CBT-Enhanced Emotion Regulation as a Mechanism of Improvement for Childhood Irritability.

Research supports the clinical importance of childhood irritability, as well as its developmental implications for later anxiety and depression. Appropriate treatment may prevent this progression; however, little evidence exists to guide clinician decision making regarding treatment for chronic irritability symptoms. Given the empirical support for irritability as a dimension of oppositional defiant disorder (ODD), behavioral interventions that improve ODD symptoms, especially through emotion regulation training, are strong candidates for identifying effective treatment strategies for irritability. Data from a randomized controlled effectiveness trial were used to assess hypotheses regarding irritability. The Stop Now and Plan (SNAP) Program was developed for preadolescent youths demonstrating clinically high rates of conduct problems. Participants (252 boys, ages 6-11) were assigned to participate in either SNAP or standard services; data were collected at 4 time points over 15 months. Although lower irritability scores over time were seen for the SNAP group compared to standard services, the main effect for treatment was small and did not reach statistical significance. However, a significant indirect effect of SNAP treatment on irritability via improved emotion regulation skills was found; improved emotion regulation skills were associated with significant and substantial reductions in irritability. Specific effects of SNAP for the improvement of emotion regulation skills function as a mechanism for subsequent reductions in irritability, supporting the distinction between emotion regulation and irritability symptoms. Enhancing increased emotion regulation skills within existing evidence-based interventions for children with ODD should provide a strong foundation for treatments to target irritability symptoms.

Interpersonal Callousness from Childhood to Adolescence: Developmental Trajectories and Early Risk Factors.

Youth with a callous interpersonal style, consistent with features of adult psychopathy (e.g., lack of guilt, deceitful), are at risk for exhibiting severe and protracted antisocial behaviors. However, no studies have examined changes that occur in interpersonal callousness (IC) from childhood to adolescence, and little is known about the influence of early child, social, and contextual factors on trajectories of IC. The current study examined distinct patterns of IC across childhood and adolescence and associations with early risk factors. Participants were an at-risk sample of 503 boys (56% African American) assessed annually from around ages 7-15. Analyses examined child (anger dysregulation, fearfulness), social (peer, family, maltreatment), and contextual (psychosocial adversity) factors associated with teacher-reported IC trajectories across childhood and adolescence. Using latent class growth analysis, five trajectories of IC were identified (early-onset chronic, childhood-limited, adolescent-onset, moderate, low). Approximately 10% of boys followed an early-onset chronic trajectory, and a roughly equal percent of youth followed childhood-limited trajectory (10%) or an adolescent-onset trajectory (12%) of IC across development. Specifically, half of the boys with high IC in childhood did not continue to exhibit significant levels of these features into adolescence, whereas an equal proportion of youth with low IC in childhood demonstrated increasing levels during the transition to adolescence. Boys in the early-onset chronic group were characterized by the most risk factors and were differentiated from those with childhood-limited and adolescent-onset IC only by higher conduct problems, fearlessness, and emotional abuse/neglect. Findings are discussed in terms of developmental models of IC and several avenues for early targeted interventions.

Systematic review of early risk factors for life-course-persistent, adolescence-limited, and late-onset offenders in prospective longitudinal studies.

This paper builds on our previous systematic review of prospective longitudinal studies and examines the early risk factors associated with life-course persistent offending (LCP), adolescence-limited (AL) and late-onset (LO) offending. Out of the 55 prospective longitudinal studies which theoretically could possess the relevant information, only four provided information about risk factors associated with the different offending types. An additional three provided data so that relevant analyses could be conducted. The results suggested that there was little evidence that specific early risk factors were associated with specific offending types. There was also limited evidence that specific risk factors predicted specific offending types when criminal career duration was included in the definitions of LCP, AL, and LO offending. However, LCP offenders tended to have a greater number of risk factors, and the magnitude of these was somewhat greater than for AL offenders, who in turn tended to have more risk factors (and of a greater magnitude) than LO offenders. LCP and AL offenders may differ more in degree (in the number and magnitude of risk factors) than in kind (in the specific risk factors that are predictive). Importantly, as the potential criminal career duration was increased in defining the offending types, those with longer careers tended to have more risk factors, but, LCP and AL offenders were not predicted by different risk factors. Much more research is needed on risk factors for offending types defined according to criminal career durations.

