Childhood predictors of desistance and level of persistence in offending in early onset offenders.

Childhood predictors of adolescent offending careers were studied in 310 boys from the longitudinal Pittsburgh Youth Study who started offending prior to age 12. Three main groups were distinguished: serious persisters (n = 95), moderately serious persisters (n = 117), desisters (n = 63), and an intermittent group (n = 35). Group membership was predicted using risk and promotive factors measured in childhood. Serious and moderately serious persisters could be distinguished well from desisters (29.2% and 32.3% explained variance). Distinction between the two persister groups proved somewhat more difficult (20.9% explained variance). More serious persisters than desisters showed disruptive behavior, while moderately serious persisters fell in between. Further, more moderately serious persisters were marked by social disadvantage. Family involvement, small family and positive peer relationships were promotive of desistance. Concluding, early onset offenders show considerable heterogeneity in their adolescent offending careers which seem to some extent to be predicted by different sets of risk and promotive factors.

What predicts adolescent violence in better-off neighborhoods?

Predictors of repeated violent delinquency across ages 13-19 were investigated in a longitudinal sample of 420 urban adolescent males living in high- compared to low-socioeconomic status (SES) neighborhoods. Adolescents in high-SES neighborhoods were significantly less likely than their counterparts in low-SES neighborhoods to engage in serious and violent delinquency. Results indicated that risk factors for later repeated violence among adolescents in high-SES neighborhoods, such as physical aggression, may be biologically based, whereas risk factors for later violence among adolescents in low-SES neighborhoods, such as poor parent-adolescent communication and early intercourse, appeared to be context-dependent. Having positive attitudes toward problem behavior and delinquent peers increased risk for later violence regardless of neighborhood SES type. Theoretical and practical implications of the findings are discussed.

The concentration of offenders in families, and family criminality in the prediction of boys' delinquency.

The main aims of this study were to investigate inter-relationships among offending by three generations of relatives (fathers, mothers, sons, daughters, uncles, aunts, grandfathers and grandmothers) and the concentration of offending in families. This study also investigates how far criminal relatives predict a boy's delinquency. The parents of 1395 Pittsburgh boys aged 8, 11 or 14 reported arrests by all relatives. Parent reports of boys' arrests predicted their later referrals to juvenile court, demonstrating predictive validity. Offenders were highly concentrated in families; if one relative had been arrested, there was a high likelihood that another relative had also been arrested. Arrests of relatives were compared with arrests of the boy, court petitions of the boy, and the boy's reported delinquency (according to the parent, boy and teacher). Arrests of brothers, sisters, fathers, mothers, uncles, aunts, grandfathers and grandmothers all predicted the boy's delinquency. The most important relative was the father; arrests of the father predicted the boy's delinquency independently of all other arrested relatives. Studies of explanatory variables suggested that having a young mother, living in a bad neighbourhood, and low guilt of the boy may be links in the causal chain between arrested fathers and delinquent boys.

Psychopathology as a predictor of adolescent drug use trajectories.

The authors examined early psychopathology as a predictor of trajectories of drug use from ages 13-18 years. Six years of annual data were analyzed for 506 boys using a mixed effects polynomial growth curve model. They tested whether distinct measures of psychopathology and behavioral problems (i.e., attention-deficit/hyperactivity disorder, oppositional defiant disorder, conduct disorder, depression, and violence) assessed in early adolescence could prospectively predict level and change in alcohol and marijuana use. Higher levels of all of the types of psychopathology predicted higher levels of alcohol use, and higher levels of attention-deficit/hyperactivity disorder, conduct disorder, and violence predicted higher levels of marijuana use. Only conduct disorder predicted linear growth in alcohol use, and none of the measures predicted growth in marijuana use. The results suggest that drug use prevention programs should target youths with early symptoms of psychopathology.

Maltreatment of boys and the development of disruptive and delinquent behavior.

Data from a longitudinal, inner-city community sample were used to examine the prevalence of child maltreatment in males and to relate this to disruptive and delinquent child behavior. By age 18 years, almost one fourth of the families had been referred to Children and Youth Services (CYS). Investigation by the CYS resulted in substantiated maltreatment of 10% of the participants, mostly for physical abuse and neglect. Almost all maltreatment was perpetrated by people living in the same house as the victim. Maltreatment was related to the boys progressing on three pathways in disruptive and delinquent behavior: authority conflict pathway, overt pathway, and covert pathway. Two thirds of the victims showed authority conflict problems, and almost all of the maltreated boys displayed behaviors characteristic of the overt and covert pathways. Victims, compared to matched controls, were more likely to have engaged in behaviors characteristic of the authority conflict and the overt pathways but less strongly engaged in behaviors associated with the covert pathway. Victims were also more likely than controls to have a referral to juvenile court. Most of the CYS contact tended to precede or co-occur with onset of overt and covert problem behavior, but about half of the onset of authority conflict behaviors tended to precede contact with CYS.

