Female and male antisocial trajectories: from childhood origins to adult outcomes

Female juvenile delinquency, motherhood, and the intergenerational transmission of aggression and antisocial behavior

The current study explored the intergenerational transmission of aggression and antisocial behavior by examining mothers' juvenile delinquency, their pregnancies, and its impact on their children's aggressive behavior. The sample consisted of the first 181 biological mothers recruited as part of the Vancouver Longitudinal Study on the Psychosocial Development of Children (British Columbia, Canada). Results indicated that mothers who were juvenile delinquents were more likely to experience social adversity, to use substances during pregnancy and to offend in adulthood. Furthermore, mothers who reported juvenile delinquency had children who were more physically aggressive and had an earlier onset of physical aggression. This pattern of association held when controlling for sociodemographics, social adversities, prenatal substance exposure, and criminal involvement in adulthood. The study findings highlighted the importance of understanding the role and impact of female delinquency and motherhood on the intergenerational transmission of antisocial behavior.

ADHD and delinquency--a developmental perspective

Attention-deficit/hyperactivity disorder (ADHD) is one of the most prevalent psychiatric disorders of childhood and adolescence. Until now, it has been unclear whether ADHD by itself constitutes a risk factor for later delinquency or does so only in combination with other disruptive symptoms. This article seeks to give a comprehensive account of the literature to shed light on the developmental pathway from childhood ADHD to adult criminality. Comorbid ADHD and conduct disorder (CD) are significantly related to a range of biological and environmental risk factors such as neurocognitive impairment, high parental psychopathology, poor social functioning, and other comorbid mental disorders, particularly substance abuse, that are described in this review. In addition, the results of treatment studies are presented, with a special focus on the results of the Multimodal Treatment Study of Children with ADHD (MTA). Although treatment programs, including medication and psychosocial treatment, can be very effective in improving the functioning of children with ADHD in the social and academic domains in the short term, there is no conclusive evidence that such treatments lower the risk for developing delinquency in adulthood.

From correlates to causes: can quasi-experimental studies and statistical innovations bring us closer to identifying the causes of antisocial behavior?

Longitudinal, epidemiological studies have identified robust risk factors for youth antisocial behavior, including harsh and coercive discipline, maltreatment, smoking during pregnancy, divorce, teen parenthood, peer deviance, parental psychopathology, and social disadvantage. Nevertheless, because this literature is largely based on observational studies, it remains unclear whether these risk factors have truly causal effects. Identifying causal risk factors for antisocial behavior would be informative for intervention efforts and for studies that test whether individuals are differentially susceptible to risk exposures. In this article, we identify the challenges to causal inference posed by observational studies and describe quasi-experimental methods and statistical innovations that may move researchers beyond discussions of risk factors to allow for stronger causal inference. We then review studies that used these methods, and we evaluate whether robust risk factors identified from observational studies are likely to play a causal role in the emergence and development of youth antisocial behavior. There is evidence of causal effects for most of the risk factors we review. However, these effects are typically smaller than those reported in observational studies, suggesting that familial confounding, social selection, and misidentification might also explain some of the association between risk exposures and antisocial behavior. For some risk factors (e.g., smoking during pregnancy, parent alcohol problems), the evidence is weak that they have environmentally mediated effects on youth antisocial behavior. We discuss the implications of these findings for intervention efforts to reduce antisocial behavior and for basic research on the etiology and course of antisocial behavior.

Behavioural and cognitive-behavioural group-based parenting programmes for early-onset conduct problems in children aged 3 to 12 years

BACKGROUND

Early-onset child conduct problems are common and costly. A large number of studies and some previous reviews have focused on behavioural and cognitive-behavioural group-based parenting interventions, but methodological limitations are commonplace and evidence for the effectiveness and cost-effectiveness of these programmes has been unclear.

OBJECTIVES

To assess the effectiveness and cost-effectiveness of behavioural and cognitive-behavioural group-based parenting programmes for improving child conduct problems, parental mental health and parenting skills.

SEARCH METHODS

We searched the following databases between 23 and 31 January 2011: CENTRAL (2011, Issue 1), MEDLINE (1950 to current), EMBASE (1980 to current), CINAHL (1982 to current), PsycINFO (1872 to current), Social Science Citation Index (1956 to current), ASSIA (1987 to current), ERIC (1966 to current), Sociological Abstracts (1963 to current), Academic Search Premier (1970 to current), Econlit (1969 to current), PEDE (1980 to current), Dissertations and Theses Abstracts (1980 to present), NHS EED (searched 31 January 2011), HEED (searched 31 January 2011), DARE (searched 31 January 2011), HTA (searched 31 January 2011), mRCT (searched 29 January 2011). We searched the following parent training websites on 31 January 2011: Triple P Library, Incredible Years Library and Parent Management Training. We also searched the reference lists of studies and reviews.

SELECTION CRITERIA

We included studies if: (1) they involved randomised controlled trials (RCTs) or quasi-randomised controlled trials of behavioural and cognitive-behavioural group-based parenting interventions for parents of children aged 3 to 12 years with conduct problems, and (2) incorporated an intervention group versus a waiting list, no treatment or standard treatment control group. We only included studies that used at least one standardised instrument to measure child conduct problems.

DATA COLLECTION AND ANALYSIS

Two authors independently assessed the risk of bias in the trials and the methodological quality of health economic studies. Two authors also independently extracted data. We contacted study authors for additional information.

