The Twelfth Jack Tizard Memorial Lecture. The development of offending and antisocial behaviour from childhood: key findings from the Cambridge Study in Delinquent Development

The Association Between Adverse Childhood Experiences and Different Types of Offending Behavior: An Examination Across Two Generations of British Males

Research has established a relationship between trauma exposure, often conceptualized as Adverse Childhood Experiences (ACEs), and offending, with some evidence suggesting that both trauma and offending can be transmitted from one generation to the next. Further, while some evidence suggests that experiencing a high number of ACEs is associated with different types of offenses, it is not known whether these associations are similar across generations. The current study aims to address this gap in knowledge by examining the effects of ACEs on different offense types across two generations, utilizing data from a longitudinal study of British male participants and their male children. Results suggest that high ACE scores are associated with several offense types within generations, but the effect of parental ACEs on the subsequent generation's offending was weak. Alongside a discussion of these findings, study limitations and future research directions are also presented.

Interactions Between Child-Rearing and Other Risk Factors in Predicting Delinquency, and Implications for Prevention

This article aims to identify interactions between harsh discipline and poor supervision and other childhood risk factors (all measured at age 8-10) in predicting delinquency. It analyzes data collected in the Cambridge Study in Delinquent Development (CSDD), which is a prospective longitudinal study of 411 London males first assessed at age 8. Of these males, 26% were convicted between ages 10 and 17. Harsh discipline and poor supervision significantly predicted delinquency, as did 16 other childhood risk factors. Generally, harsh discipline predicted delinquency more strongly in the presence of other risk factors, whereas poor supervision predicted delinquency more strongly in the absence of other risk factors. It is suggested that parent training programs targeting harsh discipline should focus particularly on children and families who possess other risk factors, whereas parent training programs targeting poor supervision should focus particularly on children and families who do not possess other risk factors.

The transition of Chilean adolescents from the child welfare system to the adolescent justice system: a continuation or an accumulation of adverse factors?

Research on juvenile delinquency and adolescent maladjustment indicates that the beginning of these processes is found in the relationship between multiple risk factors at the individual, family and community levels in this population. The objective of this research was to analyze the risk factors related to the transition from the child welfare system to the adolescent justice system in a group of Chilean male adolescents (n = 108), aged 14-18 years, grouped according to their membership in the child welfare system, the adolescent justice system or both systems. Through a quantitative methodology, variables associated with risk factors were examined by means of the Risk and Resource Evaluation Form FER-R and the Risk and Criminogenic Needs Inventory IRNC instruments. Logistic regression analysis found that the adolescent population within the child welfare system was more likely to enter the adolescent justice system if the following risk factors were present: weak family supervision, consumption of drugs, socially maladaptive peer relationships, and risky free time. These results emphasize that child welfare system interventions should focus on parental support and the management of socio-community networks to prevent re-entry of the adolescent population into the justice system.

Health of Convicted Persons in the Third Generation of the Longitudinal Cambridge Study in Delinquent Development

Research suggests that convicted persons are more likely than non-convicted persons to suffer poor health. However, few longitudinal studies have investigated associations between health and offending across generations. Using the Cambridge Study in Delinquent Development, this article prospectively investigates the relationship between health and offending across generations and between genders. At the average age of 25, third generation convicted males and females reported a higher incidence of serious drug use than non-convicted persons. Convicted males reported a higher incidence of mental illness and self-harm, whereas convicted females reported a lower incidence of physical illness, mental illness, self-harm and hospitalizations when compared to non-convicted females. Convicted males reported a higher incidence of industrial accidents, sports injuries and fight injuries, but a lower incidence of road accidents, whereas convicted females were more likely to report road accidents. Like their fathers, convicted males show worse health compared to non-convicted individuals.

Suubi4StrongerFamilies: A study protocol for a clustered randomized clinical trial addressing child behavioral health by strengthening financial stability and parenting among families in Uganda

Background

Children in Sub-Saharan Africa are burdened by significant unmet mental health needs. Across the region, high rates of poverty, HIV/AIDS, food insecurity, stigma, and an inadequate health safety net system exacerbate serious child behavioral health needs and impede an effective response. Disruptive behavioral disorders are particularly concerning as they persist through adolescence and adulthood. Hence, addressing the context-specific social influences on child behavioral health is critical given that children in the region comprise more than half of the total regional population. Against this backdrop, this study protocol describes a randomized clinical trial that will examine the mechanisms by which economic empowerment and family strengthening interventions targeting social, familial, and context-specific drivers affect the mental health of children in Uganda.

Methods

The study uses an experimental, longitudinal design across 30 cluster-randomized primary schools to compare single and combination intervention options; influences of economic empowerment and family strengthening on economic, perceptual, and functioning mediators; and context-specific moderators. The study will be conducted with 900 Ugandan children in mid-upper primary school (10-14 years). The three study conditions (n = 300 each) are: (1) economic empowerment only (EE only), (2) multiple family group-based family strengthening only (MFG-based FS only), and (3) combined EE + MFG-based FS. The interventions will be provided for 12 months; and assessments will occur at baseline, 12, 24, and 36 months.

Conclusion

Children in Sub-Saharan Africa are burdened by significant unmet mental health needs, including disruptive behavior disorders that persist through adolescence and adulthood if left untreated. The proposed study will examine the mechanisms by which economic empowerment and family strengthening interventions targeting social, familial and context-specific drivers affect the mental health of children in mid-upper primary schools in Uganda. Findings from this study can inform group, community, and population approaches that are needed for scalable solutions to address the social drivers negatively impacting child behavioral health in low-resource settings, including in Sub-Saharan Africa.

