Maltreatment and Parent-Child Attachment as Predictors of Dating Violence and Risky Sexual Behaviour Among High-Risk Teens.

A history of maltreatment can increase risk for dating violence (DV) and risky sexual behaviour (RSB) among adolescents. Secure parent-child attachment may reduce this risk, yet few studies have examined this as a protective factor. This study differentiated developmentally appropriate, exploratory sexual behaviours from RSB and examined whether maltreatment experiences and parent-child attachment in adolescence predicted DV and RSB reported five years later in a high-risk sample. Participants were 179 adolescents (46% girls; M age = 15.34, range = 12-18 years) at risk for aggressive and antisocial behaviour. Adolescents reported their maltreatment histories and attachment to their parents at Time 1; five years later, at Time 2, they reported their experiences with DV perpetration and victimization and engagement in RSB. Both bivariate correlations and structural analyses demonstrated that maltreatment was associated with DV perpetration and victimization but not RSB, and attachment avoidance was associated with fewer RSB but not DV. Attachment anxiety was associated with physical DV perpetration and greater condom use, but only at the correlational level; attachment anxiety was not associated with DV or RSB in the structural model. There were no significant interaction effects. Findings highlight the importance of considering key developmental factors such as maltreatment and parent-child attachment in understanding adolescent risk for DV and RSB, and may inform future research that accounts for contextual factors such as motivation for violence perpetration and contraceptive use with multiple and/or casual sex partners.

Impulsivity profiles across five harmonized longitudinal childhood preventive interventions and associations with adult outcomes.

This study aimed to parse between-person heterogeneity in growth of impulsivity across childhood and adolescence among participants enrolled in five childhood preventive intervention trials targeting conduct problems. In addition, we aimed to test profile membership in relation to adult psychopathologies. Measurement items representing impulsive behavior across grades 2, 4, 5, 7, 8, and 10, and aggression, substance use, suicidal ideation/attempts, and anxiety/depression in adulthood were integrated from the five trials (N = 4,975). We applied latent class growth analysis to this sample, as well as samples separated into nonintervention (n = 2,492) and intervention (n = 2,483) participants. Across all samples, profiles were characterized by high, moderate, low, and low-increasing impulsive levels. Regarding adult outcomes, in all samples, the high, moderate, and low profiles endorsed greater levels of aggression compared to the low-increasing profile. There were nuanced differences across samples and profiles on suicidal ideation/attempts and anxiety/depression. Across samples, there were no significant differences between profiles on substance use. Overall, our study helps to inform understanding of the developmental course and prognosis of impulsivity, as well as adding to collaborative efforts linking data across multiple studies to better inform understanding of developmental processes.

Callous-Unemotional Traits in Adolescents' Daily Life: Associations with Affect and Emotional and Conduct Problems.

Intensive longitudinal methods (e.g., daily diary) inform understanding of dynamic processes by parsing within-person state-like fluctuations from stable between-person trait-like differences. In this exploratory study, we investigated whether self-reported callous-unemotional (CU) traits (callousness, uncaring) demonstrated daily fluctuations, as well as whether daily CU traits were associated with multiple forms of daily emotional and behavioral functioning. A sample of 99 adolescents (55.8% female; Mage = 14.60 years) provided baseline information and completed a naturalistic 30-day diary reporting on CU traits, positive and negative affect, and emotional and conduct problems in their daily lives. Dynamic structural equation modeling revealed that many CU traits items showed within-person autoregressive and cross-lagged links; however, there was substantial between-person variation in within-person fluctuations across items. At the subscale level, cross-day associations were observed between callousness and uncaring, conduct problems and uncaring, positive affect and callousness, negative affect and emotional problems, and emotional problems and negative affect. By harnessing intensive longitudinal data, our findings provide preliminary state-level evidence of CU traits, as well as functional information with regards to CU traits and emotional and behavioral problems in daily life. We consider the implications of our findings in terms of informing future CU traits intensive longitudinal evaluations.

Kindergarten conduct problems are associated with monetized outcomes in adolescence and adulthood.