MAIN RESULTS

This review includes 13 trials (10 RCTs and three quasi-randomised trials), as well as two economic evaluations based on two of the trials. Overall, there were 1078 participants (646 in the intervention group; 432 in the control group). The results indicate that parent training produced a statistically significant reduction in child conduct problems, whether assessed by parents (standardised mean difference (SMD) -0.53; 95% confidence interval (CI) -0.72 to -0.34) or independently assessed (SMD -0.44; 95% CI -0.77 to -0.11). The intervention led to statistically significant improvements in parental mental health (SMD -0.36; 95% CI -0.52 to -0.20) and positive parenting skills, based on both parent reports (SMD -0.53; 95% CI -0.90 to -0.16) and independent reports (SMD -0.47; 95% CI -0.65 to -0.29). Parent training also produced a statistically significant reduction in negative or harsh parenting practices according to both parent reports (SMD -0.77; 95% CI -0.96 to -0.59) and independent assessments (SMD -0.42; 95% CI -0.67 to -0.16). Moreover, the intervention demonstrated evidence of cost-effectiveness. When compared to a waiting list control group, there was a cost of approximately $2500 (GBP 1712; EUR 2217) per family to bring the average child with clinical levels of conduct problems into the non-clinical range. These costs of programme delivery are modest when compared with the long-term health, social, educational and legal costs associated with childhood conduct problems.

AUTHORS' CONCLUSIONS

Behavioural and cognitive-behavioural group-based parenting interventions are effective and cost-effective for improving child conduct problems, parental mental health and parenting skills in the short term. The cost of programme delivery was modest when compared with the long-term health, social, educational and legal costs associated with childhood conduct problems. Further research is needed on the long-term assessment of outcomes.

Gene-environment interplay in the association between pubertal timing and delinquency in adolescent girls

Early pubertal timing places girls at elevated risk for a breadth of negative outcomes, including involvement in delinquent behavior. While previous developmental research has emphasized the unique social challenges faced by early maturing girls, this relation is complicated by genetic influences for both delinquent behavior and pubertal timing, which are seldom controlled for in existing research. The current study uses genetically informed data on 924 female-female twin and sibling pairs drawn from the National Longitudinal Study of Adolescent Health to (1) disentangle biological versus environmental mechanisms for the effects of early pubertal timing and (2) test for gene-environment interactions. Results indicate that early pubertal timing influences girls' delinquency through a complex interplay between biological risk and environmental experiences. Genes related to earlier age at menarche and higher perceived development significantly predict increased involvement in both nonviolent and violent delinquency. Moreover, after accounting for this genetic association between pubertal timing and delinquency, the impact of nonshared environmental influences on delinquency are significantly moderated by pubertal timing, such that the nonshared environment is most important among early maturing girls. This interaction effect is particularly evident for nonviolent delinquency. Overall, results suggest early maturing girls are vulnerable to an interaction between genetic and environmental risks for delinquent behavior.

Are the major risk/need factors predictive of both female and male reoffending?: a test with the eight domains of the level of service/case management inventory

The Level of Service/Case Management Inventory (LS/CMI) and the Youth version (YLS/CMI) generate an assessment of risk/need across eight domains that are considered to be relevant for girls and boys and for women and men. Aggregated across five data sets, the predictive validity of each of the eight domains was gender-neutral. The composite total score (LS/CMI total risk/need) was strongly associated with the recidivism of males (mean r = .39, mean AUC = .746) and very strongly associated with the recidivism of females (mean r = .53, mean AUC = .827). The enhanced validity of LS total risk/need with females was traced to the exceptional validity of Substance Abuse with females. The intra-data set conclusions survived the introduction of two very large samples composed of female offenders exclusively. Finally, the mean incremental contributions of gender and the gender-by-risk level interactions in the prediction of criminal recidivism were minimal compared to the relatively strong validity of the LS/CMI risk level. Although the variance explained by gender was minimal and although high-risk cases were high-risk cases regardless of gender, the recidivism rates of lower risk females were lower than the recidivism rates of lower risk males, suggesting possible implications for test interpretation and policy.

Childhood Maltreatment and Prospectively Observed Quality of Early Care as Predictors of Antisocial Personality Disorder Features

Few studies have evaluated the separate contributions of maltreatment and ongoing quality of parent-child interaction to the etiology of antisocial personality features using a prospective longitudinal design. 120 low-income young adults (aged 18-23) were assessed for extent of ASPD features on the Structured Clinical Interview for Diagnosis-Axis II, for presence of maltreatment on the Conflict Tactics Scale, Traumatic Experiences Scale, and Adult Attachment Interview, and for referral in infancy to parent-infant clinical services. Fifty-six of these families had been studied longitudinally since the first year of life. In infancy, attachment disorganization and disrupted mother-infant interaction were assessed; in middle childhood, disorganized-controlling attachment behaviors were reliably rated. In kindergarten and second grade, behavior problems were assessed by teacher report. In cross-sectional analyses, maltreatment was significantly associated with ASPD features but did not account for the independent effect of early referral to parent-infant services on ASPD features. In longitudinal analyses, maternal withdrawal in infancy predicted the extent of ASPD features twenty years later, independently of childhood abuse. In middle childhood, disorganized attachment behavior and maladaptive behavior at school added to prediction of later ASPD features. Antisocial features in young adulthood have precursors in the minute-to-minute process of parent-child interaction beginning in infancy.

Störungen des Sozialverhaltens

Dieser Beitrag diskutiert die prädiktive Validität der allgemeinen Diagnosekriterien von Störungen des Sozialverhaltens nach ICD-10 und DSM-IV-TR. Dabei wird Bezug genommen auf aktuelle Befunde, die eine Phänotypisierung früh beginnender Störungen des Sozialverhaltens auf der Basis neurobiologischer und persönlichkeitsspezifischer Faktoren nahelegen. Untersuchungsergebnisse, die auf defizitäre neurobiologische Mechanismen aggressiven Verhaltens in Bezug auf Prozesse der Emotionswahrnehmung und Emotionsregulation hinweisen, werden dargestellt, wobei auch die Bedeutung möglicher mediierender Einflüsse früher psychosozialer Erfahrungen auf neurobiologische Funktionen erörtert wird. Die klinischen Implikationen für die Klassifikation, den Verlauf und die Behandlung von Störungen des Sozialverhaltens werden abschließend diskutiert.