Intergenerational Continuity of Intimate Partner Violence Perpetration: An Investigation of Possible Mechanisms

Intimate partner violence (IPV) is a continuum of abuse that is associated with a number of negative outcomes including substance misuse, depression, and suicidal ideation. This study aims to investigate the intergenerational transmission of IPV perpetration and the mechanisms involved. Intergenerational transmission was investigated using information from two generations of the Cambridge Study in Delinquent Development which is a prospective longitudinal study of 411 males from an inner London area in the UK who have been followed up over a period of 50 years. Information with regard to IPV perpetration, specifically physical violence, was garnered from self-reports by the male at age 32, from their female partner at age 48, and from their male and female children in early adulthood. Regression analyses were used to investigate intergenerational transmission and examine whether psychosocial risk factors could be identified as potential intergenerational pathways. Having a father who was a perpetrator of IPV significantly increased the odds of daughters being perpetrators by 2 times. It did not significantly increase the odds for sons. The intergenerational transmission of IPV perpetration remains between fathers and their daughters over and above a series of psychosocial factors such as accommodation problems and alcohol misuse. Identification of factors associated with the intergenerational transmission of IPV perpetration will inform practitioners and policymakers. Information garnered from studies such as this may contribute to the development of prevention and intervention strategies for those at risk.

Intergenerational transmission of personality disorder severity and the role of psychosocial risk factors

BACKGROUND

Familial influences on the development of many psychopathologies are well recognised, yet the psychosocial risk factors that could help explain apparently intergenerational continuities of personality disorder (PD) are less well understood.

AIMS

To establish whether there is an association between the severity of PD in men and their offspring in a community cohort, and whether factors recognised as having the potential to increase risk of psychopathology mediate this.

METHODS

Participants in the Cambridge Study in Delinquent Development (n = 452 dyads) were assessed using the Tyrer and Johnson model of PD severity. Severe PD was defined as antisocial PD plus at least one other PD from a different cluster. Original participants were assessed by interview and their offspring by screening questionnaire. Chi-square tests and mediation models were used to investigate the intergenerational continuity of PD severity and its relationship with psychosocial risk factors.

RESULTS

An association between severe PD in fathers and severe PD in their offspring was confirmed, regardless of whether the offspring were male or female. Whilst preliminary tests suggested that employment problems, poor parental supervision and family disruption we associated with severe PD in daughters, mediation analysis suggested that these variables had very little effect once severity of father's disorder was in the model.

CONCLUSIONS

Psychosocial risk factors appear to play a limited role in the intergenerational transmission of PD severity, although future studies should take account of interaction data, for example, quality and quantity of paternal interaction given a child's temperamental traits.

Association of subcortical gray-matter volumes with life-course-persistent antisocial behavior in a population-representative longitudinal birth cohort

Neuropsychological evidence supports the developmental taxonomy theory of antisocial behavior, suggesting that abnormal brain development distinguishes life-course-persistent from adolescence-limited antisocial behavior. Recent neuroimaging work confirmed that prospectively-measured life-course-persistent antisocial behavior is associated with differences in cortical brain structure. Whether this extends to subcortical brain structures remains uninvestigated. This study compared subcortical gray-matter volumes between 672 members of the Dunedin Study previously defined as exhibiting life-course-persistent, adolescence-limited or low-level antisocial behavior based on repeated assessments at ages 7-26 years. Gray-matter volumes of 10 subcortical structures were compared across groups. The life-course-persistent group had lower volumes of amygdala, brain stem, cerebellum, hippocampus, pallidum, thalamus, and ventral diencephalon compared to the low-antisocial group. Differences between life-course-persistent and adolescence-limited individuals were comparable in effect size to differences between life-course-persistent and low-antisocial individuals, but were not statistically significant due to less statistical power. Gray-matter volumes in adolescence-limited individuals were near the norm in this population-representative cohort and similar to volumes in low-antisocial individuals. Although this study could not establish causal links between brain volume and antisocial behavior, it constitutes new biological evidence that all people with antisocial behavior are not the same, supporting a need for greater developmental and diagnostic precision in clinical, forensic, and policy-based interventions.

Out with “Fine Time,” in with Financial Waivers: Recent Developments in Massachusetts Probation Fines and Fees Policies

The criminal justice system routinely imposes financial sanctions on probation clients. These fines, fees, and restitution debts often amount to more than what many clients can reasonably afford to pay. Until recently, Massachusetts courts have incarcerated clients solely for their inability to pay these debts in a practice known as “fine time”. In 2018, the state passed a landmark criminal justice reform bill that restricted the types of cases in which fine time can be ordered. Clients that can establish that payment would lead to financial hardship can now petition the court for a financial waiver accompanied by community service. The current study seeks to explore the implications of the recent reform efforts on probation services by analyzing surveys gathered from a sample of 121 Massachusetts probation officers in 2020. Descriptive findings of officers’ attitudes toward fines and fees, responses to nonpayment by clients, and the use of financial waivers are presented. Officers’ perceptions and practices align with the recent reform efforts, suggesting support among probation personnel for policies that limit punitive responses to nonpayment of legal debts by their supervisees. Possible directions for future research and policy development are discussed.

Stability of psychopathy in a prospective longitudinal study: Results from the Cambridge Study in delinquent development

To further understand psychopathy within a Developmental and Life-Course Criminology perspective, the current article investigates the stability and change in psychopathy from childhood to middle age. The Cambridge Study in delinquent development is a prospective longitudinal study of 411 males, where psychopathy was coded based on contemporanously collected data from young people and in adulthood. Psychopathy in middle age was assessed in a medical interview. The findings indicate a high degree of stability of psychopathy across the life-course. To explain stability and change, childhood factors that might predict this were investigated. Few factors were related to stability and change across the life-course. Poor supervision, poor housing, a large family, and having a convicted father were associated with any change. A depressed mother was associated with a later decrease in psychopathy. This investigation has implications not only for the downward extension of psychopathy to childhood, but also for the understanding of the development of criminal and antisocial behavior.