BACKGROUND: Across several sites in the United States, we examined whether kindergarten conduct problems among mostly population-representative samples of children were associated with increased criminal and related (criminal + lost offender productivity + victim; described as criminal + victim hereafter) costs across adolescence and adulthood, as well as government and medical services costs in adulthood. METHODS: Participants (N = 1,339) were from two multisite longitudinal studies: Fast Track (n = 754) and the Child Development Project (n = 585). Parents and teachers reported on kindergarten conduct problems, administrative and national database records yielded indexes of criminal offending, and participants self-reported their government and medical service use. Outcomes were assigned costs, and significant associations were adjusted for inflation to determine USD 2020 costs. RESULTS: A 1SD increase in kindergarten conduct problems was associated with a $21,934 increase in adolescent criminal + victim costs, a $63,998 increase in adult criminal + victim costs, a $12,753 increase in medical services costs, and a $146,279 increase in total costs. In the male sample, a 1SD increase in kindergarten conduct problems was associated with a $28,530 increase in adolescent criminal + victim costs, a $58,872 increase in adult criminal + victim costs, and a $144,140 increase in total costs. In the female sample, a 1SD increase in kindergarten conduct problems was associated with a $15,481 increase in adolescent criminal + victim costs, a $62,916 increase in adult criminal + victim costs, a $24,105 increase in medical services costs, and a $144,823 increase in total costs. CONCLUSIONS: This investigation provides evidence of the long-term costs associated with early-starting conduct problems, which is important information that can be used by policymakers to support research and programs investing in a strong start for children.

Introduction to the Special Issue: Novel Insights into the Externalizing Psychopathology Spectrum in Childhood and Adolescence from Intensive Longitudinal Data.

Externalizing psychopathology is highly prevalent in children and adolescents. Yet, current understanding of the externalizing psychopathology spectrum is predominantly founded on cross-sectional and conventional longitudinal designs. Compared to these designs, intensive longitudinal data have greater ecological validity and provide insight into within-person fluctuations and short-term developmental dynamics. In this Special Issue, we bring together a selection of 10 innovative and original empirical articles to demonstrate the benefits of intensive longitudinal data for understanding the development of the externalizing psychopathology spectrum during childhood and adolescence, as well as one thoughtful commentary from leaders in the externalizing psychopathology field. In this Introduction to the Special Issue, we describe the articles included in this Special Issue in relation to study designs, timescales, samples, and statistical modeling techniques. We conclude by considering the implications of intensive longitudinal data for informing and enhancing our understanding of externalizing psychopathology with child and adolescent samples, as well as critical future research directions.

Child and Adolescent Psychopathology and Subsequent Harmful Behaviors Associated with Premature Mortality: A Selective Review and Future Directions.

In the United States (U.S.), premature mortality in adulthood from suicide, alcohol-related disease, and substance overdoses has increased steadily over the past two decades. To better understand these trends, it is necessary to first examine the harmful behaviors that often precede these preventable deaths (i.e., suicidal ideation and attempts, and harmful alcohol and substance use). Representing critical developmental periods in which psychopathology is most likely to emerge, childhood and adolescence provide an informative lens through which to investigate susceptibility to harmful behaviors. This article synthesizes current evidence describing these rising U.S. mortality rates and the prevalence rates of harmful behaviors linked to these types of mortality. A brief selective review of longitudinal research on harmful behaviors in relation to the most relevant categories of child and adolescent psychopathology is then provided. Finally, recommendations for future research and implications for prevention are discussed.

Psychosis Symptom Trajectories Across Childhood and Adolescence in Three Longitudinal Studies: An Integrative Data Analysis with Mixture Modeling.

