Synergistic interaction of child manageability problems and parent-discipline tactics in predicting future growth in externalizing behavior for boys.

Manageability problems during early childhood for boys were hypothesized to disrupt parental discipline practices. In turn, disrupted parental discipline practices were hypothesized to interact with manageability problems during late childhood to predict change in antisocial behavior during the transition from elementary to middle school. Results indicated that maternal retrospective perceptions of unmanageability predicted observed maternal discipline practices, even when maternal antisocial behavior and depressed mood and the disruptive and antisocial behavior of the boy were statistically controlled. Graphical analyses and latent class growth models indicated that level of temper tantrums interacted with maternal discipline in predicting change in teacher ratings of antisocial behavior. The nature of the interaction indicated that maternal discipline was a risk factor for growth in antisocial behavior only for boys with high levels of tantrums.

Pursuing the psychopath: Capturing the fledgling psychopath in a nomological net.

The present article reports on an attempt to import the concept of psychopathy at the childhood level. Childhood psychopathy was assessed in 430 boys ages 12 and 13 years by using caretaker reports on a translation of an adult psychopathy assessment instrument. A systematic construct validation approach revealed that childhood psychopathy fits into the nomological network surrounding adult psychopathy. Children with psychopathic personalities, like their adult counterparts, were serious and stable offenders, impulsive, and more prone to externalizing than internalizing disorders. Childhood psychopathy also provided incremental validity in predicting serious stable antisocial behavior in adolescence over and above other known predictors and one other classification approach. These results suggest that psychopathy has a childhood manifestation that can be measured reliably. Implications and future directions are outlined.

Assessing psychopathic attributes in a noninstitutionalized population.

Examined antisocial dispositions in 487 university students. Primary and secondary psychopathy scales were developed to assess a protopsychopathic interpersonal philosophy. An antisocial action scale also was developed for purposes of validation. The primary, secondary, and antisocial action scales were correlated with each other and with boredom susceptibility and disinhibition but not with experience seeking and thrill and adventure seeking. Secondary psychopathy was associated with trait anxiety. Multiple regression analysis revealed that the strongest predictors of antisocial action were disinhibition, primary psychopathy, secondary psychopathy, and sex, whereas thrill and adventure seeking was a negative predictor. This argues against a singular behavioral inhibition system mediating both antisocial and risk-taking behavior. These findings are also consistent with the view that psychopathy is a continuous dimension. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Skin conductance level reactivity moderates the association between harsh parenting and growth in child externalizing behavior.

Skin conductance level reactivity (SCLR) was examined as a moderator of the association between harsh parenting at age 8 years and growth in child externalizing behavior from age 8 to age 10 (N = 251). Mothers and fathers provided reports of harsh parenting and their children's externalizing behavior; children also provided reports of harsh parenting. SCLR was assessed in response to a socioemotional stress task and a problem-solving challenge task. Latent growth modeling revealed that boys with higher harsh parenting in conjunction with lower SCLR exhibited relatively high and stable levels of externalizing behavior during late childhood. Boys with higher harsh parenting and higher SCLR exhibited relatively low to moderate levels of externalizing behavior at age 8, but some results suggested that their externalizing behavior increased over time, approaching the same levels as boys with higher harsh parenting and lower SCLR by age 10. For the most part, girls and boys with lower harsh parenting were given relatively low and stable ratings of externalizing behavior throughout late childhood. Results are discussed from a developmental psychopathology perspective with reference to models of antisocial behavior in childhood. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Suicidal ideation and its recurrence in boys and men from early adolescence to early adulthood: An event history analysis.

Occurrence and recurrences of suicidal ideation (SI) were modeled among boys/men assessed annually from ages 12 to 29 years. Multiple-spell discrete-time event-history analyses permitted (a) determination of whether risk for SI escalates with prior experiences of SI (spell effects), while (b) accounting for changes in risk with time (period effects) and (c) controlling for vulnerability factors. Self-reported SI (presence/absence in past week), depressive symptoms, alcohol/substance use, antisocial behavior, and official arrest records were collected annually from 205 boys recruited on the basis of community risk for delinquency. Parents' self-reported psychopathology and SES were collected in childhood. Period effects supported decreasing risk for SI over time. Spell and time-varying 1-year lagged substance use and depressive symptoms independently predicted increased risk for SI. Models involving SI with intent were explored. Consistent with interpersonal psychological theory, risk for young men's SI increases with past experience of SI, even with key propensities controlled. However, risk also decays over time. Targeting conditions that confer risk for SI is essential. Preventing and delaying SI occurrence and recurrence may represent independent mechanisms by which prevention efforts operate.