Current issues in the diagnosis of attention deficit hyperactivity disorder, oppositional defiant disorder, and conduct disorder

This review evaluates the diagnostic criteria for three of the most common disorders for which children and adolescents are referred for mental health treatment: attention deficit hyperactivity disorder (ADHD), oppositional defiant disorder (ODD), and conduct disorder (CD). Although research supports the validity and clinical utility of these disorders, several issues are highlighted that could enhance the current diagnostic criteria. For ADHD, defining the core features of the disorder and its fit with other disorders, enhancing the validity of the criteria through the lifespan, considering alternative ways to form subtypes of the disorder, and modifying the age-of-onset criterion are discussed relative to the current diagnostic criteria. For ODD, eliminating the exclusionary criteria of CD, recognizing important symptom domains within the disorder, and using the cross-situational pervasiveness of the disorder as an index of severity are highlighted as important issues for improving classification. Finally, for CD, enhancing the current subtypes related to age of onset and integrating callous-unemotional traits into the diagnostic criteria are identified as key issues for improving classification.

Expanding our lens: female pathways to antisocial behavior in adolescence and adulthood

Women and girls' engagement in antisocial behavior represents a psychological issue of great concern given the radiating impact that women's antisociality can have on individuals, families, and communities. Despite its importance and relevance for psychological science, this topic has received limited attention to date and no systematic review of risk factors exists. The present paper aims to systematically review the empirical literature informing risk factors relevant to women's antisocial behavior, with a focus on adolescence and adulthood. Primary aims are to 1) review empirical literatures on risk factors for female antisocial behavior across multiple levels of influence (e.g., person-level characteristics, risky family factors, and gender-salient contexts) and fields of study (e.g., psychology, sociology); 2) evaluate the relevance of each factor for female antisocial behavior; and 3) incorporate an analysis of how gender at both the individual and ecological levels shapes pathways to antisocial behavior in women and girls. We conclude that women's antisocial behavior is best-understood as being influenced by person-level or individual vulnerabilities, risky family factors, and exposure to gender-salient interpersonal contexts, and underscore the importance of examining women's antisocial behavior through an expanded lens that views gender as an individual level attribute as well as a social category that organizes the social context in ways that may promote engagement in antisocial behavior. Based on the present systematic review, an integrative pathway model is proposed toward the goal of synthesizing current knowledge and generating testable hypotheses for future research.

Developmental trajectories of child to adolescent externalizing behavior and adult DSM-IV disorder: results of a 24-year longitudinal study

OBJECTIVE

Childhood externalizing behavior is found to be relatively persistent. Developmental pathways within types of externalizing behavior have been recognized from childhood to adolescence. We aimed to describe the prediction of adult DSM-IV disorders from developmental trajectories of externalizing behavior over a period of 24 years on a longitudinal multiple birth cohort study of 2,076 children. This has not been examined yet.

METHODS

Trajectories of the four externalizing behavior types aggression, opposition, property violations, and status violations were determined separately through latent class growth analysis (LCGA) using data of five waves, covering ages 4-18 years. Psychiatric disorders of 1,399 adults were assessed with the CIDI. We used regression analyses to determine the associations between children's trajectories and adults' psychiatric disorders.

RESULTS

All externalizing behavior types showed significant associations with disruptive disorder in adulthood. In all antisocial behavior types high-level trajectories showed the highest probability for predicting adult disorders. Particularly the status violations cluster predicted many disorders in adulthood. The trajectories most often predicted disruptive disorders in adulthood, but predicted also anxiety, mood, and substance use disorders.

CONCLUSIONS

We can conclude that an elevated level of externalizing behavior in childhood has impact on the long-term outcome, regardless of the developmental course of externalizing behavior. Furthermore, different types of externalizing behavior (i.e., aggression, opposition, property violations, and status violations) were related to different adult outcomes, and children and adolescents with externalizing behavior of the status violations subtype were most likely to be affected in adulthood.

Developmental trajectories of aggression from late childhood through adolescence: similarities and differences across gender

Although numerous investigations of overt aggressive and antisocial trajectories have been undertaken, there is a dearth of literature examining gender differences and similarities in trajectory patterns and their correlates. To address these gaps, we investigated gender differences in the prevalence rates, predictive validity during transition to adulthood, childhood risk factors, and adolescent correlates of different trajectories of teacher-reported overt aggression (i.e., fights, argues, gets in trouble) among 220 participants (116 girls and 104 boys) evaluated annually from grade 4 to grade 12. Four patterns of trajectories were identified: low, increasing (i.e., adolescent-onset), decreasing (i.e., childhood-limited), and high (i.e., childhood-onset). A large proportion of youth, particularly girls, displayed low levels of aggression over time. A small proportion followed the childhood-onset trajectory. Across gender, the childhood-onset trajectory was associated with the highest rates of maladjustment during the transition to adulthood, the highest number of childhood risk factors, and multiple problems during adolescence. The adolescent-onset trajectory was associated with few childhood risk factors, but with high levels of independent status during adolescence. In contrast, the childhood-limited trajectory was associated with several childhood risk factors, but high levels of parental monitoring and school engagement during adolescence. Romantic involvement differentiated the adolescent-onset and childhood-limited trajectories among girls.

Preventing youth violence perpetration among girls

In the last 10 years, several reviews of research on violence among girls have been conducted. This research helps to determine the extent of girls' use of violence however, it has not been translated into effective prevention programs for girls. This article reviews the research on risk and protective factors associated with violence, with particular attention on factors unique to girls or shared between boys and girls. Individual risk factors for youth violence include hyperactivity/inattention/impulsivity, risk taking/sensation seeking, low academic achievement, exposure to stress and victimization, and early puberty. Parent-child relationships/parental monitoring and supervision, parent criminal and antisocial behavior, and family conflicts and instability have been found to be relationship-level risk factors. Peer risk factors include deviant peer affiliation and gang membership. Risk factors at the community level include economic deprivation; community disorganization; the availability of drugs, alcohol, and firearms; and neighborhood crime. This review also includes a description of program effects for girls within the Model and Promising Blueprints for Violence Prevention Initiative programs. Very few evaluations have examined program effectiveness in preventing violence among girls. More evaluation research is needed to determine if evidence-based programs have positive impact on reducing violence and related risk factors among girls.

