RESUMEN

Dante Cicchetti's remarkable contributions to the field of developmental psychopathology include the advancement of key principles such as the interplay of typical and atypical development, multifinality and equifinality, the dynamic processes of resilience, and the integration of multiple levels of analysis into developmental theories. In this paper we assert that person-centered data analytic methods are particularly well-suited to advancing these tenets of developmental psychopathology. We illustrate their utility with a brief novel empirical study focused on underlying patterns of childhood neuroendocrine regulation and prospective links with emerging adult functioning. Results indicate that a childhood neuroendocrine profile marked by high diurnal cortisol paired with low diurnal DHEA was uniquely associated with more adaptive functioning in emerging adulthood. We discuss these findings, and person-centered methods more broadly, within the future of developmental psychopathology.

RESUMEN

Person-centered methods represent an important advance in the simultaneous examination of multiple indicators of neuroendocrine functioning and may facilitate a more nuanced understanding of the impact of child maltreatment on hypothalamic-pituitary-adrenal axis dysregulation. The aims of the present study were threefold: (a) identify naturally occurring patterns of diurnal cortisol and dehydroepiandrosterone (DHEA) regulation among a sample of N = 1,258 children with and without histories of maltreatment, (b) investigate which neuroendocrine profiles characterize children with exposure to maltreatment, and (c) examine which profiles are related to adaptive outcomes and symptomatology among children. Cortisol and DHEA were sampled three times per day (9 a.m., 12 p.m., and 4 p.m.) across 5 and 2 days, respectively. Four profiles of cortisol and DHEA regulation were identified. Among females, a pattern marked by high cortisol and low DHEA was associated with more pervasive maltreatment experiences. Furthermore, we found evidence of adaptive interpersonal resilience such that children with maltreatment exposure who evidenced this pattern of high cortisol and low DHEA were viewed as more likeable than maltreated children with other neuroendocrine patterns. Finally, results pointed to higher levels of internalizing symptoms among children who displayed a profile marked by average cortisol and high DHEA.

RESUMEN

Childhood adversity represents a robust risk factor for the development of harmful substance use. Although a range of empirical studies have examined the consequences of multiple forms of adversity (i.e., childhood maltreatment, parental alcohol use disorder [AUD]), there is a dearth of information on the relative effects of each form of adversity when considered simultaneously. The current study utilizes structural equation modeling to investigate three unique and amplifying pathways from parental AUD and maltreatment exposure to offspring alcohol use as emerging adults: (1) childhood externalizing symptomatology, (2) internalizing symptomatology, and (3) affiliation with substance-using peers and siblings. Participants (N = 422) were drawn from a longitudinal follow-up study of emerging adults who participated in a research summer camp program as children. Wave 1 of the study included 674 school-aged children with and without maltreatment histories. Results indicated that chronic maltreatment, over and above the effect of parent AUD, was uniquely associated with greater childhood conduct problems and depressive symptomatology. Mother alcohol dependence was uniquely associated with greater affiliation with substance-using peers and siblings, which in turn predicted greater alcohol use as emerging adults. Results support peer and sibling affiliation as a key mechanism in the intergenerational transmission of substance use between mothers and offspring.

RESUMEN

Research links life stressors, including acute, chronic, and early life stress, to the development of ruminative brooding. However, singular forms of life stress rarely occur in isolation, as adolescents typically encounter stressors that vary on important dimensions (e.g., types, timings, quantities) across development. The current study employs latent profile analysis (LPA) to identify natural clusters of life stress that, over time, may be differently associated with ruminative brooding. Evaluations of episodic, chronic, and early life stress were conducted with community-recruited mid-adolescents (N = 241, Mage = 15.90 years, 53% female) and their parents using the UCLA Life Stress Interview and lifetime adversity portions of the Youth Life Stress Interview. Analyses identified four distinct patterns: low stress, high peer stress, moderate home / family stress, and multifaceted / high school stress. Adolescents in the high peer stress and moderate home / family stress profiles were at highest risk for developing a brooding style over time. Despite high overall levels of stress, teens in the multifaceted / high school stress profile were at not at elevated risk for developing a brooding style. Findings demonstrate the utility of person-centered approaches to identify patterns of stress exposure that heighten risk for brooding over time.