Psychotic-like experiences (PLEs) are common throughout childhood, and the presence of these experiences is a significant risk factor for poor mental health later in development. Given the association of PLEs with a broad number of mental health diagnoses, these experiences serve as an important malleable target for early preventive interventions. However, little is known about these experiences across childhood. While these experiences may be common, longitudinal measurement in non-clinical settings is not. Therefore, in order to explore longitudinal trajectories of PLEs in childhood, we harmonized three school-based randomized control trials with longitudinal follow-up to identify heterogeneity in trajectories of these experiences. In an integrative data analysis (IDA) using growth mixture modeling, we identified three latent trajectory classes. One trajectory class was characterized by persistent PLEs, one was characterized by high initial probabilities but improving across the analytic period, and one was characterized by no reports of PLEs. Compared to the class without PLEs, those in the improving class were more likely to be male and have higher levels of aggressive and disruptive behavior at baseline. In addition to the substantive impact this work has on PLE research, we also discuss the methodological innovation as it relates to IDA. This IDA demonstrates the complexity of pooling data across multiple studies to estimate longitudinal mixture models.

Childhood Experiences of Alternative Care and Callousness/Unemotionality: A Conceptual Model, Scoping Review, and Research Agenda.

Individuals with experiences of alternative care (AC; i.e., out-of-home care and institutional care) are at high risk for various mental health and relational problems stemming from exposure to serious attachment disruptions, loss, and complex trauma. Yet, despite the interpersonal context of their significant adversities, surprisingly there is scant research explicitly focusing on callousness/unemotionality (e.g., lack of guilt, callous disregard for others) in this population. This paper provides the first conceptual model for, and systematic scoping review of, callousness/unemotionality in children and young people with experiences of AC. In a comprehensive search of nine databases, 22 articles involving samples of participants in AC or with histories of AC, were identified for inclusion. The pattern of findings revealed that callous-unemotional and psychopathic traits are elevated in children and young people with AC experiences, and positively associated with AC. Moreover, results showed associations between these traits and various psychosocial correlates, most consistently with externalizing and internalizing problems and attachment-related problems. Only two intervention studies were located, one of which found benefits of training and supporting foster caregivers for reducing callous-unemotional traits. These findings are discussed with respect to gaps in the literature, future research directions, and trauma-informed practice to assess and treat callousness/unemotionality in children and young people with experiences of AC.

Psychometric Evaluation of the Affect Regulation Checklist: Clinical and Community Samples, Parent-Reports and Youth Self-Reports.

The Affect Regulation Checklist (ARC) was designed to capture affect dysregulation, suppression, and reflection. Importantly, affect dysregulation has been established as a transdiagnostic mechanism underpinning many forms of psychopathology. We tested the ARC psychometric properties across clinical and community samples and through both parent-report and youth self-report information. Clinical sample: Participants included parents (n = 814; Mage = 43.86) and their child (n = 608; Mage = 13.98). Community sample: Participants included independent samples of parents (n = 578; Mage = 45.12) and youth (n = 809; Mage = 15.67). Exploratory structural equation modeling supported a three-factor structure across samples and informants. Dysregulation was positively associated with all forms of psychopathology. In general, suppression was positively associated with many forms of psychopathology, and reflection was negatively associated with externalizing problems and positively associated with internalizing problems.

Developmental Precursors of Primary and Secondary Callous-Unemotional Traits in Youth.

There is growing evidence of diverse etiological pathways to the development of callous-unemotional (CU) traits, known as primary and secondary CU variants. The purpose of the present study was to extend previous cross-sectional research and examine theoretical predictors of CU variants prospectively from childhood to adolescence. Participants included high-risk control and normative samples from the Fast Track project (N = 754, male = 58%, Black = 46%). Using structural equation modelling, primary CU traits, identified in early adolescence, were associated with higher levels of childhood emotion regulation and lower levels of prosocial behavior. Secondary CU traits were associated with lower levels of childhood emotion regulation and low parental warmth, but not prosocial behaviour. Neither CU variant was related to harsh parenting. Parental warmth moderated emotion regulation and prosocial behavior on secondary CU traits. Results were not moderated by sex. A greater understanding of theoretical developmental precursors of CU variants may better guide intervention efforts.

Primary and secondary callous-unemotional traits in adolescence are associated with distinct maladaptive and adaptive outcomes in adulthood.