Oppositional defiant disorder-gender differences in co-occurring symptoms of mental health problems in a general population of children

Informant- and gender-specific characteristics of Oppositional Defiant Disorder (ODD) and how these might relate to patterns of comorbidity need to be further clarified. We collected data from 7,007 children (aged 7-9) who participated in the Bergen Child Study (BCS), an ongoing population-based study of children's development and mental health. A questionnaire containing the DSM-IV behavioral descriptions of ODD was distributed to parents and teachers. Co-occurring symptoms of mental health problems were measured by the Strengths and Difficulties Questionnaire (SDQ). The boys (n = 122) and girls (n = 41) with symptomatic ODD had an increased risk of co-occurring emotional symptoms, hyperactivity or inattention and peer problems, as compared to their peers without symptomatic ODD. The impact of symptomatic ODD was higher for boys than girls in teacher reported SDQ ratings, except for emotional symptoms. There were no significant interaction effects of gender in parent SDQ ratings. Our results are contrary to the gender paradox hypothesis, which states that co-occurring symptoms of mental health problems are more frequent among girls with ODD as compared to boys with ODD.

Maternal characteristics predicting young girls' disruptive behavior

Little is known about the relative predictive utility of maternal characteristics and parenting skills on the development of girls' disruptive behavior. The current study used five waves of parent- and child-report data from the ongoing Pittsburgh Girls Study to examine these relationships in a sample of 1,942 girls from age 7 to 12 years. Multivariate generalized estimating equation analyses indicated that European American race, mother's prenatal nicotine use, maternal depression, maternal conduct problems prior to age 15, and low maternal warmth explained unique variance. Maladaptive parenting partly mediated the effects of maternal depression and maternal conduct problems. Both current and early maternal risk factors have an impact on young girls' disruptive behavior, providing support for the timing and focus of the prevention of girls' disruptive behavior.

Violence and Men’s Health

Although violence affects everyone, men’s health is disproportionately affected. To better understand the etiology of men’s violence, it is essential to comprehensively examine the factors influencing the development and trajectories of violence perpetration and victimization. This review offers a broad perspective on the burden of violence for men and the characteristics of individuals, relationships, communities, and society that combine to influence men’s experience with interpersonal violence, including child maltreatment, youth violence, intimate partner violence, and sexual violence. Men’s experience with violence is influenced by physiological, emotional, and behavioral factors; relationships with family and peers; and social norms. In collaboration with professionals from other sectors, health professionals can help prevent or intervene in male’s perpetration of violence across the lifespan through identification of factors that place men at risk and referral of male patients to evidence-based prevention and intervention resources.

Violent, nonviolent, and substance-related offending over the life course in a cohort of males and females treated for substance misuse as youths

Most studies on adolescent offending heterogeneity are based on general population samples, and few include individuals with substance misuse or look specifically at substance-related offending. It is also unclear how offender subtypes develop after young adulthood or how offending heterogeneity varies between genders. This study aimed to identify subgroups of offending among adolescents with misuse problems and to examine associations with offending in adulthood. The study included 1,992 females and males that consulted a clinic for adolescents with misuse problems between 1968 and 1971. Latent Class Analyses were conducted to identify subgroups based on violent and nonviolent offending before age 20. Participants were then followed until age 50 and reexamined regarding violent, nonviolent, and substance-related crimes. Associations between subgroups before age 20 and subgroups age 21-50 were examined. Before age 20, three subgroups were identified among the females and six among the males. Males were more specialized in their offending and demonstrated higher levels of offending. Results pointed to both stability and decrease of violent and nonviolent offending, and to the emergence of substance-related offending in adulthood in both genders. The connection between substance-related crimes and general delinquency in adulthood among individuals treated for substance misuse suggests that interventions should also address substance misuse for reducing the overall volume of crime. This study also highlights the importance of including females in research on offending heterogeneity.

Creating nurturing environments: a science-based framework for promoting child health and development within high-poverty neighborhoods

Living in poverty and living in areas of concentrated poverty pose multiple risks for child development and for overall health and wellbeing. Poverty is a major risk factor for several mental, emotional, and behavioral disorders, as well as for other developmental challenges and physical health problems. In this paper, the Promise Neighborhoods Research Consortium describes a science-based framework for the promotion of child health and development within distressed high-poverty neighborhoods. We lay out a model of child and adolescent developmental outcomes and integrate knowledge of potent and malleable influences to define a comprehensive intervention framework to bring about a significant increase in the proportion of young people in high-poverty neighborhoods who will develop successfully. Based on a synthesis of research from diverse fields, we designed the Creating Nurturing Environments framework to guide community-wide efforts to improve child outcomes and reduce health and educational inequalities.

Multi-Domain Risk and Protective Factor Predictors of Violent Behavior among At-risk Youth

This study extends prior examination of adolescent violence etiology, drawing on an ethnically diverse, community accessed, yet emotionally vulnerable sample (N = 849) of adolescents at-risk for school drop-out. A balanced risk and protective factor framework captured theorized dimensions of strain, coping, and support resources. We tested the combined and unique contribution of risk and protective components spanning individual, peer/school, and family predictor domains, including victimization histories. Hierarchical regressions yielded significant overall explanation of violent behaviors as well as unique predictors within each of the three domains. Tests for sex differences and moderating effects suggested that levels of risk and protective factors differed for males and females, although the functional relationships to violence were the same for both sexes. Results are discussed relative to prevention and early intervention programs; particularly the importance of understanding adolescent violent behaviors within a context that addresses stress and distress.

Social cognition and conduct problems: a developmental approach

OBJECTIVE

To estimate associations between trajectories of conduct problems and social-cognitive competences through childhood into early adolescence.