RESUMEN

Experiences of child abuse and neglect are risk factors for youth suicidal thoughts and behaviors. Accordingly, suicide risk may emerge as a developmental process that is heavily influenced by the rearing environment. We argue that a developmental, theoretical framework is needed to guide future research on child maltreatment and youth (i.e., adolescent and emerging adult) suicide, and to subsequently inform suicide prevention efforts. We propose a developmental model that integrates principles of developmental psychopathology and current theories of suicide to explain the association between child maltreatment and youth suicide risk. This model bears significant implications for future research on child maltreatment and youth suicide risk, and for suicide prevention efforts that target youth with child maltreatment experiences.

RESUMEN

Childhood maltreatment is a potent interpersonal trauma associated with dysregulation of emotional processes relevant to the development of psychopathology. The current study identified prospective links between patterns of maltreatment exposures and dimensions of emotion regulation in emerging adulthood. Participants included 427 individuals (48% Male; 75.9% Black, 10.8% White, 7.5% Hispanic, 6% Other) assessed at two waves. At Wave 1, children (10-12 years) from families eligible for public assistance with and without involvement with Child Protective Services took part in a research summer camp. Patterns of child maltreatment subtype and chronicity (based on coded CPS record data) were used to predict Wave 2 (age 18-24 years) profiles of emotion regulation based on self-report, and affective processing assessed via the Affective Go/No-Go task. Results identified associations between task-based affective processing and self-reported emotion regulation profiles. Further, chronic, multi-subtype childhood maltreatment exposure predicted difficulties with aggregated emotion dysregulation. Exposure to neglect with and without other maltreatment subtypes predicted lower sensitivity to affective words. Nuanced results distinguish multiple patterns of emotion regulation in a sample of emerging adults with high exposure to trauma and socioeconomic stress and suggest that maltreatment disrupts emotional development, resulting in difficulties identifying emotions and coping with emotional distress.

RESUMEN

The present study illustrates the utility of latent class analysis, a person-centered data analytic approach, as an innovative method for identifying naturally occurring patterns of polygenic risk, specifically within the dopaminergic system. Moreover, this study tests whether latent classes of polygenic variation moderate the effect of child maltreatment exposure on internalizing symptoms among African ancestry youth. African ancestry youth were selected for this study because youth of color are overrepresented in the child welfare system and because African ancestry individuals are significantly underrepresented in genomics research. Results identified three latent classes of dopaminergic gene variation. Class 1 was marked predominately by homozygous minor alleles, Class 2 was characterized by homozygous major and heterozygous presentations, and Class 3 was marked by heterozygous alleles on the DAT-1 single-nucleotide polymorphisms (SNPs) and a combination of homozygous major and minor alleles on the other SNPs. Results indicated that a greater number of maltreatment subtypes experienced were associated with higher internalizing symptoms only for children with the latent polygenic Class 2 pattern. This latent class was distinctly characterized by more homozygous major or heterozygous allelic presentations along all three DAT-1 SNPs. This significant latent polygenic class by environment interaction was replicated in an independent replication sample. Together, findings suggest that African ancestry children with a pattern of dopaminergic variation characterized by this specific combination of polygenic variation are more vulnerable to developing internalizing symptoms following maltreatment exposure, relative to their peers with other dopamine-related polygenic patterns.

RESUMEN

This study uses a 2-wave, longitudinal design to evaluate mother-child attachment security (child-reported) and emotion regulation capacities (wave 1, age 10-12) as mediators linking childhood maltreatment chronicity and emotion regulation (ER) patterns in emerging adulthood (wave 2; N = 399; 48.1% male; 77.2% Black/African-American, 11.3% White, 7.8% Hispanic, 3.8% other race). Children from families eligible for public assistance with and without maltreatment exposure participated in a summer research camp (wave 1) and were recontacted in emerging adulthood (wave 2). SEM results showed that greater maltreatment chronicity predicted lower childhood attachment security, which in turn predicted membership in ER profiles marked by emotion dysregulation and limited access to ER strategies. Greater attachment security predicted membership in adaptive ER profiles in emerging adulthood. Results suggest that insecure attachment is one process by which childhood maltreatment disrupts adaptive ER across development, whereas greater attachment security in childhood can promote multiple forms of adaptive emotion regulation.