Cognitive impulsivity and the development of delinquency from late childhood to early adulthood: Moderating effects of parenting behavior and peer relationships.

Cognitive impulsivity may increase children's risk of developing delinquent behavior. However, the influence of cognitive impulsivity may depend on social environmental risk factors. This study examined the moderating effect of late childhood parenting behaviors and peer relations on the influence of children's cognitive impulsivity on delinquency development across adolescence and early adulthood, while taking possible interactions with intelligence also into account. Delinquent behavior of 412 boys from the Pittsburgh Youth Study was measured annually from ages 13 to 29 years with official arrest records. Cognitive impulsivity (neurocognitive test scores) and intelligence were assessed at age 12-13. Parenting behaviors (persistence of discipline, positive reinforcement, and parental knowledge), peer delinquency, and peer conventional activities were assessed between ages 10 and 13 years. Results showed that, while controlling for intelligence, the influence of youths' cognitive impulsivity on delinquency depended on their parents' behaviors. An interaction was found among cognitive impulsivity, intelligence, and peer delinquency, but instead of cognitive impulsivity, the effect of intelligence on delinquency was particularly moderated. Overall, findings suggest that when there was moderation, high cognitive impulsivity and low intelligence were associated with an increased probability for engaging in delinquency predominantly among boys in a good social environment, but not in a poor social environment.

Dating violence in teenage girls: parental emotion regulation and racial differences.

BACKGROUND: Teen dating violence (TDV) is a common phenomenon of great public concern. TDV may lead to severe long-term consequences for victims and offenders, and even more so for females than for males. AIM: The aim of this paper is to investigate possible underlying factors for involvement in TDV either as a perpetrator or a victim. Social learning theory is commonly used to explain internalisation of parents' behaviour on children's behavioural expressions, but less so on parents' emotion regulation as a direct link to later TDV. METHOD: We used longitudinal data from the Pittsburgh Girls Study (N = 2450) to investigate if and how parents' positive and negative emotion regulation is related to TDV, controlling for early aggression and race. RESULTS: Results show a moderately strong association between parents' negative emotion regulation and their daughters' involvement in serious dating violence. We also found that many more African American girls were involved in TDV compared to Caucasian girls, both as a perpetrator and victim. CONCLUSIONS AND PRACTICAL IMPLICATIONS: We discuss directions for future research focusing on emotion regulation and dating violence. Copyright © 2016 John Wiley & Sons, Ltd.

Why is young maternal age at first childbirth a risk factor for persistent delinquency in their male offspring? Examining the role of family and parenting factors.

BACKGROUND: Children born to mothers who were younger than average at their first childbirth are at increased risk for future persistent delinquent behaviour, but explanations for this remain unclear. AIMS: Our aim was to identify possible family and parenting variables that may help explain this relationship. We hypothesised that parental stress, large number of children in the home, low socioeconomic status (including neighbourhood problems) and poor parenting would account for the link between early first motherhood and their offspring's delinquency. METHODS: Four hundred and sixty-two boys were selected from the Pittsburgh Youth Study, a longitudinal study of a random sample of school boys in Pittsburgh, initially assessed half-yearly and then annually from 7 to 19 years of age, using self-reporting and other reporting methods. Indirect effect models were used to test relationships between variables. RESULTS: Higher levels of parental stress, poorer parent-child communication and caring for a larger number of children all mediated the relationship between maternal youth and persistent delinquency by their boys, but only explained about 20% of it. DISCUSSION: At least partial explanations of the relationship between a mother's age at first childbirth and persistent delinquency in her male offspring suggest that future research should test whether early interventions with younger mothers to decrease their sense of stress in parenting and improve their capacity for communication with their child(ren) may help to prevent persistent delinquency in their boys. Programmes designed to help young women make more informed and planned decisions about their pregnancies should also be evaluated. Copyright © 2015 John Wiley & Sons, Ltd.