METHOD

A prospective population-based cohort, the Avon Longitudinal Study of Parents and Children (ALSPAC) recruited in the prenatal period (13,988 children alive at 12 months) formed the basis for the current study. Socio-emotional and pragmatic language competences were examined in relation to conduct problem development in a group of 6,047 children with no known autistic-spectrum disorders. Specifically, conduct problem trajectories (low, childhood-limited, adolescent-onset, and early-onset persistent) identified using maternal prospective reports (Strengths and Difficulties Questionnaire: ages 4 through 13 years) were contrasted. Demographic confounders, child verbal IQ and other psychopathologies were controlled.

RESULTS

In contrast to individuals with low conduct problem levels, all conduct problem groups presented with difficulties in both social-cognitive domains. Deficits among those with early-onset persistent conduct problems were particularly apparent: 40.6% of boys and 24.3% of girls with persistent conduct problems met impairment criteria for one or other social-cognitive domain. Associations remained robust after controlling for demographic confounders (maternal age at birth, low SES, maternal education), child verbal IQ, and internalizing and inattention symptoms. For boys, results indicated that overlaps with overactivity symptoms may contribute problems with pragmatic language; this was not the case for girls or for socio-emotional difficulties.

CONCLUSIONS

Findings have far-reaching implications for children with conduct problems, particularly those with early onset and persistent difficulties. Traditional parent training interventions are likely to be bolstered by strategies that help to develop the social competences of these children.

Deviant peer affiliation and antisocial behavior: interaction with Monoamine Oxidase A (MAOA) genotype

Although genetic and environmental factors are separately implicated in the development of antisocial behavior (ASB), interactive models have emerged relatively recently, particularly those incorporating molecular genetic data. Using a large sample of male Caucasian adolescents and young adults from the National Longitudinal Study of Adolescent Health (Add Health), the association of deviant peer affiliation, the 30-base pair variable number tandem repeat polymorphism in promoter region of the monoamine oxidase-A (MAOA) gene, and their interaction, with antisocial behavior (ASB) was investigated. Weighted analyses accounting for over-sampling and clustering within schools as well as controlling for age and wave suggested that deviant peer affiliation and MAOA genotype were each significantly associated with levels of overt ASB across a 6-year period. Only deviant peer affiliation was significantly related to covert ASB, however. Additionally, there was evidence suggestive of a gene-environment interaction (G × E) where the influence of deviant peer affiliation on overt ASB was significantly stronger among individuals with the high-activity MAOA genotype than the low-activity genotype. MAOA was not significantly associated with deviant peer affiliation, thus strengthening the inference of G × E rather than gene-environment correlation (rGE). Different forms of gene-environment interplay and implications for future research on ASB are discussed.

Time-varying associations between conduct problems and alcohol use in adolescent girls: the moderating role of race

OBJECTIVE

The aims of this study were to examine the time-varying developmental associations between conduct problems and early alcohol use in girls between ages 11 and 15 and to test the moderating role of race.

METHOD

The study is based on annual, longitudinal data from oldest cohort in the Pittsburgh Girls Study (n = 566; 56% African American, 44% White). Two models of the association between conduct problems and alcohol use were tested using latent growth curve analyses: conduct-problem-effect (conduct problems predict time-specific variation in alcohol use trajectory) and alcohol-effect (alcohol use predicts time-specific variation in conduct problem trajectory) models.

RESULTS

Girls' conduct problems and alcohol use increased over ages 11-15. Results provided support for a conduct-problem-effect model, although the timing of the associations between conduct problems and alcohol use differed by ethnicity. Among White girls, conduct problems prospectively predicted alcohol use at ages 11-13 but not later, whereas among African American girls, prospective prediction was observed at ages 13-14 but not earlier.

CONCLUSIONS

Study findings indicate developmental differences in the time-varying association of conduct problems and alcohol use during early adolescence for African American and White girls. Ethnic differences in the development of alcohol use warrant further study, and have potential implications for culture-specific early screening and preventive interventions.

Early intervention for at risk children: 3-year follow-up

Childhood behavioral and emotional symptoms are linked with distress and dysfunction that may persist into adulthood. Effective and practical early prevention could make a significant contribution to the well-being of individuals and the functioning of communities. School-based targeted interventions are relatively easy and inexpensive to deliver and have been shown to reduce symptoms in the short term. The current study evaluates the 2- and 3-year outcome of targeted school-based drama group therapy (DGT) as compared to teaching maths and English. It shows a rapid decline in teacher-observed behavioral symptoms following DGT. By a year post intervention, symptom rates following both interventions converged and remained low throughout follow-up. Drama group therapy is rapidly effective in reducing symptoms. However, the findings also suggest that despite differing content, school-based small-group interventions are likely to share some effective components.

Developmental trajectories of girls' and boys' delinquency and associated problems

Developmental trajectories in delinquency through adolescence were studied along with family and peer relationship problems. Drawing from eight waves of data over seven years, we conducted trajectory analyses with a sample of 746 students (402 girls; 344 boys). Analyzing girls and boys together, a five-class model emerged: 60% of the adolescents rarely reported delinquency; 27.7% reported low initial levels with moderate levels of delinquency over time; 6% in the late onset group reported initially low and rising levels of delinquency; 5% in the early onset group reported moderate initial levels which increased and then decreased in later adolescence. A small group of only boys (1.3%) labeled chronic reported high initial levels of delinquency that increased over time. Group comparisons revealed problems in internalizing, parent and peer relationship problems. The findings provide direction for early identification and interventions to curtail the development of delinquency.

Risk and protective factors associated with patterns of antisocial behavior among nonmetropolitan adolescents

This study used latent class analysis (LCA) to identify patterns of antisocial behavior (ASB) in a sample of 1,820 adolescents in a nonmetropolitan region of the Northeast. Self-reported ASBs including stealing, fighting, damaging property, and police contact were assessed. LCA identified four classes of ASB including a non-ASB class, a mild, a moderate, and a serious ASB class. Multinomial logistic regression indicated that parent-child relationships served as a protective factor against engaging in ASB and peer, school, and community risk and protective factors differentiated mild patterns of ASB from more intense patterns of involvment. These findings suggest utility in using the LCA to better understand predictors of adolescent ASB to inform more effective prevention and intervention efforts targeting youth who exhibit different patterns of behavior.