RESUMEN

BACKGROUND: Few studies have investigated the partner's influence on risk factors such as alcohol consumption and depression during pregnancy. Partner substance use and lower relationship satisfaction predict higher maternal alcohol use and depressive symptoms. Because prenatal alcohol use and maternal depression affect infant outcomes, it is imperative to examine how the partner affects these maternal risk factors. The current study examined the effect of a latent construct of partner influence on maternal alcohol use and depressive symptoms, and the effects on infant development of these maternal factors. METHODS: Participants were 246 pregnant women from 2 sites in Western Ukraine from whom longitudinal data were collected as part of a multisite study. In the first trimester, mothers reported on relationship satisfaction, partner substance use, and socioeconomic status (SES). In the third trimester, they reported on alcohol use and depressive symptoms. Infants were assessed using the Bayley Scale of Infant Development (average age = 6.93 months). A latent construct titled partner influence was formed using partner substance use and measures of relationship satisfaction, including the frequency of quarreling, happiness in the relationship, and the ease of talking with the partner. Using structural equation modeling, a model was specified in which partner influence and SES predicted maternal alcohol use and depressive symptoms, which in turn predicted infant neurodevelopmental outcomes. RESULTS: Higher partner influence significantly predicted lower prenatal alcohol use and lower depressive symptoms, controlling for the effect of SES. Higher maternal prenatal alcohol use significantly predicted lower infant mental and psychomotor development. Maternal depressive symptoms did not predict infant development over and above the effect of alcohol use. CONCLUSIONS: Partner influence is an important contributor to prenatal alcohol use and maternal depressive symptoms, over and above the effect of SES. The significant paths from prenatal alcohol exposure to infant neurodevelopmental outcomes underscore the importance of partner influence during pregnancy.

RESUMEN

As a founder of the field of applied developmental psychology, Dr Edward Zigler promoted public policy that translated scientific knowledge into real-world programs to improve the outcomes of high-risk children and families. Many researchers, practitioners, and public policy proponents have sought to carry on his legacy through integration of empirical research, evidence-based prevention and intervention, and advocacy to address a range of challenges facing families with young children. To advance the field of child maltreatment, a multidisciplinary team of investigators from the Universities of Rochester and Minnesota partnered with the Eunice Kennedy Shriver National Institute of Child Health and Human Development to create the Translational Research that Adapts New Science FOR Maltreatment Prevention Center (Transform). Building on state-of-the-art research methodologies and clinical practices, Transform leverages theoretically grounded research and evidence-based interventions to optimize outcomes for individuals across the life span who have experienced, or may be at risk for, maltreatment. Inspired by the work of Dr Zigler, Transform is committed to bridging science and real-world practice. Therefore, in addition to creating new science, Transform's Community Engagement Core provides translational science to a broad audience of investigators, child-serving professionals, and parental and governmental stakeholders. This article describes Transform's purpose, theoretical framework, current activities, and future directions.

RESUMEN

The Building Healthy Children (BHC) home-visiting preventive intervention was designed to provide concrete support and evidence-based intervention to young mothers and their infants who were at heightened risk for child maltreatment and poor developmental outcomes. This paper presents two studies examining the short- and long-term effectiveness of this program at promoting positive parenting and maternal mental health, while preventing child maltreatment and harsh parenting. It also examines the intervention's sustained effect on child symptomatology and self-regulation. At baseline, young mothers and their infants were randomly assigned to receive BHC or Enhanced Community Standard. Families were assessed longitudinally across four time points. Data were also collected from the child's teacher at follow-up. Mothers who received BHC evidenced significant reductions in depressive symptoms at mid-intervention, which was associated with improvements in parenting self-efficacy and stress as well as decreased child internalizing and externalizing symptoms at postintervention. The follow-up study found that BHC mothers exhibited less harsh and inconsistent parenting, and marginally less psychological aggression. BHC children also exhibited less externalizing behavior and self-regulatory difficulties across parent and teacher report. Following the impactful legacy of Dr. Edward Zigler, these findings underline the importance of early, evidence-based prevention to promote well-being in high-risk children and families.

RESUMEN

Teenage childbearing (age 15-19 years) represents a significant public health issue that can generate considerable deleterious, multigenerational consequences for teen-childbearing mothers and their offspring. However, few studies have examined the potential mediating mechanisms that may explain if and how teen childbearing is associated with the development of offspring psychopathology. The current study used a developmental model to test the mediating role of chronic child maltreatment in the relationship between teen childbearing and offspring internalizing symptoms in childhood and emerging adulthood. The study participants were 384 individuals from socioeconomically disadvantaged, ethnically diverse backgrounds, assessed across two longitudinal waves of data (i.e., ages 10-12 and 18-20). The sample included maltreated and nonmaltreated children, all of whom were comparable in terms of family income. Structural equation modeling was conducted to test direct and indirect pathways from teen childbearing to offspring psychopathology. A multigenerational developmental cascade was found such that individuals born to mothers who began their childbearing in adolescence were more likely to experience chronic maltreatment during childhood, which in turn predicted greater internalizing symptoms throughout childhood and emerging adulthood. Using a developmental psychopathology framework, the results are discussed with regard to implications for prevention and early intervention.