Criterion validity of the general factor of psychopathology in a prospective study of girls.

BACKGROUND: The best-fitting model of the structure of common psychopathology often includes a general factor on which all dimensions of psychopathology load. Such a general factor would be important if it reflects etiologies and mechanisms shared by all dimensions of psychopathology. Nonetheless, a viable alternative explanation is that the general factor is partly or wholly a result of common method variance or other systematic measurement biases. METHODS: To test this alternative explanation, we extracted general, externalizing, and internalizing factor scores using mother-reported symptoms across 5-11 years of age in confirmatory factor analyses of data from a representative longitudinal study of 2,450 girls. Independent associations between the three psychopathology factor scores and teacher-reported criterion variables were estimated in multiple regression, controlling intelligence, and demographic covariates. RESULTS: The model including the general factor fit significantly better than a correlated two-factor (internalizing/externalizing) model. The general factor was robustly and independently associated with all measures of teacher-reported school functioning concurrently during childhood and prospectively during adolescence. CONCLUSIONS: These findings weaken the hypothesis that the general factor of psychopathology in childhood is solely a measurement artifact and support further research on the substantive meaning of the general factor.

Girls' childhood trajectories of disruptive behavior predict adjustment problems in early adolescence.

BACKGROUND: It is widely recognized that early onset of disruptive behavior is linked to a variety of detrimental outcomes in males, later in life. In contrast, little is known about the association between girls' childhood trajectories of disruptive behavior and adjustment problems in early adolescence. METHODS: This study used nine waves of data from the ongoing Pittsburgh Girls Study. A semiparametric group-based model was used to identify trajectories of disruptive behavior in 1,513 girls from age 6 to 12 years. Adjustment problems were characterized by depression, self-harm, Post Traumatic Stress Disorder (PTSD), substance use, interpersonal aggression, sexual behavior, affiliation with delinquent peers, and academic achievement at ages 13 and 14. RESULTS: Three trajectories of childhood disruptive behavior were identified: low, medium, and high. Girls in the high group were at increased risk for depression, self-harm, PTSD, illegal substance use, interpersonal aggression, early and risky sexual behavior, and lower academic achievement. The likelihood of multiple adjustment problems increased with trajectories reflecting higher levels of disruptive behavior. CONCLUSION: Girls following the high childhood trajectory of disruptive behavior require early intervention programs to prevent multiple, adverse outcomes in adolescence and further escalation in adulthood.

The effectiveness of the Stop Now and Plan (SNAP) program for boys at risk for violence and delinquency.

Among the available treatments for disruptive behavior problems, a need remains for additional service options to reduce antisocial behavior and prevent further development along delinquent and violent pathways. The Stop Now and Plan (SNAP) Program is an intervention for antisocial behavior among boys between 6 and 11. This paper describes a randomized controlled treatment effectiveness study of SNAP versus standard behavioral health services. The treatment program was delivered to youth with aggressive, rule-breaking, or antisocial behavior in excess of clinical criterion levels. Outcomes were measured at 3, 9, and 15 months from baseline. Youth in the SNAP condition showed significantly greater reduction in aggression, conduct problems, and overall externalizing behavior, as well as counts of oppositional defiant disorder and attention deficit hyperactivity disorder symptoms. Additional benefits for SNAP were observed on measures of depression and anxiety. Further analyses indicated that the SNAP program was more effective among those with a higher severity of initial behavioral problems. At 1 year follow-up, treatment benefits for SNAP were maintained on some outcome measures (aggression, ADHD and ODD, depression and anxiety) but not others. Although overall juvenile justice system contact was not significantly different, youth in SNAP had significantly fewer charges against them relative to those standard services. The SNAP Program, when contrasted with standard services alone, was associated with greater, clinically meaningful, reductions in targeted behaviors. It may be particularly effective for youth with more severe behavioral problems and may result in improvements in internalizing problems as well.

The association between childhood maltreatment, mental health problems, and aggression in justice-involved boys.