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. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sibling relationships as contexts for delinquency training in low-income families.

The purpose of the study was to investigate the link between sibling relationships and antisocial behavior in 208 boys from low-income families. Sibling relational attributes and mother-target child (MTC) relationship quality were assessed when the target child (TC) was 10 years old. At ages 11 and 12, TC antisocial behavior and TC reports of peer antisocial behavior were evaluated. Results indicated that MTC negative relationship quality was significantly related to sibling conflict. In turn, sibling conflict was a significant predictor of antisocial behavior; sibling warmth/closeness was related to TC reports of peer antisocial behavior. Findings also indicated that sibling relationship quality was related to antisocial behavior after controlling for MTC negativity. Implications for interventions are discussed.

Adolescence-limited and life-course-persistent antisocial behavior: a developmental taxonomy

A dual taxonomy is presented to reconcile 2 incongruous facts about antisocial behavior: (a) It shows impressive continuity over age, but (b) its prevalence changes dramatically over age, increasing almost 10-fold temporarily during adolescence. This article suggests that delinquency conceals 2 distinct categories of individuals, each with a unique natural history and etiology: A small group engages in antisocial behavior of 1 sort or another at every life stage, whereas a larger group is antisocial only during adolescence. According to the theory of life-course-persistent antisocial behavior, children's neuropsychological problems interact cumulatively with their criminogenic environments across development, culminating in a pathological personality. According to the theory of adolescence-limited antisocial behavior, a contemporary maturity gap encourages teens to mimic antisocial behavior in ways that are normative and adjustive.     

The relationship of attention deficit hyperactivity disorder and conduct disorder to juvenile delinquency: legal implications

Attention deficit/hyperactivity disorder (ADHD) and conduct disorder (CD) are both disorders of childhood and adolescence that all too frequently extend into adulthood. But just what is the relationship between these two disorders? This study explores the overlap between these two disorders as they relate to juvenile delinquency; both are significant risk factors for the development of antisocial behavior. But there is more significance to the presence or absence of ADHD or CD in later antisocial behavior. Higher levels of defiant and/or aggressive behavior lead to antisocial acts as compared with lower levels of defiance and antisocial acts. Boys diagnosed with ADHD have higher felony rates than normal control boys, yet ADHD is not nearly as strong a predictor of offending behavior as is CD in study subjects. The presence of both CD and ADHD contributes to illegal behavior, and it is likely that early intervention in both disorders will reduce the prevalence of 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 (mean age 10.2 yrs at screening) 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 2 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 yrs and 12–23 yrs than was cognitive impulsivity. Consistent with theoretical prediction, results also indicate that behavioral impulsivity was especially related to serious delinquency that is stable over time.

A comparison of girls' and boys' aggressive-disruptive behavior trajectories across elementary school: Prediction to young adult antisocial outcomes.

Multiple group analysis and general growth mixture modeling was used to determine whether aggressive- disruptive behavior trajectories during elementary school, and their association with young adulthood antisocial outcomes, vary by gender. Participants were assessed longitudinally beginning at age 6 as part of an evaluation of 2 school-based preventive programs. Two analogous trajectories were found for girls and boys: chronic high aggression- disruption (CHAD) and stable low aggression- disruption (LAD). A 3rd class of low moderate aggression- disruption (LMAD) for girls and increasing aggression- disruption (IAD) for boys also was found. Girls and boys in analogous CHAD classes did not differ in trajectory level and course, but girls in the CHAD and LAD classes had lower rates of antisocial outcomes than boys. Girls with the LMAD trajectory differed from boys with the IAD trajectory. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A performance model for academic achievement in early adolescent boys.