Patterns of Homotypic and Heterotypic Continuity Between ADHD Symptoms, Externalising and Internalising Problems from Age 7 to 15

ADHD presents a serious community-health problem through its links to a wide range of negative outcomes. These outcomes are exacerbated when ADHD symptoms co-occur with other mental health problems. Research evidence suggests high rates of co-comorbidity with a range of problems. However, there is a paucity of longitudinal research that examines the predictive links between ADHD symptoms and symptoms of other mental health problems. We examined a cross-lagged autoregressive model in order to assess homotypic and heterotypic continuity between ADHD symptoms, aggressive behavior, non-aggressive behavior problems and anxiety/depression in a community-based sample of 1571 youth (761 female, 810 male) assessed annually from age 7 to 13 and again at age 15. Consistently significant correlations between each pair of problem behaviors provided support for concurrent comorbidity. Furthermore, significant autoregressive pathways provided support for homotypic continuity. Support for heterotypic continuity was limited to ADHD symptoms predicting both aggressive behavior and non-aggressive behavior problems, but not vice versa. Our study highlights the importance of focusing on ADHD symptoms to identify children at risk not only for continued ADHD symptomatology but also a range of externalizing behavior problems including different types of aggression and non-aggressive behavior problems, such as rule-breaking. Identifying these patterns in a community-based sample provides support for the possibility of early identification of risk for a range of problem  behaviors.

Adaptation and Implementation of the Multiple-Family Group Intervention in Ghana

BACKGROUND

The health system in Ghana is severely underequipped to meet the needs of children with behavioral health problems. A substantial treatment gap exists among individuals with behavioral challenges, necessitating the implementation of an evidence-based intervention to address child behavioral challenges in Ghana. This article presents learning opportunities from the adaptation and initiation process of an evidence-based approach, the multiple-family group (MFG) intervention, aimed at addressing child behavioral challenges in northern Ghana.

METHODS

The MFG intervention will be tested and implemented in three schools selected through a clustered randomization process, with 60 child-caregiver dyads per school. Each school will be assigned to MFG delivery by parent peers, MFG delivery by School Health Education Program (SHEP) coordinators, or an intervention where students are supplied only with mental health wellness materials and educational supports. The providers will be assessed on a fidelity measure.

RESULTS

The approach of engaging stakeholders in Ghana is anticipated to prove challenging because multiple partners are involved in MFG implementation. Participants are expected to actively participate, however, given some changes to the protocol to adapt it to the Ghanaian context, including the types of MFG facilitators and sample size. Other anticipated challenges include obtaining permission from key partners such as the education authorities, timing of the study within the academic calendar in Ghana, and meeting the high expectations of school authorities for the study.

NEXT STEPS

The MFG intervention will be delivered by parent peers and SHEP coordinators at the selected schools.

Teacher-rated aggression and co-occurring behaviors and emotional problems among schoolchildren in four population-based European cohorts

Aggressive behavior in school is an ongoing concern. The current focus is on specific manifestations such as bullying, but the behavior is broad and heterogenous. Children spend a substantial amount of time in school, but their behaviors in the school setting tend to be less well characterized than at home. Because aggression may index multiple behavioral problems, we used three validated instruments to assess means, correlations and gender differences of teacher-rated aggressive behavior with co-occurring externalizing/internalizing problems and social behavior in 39,936 schoolchildren aged 7-14 from 4 population-based cohorts from Finland, the Netherlands, and the UK. Correlations of aggressive behavior were high with all other externalizing problems (r: 0.47-0.80) and lower with internalizing problems (r: 0.02-0.39). A negative association was observed with prosocial behavior (r: -0.33 to -0.54). Mean levels of aggressive behavior differed significantly by gender. Despite the higher mean levels of aggressive behavior in boys, the correlations were notably similar for boys and girls (e.g., aggressive-hyperactivity correlations: 0.51-0.75 boys, 0.47-0.70 girls) and did not vary greatly with respect to age, instrument or cohort. Thus, teacher-rated aggressive behavior rarely occurs in isolation; boys and girls with problems of aggressive behavior likely require help with other behavioral and emotional problems. Important to note, higher aggressive behavior is not only associated with higher amounts of other externalizing and internalizing problems but also with lower levels of prosocial behavior.

Does Educational Success Mitigate the Effect of Child Maltreatment on Later Offending Patterns?

Analyses examined offending patterns during adolescence and adulthood and their relation to child maltreatment subtypes and education factors measured during adolescence and adulthood. A total of 356 participants were followed from preschool to adulthood in a prospective longitudinal study. Child maltreatment subtypes include physical-emotional abuse, sexual abuse, and neglect. Offending patterns were analyzed as latent classes of (a) chronic offending, (b) desistence, and (c) stable low-level or non-offending. Physical-emotional and sexual abuse were associated with a higher likelihood of chronic offending relative to stable low-level offending. Education variables, including high educational engagement and good academic performance, predicted a higher likelihood of low-level offending relative to desistence, but not desistence relative to chronic offending. Only educational attainment predicted desistence relative to chronic offending. There was no moderating effect of education variables on the association between child maltreatment subtypes and later offending patterns. Implications for research, practice, and policy are discussed.

A Phenomenological Study of Immigrant Parents of Adolescents with Delinquent Behavior in Israel

Scarce qualitative literature has focused on understanding the perspective of parents of adolescents involved in crime, and no prior literature has examined how the status of being a parent of an adolescent who is involved in delinquency intersects with being an immigrant parent. The current phenomenological study examined, through the eyes of immigrant parents, how they comprehend their children's involvement in delinquent behavior. This study examined in-depth semistructured interviews conducted with fourteen immigrant parents (10 mothers and 4 fathers) from the former Soviet Union in Israel of children treated in rehabilitation facilities for delinquent youth. Data analysis revealed a gradual decline in children's behavior ascribed to the developmental stage of adolescence, the pressures of immigration, and cultural conflict. These three factors are interwoven together to create a fabric within which they see their children turning to crime. Parents' gradual loss of control is balanced by attempts to idealize the parent-child relationship and to minimize the severity of the offenses committed. They describe various differing and even contradictory experiences of themselves as parents and their struggles to piece together incohesive, alternating experiences of themselves as parents. Despite the critical role they can play in their children's rehabilitation, as well as the distress that they themselves experience, parents of children involved in delinquent behavior have often been ignored in research. Acknowledging parents' perspectives and experiences can allow development of appropriate therapeutic strategies to support them and maximize their abilities to support their children.