The link between childhood maltreatment and adolescent aggression is well documented; yet, studies examining potential mechanisms that explain this association are limited. In the present study, we tested the association between childhood maltreatment and adolescent aggression in boys in juvenile justice facilities (N = 767) and examined the contribution of mental health problems to this relationship. Data on childhood maltreatment, mental health problems, and aggression were collected by means of self-report measures and structural equation models were used to test mediation models. We found that mental health problems mediated the link between maltreatment and aggression. Results demonstrated different pathways depending on the type of aggression examined. The association between childhood maltreatment and reactive aggression was fully mediated by a variety of mental health problems and for proactive aggression the association was partially mediated by mental health problems. We also found that reactive and proactive aggression partially mediated the association between maltreatment and mental health problems. These findings suggest that a transactional model may best explain the negative effects of childhood trauma on mental health problems and (in particular reactive) aggression. In addition, our findings add to the existing evidence that reactive and proactive aggression have different etiological pathways.

Developmental Trajectories of Marijuana Use among Men: Examining Linkages with Criminal Behavior and Psychopathic Features into the Mid-30s.

OBJECTIVES: Examine whether young men who chronically use marijuana are at risk for engaging in drug-related and non-drug-related criminal offending and exhibiting psychopathic personality features in their mid-30s. METHODS: Patterns of marijuana use were delineated in a sample of predominately Black and White young men from adolescence to the mid-20s using latent class growth curve analysis. Self-report and official records of criminal offending and psychopathic personality features were assessed in the mid-30s. Analyses controlled for multiple factors indicative of a preexisting antisocial lifestyle and co-occurring use of other substances and tested for moderation by race. RESULTS: Four latent marijuana trajectory groups were identified: chronic high, adolescence-limited, late increasing, and low/nonusers. Relative to low/nonusers, chronic high and late increasing marijuana users exhibited more adult psychopathic features and were more likely to engage in drug-related offending during their mid-30s. Adolescence-limited users were similar to low/nonusers in terms of psychopathic features but were more likely to be arrested for drug-related crimes. No trajectory group differences were found for violence or theft, and the group differences were not moderated by race. CONCLUSIONS: Young men who engage in chronic marijuana use from adolescence into their 20s are at increased risk for exhibiting psychopathic features, dealing drugs, and enduring drug-related legal problems in their mid-30s relative to men who remain abstinent or use infrequently.

Reciprocal effects of parenting and borderline personality disorder symptoms in adolescent girls.

Theories of borderline personality disorder (BPD) postulate that high-risk transactions between caregiver and child are important for the development and maintenance of the disorder. Little empirical evidence exists regarding the reciprocal effects of parenting on the development of BPD symptoms in adolescence. The impact of child and caregiver characteristics on this reciprocal relationship is also unknown. Thus, the current study examines bidirectional effects of parenting, specifically harsh punishment practices and caregiver low warmth, and BPD symptoms in girls aged 14-17 years based on annual, longitudinal data from the Pittsburgh Girls Study (N = 2,451) in the context of child and caregiver characteristics. We examined these associations through the use of autoregressive latent trajectory models to differentiate time-specific variations in BPD symptoms and parenting from the stable processes that steadily influence repeated measures within an individual. The developmental trajectories of BPD symptoms and parenting were moderately associated, suggesting a reciprocal relationship. There was some support for time-specific elevations in BPD symptoms predicting subsequent increases in harsh punishment and caregiver low warmth. There was little support for increases in harsh punishment and caregiver low warmth predicting subsequent elevations in BPD symptoms. Child impulsivity and negative affectivity, and caregiver psychopathology were related to parenting trajectories, while only child characteristics predicted BPD trajectories. The results highlight the stability of the reciprocal associations between parenting and BPD trajectories in adolescent girls and add to our understanding of the longitudinal course of BPD in youth.

Role of test motivation in intelligence testing.