Tests a model for conduct-related school failure in young adolescent boys. In this model, family characteristics and child antisocial behavior serve as predictors of school adjustment and academic performance. Ss were 206 youths and their families, followed from the 4th through 8th grades. Results indicated that low parental academic achievement was associated with ineffective discipline practices and child antisocial behavior in the 6th grade. Ineffective discipline had a direct and negative effect on boys' 7th-grade academic engagement. Boys' academic engagement, in turn, had a direct and positive effect on 8th grade academic achievement. A smaller direct effect of parental achievement on child achievement was also found. Results are discussed in terms of research on parental influence on academic success and life span models of the development of antisocial behavior.

The persistence of teacher-reported behavioral problems among children aged 8 to 12

This investigation assessed psychiatric symptoms in children reported by teachers at two points of time, and the persistence of symptom groups over an interval of four years. 1128 children born in 1981 (mean age 8.5 yr in Study 1 and 12.5 yr in Study 2) were studied, using the Rutter Scale B2 questionnaires in both studies. The frequencies of teacher-reported problems generally decreased over an interval of four years. Hyperkinetic symptoms were the most prevalent at both occasions. Gender differences were seen in both studies, boys outnumbering girls on most items. Symptoms were classified into five groups representing hyperactivity, internalizing and externalizing behaviour, relationship difficulties, and habits. The correlations of these different groups in Study 1 with those in Study 2 were moderate. Among deviant girls, correlations were high or moderate for externalizing, hyperactivity and internalizing behavior between the two studies. For deviant boys, high correlations between the studies were found for hyperactivity and habits. Externalizing behavior was also highly correlated with relationship difficulties among deviant boys. Two symptom groups (hyperactivity and relationship difficulties) and low performance level in Study 1 increased the probability of being deviant in Study 2 among boys, and four interactional terms (hyperactivity by relationship difficulties, hyperactivity by performance level, internalizing by performance level, and externalizing by relationship difficulties) also had an effect. Among girls, the probability of being deviant in Study 2 was increased if they were hyperactive or had relationship difficulties in Study 1. Furthermore, one interactional term (hyperactivity by performance level) had an impact on deviance among girls.     

Personal values as a mediator between parent and peer expectations and adolescent behaviors.

The current study examined the mediating role of adolescents' personal values on the relation between maternal and peer expectations for prosocial behaviors and adolescents' self-reported prosocial and antisocial behaviors. One hundred thirty-four adolescents (mean age = 16.22 years, 54% girls) completed measures of their own values and behaviors, as well as their perceptions of the positive expectations that their mother and their best friend(s) had for their (the adolescents') prosocial behaviors. Stepwise regression analyses suggested that adolescents' personal prosocial values mediated the relation between adolescents' perceptions of both maternal and peer expectations and adolescents' prosocial behaviors. In addition, for boys, perceptions of positive peer expectations were directly and negatively related to antisocial behaviors. The current study has important implications for parents, educators, and practitioners who are concerned about promoting adolescents' positive behaviors and discouraging negative behaviors.

Right anterior cingulate: A neuroanatomical correlate of aggression and defiance in boys.

Variation in emotional processes may contribute to aggressive and defiant behavior. This study assessed these problem behaviors in a large sample of children and adolescents in relation to the volume of two cortical regions with prominent roles in emotion processing, the anterior cingulate cortex (ACC) and ventromedial prefrontal cortex (vmPFC). One hundred seventeen participants (61 boys, 56 girls), ages 7-17, were recruited from the community. Aggressive and defiant behavior was measured using the parent- and teacher-reported Pediatric Behavior Scale and volumetric measures were generated using structural MRI. Regression analyses indicated a significant sex X ACC volume interaction in predicting aggressive and defiant behavior, without significant results for the vmPFC. Follow-up analyses showed that aggressive and defiant behavior is associated with decreased right ACC volume in boys and a nonsignificant reduction in left ACC volume in girls. These results are consistent with the notion that the right ACC acts as a neuroanatomical correlate of aggression and defiance in boys. The authors discuss this finding in light of its implications for understanding the neural correlates of antisocial behavior. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Parenting, peers, and the stability of antisocial behavior in preadolescent boys.