While phenotypically indistinguishable with respect to callousness, individuals with primary and secondary callous-unemotional (CU) traits may show different developmental outcomes. This research predominantly comprised cross-sectional studies of male participants with a focus on maladaptive correlates. Thus, the present study examined whether youth with primary and secondary CU traits identified in Grade 7 reported distinct maladaptive outcomes (internalizing, externalizing, and substance use problems; criminal offenses; and sexual and partner experiences) and adaptive outcomes (health and wellbeing, education, and employment) in adulthood at age 25. We also examined sex differences. Participants included the high-risk control and normative samples from the Fast Track project (N = 754, male = 58%, Black = 46%). Youth with secondary CU traits reported higher levels of adult internalizing and externalizing psychopathology, a greater number of sexual partners and risky sexual behavior, and a greater number of violent offenses, compared with individuals with primary CU traits and those with low CU and anxiety symptoms. Conversely, youth with primary CU traits and low symptoms had higher wellbeing and happiness scores than those with secondary CU traits. Finally, there was differentiation on outcomes between female primary and secondary CU variants and male primary and secondary CU variants.

Predictive Validity of Adolescent Callous-Unemotional Traits and Conduct Problems with Respect to Adult Outcomes: High- and Low-Risk Samples.

Current understanding of the predictive validity of callous-unemotional (CU) traits is limited by (a) the focus on externalizing psychopathology and antisocial behaviors, (b) a lack of long-term prospective longitudinal data, (c) samples comprised of high-risk or low-risk individuals. We tested whether adolescent CU traits and conduct problems were associated with theoretically relevant adult outcomes 12-18 years later. Participants were drawn from two studies: higher-risk Fast Track (FT; n = 754) and lower-risk Child Development Project (CDP; n = 585). FT: conduct problems positively predicted externalizing and internalizing psychopathology and partner violence, and negatively predicted health, wellbeing, and education. Three conduct problems × CU traits interaction effects were also found. CDP: CU traits positively predicted depression and negatively predicted health and education; conduct problems positively predicted externalizing and internalizing psychopathology and substance use, and negatively predicted wellbeing. CU traits did not provide incremental predictive validity for multiple adult outcomes relative to conduct problems.

Intergenerational effects of the Fast Track intervention on the home environment: A randomized control trial.

BACKGROUND: Maladaptive family environments harm child development and are passed across generations. Childhood interventions may break this intergenerational cycle by improving the family environments children form as adults. The present study investigates this hypothesis by examining follow-up data collected 18 years after the end of the childhood Fast Track intervention designed to prevent externalizing problems. METHODS: We examined whether Fast Track assignment from grades 1 to 10 prevented the emergence of maladaptive family environments at age 34. A total of 400 (n = 206 in intervention condition, n = 194 controls) Fast Track participants who were parents at age 34 were surveyed about 11 aspects of their current family environment. The hypotheses and analytic plan were preregistered at https://osf.io/dz9t5 and the Fast Track trial was registered at clinicaltrials.gov (NCT01653535). RESULTS: Multiple group linear regression models revealed that mothers who participated in the Fast Track intervention as children had lower depression symptoms, alcohol problems, drug problems, corporal punishment use, and food insecurity compared to control group mothers. All effects were modest in magnitude. However, for these same mothers, the Fast Track intervention had no effect on cannabis problems, experiences of romantic partner violence, or maternal use of physical aggression or warmth with their children. Additionally, mothers in the Fast Track intervention group reported higher levels of family chaos than those in the control group, but this effect may be a byproduct of the higher number of children per household in the intervention group. No intervention effects were found for fathers who participated in the Fast Track intervention as children. CONCLUSIONS: Childhood assignment to Fast Track has some beneficial effects for girls, but not boys, on the family environments these individuals formed as adults 18 years later.

Predictors of problematic adult alcohol, cannabis, and other substance use: A longitudinal study of two samples.