Intelligence tests are widely assumed to measure maximal intellectual performance, and predictive associations between intelligence quotient (IQ) scores and later-life outcomes are typically interpreted as unbiased estimates of the effect of intellectual ability on academic, professional, and social life outcomes. The current investigation critically examines these assumptions and finds evidence against both. First, we examined whether motivation is less than maximal on intelligence tests administered in the context of low-stakes research situations. Specifically, we completed a meta-analysis of random-assignment experiments testing the effects of material incentives on intelligence-test performance on a collective 2,008 participants. Incentives increased IQ scores by an average of 0.64 SD, with larger effects for individuals with lower baseline IQ scores. Second, we tested whether individual differences in motivation during IQ testing can spuriously inflate the predictive validity of intelligence for life outcomes. Trained observers rated test motivation among 251 adolescent boys completing intelligence tests using a 15-min "thin-slice" video sample. IQ score predicted life outcomes, including academic performance in adolescence and criminal convictions, employment, and years of education in early adulthood. After adjusting for the influence of test motivation, however, the predictive validity of intelligence for life outcomes was significantly diminished, particularly for nonacademic outcomes. Collectively, our findings suggest that, under low-stakes research conditions, some individuals try harder than others, and, in this context, test motivation can act as a third-variable confound that inflates estimates of the predictive validity of intelligence for life outcomes.

Trajectories of depression and anxiety symptoms in adolescent girls: a comparison of parallel trajectory approaches.

Longitudinal mixture models have become popular in the literature. However, modest attention has been paid to whether these models provide a better fit to the data than growth models. Here, we compared longitudinal mixture models to growth models in the context of changes in depression and anxiety symptoms in a community sample of girls from age 10 to 17. Model comparisons found that the preferred solution was a 5-class parallel process growth mixture model that differed in the course of depression and anxiety symptoms reflecting both ordering of symptoms and qualitative group differences. Comparisons between classes revealed substantive differences on a number of outcomes using this solution. Findings are discussed in the context of clinical assessment and implementation of growth mixture models.

Scaling up from convictions to self-reported offending.

AIM: The main aims of this article are to estimate the number of offences that are committed for every one that leads to conviction, and to estimate the probability of an offender being convicted. METHOD: In the Pittsburgh Youth Study, 506 boys were followed up from age 13 to age 24 years, in interviews and criminal records. Self-reports and convictions for serious theft, moderate theft, serious violence and moderate violence were compared. RESULTS: On average, 22 offences were self-reported for every conviction. This scaling-up factor increased with age and was the highest for moderate theft and the lowest for serious theft. The probability of a self-reported offender being convicted was 54%. This percentage increased with the frequency and seriousness of offending and was always higher for African American boys than for Caucasian boys. These race differences probably reflected differences in exposure to risk factors. CONCLUSIONS: More research is needed on scaling-up factors, on frequent and serious offenders who are not convicted, on self-reported non-offenders who are convicted and on why African American boys are more likely than Caucasian boys to be convicted.

Invited address: Street killings: prediction of homicide offenders and their victims.

The article reports on childhood predictors (explanatory, behavioral and offenses) to predict homicide offenders in the longitudinal Pittsburgh Youth Study, and compares these predictors with predictors of homicide victims in the same study. This forms the basis for formulating antecedents that are shared between homicide offenders and homicide victims at a young age (ages 7­11) and antecedents that are not shared or are unique for each. Implications of the research are highlighted for early intervention and for interventions with high-risk offenders.

Understanding desisting and persisting forms of delinquency: the unique contributions of disruptive behavior disorders and interpersonal callousness.

BACKGROUND: While associations between conduct disorder (CD), oppositional defiant disorder (ODD), attention deficit hyperactivity disorder (ADHD), and interpersonal callousness (IC) symptoms and delinquency onset are well established, less is known about whether these characteristics differentiate desisting and persisting delinquency. The current study examined whether childhood and adolescent CD, ODD, ADHD, and IC symptoms uniquely distinguished boys who exhibited persisting versus desisting delinquency from adolescence into adulthood. METHODS: Participants were 503 boys (57% African American) repeatedly assessed from ages 7 to 25. Associations between childhood and adolescent CD, ODD, ADHD, and IC symptoms and desisting and persisting delinquency were examined independently and after controlling for their co-occurrence and multiple covariates. RESULTS: Conduct disorder and IC symptoms in childhood and adolescence were higher among boys whose delinquency persisted into adulthood relative to those boys whose delinquency desisted across time. After controlling for the overlap between symptoms of ADHD, ODD, CD and IC, only adolescent CD and IC symptoms emerged as unique predictors of the differentiation between persisters and desisters. Moreover, adolescent CD and IC symptoms continued to contribute unique variance even after childhood levels of these characteristics were accounted for. CONCLUSIONS: Boys with elevated levels of CD and IC symptoms in childhood and adolescence are at risk for exhibiting a pattern of delinquency that persists from adolescence into adulthood. Intervention efforts designed to prevent chronic delinquency should target youth with co-occurring CD and IC symptoms in childhood and adolescence.