This study examined the linkages between parental discipline practices, peer relationships, and antisocial behavior in a 2-yr longitudinal study (N?=?206) of preadolescent boys (aged 9–10 yrs at 1st assessment). Structural equation models were used to estimate the stability of parenting, peer relations, and antisocial constructs, and their effects on each other. The results showed that preadolescent antisocial behavior had substantial concurrent negative effects on the quality of parental discipline and peer relationships. Evidence for a reciprocal relationship between parental discipline and child antisocial behavior was found. The study specifies how parental discipline practices are involved in maintaining the stability of antisocial behavior in preadolescents. Low popularity with peers did not directly influence the child's antisocial behavior. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An investigation of systematic changes in occupational exposure

Nonstationary behavior in occupational exposure was examined among a number of job groups from different industries. A change in the mean level of exposure between two survey periods was evaluated by applying mixed-effects models. Overall, differences between surveys were observed in slightly more than one-third of the industries analyzed and in about one-quarter of the total number of comparisons performed. Exposures in the majority of cases decreased in the later survey. Further analyses examined the impact of nonstationary exposures on the estimation of the between- and within-worker components of variance. When changes in the mean exposure level were detected, point estimates of the variance components generated under the mixed model were compared with those estimates obtained under the one-way random-effects model, which assumes that the mean exposure level remains constant over time. The results indicate that the magnitude of the bias in the variance component estimates can be substantial when the misspecified model is applied. It is concluded that, in the absence of changes known to affect exposure, data collected within a year are likely to result in relatively valid inferences about mean and variance parameters using models that assume stationarity; for periods extending beyond a year, systematic changes in exposure are more likely to occur. Thus, exposure assessment strategies should be designed so that sufficient data are collected among groups of workers to investigate systematic changes and to ensure that appropriate statistical models are applied. In this way, occupational hygienists will be able to make reliable inferences about the underlying distribution of exposures pertinent to each occupational group.     

Assessment of psychopathy as a function of age.

The assessment of psychopathy was examined as a function of age in 889 male prison inmates between the ages of 16 and 69. Ratings of psychopathy were made with the Psychopathy Checklist (PCL), which measures 2 correlated factors. Factor 1 describes a cluster of affective-interpersonal traits central to psychopathy. Factor 2 describes traits and behaviors associated with an unstable, unsocialized lifestyle, or social deviance. Cross-sectional analyses revealed that mean scores on Factor 1 were stable across the age-span; mean scores on Factor 2 declined with age. The prevalence of antisocial personality disorder, and, to a lesser extent of PCL-defined psychopathy, also declined with age. The results are consistent with a conceptualization of psychopathy as encompassing 2 correlated but distinct constructs. They also suggest that age-related differences in traits related to impulsivity, social deviance, and antisocial behavior are not necessarily paralleled by differences in the egocentric, manipulative, and callous traits fundamental to psychopathy.

Modeling Growth in Boys' Aggressive Behavior Across Elementary School: Links to Later Criminal Involvement, Conduct Disorder, and Antisocial Personality Disorder.

The present study used general growth mixture modeling to identify pathways of antisocial behavior development within an epidemiological sample of urban, primarily African American boys. Teacher-rated aggression, measured longitudinally from 1st to 7th grade, was used to define growth trajectories. Three high-risk trajectories (chronic high, moderate, and increasing aggression) and one low-risk trajectory (stable low aggression) were found. Boys with chronic high and increasing trajectories were at increased risk for conduct disorder, juvenile and adult arrest, and antisocial personality disorder. Concentration problems were highest among boys with a chronic high trajectory and also differentiated boys with increasing aggression from boys with stable low aggression. Peer rejection was highest among boys with chronic high aggression. Interventions with boys with distinct patterns of aggression are discussed.

The Association of Antisocial Behavior and Depressive Symptoms Between Partners and Risk for Aggression in Romantic Relationships.

This study examined the extent to which antisocial behavior and depressive symptoms were associated between romantic partners and whether the partner's antisocial behavior and depressive symptoms affected the individual's aggression toward the partner above and beyond the contribution of his or her own symptoms. Questions were examined concurrently and longitudinally for 79 couples from a young, at-risk sample. There were reliable associations between partners' antisocial behavior and depressive symptoms. Women's antisocial behavior and depressive symptoms were significantly related to concurrent levels of men's physical and psychological aggression. Women's depressive symptoms remained significant in predicting men's psychological aggression over time. Overall, men's risk factors had little effect on their partners' aggression. Findings suggest that interventions to reduce partner violence need to consider the potential influence of partner, as well as perpetrator characteristics.