Childhood risk factors for criminal career duration: Comparisons with prevalence, onset, frequency and recidivism

It has been argued that the predictors of all criminal career features are the same, and that childhood risk factors do not predict life-course-persistent offenders. Little is known about childhood predictors of the duration of criminal careers. The aim is to investigate childhood (aged 8-10 years) risk factors for criminal career duration, in comparison with childhood risk factors for other criminal career features. The Cambridge Study in Delinquent Development is a prospective longitudinal survey of 411 South London males from age 8, with conviction records up to age 61. Life-course-persistent (LCP) offenders were defined as those with a criminal career lasting at least 20 years. The strongest predictors of LCP offenders were harsh discipline, poor parental supervision, a convicted father and parental conflict. Childhood risk factors for LCP offenders and criminal career duration were different from childhood risk factors for the prevalence of offending (convicted versus unconvicted males). These results should be taken into account in developmental and life-course criminology theories, risk assessment instruments and risk-focused interventions.

Relation between basal cortisol and reactivity cortisol with externalizing problems: A systematic review✰

Delinquent behavior describes one of the most severe forms of antisocial and aggressive behavior, causing the highest mental health and public expenditures of problematic behavior in adolescence. Literature suggests that different concentrations of cortisol may serve as a biological marker for a severe antisocial subgroup of adolescents, although from the environmental risk factors that play a role in the development of severe delinquent and aggressive behavior, other neurobiological factors may be important. This review aims to analyze the association of cortisol levels with the development of delinquent behavior. Studies related to the topic were obtained from multiple databases, through rigorous exclusion and inclusion criteria. Only papers with empirical and quantitative methodologies from scientific and academic publications were included. Aims, methodological aspects (sample and instruments), and main conclusions were extracted from each study. Overall, the data suggest that regardless of the literature relating low cortisol levels to conduct problems and antisocial behavior, the lack of consensus in the examined studies demonstrates that more studies are needed to reveal the role of biosocial mechanisms in this hormonal-behavior link, and how these mechanisms are involved in establishing and maintaining delinquent behavior.

Endocrine markers of puberty timing and antisocial behaviour in girls and boys

BACKGROUND

Early puberty is associated with higher than average risk of antisocial behaviour, both in girls and boys. Most studies of such association, however, have focused on psychosocial mediating and moderating factors. Few refer to coterminous hormonal measures.

AIM

The aim of this review is to consider the role of hormonal markers as potential mediating or moderating factors between puberty timing and antisocial behaviour.

METHOD

A systematic literature search was conducted searching Medline, Embase, Web of Science, Scopus, Psycinfo, Cochrane and Google Scholar.

RESULTS

Just eight studies were found to fit criteria, all cross-sectional. Measurements were too heterogeneous to allow meta-analysis. The most consistent associations found were between adrenal hormones-both androgens and cortisol-which were associated with early adrenarche and antisocial behaviours in girls and later adrenarche and antisocial behaviour in boys.

CONCLUSIONS

The findings from our review suggest that longitudinal studies to test bidirectional hormone-behaviour associations with early or late puberty would be worthwhile. In view of the interactive processes between hypothalamic-pituitary-adrenal and hypothalamic-pituitary-gonadal axes, integrated consideration of the hormonal end products is recommended.

Conceptualising social and communication vulnerabilities among detainees in the criminal justice system

More people with autism spectrum disorder (ASD) are now being identified in the criminal justice system, and in parallel with this increase, the prevalence of ASD in the community has risen more than 150 % in the same time period. In this article, I will argue that this increase is due to a reclassification of those individuals whose social, communicative and behavioural function is at the lower end of the normal range. Put simply, extremes of these quantitative traits are now being conceptualised as 'disorder'. This has particular relevance for the criminal justice system as such traits are over-represented in this population: as such, it is likely that increasing numbers of people who are incarcerated will receive an ASD diagnosis. This will have major implications for where best, and how best, to manage such individuals using a framework of 'disorder' versus 'difference'.

Prospective Risk and Protective Factors for Juvenile Arrest Among Youth At Risk for Maltreatment

This study aimed to prospectively identify ecological risk factors for juvenile arrest in a sample of youth at risk for maltreatment. Chi-Squared Automatic Interaction Detector analysis was performed with data from 592 youth from the Longitudinal Studies of Child Abuse and Neglect to identify the optimal combination of age 14 predictors of past-year arrest at age 16. Results extended previous research, which has identified being male, having more conduct disorder symptoms, suspension from school, perceived school importance, witnessing family violence, and having a jailed family member as key risk and protective factors for arrest by identifying important interactions among these risk factors. These interactions differentiate youth at the greatest risk of arrest, which, in this sample, were males with greater than two symptoms of conduct disorder who witnessed family violence. These findings suggest that longitudinal and multi-informant data could inform the refinement of actuarial risk assessments for juvenile arrest.

The development of violence from age 8 to 61

The main aim of this study is to investigate the development of violence from childhood to adulthood. In the Cambridge Study in Delinquent Development (CSDD), 411 London males have been followed up from age 8 to 48 in interviews, and from age 10 to 61 in criminal records; 19% were convicted for violence. There was a surprising amount of violence committed at older ages (40-61). The number of violence convictions was similar at ages 10-20, 21-39, and 40-61. There was considerable continuity in violent offending from ages 10-20 to 40-61. There was also continuity in self-reported violence from ages 15-18 to 43-48, and violence convictions were related to self-reported violence at all ages. The most important childhood risk factors for violence convictions were high daring or risk-taking, low verbal intelligence, a disrupted family, harsh parental discipline, high hyperactivity, and large family size. The extent to which these risk factors predicted violence at ages 40-61 was noteworthy. The "integrated cognitive antisocial potential (ICAP)" theory was proposed to explain the development of violence, and methods of preventing violence, targeting childhood risk factors, were reviewed.

Improved Educational Achievement as a Path to Desistance

In this article we present a summary of the literature on the associations between learning difficulties/disabilities and juvenile delinquency. This literature is almost a hundred years old, but, although reportedly demonstrating the low academic achievement-delinquency connection, contains numerous unanswered questions regarding the frequency, strength, direction, stability, and causality of these associations. We then use this literature to contextualize the research taking place at the Houston Learning Disabilities (LD) Hub, a member of the LD Centers and Hubs Network, supported by National Institute of Child Health and Human Development (NICHD). In doing so, we present our previous studies and our current research. We conclude by discussing a number of shortcomings in the literature, some-but far from all-of which we hope to address in our ongoing work.