Parent-child relationships of boys in different offending trajectories: a developmental perspective.

BACKGROUND: This study tested the theoretical assumption that transformations of parent-child relationships in late childhood and adolescence would differ for boys following different offending trajectories. METHODS: Using longitudinal multiinformant data of 503 boys (ages 7-19), we conducted Growth Mixture Modeling to extract offending trajectories. Developmental changes in child reports of parent-child joint activities and relationship quality were examined using Latent Growth Curves. RESULTS: Five offending trajectories were found: non-offenders, moderate childhood offenders, adolescent-limited offenders, serious childhood offenders, and serious persistent offenders. Non-offenders reported high and stable levels of relationship quality between age 10 and 16. Adolescent-limited offenders reported a similarly high relationship quality as non-offenders at ages 7 and 10, but a lower and decreasing relationship quality in adolescence. Compared with non-offenders, serious persistent offenders reported poorer parent-child relationship quality at all ages, and a decreasing relationship quality in adolescence. Serious persistent offenders and adolescent-limited offenders reported similar levels and changes in parent-child relationship quality in adolescence. Although serious persistent offenders reported fewer joint activities at age 10 and 13 than non-offenders, a similar linear decrease in joint activities in early to middle adolescence was found for boys in each trajectory. CONCLUSION: Developmental changes in parent-child relationship quality differ for different types of offenders. This finding has scientific and practical implications.

Developmental Patterns of Alcohol Use in Relation to Persistence and Desistance of Serious Violent Offending among African American and Caucasian Young Men.

This study examined the association of alcohol use with persistence and desistance of serious violent offending among African American and Caucasian young men from adolescence into emerging adulthood. Five violence groups were defined: nonviolent, late-onsetters, desisters, persisters, and one-time offenders. We examined alcohol use trajectories for these groups from ages 12 through 24/25 using a four-piecewise linear growth model (ages 12-14, 14-18, 18-21, and 21-24/25). The persisters and desisters reported the highest levels of drinking at age 13. From ages 14 through 18, however, the late-onsetters showed a higher rate of increase in drinking, compared to the persisters and desisters. Starting from age 18, the desisters' drinking trajectory started to resemble that of the nonviolent group, who showed the highest rate of increase in drinking during emerging adulthood. By age 24/25 the persisters could not be distinguished from the late-onsetters; but were lower than the nonviolent and one-timer groups in terms of their drinking. At age 24/25, the desisters were not significantly different from the other violence groups, although they appeared most similar to the nonviolent and one-timer groups. There was no evidence that the association between drinking and violence differed for African Americans and Caucasians. The findings suggest that yearly changes in alcohol use could provide important clues for preventing violent offending.

Exploring the intersection of neighborhood racial and economic composition and individual race on substance use among male adolescents.

This article examines how Blacks and Whites living in neighborhoods with divergent racial and income profiles differed in early onset (by age 14 years) and adolescent lifetime prevalence (by age 18 years) of substance use, with longitudinal data from 473 high-risk boys (58% Black). A latent profile analysis identified four neighborhood classes: Black, lower-income; racially mixed, middle-income; White, middle-income; and White, upper-income. Bivariate analyses showed that Blacks living in racially mixed, middle-income neighborhoods reported the lowest rates of tobacco and marijuana use. Whites living in White, upper-income neighborhoods reported higher substance use prevalence, particularly marijuana. Findings suggest that substance use prevention efforts are critical for Whites in upper-income communities.