Male mental health problems, psychopathy, and personality traits: key findings from the first 14 years of the Pittsburgh Youth Study.

This paper reviews key findings on juvenile mental health problems in boys, psychopathy, and personality traits, obtained in the first 14 years of studies using data from the Pittsburgh Youth Study. This is a study of 3 samples, each of about 500 boys initially randomly drawn from boys in the 1st, 4th, and 7th grades of public schools in Pittsburgh. The boys have been followed regularly, initially each half year, and later at yearly intervals. Currently, the oldest boys are about 25 years old, whereas the youngest boys are about 19. Findings are presented on the prevalence and interrelation of disruptive behaviors, ADHD, and depressed mood. Results concerning risk factors for these outcomes are reviewed. Psychological factors such as psychopathy, impulsivity, and personality are described. The paper closes with findings on service delivery of boys with mental health problems.

A new measure of parenting practices involving preadolescent- and adolescent-aged children.

Parenting behaviors have played critical roles in various theoretical and clinical models that have sought to explain the development and course of deviant child behavior. Notwithstanding the importance of this topic, the extant literature reveals very few adequate instruments for describing such patterns. To address 3 this need, the authors developed a self-report procedure for assessing parenting practices involving preadolescent and adolescent children, the Loeber Youth Questionnaire. Preliminary reliability and concurrent validity data were quite encouraging, and the instrument's two major dimensions (affect and control) fit well with the existing clinical and research literature. Limitations and future research directions are addressed.

Patterns and correlates of agreement between parent, teacher, and male adolescent ratings of externalizing and internalizing problems.

The authors examined how well 394 triads of male youths, caregivers, and teachers agreed about youth problems reported on the Achenbach checklists. Dyadic agreement was measured through difference scores (subtracting the raw score of youth self-report from the caregiver's or teacher's score for shared items), q correlations between pairs of raters across items, and D2 (generalized distance between item profiles) for both externalizing and internalizing items. Teachers reported fewer internalizing and externalizing problems than did caregivers or youths. Teacher-youth disagreement was higher for African American than European American males about externalizing criteria. Caregiver depression and stress (but not paternal antisocial behavior or maternal substance abuse) correlated with higher disagreement with other informants about all criteria. These factors appear to increase disagreement about the level of problems but not about specific symptom patterns.

Boys who join gangs: a prospective study of predictors of first gang entry.

In a representative sample of boys who were in the 7th grade of an urban public school system at the start of a 6-year longitudinal study, more African American boys (23.8%) than non-Hispanic White boys (3.9%) had entered an antisocial gang by age 19. There were too few White gang members to study, but among African American boys, first gang entry was predicted prospectively by both baseline conduct disorder (CD) behaviors and increasing levels of CD behaviors prior to gang entry. This suggests that gang entry may be a further developmental step for some boys who are already on a trajectory of worsening antisocial behavior. Having friends prior to gang entry who engaged in aggressive delinquency increased the risk of gang entry further, but only during early adolescence. Family income and parental supervision also independently predicted gang entry, but the direction of their influences depended on the youth's age.

Developmental aspects of delinquency and internalizing problems and their association with persistent juvenile substance use between ages 7 and 18.

Analyzed longitudinal data from 3 samples of the Pittsburgh Youth Study on boys ages 7 to 18 to examine the co-occurrence of persistent substance use with other problem behaviors, including attention deficit hyperactivity disorder (ADHD), persistent delinquency, and persistent internalizing problems (i.e., depressed mood, anxiety, shy or withdrawn behavior). In preadolescence, persistent substance users also tended to be persistent delinquents, and half of this group displayed persistent internalizing problems as well. In adolescence, a third of the persistent substance users did not manifest other persistent problems. Across the samples, the least common substance users were those who manifested persistent internalizing problems only. Logistic regression analyses showed that persistent substance use in preadolescence was predicted by persistent delinquency and internalizing problems and in adolescence by persistent delinquency only. The combination of persistent substance use and delinquency was predicted by oppositional defiant disorder in middle childhood and by persistent internalizing problems in middle to late childhood. ADHD was not a predictor of persistent substance use (and delinquency) in any of the analyses. Results are discussed in terms of developmental models of multiproblem youth with an eye on improving early interventions.