RESUMEN

The current study examined the development of toddler attachment and early childhood behavior among children of mothers with a history of childhood maltreatment and current major depressive disorder. Maternal depression, maternal sensitivity, and toddler attachment were assessed as mediators of the association between maternal history of childhood maltreatment and child internalizing and externalizing behavior. Participants were from a low-income, largely racial minority urban sample and included 123 mothers with (n = 69) and without (n = 54) major depressive disorder at baseline and their children assessed at 12, 26, and 36 months old. Findings suggest maternal depression and maternal sensitivity mediated the association between maternal history of childhood maltreatment and disorganized attachment. Maternal depression, but not disorganized attachment, mediated the association between maternal history of childhood maltreatment and child symptomatology. Results suggest that supporting mothers through depression and processing their adverse childhood experiences are critical in fostering positive child development.

RESUMEN

Few conditions epitomize severe and chronic stress to a greater extent than child maltreatment, which can derail development across multiple domains of functioning and throughout the life course. Furthermore, child maltreatment tends to co-occur with other adversities, such as poverty. Many individuals grow up under the stressful conditions of these adversities and exhibit developmental competence. The current study prospectively charted the developmental progression of economically disadvantaged maltreated and nonmaltreated children from childhood to emerging adulthood, and examined patterns of competence across multiple developmental domains of functioning central to the period of emerging adulthood. The study investigated childhood precursors to these patterns of adaptation and maladaptation, as well as the physiological cost of these patterns of adaptation (i.e., C-reactive protein; CRP). Latent class analysis revealed four distinct classes of functioning: multifaceted competence across domains (Multifaceted Competence); (multifaceted maladaptation across domains (Multi-Problem); (c) and two classes with mixed patterns of competence and maladaptation (Externalizing Problems and Work/School Impairment). Maltreated individuals were less likely than nonmaltreated individuals to demonstrate patterns of multifaceted competence and more likely to demonstrate aggregate maladaptation across domains. Additionally, Black men who demonstrated a pattern of multifaceted psychosocial competence also evidenced higher levels of low-grade inflammation (indexed by CRP), suggesting physiological distress was associated with adaptation in the context of stress among these individuals. Findings demonstrate the heterogenous patterns of functioning and diverse developmental outcomes that follow early adversity.

RESUMEN

The impact of maltreatment spreads across many developmental domains and extends across the entire life span. Identifying unidirectional or bidirectional drivers of developmental cascades of the effects of maltreatment experiences is critical to efficiently employing interventions to promote resilient development in maltreated children. This 1-year longitudinal study utilized a multiple-levels approach, investigating "bottom-up" and "top-down" cascades using structural equation modeling between cortisol regulation, externalizing behavior, and peer aggression. Neither a bottom-up model driven by cortisol regulation nor a top-down model driven by peer aggression fit the data well. Instead, lower rates of externalizing behavior at Year 1 most strongly predicted improvements at all levels of analysis (reduced cortisol, externalizing behavior, and peer aggression) at Year 2. These results provide initial indication of a mechanism through which interventions for maltreated children may be most effective and result in the most substantial positive changes across developmental domains.

RESUMEN

Maltreatment during childhood is associated with difficult interpersonal relationships throughout the life course. The aim of the current study was to investigate differential pathways from child maltreatment to emerging adult relationship dysfunction. Specifically, we prospectively tested whether child maltreatment initiates a developmental cascade resulting in coercive negative romantic and friend interactions in emerging adulthood via childhood antisocial tendencies and via childhood relational aggression. Utilizing a longitudinal sample of emerging adult participants (N = 392; mean age = 20 years old) who took part in a summer research camp program as children (mean age = 11 years old), results supported pathways via both childhood antisocial behavior and childhood relational aggression. We found specificity within these pathways such that childhood antisocial behavior was a mediator of child maltreatment effects on emerging adult negative romantic interactions, whereas childhood relational aggression was a mediator of child maltreatment effects on emerging adult negative friend interactions. Taken together, results indicate that children exposed to maltreatment face significant interpersonal challenges in emerging adulthood, within both the friend and the romantic domains, and point to distinct childhood pathways to these negative interactions. Our findings are consistent with Dishion's (2016) theoretical framework for understanding the development of coercion in relationships and highlight the criticality of early intervention with maltreating families.