The Hidden Matrix: Perspectives of Youth and Their Parents on Immigration and Youth Delinquent Behavior

Immigrant youth delinquency may be associated with developmental, familial, social, and immigration-specific factors; however, scarce studies have examined the perspectives of both parents and their children as to the reasons for involvement in delinquent behavior. This study examines the extent to which immigration-related stressors may be associated with delinquent behavior of immigrant adolescents from the Former Soviet Union in Israel, from the perspectives of both young people and their parents. In-depth interviews with 10 male delinquent immigrant mid-late adolescents, aged 16 to 21 years, and their parents (eight mothers and two fathers) were conducted ( N = 20). Phenomenological analysis highlighted the immigration experience as a hidden matrix within which dynamics associated with delinquency evolved. These dynamics involved situational factors (age, financial hardships, and social norms related to child-rearing), social factors (peer pressure and wish to be socially accepted), familial factors (stress experienced by the family, parental unavailability, and insufficient parental capabilities), and personality factors (sensation-seeking, desire for self-direction, emotion dysregulation, weak character, and inborn inclination to problematic behavior). While few participants directly address the immigration process, it can be considered the backdrop or matrix within which these factors are evolving. Implications for prevention on personal, familial, and society levels are discussed.

Early adolescent aggression predicts antisocial personality disorder in young adults: a population-based study

Modestly prevalent in the general population (~ 4%), but highly prevalent in prison populations (> 40%), the diagnosis of antisocial personality disorder (ASPD) involves aggression as one of several possible criteria. Using multiple informants, we aimed to determine if general aggression, as well as direct and indirect subtypes, assessed in early adolescence (ages 12, 14) predict young adulthood ASPD in a population-based sample. Using data from a Finnish population-based longitudinal twin cohort study with psychiatric interviews available at age 22 (N = 1347), we obtained DSM-IV-based ASPD diagnoses. Aggression measures from ages 12 (parental and teacher ratings) and 14 (teacher, self, and co-twin ratings) were used to calculate odds ratios (OR) of ASPD from logistic regression models and the area under the curve (AUC) from receiver operating characteristic curve analysis. Analyses were adjusted for sex, age, and family structure. All informants' aggression ratings were significant (p < 0.05) predictors of ASPD (OR range 1.3-1.8; AUC range 0.65-0.72). Correlations between informants ranged from 0.13 to 0.33. Models including two or more aggression ratings, particularly age 14 teacher and self ratings, more accurately predicted ASPD (AUC: 0.80; 95% confidence interval 0.73-0.87). Direct aggression rated by all informants significantly predicted ASPD (OR range 1.4-1.9), whereas only self-rated indirect aggression was significantly associated with ASPD (OR = 1.4). Across different informants, general and direct aggression at ages 12 and 14 predicted ASPD in a population-based sample. Psychiatric, social, and parenting interventions for ASPD prevention should focus on children and adolescents with high aggression levels, with an aim to gather information from multiple informants.

The influence of parents and schools on developmental trajectories of antisocial behaviors in Caucasian and African American youths

African American youths are overrepresented in the American juvenile justice system relative to Caucasians. Yet, research on antisocial behaviors (ASB) has focused on predominantly Caucasian populations. Furthermore, relatively little is known about how environmental factors, such as supportive parenting (e.g., how close adolescents feel to their parent) and school connectedness (e.g., how supported adolescents feel at school), affect trajectories of ASB in Caucasians versus African Americans. This study mapped developmental trajectories of ASB in Caucasians (n = 10,764) and African Americans (n = 4,091) separately, using four waves of data from the National Longitudinal Study of Adolescent to Adult Health. We then examined supportive parenting and school connectedness on the trajectories of ASB. Four trajectories of ASB were identified for both Caucasians and African Americans: negligible, adolescence-peaked, low-persistence, and high-persistence ASB, although prevalence rates differed by racial-ethnic status. Supportive parenting reduced the risk of membership into the adolescence-peaked trajectory for both Caucasians and African Americans. However, school connectedness was less protective for African Americans than for Caucasians because it only predicted a lower risk of adolescence-peaked membership for African Americans. Findings may reflect the complex social dynamics between race and schools in the development of ASB.

Low resting heart rate, sensation seeking and the course of antisocial behaviour across adolescence and young adulthood

BACKGROUND

Low resting heart rate (RHR) is a consistent biological correlate of antisocial behaviour (ASB), however potential mechanisms have been largely unexplored. We hypothesise that lower RHR will be associated with higher ASB levels in mid-adolescence and persistence into adulthood, and that these associations will be explained, in part, by sensation seeking and callous-unemotional traits.

METHODS

ASB was assessed repeatedly with young people from ages 15 to 21 years in a population-based birth cohort (ALSPAC). A longitudinal trajectory was derived and showed ASB decreasing across adolescence before stabilising in early adulthood. RHR was recorded at age 12 years, and mediators were assessed at age 14 years.

RESULTS

After adjusting for socio-demographic confounders, there was evidence for a total effect of RHR on ASB levels in mid-adolescence [b(95% CI) = -0.08 (-0.14 to -0.02)], reflecting 0.08 more types of antisocial activity in the last year per 10 fewer heart beats per minute. This effect was almost entirely explained through sensation seeking [b(95% CI) = -0.06 (-0.08 to -0.04)]. After additionally adjusting for child and parent-related confounders, all effects weakened; however, there was still evidence of an indirect effect of RHR, via sensation seeking, on ASB levels in mid-adolescence [b(95% CI) = -0.01 (-0.03 to -0.003)]. There was no evidence for a total effect of RHR on ASB levels in early adulthood, and weak evidence of an indirect effect, via sensation seeking [b(95% CI) = -0.01 (-0.01 to -0.00)].

CONCLUSIONS

Lower RHR in childhood was associated with higher ASB levels in mid-adolescence, indirectly via sensation seeking.