Effects of early prevention programs on adult criminal offending: a meta-analysis

This meta-analysis investigated the long term effects of prevention programs conducted during early and middle childhood on criminal offending during adulthood. The analyses included 3611 participants in 9 programs. The effect size for adult criminal offending was significant, but small in magnitude (OR=1.26; 95% CI=1.06-1.50, p=.011). The effects of the programs on positive outcomes (academic attainment and involvement in productive activity, such as being engaged in school or work) were somewhat larger and more consistent than effects on crime (OR=1.36, 95% CI=1.20-1.55, p<.001). Several participant and program characteristics moderated the effectiveness of (early) prevention. Children who were more at-risk and those from a lower SES benefited more. Shorter, but more intensive programs, and programs that focus on social and behavioral skills, rather than on academic skills or family support, tend to produce larger effects. Taken together, these results indicate that early prevention programs can help put children on a more positive developmental trajectory that is maintained into adulthood, but there is still no convincing evidence that they can prevent adult crime. Implications of the findings for research, policy and clinical practice are discussed.

Conduct disorder symptoms and subsequent pregnancy, child-birth and abortion: a population-based longitudinal study of adolescents

Research on teenage pregnancy and abortion has primarily focused on socio-economic disadvantage. However, a few studies suggest that risk of unwanted pregnancy is related to conduct disorder symptoms. We examined the relationship between level of conduct disorder symptoms at age 15 and subsequent pregnancy, child-birth and abortion. A population-based, representative sample of Norwegian adolescent girls (N = 769) was followed from early adolescence until their mid-20s. Even with control for socio-demographic and family variables, conduct disorder symptoms at age 15 were strongly associated with pregnancy in the 15-19 age group, and a weaker association persisted in the 20-28 age group. Similar results were obtained for abortions, but here a strong relationship with conduct disorder symptoms was found even after age 20. After adjustment, no significant association between conduct disorder symptoms and subsequent child-birth was observed. More targeted preventive programmes aimed at girls with conduct disorder symptoms may be warranted.

Morbidity and mortality risk among the "forgotten few": why are girls in the justice system in such poor health?

The present study assessed the physical health of a population of girls sentenced to custody in a large US State via medical examinations and clinical assessments in adolescence and young adulthood. Findings indicated that injuries, obesity, and sexually transmitted diseases were the norm, with over 50% of the population meeting criteria for each of these health problems. A dose-response relationship was documented between childhood victimization and injuries and injury risk in adolescence and self-harm, HIV risk, physical health symptoms, and hospitalizations in young adulthood. The relationship between childhood victimization and poor adult physical health was fully mediated by health-risk behaviors in adolescence. Clinical and policy implications of the high mortality and morbidity risk among female juvenile offenders are discussed.

Children's problems predict adults' DSM-IV disorders across 24 years

OBJECTIVE

The goal of this study was to determine continuities of a broad range of psychopathology from childhood into middle adulthood in a general population sample across a 24-year follow-up.

METHOD

In 1983, parent ratings of children's problems were collected with the Child Behavior Checklist (CBCL) in a general population sample of 2,076 children and young adolescents aged 4 to 16 years. In 2007, 24 years later, 1,339 of these individuals were reassessed with the CIDI, a standardized DSM-IV interview. We used univariate logistic regression analyses to determine the associations between children's problems and adults' psychiatric disorders.

RESULTS

Parent reported total problems scores in the deviant range (>85th percentile) predicted disruptive disorders in adulthood (odds ratio [OR] = 1.7, 95% confidence interval [95% CI] = 1.1-2.8). Adjusted for sex, age, and socioeconomic status in all analyses, deviant levels of parent-reported childhood anxiety predicted anxiety disorders in middle adulthood (OR = 1.6, 95% CI = 1.0-2.5). Conduct problems (i.e., cruelty to animals, lies) predicted both mood disorders (OR = 2.3, 95% CI = 1.1-4.8) and disruptive disorders (OR 2.1, 95% CI = 1.3-3.4), whereas oppositional defiant problems predicted only mood disorders (OR = 2.3, 95% CI = 1.0-5.2). Attention-deficit/hyperactivity problems did not predict any of the DSM-IV disorders in adulthood (OR = 0.8, 95% CI = 0.5-1.2).

CONCLUSIONS

Children with psychopathology are at greater risk for meeting criteria for DSM-IV diagnoses in adulthood than children without psychopathology, even after 24 years. Moreover, different types of continuities of children's psychopathology exist across the lifespan. We found that anxious children, oppositional defiant children, and children with conduct problems are at greater risk for adult psychopathology. Effective identification and treatment of children with these problems may reduce long-term continuity of psychopathology.

Co-occurring problems of early onset persistent, childhood limited, and adolescent onset conduct problem youth

BACKGROUND

It is increasingly recognized that youth who follow early onset persistent (EOP), childhood limited (CL) and adolescent onset (AO) trajectories of conduct problems show somewhat varying patterns of risk (in childhood) and adjustment problems (in adolescence and adulthood). Little, however, is known about how other adjustment problems differentially co-develop with the EOP, CL and AO trajectories across the childhood and adolescent years.

METHOD

Using data from the Avon Longitudinal Study of Parents and Children, an epidemiological, longitudinal cohort of boys and girls, we estimated growth curves for parent-reported hyperactivity, emotional difficulties, peer relational problems, and prosocial behaviors conditional on trajectories of conduct problems (i.e., EOP, CL and AO) from ages 4 to 13 years. At ages 7-8 years, DSM-IV-based diagnoses of conduct disorder, oppositional-defiant disorder, attention deficit/hyperactivity disorder (ADHD), anxiety, depression were examined by conduct problems trajectory.

RESULTS

Overall, the development of hyperactivity, emotional difficulties, peer relational problems, and prosocial behaviors mirrored the development of conduct problems, showing similar trajectories.