RESUMEN

Child maltreatment represents a pervasive societal problem. Exposure to maltreatment is predictive of maladjustment across development with enduring negative effects found in adulthood. Compelling evidence suggests that some parents with a history of child abuse and neglect are at elevated risk for the maltreatment of their own children. However, a dearth of research currently exists on mediated mechanisms that may underlie this continuity. Ecological and transactional theories of child maltreatment propose that child maltreatment is multiply determined by various risk factors that exist across different ecological systems. Intimate partner violence (IPV) often co-occurs with child maltreatment and may represent a pathway through which risk for child abuse and neglect is transmitted across generations within a family. Informed by theories on the intergenerational transmission of child maltreatment and utilizing a community-based, cross-sectional sample of 245 racially and ethnically diverse, low-income mothers and daughters, the objective of this study was to investigate IPV as a propagating process through which risk of child abuse and neglect is conferred from parent to child. We found evidence suggesting that mothers' history of maltreatment is associated with both their IPV involvement and their adolescent daughters' maltreatment victimization (with exposure to IPV as a maltreatment subtype excluded for clarity). Maternal IPV also partially accounted for the continuity of maltreatment victimization from mother to adolescent. A secondary analysis that included the adolescent's own engagement in dating violence provided compelling but preliminary evidence of the emergence of a similar pattern of relational violence, whereby adolescent girls with maltreatment histories were likewise involved in abusive intimate relationships. Future directions and clinical implications of these findings are discussed.

RESUMEN

The present study examined the effect of various dimensions of child maltreatment (i.e., developmental timing of maltreatment, number of maltreatment subtypes, and chronicity of maltreatment) on methylation of the glucocorticoid receptor gene, nuclear receptor subfamily 3, group C, member 1 (NR3C1), and investigated the associations between NR3C1 methylation and child outcomes. Participants included 534 children who attended a research summer camp program for school-aged maltreated (53.4%) and nonmaltreated (46.6%) children from low socioeconomic backgrounds. Results show that children with early onset maltreatment evidence significant hypermethylation compared to nonmaltreated children. Moreover, more maltreatment subtypes experienced and more chronic maltreatment are both related to greater NR3C1 hypermethylation. Findings also indicate that hypermethylation of NR3C1 is linked with a number of negative child outcomes including greater emotional lability-negativity, higher levels of ego undercontrol, more externalizing behavior, and greater depressive symptoms. Together, results highlight the role of methylation of NR3C1 in the effects of child maltreatment on the development of emotion dysregulation and psychopathology.

RESUMEN

The present study tested the role of FKBP5 binding protein 5 (FKBP5) genetic variation in an internalizing pathway from child maltreatment to emerging adult problem drinking among a sample of African American youth (N = 280) followed prospectively from ages 11 to 20. Specifically, whether childhood internalizing symptoms and emerging adult tension reduction alcohol expectancies sequentially mediate the effect of child maltreatment on emerging adult problem drinking and whether FKBP5 moderates these associations were investigated. The results indicate that individuals with at least one copy of the FKBP5 CATT haplotype (minor alleles) are more vulnerable to traversing the hypothesized internalizing pathway of risk than individuals without this genotypic profile. Taken together our findings highlight the importance of FKBP5 genetic variation in the context of early adversity; support the role of two prospective sequential mediators of an internalizing pathway to problematic drinking, namely, childhood internalizing symptoms and emerging adult tension reduction alcohol expectancies; and identify a subgroup of maltreated children most susceptible to progressing along this less common pathway of risk.

RESUMEN

Numerous investigations have demonstrated that child-parent psychotherapy (CPP) promotes secure attachment between mothers and offspring. However, the role of postintervention attachment security as it relates to long-term child outcomes has never been evaluated. The present study therefore examined postintervention attachment status as a mediator of the association between CPP for depressed mothers and their offspring and subsequent peer relations among offspring. Depressed mothers and their toddlers were randomized to receive CPP (n = 45) or to a control group (n = 55). A prior investigation with this sample indicated that offspring who received CPP attained significantly higher rates of secure attachment postintervention, whereas insecure attachment continued to predominate for offspring in the control group. The present study examined follow-up data of teachers' reports on participants' competence with classroom peers when they were approximately 9 years old. Findings indicated that children who received CPP were more likely to evidence secure attachments at postintervention, which in turn was associated with more positive peer relationships at age 9.