Strengthening mental health and research training in Sub-Saharan Africa (SMART Africa): Uganda study protocol

BACKGROUND

Children in Sub-Saharan Africa (SSA) comprise half of the total regional population, yet existing mental health services are severely under-equipped to meet their needs. Although effective interventions for the treatment of disruptive behavioral disorders (DBDs) in youth have been tested in high-poverty and high-stress communities in developed countries, and are relevant for widespread dissemination in low- and middle-income countries (LMICs), most of these evidence-based practices (EBPs) have not been utilized in SSA, a region heavily impacted by poverty, diseases including HIV/AIDS, and violence. Thus, this paper presents a protocol for a scale-up longitudinal experimental study that uses a mixed-methods, hybrid type II, effectiveness implementation design to test the effectiveness of an EBP, called Multiple Family Group (MFG) aimed at improving child behavioral challenges in Uganda while concurrently examining the multi-level factors that influence uptake, implementation, sustainment, and youth outcomes.

METHODS

The MFG intervention will be implemented and tested via a longitudinal experimental study conducted across 30 public primary schools located in both semi-urban and rural communities. The schools will be randomly assigned to three study conditions (n = 10 per study condition): (1) MFG delivered by trained family peers; (2) MFG delivered by community health workers; or; (3) comparison: usual care comprising mental health care support materials, bolstered with school support materials. A total of 3000 children (ages 8 to 13 years; grades 2 to 7) and their caregivers (N = 3000 dyads); 60 parent peers, and 60 community health workers will be recruited. Each study condition will comprise of 1000 child-caregiver dyads. Data will be collected at baseline, 8 and 16 weeks, and 6-month follow-up.

DISCUSSION

This project is the first to test the effectiveness of the MFG intervention while concurrently examining multi-level factors that influence overall implementation of a family-based intervention provided in schools and aimed at reaching the large child population with mental health service needs in Uganda. Moreover, the study draws upon an EBP that has already been tested for delivery by parent peers and community facilitators, and hence will take advantage of the advancing science behind task-shifting. If successful, the project has great potential to address global child mental health needs.

Does Substance Use Exacerbate Escalation along Developmental Pathways of Covert and Overt Externalizing Behaviors among Young Men?

OBJECTIVES

The delinquency Pathways Model proposes that the majority of those who engage in serious delinquent acts have gone through a sequence of externalizing behaviors from less to more serious delinquent behaviors. This study examined whether frequency of alcohol, marijuana, and hard drugs exacerbated escalation through the covert and overt pathways.

METHODS

Data came from the youngest cohort of the Pittsburgh Youth Study (N = 503). The young men were followed from mean age 7 through mean age 20. Sequences of offending were based on ages of onset of covert and overt delinquent behaviors. Survival analyses were conducted to examine the associations of frequency of use with risk for and timing of movement from the lowest to highest level in each pathway.

RESULTS

Frequency of alcohol and marijuana use was related to greater risk of moving from the lowest to highest level in both pathways and hard drug use vs. nonuse was associated with moving from minor aggression to violence.

CONCLUSIONS

Reducing frequency of substance use may interrupt escalation through the covert and overt pathways for young men once they enter the first level.

Money Now, Money Later: Linking Time Discounting and Criminal Convictions in the Cambridge Study in Delinquent Development

Two prominent criminological theories offer time discounting, or the preference for an immediate reward over a later one, as a central part of understanding involvement in criminal activity. Yet, there exist only a few studies investigating this issue, and they are limited in a few respects. The current study extends prior work in this area by using multiple measures of time discounting collected at three different periods of the life course to examine the link to criminal offending into late middle adulthood in the Cambridge Study in Delinquent Development. Results show that greater time discounting is positively related to a higher number of criminal convictions by late middle adulthood, and this effect remains after controlling for early life-course individual and environmental risk in a multivariate framework. Study limitations and implications are also discussed.

Exploring Differences in Criminogenic Risk Factors and Criminal Behavior Between Young Adult Violent Offenders With and Without Mild to Borderline Intellectual Disability

The relation between mild to borderline intellectual disability (MBID) and violent offense behavior was studied among a group of former juvenile delinquents currently in a diversion program for persistent young adult violent offenders from Amsterdam ( N = 146). Offenders were considered MBID if they had received juvenile probation from the local youth care agency specialized in intellectual disability (21%). A file study was used to estimate prevalence rates of criminogenic risk factors. Police data were used to depict recent criminal behavior. Nearly all offenders grew up in large and unstable multi-problem households and had psychosocial problems. More MBID offenders displayed externalizing behavior before the age of 12, were susceptible to peer pressure, and had low social-relational skills. MBID offenders committed more violent property crimes than offenders without MBID. Youth care interventions for MBID offenders should focus on the acquisition of social-relational skills and on the pedagogical skills of parents.

Poverty, social inequality and mental health

The World Health Organization has described poverty as the greatest cause of suffering on earth. This article considers the direct and indirect effects of relative poverty on the development of emotional, behavioural and psychiatric problems, in the context of the growing inequality between rich and poor. The problems of children in particular are reviewed. Targets to reduce inequality have been set both nationally and internationally.

Classification of psychiatric disorders in childhood and adolescence: building castles in the sand?

A classification system can benefit disturbed children enormously by bringing to bear a wealth of knowledge and experience. This can make all the difference between an inadequate consultation and a precise formulation of the nature and extent of a child's difficulties, their cause, the likely outcome and a realistic treatment plan. However, inappropriate application of a diagnostic label that has little validity could do more harm than good, and classification systems can be misused. This paper discusses, with examples, issues particular to childhood and adolescence that diagnostic systems need to address if they are to be useful. It considers different solutions applied by the two most widely used schemes, theInternational Classification of Diseases(ICD–10; World Heath Organization, 1992) and theDiagnostic and Statistical Manual of Mental Disorders(DSM–IV; American Psychiatric Association, 1994). Finally, the types of criteria used to validate categories are discussed.

Relations between Offending, Injury and Illness

The objectives of this study were to determine relations between offending and health, and how illness and injury relate to concurrent offending—whether offending predicts health or vice versa, and whether relations persist after adjustment for childhood predictors of offending. Data collected in the Cambridge Study in Delinquent Development were analysed. This is a prospective longitudinal survey of 411 South London males first recruited at age 8. Information about injuries and illnesses between ages 16 and 18 was set against information on offending and other types of antisocial behaviour.