CONCLUSIONS

Results indicated that the problems of EOP youth were persistent across domains, CL youth showed decreased behavior problems while increasing in prosocial behaviors, and AO youth increased in adjustment problems after 10 years of age.

Trajectories of antisocial behaviour towards siblings predict antisocial behaviour towards peers

BACKGROUND

Young siblings' antisocial behaviour is common yet its impact has received relatively little research attention.

METHODS

We examined trajectories of antisocial behaviour for a socially diverse sample (n = 99, 58 boys and 41 girls) who were filmed with their older siblings (52 boys and 47 girls) at ages 3 and 6 and with unfamiliar peers at age 6. Latent growth models were used to analyse three indicators of antisocial behaviour (refusal to share/interact, bullying and harming).

RESULTS

The average trajectory of antisocial behaviour towards siblings was stable and particularly high for boys with brothers and for children of mothers with no educational qualifications. Sustained and escalating antisocial behaviours towards siblings predicted bullying and refusals to share/interact with unfamiliar peers, independent of associations with concurrent antisocial behaviour towards sibling.

CONCLUSIONS

These findings highlight the importance of a developmental perspective when examining antisocial behaviour between young siblings.

Latent class analysis of antisocial behavior: interaction of serotonin transporter genotype and maltreatment

To improve understanding about genetic and environmental influences on antisocial behavior (ASB), we tested the association of the 44-base pair polymorphism of the serotonin transporter gene (5-HTTLPR) and maltreatment using latent class analysis in 2,488 boys and girls from Wave 1 of the National Longitudinal Study of Adolescent Health. In boys, ASB was defined by three classes (Exclusive Covert, Mixed Covert and Overt, and No Problems) whereas in girls, ASB was defined by two classes (Exclusive Covert, No Problems). In boys, 5-HTTLPR and maltreatment were not significantly related to ASB. However, in girls, maltreatment, but not 5-HTTLPR, was significantly associated with ASB. A significant interaction between 5-HTTLPR and maltreatment was also observed, where maltreated girls homozygous for the short allele were 12 times more likely to be classified in the Exclusive Covert group than in the No Problems group. Structural differences in the latent structure of ASB at Wave 2 and Wave 3 prevented repeat LCA modeling. However, using counts of ASB, 5-HTTLPR, maltreatment, and its interaction were unrelated to overt and covert ASB at Wave 2 and only maltreatment was related to covert ASB at Wave 3. We discuss these findings within the context of sex differences in ASB and relevant models of gene-environment interplay across developmental periods.

Aggression

Bei aggressiven Verhalten im Kindes- und Jugendalter handelt es sich um eine besonders häufig auftretende und stabile Problematik. Entwicklungsmodelle aggressiven Verhaltens tragen dazu bei, dass Erscheinungsformen, komorbide Störungen und Verläufe präziser eingeordnet und fundierte Behandlungsprognosen erstellt werden können. Evidenzbasierte Präventions- und Behandlungsprogramme liegen altersspezifisch ausgestaltet vor. Aggressives Verhalten und die in der Regel auftretenden komorbiden Störungen stellen die höchsten Anforderungen an die Behandlung, wobei Therapieansätze langfristig und komplex (unter Einbezug des sozialen Umfeldes des Kindes) angelegt sein müssen.

Developmental trajectories of boys' and girls' delinquency: sex differences and links to later adolescent outcomes

This study examined gender differences in trajectories of delinquent behaviors over a 6-year period in adolescence and differential outcomes of these diverse developmental pathways. Participants were 754 children who were part of a longitudinal study of the development of early starting conduct problems. Four trajectory patterns were identified across grades 7-12: increasing, desisting, chronic, and nonproblem groups. Although the proportion of boys and girls varied across the pathways, both genders were represented on these trajectories. Boys were more represented on the chronic and desisting trajectories; girls were more represented in the nonproblem group. However, the proportion of boys and girls was similar in the increasing trajectory. Trajectory membership significantly predicted age 19 outcomes for partner violence, risky sexual behavior and depression, and the risk conferred on these negative adjustment outcomes did not vary by gender. The overall pattern was characterized by poor outcomes at age 19 for youth in both the chronic and the increasing trajectories. The major conclusion is that, other than base rate differences, developmental patterns and outcomes for girls mimic those previously found for boys.

Group-based trajectory modeling in clinical research

Group-based trajectory models are increasingly being applied in clinical research to map the developmental course of symptoms and assess heterogeneity in response to clinical interventions. In this review, we provide a nontechnical overview of group-based trajectory and growth mixture modeling alongside a sampling of how these models have been applied in clinical research. We discuss the challenges associated with the application of both types of group-based models and propose a set of preliminary guidelines for applied researchers to follow when reporting model results. Future directions in group-based modeling applications are discussed, including the use of trajectory models to facilitate causal inference when random assignment to treatment condition is not possible.

Antisocial Behavioral Syndromes in Adulthood and Alcohol Use Disorder Treatment over Three-Year Follow-Up: Results from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions

BACKGROUND

Antisocial personality disorder (ASPD) is associated with poorer treatment outcomes, but more help seeking, for alcohol use disorders (AUDs); however, associations of ASPD with AUD treatment in the general population have not been studied prospectively.

OBJECTIVE

To examine prediction of treatment over 3-year follow-up among adults with AUDs by baseline ASPD and syndromal adult antisocial behavior without conduct disorder before age 15 (AABS).

METHOD

Face-to-face interviews with 34,653 respondents to the National Epidemiologic Survey on Alcohol and Related Conditions, of whom 3875 had prevalent AUDs between Waves 1 and 2 and ASPD, AABS, or no antisocial syndrome at Wave 1.

RESULTS

In unadjusted analyses, baseline ASPD predicted AUD treatment but AABS did not. After adjustment for additional need, predisposing, and enabling factors, antisocial syndromes did not predict treatment. Baseline predictors of treatment included more past-year AUD symptoms, and past-year nicotine dependence and AUD treatment.