Gun injury and mortality: the delinquent backgrounds of juvenile victims.

Serious injuries and deaths of three samples of boys were examined in an inner-city, longitudinal study. By age 19, almost 1 in 10 of the 506 participants in the oldest sample had been seriously wounded or killed. Two thirds of this group had been either wounded or killed by guns. Victims, compared to controls, tended to have a history of engaging in serious delinquency, gang fights, and selling drugs. They also tended to carry guns. The delinquent lifestyle of the victims was also evident from their court records. Victims tended to do poorly academically in school, received poorer parental supervision, had poorer communication with their parents, and had a long history of behavior problems.

Developmental associations between substance use and violence.

This study examined the developmental associations between substance use and violence. We examined the trends in each behavior throughout adolescence, how the behaviors covaried over time, and the symmetry of associations taking into account frequency and severity of each behavior. We also examined whether changes in one behavior affected changes in the other behavior over time. Six years of annual data were analyzed for 506 boys who were in the seventh grade at the first assessment. Concurrent associations between frequency of substance use and violence were relatively strong throughout adolescence and were somewhat stronger for marijuana than alcohol, especially in early adolescence. Type or severity of violence was not related to concurrent alcohol or marijuana frequency, but severity of drug use was related to concurrent violence frequency. Depending, to some degree, on the age of the subjects, the longitudinal relationships between substance use and violence were reciprocal during adolescence and slightly stronger for alcohol and violence than for marijuana and violence. Further, increases in alcohol use were related to increases in violence: however, when early alcohol use was controlled, increases in marijuana use were not related to increases in violence. Only in early adolescence was the longitudinal relationship between marijuana use and later violence especially strong. The strength of the longitudinal associations between violence and substance use did not change when common risk factors for violence and substance use were controlled. Overall, the data lend more support for a reciprocal than for a unidirectional association between substance use and violence. Prevention efforts should be directed at aggressive males who are multiple-substance users in early adolescence.

Development of juvenile aggression and violence. Some common misconceptions and controversies.

This article addresses 5 misconceptions and controversies concerning the development of aggression and violence: (a) the misconception that high stability coefficients of aggression over time imply that discontinuity of aggression from childhood to early adulthood is negligible; (b) the misconception that all serious forms of violence have an origin in aggression during early childhood; (c) the controversy about whether a single pathway or multiple pathways best represent individuals' development of antisocial behavior, including violence; (d) the controversy about whether causes of violence are similar to the causes of property offending; and (e) the assumption that the development of violence in women is very similar to that in men. Each of the points is discussed against empirical findings. Theoretical, research, and applied implications of the 5 points are discussed.

The precursors of young fatherhood and its effect on delinquency of teenage males.

PURPOSE: To investigate the relationship of young fatherhood to delinquency, in terms of precursors and impact of becoming a father on delinquency. METHODS: The sample consisted of 506 inner-city adolescent males from public schools who were part of a longitudinal study. The independent variables included participants' behaviors, attitudes, demographics, family, peers, and school performance. Young fathers were defined as having become fathers before age 19 years. Two measures of delinquency were used. Odds ratios were calculated, followed by two stepwise logistic regressions. For comparison with matched controls, fathers (n = 62) were matched with nonfathers on age, race, and neighborhood. RESULTS: The prevalence of young fatherhood was 12.3%. Fathers were more than twice as likely to be delinquent than nonfathers. The factors related to young fatherhood were a subset of those for delinquency. In the stepwise logistic regressions, several factors were uniquely related to either delinquency or young fatherhood. Delinquency did not decrease after becoming a father. Young fathers tended to commit more covert-type delinquent acts than their controls. CONCLUSIONS: The results indicate that a single theory of problem behavior cannot adequately account for the association between young fatherhood and delinquency.

Delay of gratification, psychopathology, and personality: is low self-control specific to externalizing problems?