Males who were injured (especially in assaults) tended to be convicted, to be violent, to have unskilled manual jobs and to be generally antisocial. Respiratory tract illnesses were negatively related to convictions and antisocial behaviour in general. Drug users were significantly likely to be ill. Adult convictions were predicted by childhood troublesome behaviour, daring/hyperactivity, low IQ/attainment, a convicted parent, family disruption/poor supervision and poverty. Assault injuries and respiratory tract illnesses did not predict adult convictions independently of these childhood factors.

It was concluded that injury is one symptom of an antisocial personality that arises in childhood and persists into adulthood. Therefore, measures that lead to a reduction in offending should also lead to a reduction in concurrent injuries. Negative relations between a range of antisocial behaviours and respiratory tract illness deserve further study.

Assessing the interplay between multigenic and environmental influences on adolescent to adult pathways of antisocial behaviors

The current investigation utilized a developmental psychopathology approach to test the hypothesis that multigenic (i.e., dopaminergic and serotonergic genes) and multienvironmental factors interactively contribute to developmental pathways of antisocial behavior (ASB). A sample of 8,834 Caucasian individuals from the National Longitudinal Study of Adolescent to Adult Health (Add Health) were used to (a) examine the developmental pathways of ASB from age 13 to 32 using growth mixture modeling, (b) compute weighted multigenic risk scores (Add Health MRS) for ASB from six well-characterized polymorphisms in dopamine and serotonin genes, and (c) test the interaction between the Add Health MRS and a measures of support (incorporating indicators of both positive and negative support from parents and schools). Four pathways of adolescent to adult ASB emerged from the growth mixture models: low, adolescence-peaked, high decline, and persistent. Add Health MRS predicted the persistent ASB pathway, but not other ASB pathways. Males with high Add Health MRS, but not low MRS, had significantly greater odds of being in the adolescence-peaked pathway relative to the low pathway at low levels of school connectedness. Nonfamilial environmental influences during adolescence may have a cumulative impact on the development of ASB, particularly among males with greater underlying genetic risks.

Early childhood parenting and child impulsivity as precursors to aggression, substance use, and risky sexual behavior in adolescence and early adulthood

The current study utilized a longitudinal design to explore the effect of early child impulsivity and rejecting parenting on the development of problematic behaviors in adolescence and early adulthood. Using a low-income sample of 310 mothers and their sons, we examined the direct and interactive effects of child impulsivity and rejecting parenting at age 2 on aggression and substance use at ages 12, 15, and 22, as well as risky sexual behavior at ages 15 and 22. Results revealed that rejecting parenting at age 2 predicted greater aggression at age 12 and risky sexual behavior at ages 15 and 22. Early impulsivity had few direct effects on later outcomes, with the exception of greater substance use at age 22. Instead, impulsivity emerged as a significant moderator in the link between rejecting parenting and aggression at all three ages and substance use at age 15. Specifically, early rejecting parenting predicted greater aggression and substance use only for children high in impulsivity. Findings highlight the potential for early child and parenting risk factors to have long-term implications for adjustment, with the combination of high impulsivity and rejecting parenting being particularly deleterious for problems of aggression throughout adolescence and into early adulthood.

Effects of Excessive Alcohol Use on Antisocial Behavior Across Adolescence and Early Adulthood

OBJECTIVE

Antisocial behavior (ASB) decreases with age in most of the population; however, excessive alcohol use can inhibit the desistance process. This study investigated whether excessive early drinking might slow a young person's overall pattern of crime desistance compared with that of others ("between-person effects") and whether short-term increases in alcohol consumption might result in short-term increases in ASB ("within-person effects").

METHOD

Frequency of ASB and typical alcohol consumption were assessed repeatedly in young people 15 to 21 years old in a population-based birth cohort (Avon Longitudinal Study of Parents and Children). Longitudinal trajectories showed ASB decreasing and alcohol use increasing across adolescence, which stabilized in adulthood. The parallel growth model was re-parameterized to simultaneously estimate the person-specific (or "between-person") and time-specific (or "within-person") influences of alcohol on ASB.

RESULTS

Typical alcohol consumption by young people 15 years old was positively associated with ASB cross-sectionally and into young adulthood (i.e., there were between-person effects of initial levels of alcohol consumption on initial [b 1.64, standard error 0.21; p < .001] and final [b 0.53, standard error 0.14; p < .001] levels of ASB). Within-person effects also were identified in early adulthood (b 0.06, standard error 0.02; p = .001), showing that when a young person reported consuming more alcohol than normal across the past year, that person also reported engaging in higher than usual levels of ASB.

CONCLUSION

The results are consistent with between- and within-person effects of excessive alcohol use on ASB desistence. Future research should further investigate this relation by investigating pathways into excessive alcohol use and ASB in adolescence.

Gendered Pathways From Child Abuse to Adult Crime Through Internalizing and Externalizing Behaviors in Childhood and Adolescence

Gender differences in externalizing and internalizing pathways from child abuse to adult crime were examined across four waves of an extended longitudinal study ( N = 186 males and 170 females) using multiple-group structural equation modeling. Results show that child abuse was associated with both internalizing and externalizing behaviors in the elementary school years for both males and females. However, gender differences were found such that internalizing behaviors increased the risk of adult crime for females only, and externalizing behaviors increased the risk of adult crime for males only. Internalizing behaviors among males actually lessened the risk of adult crime, and externalizing behaviors were unrelated to adult crime among females. Findings confirm distinct pathways leading from child abuse to later crime for males and females, which is important for prevention and intervention strategies.

The Utility of the HCR-20 in an Australian Sample of Forensic Psychiatric Patients

The Historical Clinical Risk Management-20 (HCR-20) is utilised internationally to assess an individual's risk for violence. Despite being widely administered in Australian correctional and forensic populations, the predictive validity of the HCR-20 instrument has never been explored in Australian settings. This retrospective study investigated the predictive validity of the HCR-20 for an Australian cohort of 136 forensic psychiatric patients. Findings support the relationship between the HCR-20 and violent offending post hospital discharge. The HCR-20 Total, Historical, and Risk Management scales shared moderate to large positive correlations with several reconviction categories.

