to establish the precise causal mechanisms involved.     

Quantifying the psychopathic stare: Automated assessment of head motion is related to antisocial traits in forensic interviews

Clinicians have long noted that individuals with high psychopathic traits exhibit unique interpersonal style often observable during forensic interviews. Here we develop an automated approach for quantifying head dynamics during video-recorded naturalistic clinical interviews. We expected head dynamics would be related to psychopathic traits. As predicted, dwell times indicate that those with higher levels of psychopathic traits are characterized by more stationary head positions, focused directly towards the camera/interviewer, than were individuals low in psychopathic traits. These associations were primarily driven by developmental/antisocial features of psychopathy, indicating that those with severe and life-course persistent antisocial behavior exhibit more rigid and focused orienting of their head during interpersonal communication. These results encourage more research into the automated quantification of behavioral manifestations of personality to support clinical observations that psychopaths exhibit unique qualities in non-verbal interpersonal communication.     

Adolescent Self-Regulation as Resilience: Resistance to Antisocial Behavior within the Deviant Peer Context

This study tests the hypothesis that self-regulation serves as a resiliency factor in buffering youth from negative influences of peer deviance in middle to late adolescence. The interactive effects between peer deviance and self-regulation were investigated on change in antisocial behavior from age 17 to 19 years in an ethnically diverse sample of adolescents. A multi-agent construct was created using adolescent, parent, and teacher reports of self-regulation and peer deviance. Results indicated that self-regulation shows convergent validity and covaries as expected with developmental patterns of adolescent antisocial behavior. Self-regulation moderated the association of peer deviance with later self-reported adolescent antisocial behavior after controlling for prior levels of antisocial behavior. The implications of these findings for models for the development of antisocial behaviors and for intervention science are discussed.     

Juvenile Offending and Crime in Early Adulthood: A Large Sample Analysis

Using large sample archival data from the state of South Carolina’s juvenile justice agency and other state agencies, we examined the background, early experiential and delinquency-related variables predicting young adult (ages 17–30 years) offending among juvenile offenders. We also examined characteristics of juvenile offenders who committed only a single misdemeanor offense, compared to non-juvenile offenders. Finally, we examined the variables that accounted for group differences in persistence of juvenile offending. Early adverse experiences including family-related adversities, mental health problems, identification as having school-related disabilities and juvenile recidivism accounted for more than 20 % of the variance in adult offending. Cox proportional hazards analysis revealed several time-dependent covariates including gender, age at first offense and repeat versus one time offending. Contrary to the view that the one time, misdemeanor level juvenile offending represents only minor departure from normative adolescent behavior, we found that this group of offenders differed significantly from non-delinquents on every category of risk for adult offending and also were more likely than non-delinquents to commit felonies as adults. Finally, in comparing adolescence-limited offenders with life-course persistent offenders, we accounted for more than 50 % of the variance in criminal outcomes on the basis of measures of background, early adversity, psychological characteristics and age of first juvenile arrest or referral.     

Heterosexual risk behaviors in at-risk young men from early adolescence to young adulthood: prevalence,prediction, and association with STD contraction

Health-compromising lifestyles involve stable patterns of behavior and are associated with high-risk social environments and accelerated developmental trajectories. Developmentally, antisocial behavior is associated with such lifestyles. Mediational models predicting a measure of lifetime average sexual risk behavior assessed over a 10-year period (from ages 13-14 to 22-23 years) were examined for a sample of at-risk young men. The measure included years of abstinence from intercourse as well as levels of 3 key heterosexual indicators of risk: frequency of intercourse, number of intercourse partners, and condom use. Predictors included lifetime average measures of contextual, family, and peer process variables and individual behaviors. In addition, similar models for prediction of STD contraction were assessed. A younger age of onset of intercourse was associated with higher numbers of intercourse partners after onset. As hypothesized, findings indicated mediational associations of socioeconomic status, parental monitoring, deviant-peer association, antisocial behavior, and substance use in the prediction of sexual risk behavior. Lower condom use also predicted STD contraction.     

The Long-Term Neurocognitive Consequences of Prenatal Alcohol Exposure: A 14-Year Study

Prenatal alcohol exposure, at doses not generally associated with maternal alcohol problems, produces a broad array of neurocognitive deficits in offspring even in the absence of effects on growth and morphology. This report presents a summary of neurobehavioral, growth, and morphology findings from long-term follow-up of a birth cohort of 500 from apopulation-based study that has revealed attention, memory, and information processing deficits from birth through 14 years. Also observed (from school age through 14 years) have been problems with antisocial and delinquent behaviors, and classroom learning and behaviors; some of these problems may be secondary to earlier neurocognitive disabilities. Continuing research in behavioral and neurobehavioral teratology provides important opportunities for the neurosciences and for improved health of future generations.     

Motor impairment and antisocial behavior in adolescent males at high risk for schizophrenia

A familial link between schizophrenia and antisocial behavior has been established (e.g., Silverton, 1985). This study examined this relationship in a Danish cohort. The subjects were 36 high-risk males (offspring of a schizzophrenic parent) and 36 low-risk males (offspring of parents without psychopathology). This high-risk subjects exhibited more antisocial behavior than the low-risk subjects. We tested the hypothesis of a correlation between neurointegrative deficits, as defined by motor impairment, and antisocial behavior, rated at ages 10–13, in subjects at genetic risk for schizophrenia. Path analyses were conducted from motor impairment at 1 year and motor impairment at 10–13 years to antisocial behavior separately for high-risk and low-risk subjects. Adolescent motor impairment was a significant predictor of antisocial behavior for high-risk subjects. Motor impairment at 1 year was also associated with antisocial behavior for these subjects, although the association was partly due to the indirect effects of motor impairment at 1 year on motor impairment at 10–13 years, which, in turn, was associated with changes in antisocial behavior. As predicted, none of the path coefficients nor the effect coefficient was significant for low-risk subjects.     

Developmental Precursors of Moral Disengagement and the Role of Moral Disengagement in the Development of Antisocial Behavior

The purpose of the study was to advance our understanding of the developmental precursors of Moral Disengagement (MD) and the role of MD in the development of antisocial behavior from early risk among an ethnically diverse sample of 187 low-income boys followed prospectively from ages 1.5 to 17. Results indicated associations between early rejecting parenting, neighborhood impoverishment, and child empathy and later MD. The link between some of these early constructs and later antisocial behavior was mediated by MD. Finally, in an exploratory path model both MD and biases in social information processing were found to mediate separate paths from early risk factors to later antisocial behavior. Results were partially consistent with the notion that adolescent MD was predicted by a combination of early family, neighborhood, and child risk factors, and that MD may be a mechanism underlying some boys’ risk of antisocial behavior.     

Elevated trajectories of externalizing problems are associated with lower awakening cortisol levels in midadolescence

A growing body of research suggesting a negative association between basal levels of cortisol and persistent antisocial behavior has emerged. The present study examined relations between awakening cortisol levels and antisocial trajectories from ages 5 to 15 years among individuals in the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development. Antisocial behavior was defined by semiparametric group modeling techniques, which revealed antisocial patterns parallel to Moffitt's (1993) taxonomy of antisocial trajectories. In contrast to the claim that biological diatheses are uniquely characteristic of individuals who demonstrate an early-onset pattern of antisocial behavior, our results suggest that individuals with elevated patterns of antisocial behavior between 5 and 15 years of age-irrespective of the timing of onset or desistance-are more likely to evidence lower awakening cortisol levels compared with individuals with persistently low levels of antisocial behavior.