CONCLUSIONS

That baseline antisocial syndrome did not predict AUD treatment may reflect strong associations of antisociality with previously identified predictors of help seeking.

Predicting adult emotional and behavioral problems from externalizing problem trajectories in a 24-year longitudinal study

The aim of this study was to examine the prediction of adult behavioral and emotional problems from developmental trajectories of externalizing behavior in a 24-years longitudinal population-based study of 2,076 children. The adult psychiatric outcome of these trajectories has not yet been examined. Trajectories of the four externalizing behavior types: aggression, opposition, property violations and status violations were determined separately through latent class growth analysis using data of five waves, covering ages 4-18 years. We used regression analyses to determine the associations between children's trajectories and adults' psychiatric problems based on the Adult Self-Report. The developmental trajectories of the four types of externalizing behavior mostly predicted intrusive, aggressive and rule-breaking behavior in adulthood. Non-destructive behaviors in childhood such as opposition and status violations predict adult problems to a larger extent than destructive behaviors such as aggression and property violations. In general, children who develop through high-level trajectories are likely to suffer from both internalizing and externalizing problem behavior in adulthood, regardless the direction of change (i.e. increasing/decreasing/persisting) of the high-level trajectory. We can conclude that the level rather than the developmental change of externalizing behavior problems has a larger impact on adult outcome.

Do antisocial females exhibit poor outcomes in adulthood? An Australian cohort study

OBJECTIVE

Antisocial behaviour in young people is common and associated with adverse effects in adulthood. The question whether these effects are observed in both genders remains controversial. A typology of antisocial behaviour that captures childhood limited (CL), adolescent onset (AO) and life course persistent behaviour (LCP) through both developmental stages is utilized to examine young adult outcomes in both sexes.

METHODS

The Mater-University of Queensland Study of Pregnancy (MUSP) data set is a longitudinal study following up a cohort of 7223 infants and mothers from antenatal care to the child's 21st year. Data on child antisocial behaviour was collected at ages 5 and 14 years. At the 21-year follow up, self-reported outcomes were collected on antisocial behaviour, use of alcohol, tobacco and cannabis, physical and mental health functioning. The relationship between the three antisocial sub-types and negative young adult outcomes was examined for both males and females using a series of logistic regressions.

RESULTS

Complete data across 21 years was available for 3173 participants. Males experienced higher levels of antisocial behaviour. In both males and females, AO and LCP groups exhibited elevated risk of negative outcomes including continuing antisocial behaviour, cannabis use, general health problems and depression/anxiety symptoms. The CL group exhibited poorer outcomes in physical and mental health but not in other domains.

CONCLUSION

Both males and females exhibiting AO and LCP antisocial behaviour are at increased risk of serious adverse outcomes in young adulthood. The significant loss to follow up of high-risk groups suggests the important relationship between early antisocial behaviour and problems in adulthood have been underestimated. Further research is required to understand antisocial behaviour in adolescence, identify factors that reinforce its continuity into adulthood, and identify interventions which are able to modify adult outcomes.

Trajectories of resilience over 25 years of individuals who as adolescents consulted for substance misuse and a matched comparison group

AIMS

To examine trajectories of resilience over 25 years among individuals who as adolescents received treatment for substance misuse, the clinical sample (CS) and a matched general population sample (GP).

DESIGN

Comparison of the CS and GP over 25 years using Swedish national registers of health care and criminality.

SETTING

A substance misuse clinic for adolescents in an urban area in Sweden.

MEASUREMENTS

Resilience was defined as the absence of substance misuse, hospitalizations for physical illnesses related to substance misuse, hospitalization for mental illness and law-abiding behaviour from ages 21 to 45 years.

PARTICIPANTS

The CS included 701 individuals who as adolescents had consulted a clinic for substance misuse. The GP included 731 individuals selected randomly from the Swedish population and matched for age, sex and birthplace.

FINDINGS

A total of 52.4% of the GP and 24.4% of the CS achieved resilience in all domains through 25 years. Among the CS, another one-third initially displayed moderate levels of resilience that rose to high levels over time, one-quarter displayed decreasing levels of resilience over time, while 9.3% showed little but improving resilience and 8.8% showed no resilience. Levels of resilience were associated with the severity of substance misuse and delinquency in adolescence.

CONCLUSIONS

Individuals who had presented substance misuse problems in adolescence were less likely to achieve resilience over the subsequent 25 years than was a matched general population sample, and among them, four distinct trajectories of resilience were identified. The severity and type of problems presented in adolescence distinguished the four trajectories.

Sex Differences in Trajectories of Offending Among Puerto Rican Youth

Although sex is one of the strongest correlates of crime, contentions remain regarding the necessity of sex-specific theories of crime. The current study examines delinquent trajectories across sex among Puerto Rican youth socialized in two different cultural contexts (Bronx, United States and San Juan, Puerto Rico). Results indicate: similar substantive offending trajectories across males and females within each cultural context; that males exhibit a higher frequency of offending and higher levels of risk factors for delinquency; and there more similarities than differences in how risk/protective factors relate to patterns of offending across male versus female youth. Study limitations and implications for sex-specific criminological theories are also discussed.

Sex Similarities/Differences in Trajectories of Delinquency among urban Chicago Youth: The Role of Delinquent Peers

A growing body of literature has recently emerged examining sex-specific pathways of offending. Yet, despite significant gains, this area of research is still rather underexplored. With a particular focus on the role of delinquent peers, this current study investigates the sex similarities/differences in offending trajectories among a large sample of urban Chicago male and female youth (n=3,038) from 6th through 8th grade (e.g., ages 12-14). The results suggest that the pathways of offending appear to be more similar than different across sex, and that associating with delinquent peers is significantly related to baseline delinquency. Furthermore, delinquent peers significantly distinguished the moderate and high-rate trajectory groups from the non-delinquents for both males and females, yet once estimated in a more fully specified model, the role of delinquent peers appeared to be indirect (operating through its effect on baseline delinquency). Study limitations and implications for theory and policy are also discussed.