An integrative theoretical understanding of aggression: a brief exposition

Like other social behaviors, aggressive behavior is always a product of predisposing personal factors and precipitating situational factors. The predisposing factors exert their influence by creating encoded social cognitions including schemas about the world, scripts for social behavior, and normative beliefs about what is appropriate. These social cognitions interact with situational primes to determine behavior. These social cognitions are acquired primarily through observational learning; so youth who are repeatedly exposed to violence will acquire social cognitions promoting aggression that last into adulthood. Thus, violence can be viewed as a contagious disease which can be caught simply through its observation.

Gambling Harm and Crime Careers

Incarcerated populations across the world have been found to be consistently and significantly more vulnerable to problem gambling than general populations in the same countries. In an effort to gain a more specific understanding of this vulnerability the present study applied latent class analysis and criminal career theory to gambling data collected from a sample of English and Scottish, male and female prisoners (N = 1057). Theoretical links between gambling and crime were tested through three hypotheses: (1) that prisoners in the UK would have higher rates of problem gambling behaviour than the national population; (2) that if the link between gambling and crime is coincidental, gambling behaviour would be highly prevalent in an offending population, and (3) if connections between gambling behaviour and offending are co-symptomatic a mediating factor would show a strong association. The first of these was supported, the second was not supported and the third was partially supported. Latent class analysis found six gambling behaviour clusters measured by responses to the Problem Gambling Severity Index, primarily distinguished by loss chasing behaviour. Longitudinal offending data drawn from the Police National Computer database found four criminal career types, distinguished by frequency and persistence over time. A significant association was found between higher level loss chasing and high rate offending in criminal careers suggesting that impulse control may be a mediating factor for both gambling harm and criminal careers.

Gambling, Risk-Taking, and Antisocial Behavior: A Replication Study Supporting the Generality of Deviance

Research suggests that high frequency gambling is a component of the "generality of deviance", which describes the observation that various forms of risky and antisocial behavior tend to co-occur among individuals. Furthermore, risky and antisocial behaviors have been associated with such personality traits as low self-control, and impulsivity, and sensation-seeking. We conducted a replication (and extension) of two previous studies examining whether high frequency gambling is part of the generality of deviance using a large and diverse community sample (n = 328). This study was conducted as a response to calls for more replication studies in the behavioral and psychological sciences (recent systematic efforts suggest that a significant proportion of psychology studies do not replicate). The results of the present study largely replicate those previously found, and in many cases, we observed stronger associations among measures of gambling, risk-taking, and antisocial behavior in this diverse sample. Together, this study provides evidence for the generality of deviance inclusive of gambling (and, some evidence for the replicability of research relating to gambling and individual differences).

Offenders With Antisocial Personality Disorder Display More Impairments in Mentalizing

This study was designed to test the hypothesis that individuals with antisocial, particularly violent, histories of offending behavior have specific problems in social cognition, notably in relation to accurately envisioning mental states. Eighty-three male offenders on community license, 65% of whom met the threshold for antisocial personality disorder (ASPD), completed a battery of computerized mentalizing tests requiring perspective taking (Perspectives Taking Test), mental state recognition from facial expression (Reading the Mind in the Eyes Test), and identification of mental states in the context of social interaction (Movie for the Assessment of Social Cognition). The results were compared with a partially matched sample of 42 nonoffending controls. The offender group showed impaired mentalizing on all of the tasks when compared with the control group for this study when controlling for demographic and clinical variables, and the offending group performed poorly in comparisons with participants in published studies, suggesting that limited capacity to mentalize may be part of the picture presented by individuals with histories of offending behavior. Offenders with ASPD demonstrated greater difficulty with mentalizing than non-ASPD offenders. Mentalization subscales were able to predict offender status and those with ASPD, indicating that specific impairments in perspective taking, social cognition, and social sensitivity, as well as tendencies toward hypomentalizing and nonmentalizing, are more marked in individuals who meet criteria for a diagnosis of ASPD. Awareness of these deficits may be helpful to professionals working with offenders, and specifically addressing these deficits may be a productive aspect of therapy for this "hard to reach" clinical group.

Labeling and intergenerational transmission of crime: The interaction between criminal justice intervention and a convicted parent

Labeling theory suggests that criminal justice interventions amplify offending behavior. Theories of intergenerational transmission suggest why children of convicted parents have a higher risk of offending. This paper combines these two perspectives and investigates whether labeling effects might be stronger for children of convicted parents. We first investigated labeling effects within the individual: we examined the impact of a conviction between ages 19–26 on self-reported offending behavior between 27–32 while controlling for self-reported behavior between 15–18. Our results show that a conviction predicted someone’s later self-reported offending behavior, even when previous offending behavior was taken into account. Second, we investigated whether having a convicted parent influenced this association. When we added this interaction to the analysis, a labeling effect was only visible among people with convicted parents. This supports the idea of cumulative disadvantage: Labeling seems stronger for people who are already in a disadvantaged situation having a convicted parent.

Assessing the Role of Context on the Relationship Between Adolescent Marijuana Use and Property Crimes in Mexico

BACKGROUND

A limited amount of research has been conducted on the association between marijuana use and adolescent crime in developing countries such as Mexico, where crime rates are high and marijuana use is increasing.

OBJECTIVES

To examine the association between the frequency of marijuana use and the likelihood of committing of a property crime, and to identify contextual factors explaining individual differences in the likelihood of committing a property crime.

METHODS

The contribution of marijuana use to property crimes was examined based on two nationwide probabilistic surveys of public high school students, using a multilevel mixed effects logistic regression model.

RESULTS

Marijuana use significantly increased the odds of committing a property crime. Differences between schools were observed in the random effects of marijuana use, suggesting that the likelihood of committing a property crime was differentially affected by contextual factors. In addition, students who were victims of bullying by peers and who had parents that abused alcohol had higher odds of committing a property crime. Perceived disorder in students' schools and neighborhoods also increased students' odds of reporting that they had committed a property crime.

CONCLUSIONS

The importance of the effect of school context on the relationship between marijuana use and the commission of a property crime among Mexican public high school students seemed to increase over time. However, these results may also be due to changes in sampling designs over time.