We assessed the delay of gratification behavior of 428 twelve- and thirteen-year-old boys, half of whom were known to manifest symptoms of behavioral disturbance. Consistent with the hypothesis that low self-control is a risk factor specific to externalizing (aggressive and delinquent) disorders, boys who showed signs of externalizing disorders tended to seek immediate gratification in a laboratory task more often than both nondisordered boys and boys who showed signs of internalizing (anxious and depressed) disorders. In addition, children who were able to delay immediate gratification were described by their mothers as ego controlled, ego resilient, conscientious, open to experience, and agreeable. These results suggest that poor delay of gratification may be one of a select number of specific risk factors for externalizing disorder, and that good delay of gratification is linked to multiple adaptive tendencies in early adolescence.

Resilient, overcontrolled, and undercontrolled boys: three replicable personality types.

Three replicable personality types were identified in a sample of 300 adolescent boys and shown to generalize across African Americans and Caucasians. The types had conceptually coherent relations with the Big Five dimensions, ego resiliency, and ego control, and converged with three of the types identified by J. Block (1971). The behavioral implications of the types were explored using several independent data sources. Resilients were intelligent, successful in school, unlikely to be delinquents, and relatively free of psychopathology; Overcontrollers shared some of these characteristics but were also prone to internalizing problems; and Undercontrollers showed a general pattern of academic, behavioral, and emotional problems. This research demonstrates that replicable and generalizable personality types can be identified empirically, and that the unique constellation of traits defining an individual has important consequences for a wide range of outcomes.

Facial expressions of emotion and psychopathology in adolescent boys.

On the basis of the widespread belief that emotions underpin psychological adjustment, the authors tested 3 predicted relations between externalizing problems and anger, internalizing problems and fear and sadness, and the absence of externalizing problems and social-moral emotion (embarrassment). Seventy adolescent boys were classified into 1 of 4 comparison groups on the basis of teacher reports using a behavior problem checklist: internalizers, externalizers, mixed (both internalizers and externalizers), and nondisordered boys. The authors coded the facial expressions of emotion shown by the boys during a structured social interaction. Results supported the 3 hypotheses: (a) Externalizing adolescents showed increased facial expressions of anger, (b) on 1 measure internalizing adolescents showed increased facial expressions of fear, and (c) the absence of externalizing problems (or nondisordered classification) was related to increased displays of embarrassment. Discussion focused on the relations of these findings to hypotheses concerning the role of impulse control in antisocial behavior.

Measuring impulsivity and examining its relationship to delinquency.

A multimethod, multisource assessment of impulsivity was conducted in a sample of more than 400 boys who were members of a longitudinal study of the development of antisocial behavior. Exploratory and confirmatory factor analysis of the 11 different impulsivity measures revealed two impulsivity factors: Cognitive and Behavioral. Cognitive and behavioral impulsivity had similar correlations with socioeconomic status. Cognitive impulsivity was more strongly related to IQ than was behavioral impulsivity. Behavioral impulsivity was more strongly related to delinquency at ages 10 and 12-13 than was cognitive impulsivity. Consistent with theoretical prediction, our results also indicate that behavioral impulsivity was especially related to serious delinquency that is stable over time.

The "little five": exploring the nomological network of the five-factor model of personality in adolescent boys.

The California Child Q-set (CCQ) was used to explore the structure of personality in early adolescence and to develop scales to measure the "Big Five" dimensions: Extraversion, Agreeableness, Conscientiousness, Neuroticism, and Openness to Experience. Mothers provided Q-sorts of 350 ethnically diverse boys between 12 and 13 years old. Analyses of the construct validity of the scales provided a nomological network relating the Big Five to theoretically and socially important criterion variables, such as juvenile delinquency, Externalizing and Internalizing disorders of childhood psychopathology, school performance, IQ, SES, and race. These effects were obtained using diverse methods, including self-reports from the boys, ratings by their mothers and their teachers, and objective-test data. In addition to the Big Five, analyses also suggested 2 possibly age-specific dimensions of personality in early adolescence. Discussion is focused on the changing manifestations of personality traits throughout development.

Explaining the relation between IQ and delinquency: class, race, test motivation, school failure, or self-control?

An inverse relation between IQ and delinquency has been well established, but the direction of effect remains to be specified. Differing explanatory accounts of the relation were empirically examined in the present study using data on 13-year-old boys involved in a high-risk longitudinal study. Accounts that interpreted the relation as spurious or that posited that delinquency-related factors lead to low IQ scores received no support; findings were most consistent with the hypothesis that the direction of effect runs from low IQ to delinquency. The IQ-delinquency relation was robust after race, class, and observed test motivation were controlled statistically. Additionally, the effect of IQ was mediated by school performance for Black youth but not for White youth.