This study examined whether a key set of adolescent and early adulthood risk factors predicts problematic alcohol, cannabis, and other substance use in established adulthood. Two independent samples from the Child Development Project (CDP; n = 585; 48% girls; 81% White, 17% Black, 2% other race/ethnicity) and Fast Track (FT; n = 463; 45% girls; 52% White, 43% Black, 5% other race/ethnicity) were recruited in childhood and followed through age 34 (CDP) or 32 (FT). Predictors of substance use were assessed in adolescence based on adolescent and parent reports and in early adulthood based on adult self-reports. Adults reported their own problematic substance use in established adulthood. In both samples, more risk factors from adolescence and early adulthood predicted problematic alcohol use in established adulthood (compared to problematic cannabis use and other substance use). Externalizing behaviors and prior substance use in early adulthood were consistent predictors of problematic alcohol and cannabis misuse in established adulthood across samples; other predictors were specific to the sample and type of substance misuse. Prevention efforts might benefit from tailoring to address risk factors for specific substances, but prioritizing prevention of externalizing behaviors holds promise for preventing both alcohol and cannabis misuse in established adulthood.

Externalizing psychopathology from childhood to early adolescence: Psychometric evaluation using latent variable and network modeling.

Applying both latent variable and network frameworks, we conducted a comprehensive psychometric evaluation of the diverse array of symptoms from three externalizing dimensions, including attention problems, aggressive behavior, and delinquency/rule-breaking of the Child Behavior Checklist (Achenbach, 1991) across six time points from childhood to early adolescence. We also examined sex differences. Participants (N = 1,339) were drawn from two multisite longitudinal studies: Fast Track and the Child Development Project. Parents reported on externalizing psychopathology in kindergarten and Grades 1, 2, 4, 5, and 7. Using exploratory structural equation modeling, we found almost uniformly excellent fit across time and samples. However, we also observed multiple cross-loadings and heterogeneity in terms of which symptoms cross-loaded across time points. Alternatively, using network modeling, we observed that symptoms of attention problems and aggressive behavior had stronger connections, relative to delinquency/rule-breaking, across time and samples. Significant differences in overall connectivity were found at early (kindergarten vs. Grade 1, Grade 1 vs. Grade 2) and late (Grade 5 vs. Grade 7) time points for the combined sample and only late time points for the male sample. In addition, the items impulsive and lies or cheats consistently displayed the greatest bridge strength, that is, symptom from one dimension that connects to symptoms from another dimension, across time and samples. Our results illustrate how two methods-latent variable and network modeling-provide important and complementary information on multidimensional constructs. Findings also inform understanding of externalizing psychopathology through childhood to early adolescence by identifying key symptoms, critical transition points, and possible transdiagnostic liabilities.

Examining the Directionality of the Relationship Between Maternal Warmth and Early School-Age Anxiety.

Maternal warmth has been identified as a contributing factor to the development of child anxiety; however, no studies to date have examined observed maternal warmth longitudinally in this relationship. The present study addressed this knowledge gap by examining the simultaneous development of maternal warmth and child anxiety over time (between-person effects using latent growth curve modeling) and the directionality of associations (within-person effects using autoregressive latent trajectory modeling). Participants included 753 mothers and children. Between-person effects indicated that lower initial levels of anxiety were related to greater levels of maternal warmth over time. Within-person effects showed that maternal warmth in grade 1 predicted subsequent decreases in child anxiety in grade 2 (i.e., a parent effect). Present findings demonstrate the importance of maternal warmth in the early school-age years for decreasing subsequent child anxiety.

Patterns and Predictors of Different Youth Responses to Attachment-Based Parent Intervention.

OBJECTIVE: Few studies have evaluated attachment-based parent interventions for pre-teens and teens, and in particular, differential adolescent trajectories of response. This study examined distinct patterns, and multi-level predictors, of intervention response among youth with serious behavioral and mental health problems whose parents participated in Connect, an attachment- and trauma-informed parent program. METHOD: Participants included 682 parents (Mage = 42.83, 86% mothers) and 487 youth (Mage = 13.95, 53% female, 28.1% ethnic minority) enrolled in a community-based evaluation of Connect. Parents and youth reported on youth externalizing and internalizing problems (EXT and INT) at six time points from baseline through 18-months post-intervention. Demographic and youth and family level predictors were assessed at baseline. RESULTS: Growth mixture modeling revealed three distinct trajectory classes in both the parent and youth models based on different patterns of co-occurring EXT and INT and degree of improvement over time. Youth with severe EXT showed the largest and fastest improvement, and, interestingly, were characterized by higher callous-unemotional traits and risk-taking at program entry. Youth with comorbid EXT/INT demonstrated a partial or moderate response to intervention in the parent and youth model, respectively, and were characterized by more attachment anxiety at baseline. Most youth showed relatively moderate/low levels of EXT/INT at baseline which gradually improved. Caregiver strain also predicted trajectory classes. CONCLUSIONS: These results have significance for tailoring and personalizing interventions for high-risk youth and provide new understanding regarding the profiles of subgroups of youth who show different responses to an attachment-based parent intervention.

The comparative and cumulative impact of different forms of violence exposure during childhood and adolescence on long-term adult outcomes.

Violence exposure during childhood and adolescence is associated with a range of negative psychosocial outcomes. Research examining the impact of violence exposure has been limited by the compartmentalization into separate bodies of research (e.g., community violence, domestic violence). There is also a paucity of research examining long-term adult outcomes. Using a large and racially diverse sample (n = 754; male = 58%; Black = 46%), the current longitudinal study aimed to elucidate the comparative and cumulative effect of different types of violence exposure (witnessing vs. victimization) across different locations (home, school, neighborhood) in childhood and adolescence (lifetime through Grade 8) on long-term internalizing, externalizing, and attention problems; substance use; and intimate partner violence in adulthood (age 25). Victimization, but not witnessing violence, predicted all five adult outcomes. Specifically, being victimized at home was associated with the widest range of negative outcomes (internalizing, externalizing, and attention problems), while school victimization was associated with substance use. Further, when youth experienced multiple types of violence across multiple locations (cumulative violence exposure), they experienced a more diverse range of negative outcomes in adulthood (composite score). The current study highlights the stronger effects of violence exposure in more proximal contexts, and how these locations are important for emotional and behavioral development.

Longitudinal Associations between Parental Warmth, Harsh Discipline, Child Emotion Regulation, and ODD Dimensions.

Research has yet to investigate the mediating role of emotion regulation in the relation between parental warmth and harsh discipline with oppositional defiant disorder (ODD). Further, few studies have investigated ODD as both a unitary construct and as three distinct dimensions (anger, defiance, spitefulness). Thus, the present study aimed to investigate child emotion regulation (grade 2) as a mediator of the relation between parental warmth and harsh discipline (kindergarten, grade 1, grade 2) and ODD and its dimensions (grade 3). Participants included the high-risk and normative samples from the Fast Track project (N = 753, male = 58 %, Black = 46 %). Constructs were assessed using observation and parent and teacher reports. Although results demonstrated an absence of indirect effects, emotion regulation was negatively associated with overall ODD and anger and defiance, but not spitefulness. Findings illustrate how increased attention toward the study of ODD as distinct dimensions contributes to our ability to parse out heterogeneity among children with the disorder.

Validation and measurement invariance of the Inventory of Callous-Unemotional Traits in Chinese incarcerated and normative samples.

OBJECTIVE: This study examined the factor structure and psychometric properties of the Inventory of Callous-Unemotional Traits (ICU) in a large sample of incarcerated Chinese male inmates and its measurement invariance with an independent normative sample of Chinese adults. We further investigated the external validity of the ICU in the incarcerated sample. HYPOTHESES: We hypothesized that the short forms of ICU would (a) provide a better model fit and greater internal consistency than the original 24-item ICU, (b) demonstrate measurement invariance between incarcerated and normative samples, and (c) show satisfactory external validity with a variety of external criterion measures. METHOD: A sample of incarcerated Chinese men (N = 498; M age = 33.14) and a normative sample of Chinese adults (N = 168; M age = 23.45, 41% male) self-reported on the ICU. The incarcerated sample also self-reported multiple psychosocial external measures. RESULTS: A short form of the ICU containing 11 items with two correlated factors (Callousness and Uncaring) demonstrated superior model fit, internal consistency, scalar invariance across the two samples, and external validity. CONCLUSIONS: Rigorously and accurately measuring callous-unemotional (CU) traits in Asian populations will enable future research to further understand how these traits develop over the life span, as well as their clinical and forensic implications.
