Children’s relationships inform their internal working models (IWMs) of the world around them. Attachment and emotional security theory (EST) emphasize the importance of parent–child and interparental relationships, respectively, for IWM. The current study examined (a) data-driven classes in child attachment and emotional security IWM, (b) associations between IWM classes and demographic variables, maltreatment, intimate partner violence (IPV), and maternal depressive symptoms, and (c) consistency in attachment and emotional security IWM classes, including as a function of maltreatment, IPV, and maternal depressive symptoms. Participants were 234 preschool-aged children (n = 152 experienced maltreatment and n = 82 had not experienced maltreatment) and their mothers. Children participated in a narrative-based assessment of IWM. Mothers reported demographics, IPV, and maternal depressive symptoms. Latent class analyses revealed three attachment IWM classes and three emotional security IWM classes. Maltreatment was associated with lower likelihood of being in the secure attachment class and elevated likelihood of being in the insecure dysregulated attachment class. Inconsistencies in classification across attachment and emotional security IWM classes were related to maltreatment, IPV, and maternal depressive symptoms. The current study juxtaposes attachment and EST and provides insight into impacts of family adversity on children’s IWM across different family relationships.

Heavy episodic drinking (HED) is a major public health concern, and youth who engage in HED are at increased risk for alcohol-related problems that continue into adulthood. Importantly, there is heterogeneity in the onset and course of adolescent HED, as youth exhibit different trajectories of initiation and progression into heavy drinking. Much of what is known about the etiology of adolescent HED and alcohol-related problems that persist into adulthood comes from studies of predominantly White, middle-class youth. Because alcohol use and related problems vary by race/ethnicity and socioeconomic status, it is unclear whether previous findings are relevant for understanding developmental antecedents and distal consequences of adolescent HED for minoritized individuals. In the current study, we utilize a developmental psychopathology perspective to fill this gap in the literature. Using a racially and economically diverse cohort followed from adolescence well into adulthood, we apply group-based trajectory modeling (GBTM) to identify patterns of involvement in HED from age 14 to 17 years. We then investigate developmental antecedents of GBTM class membership, and alcohol-related distal outcomes in adulthood (∼ age 31 years) associated with GBTM class membership. Results highlight the importance of adolescent alcohol use in predicting future alcohol use in adulthood.

Understanding how youth perceive household economic hardship and how it relates to their behavior is vital given associations between hardship and behavioral development. Yet, most studies ignore youth’s own perceptions of economic hardship, instead relying solely on caregiver reports. Moreover, the literature has tended to treat economic hardship as a stable force over time, rather than a volatile one that varies month-to-month. This study addressed extant limitations by collecting monthly measures of economic hardship, specifically caregiver- and youth-reported material deprivation and youth-reported financial stress, and youth internalizing and externalizing problems from 104 youth–caregiver dyads (youth: 14–16 years, 55% female, 37% Black, 43% White) over nine months. We examined month-to-month variability of these constructs and how youth-reports of material deprivation and financial stress predicted their behavior problems, controlling for caregiver-reports of material deprivation. We found that hardship measures varied month-to-month (ICCs = 0.69–0.73), and youth-reported material deprivation positively predicted internalizing when examining both within- and between-individual variability (β = .19–.47). Youth-reported financial stress positively predicted within-individual variation in externalizing (β = .18), while youth reports of material deprivation predicted externalizing when looking between families (β = .41). Caregiver-reported material deprivation was unrelated to youth behavior when accounting for youth perceptions of economic hardship.

Guided by the evolutionary perspective and specialization hypothesis, this multi-method (behavioral observation, questionnaire) longitudinal study adopted a person-centered approach to explore children’s problem-solving skills within different contexts. Participants were 235 young children (M age = 2.97 years at the first measurement occasion) and their parents assessed in two measurement occasions spaced one year apart. Latent profile analyses revealed four unique problem-solving profiles, capturing variability in children’s performance, and observed engagement in abstract vs. reward-oriented (RO) problem-solving tasks at wave one. The four profiles included: (a) a high-abstract-high-RO, (b) a high-abstract-low-RO, (c) a low-abstract-high-RO, and (d) a low-abstract-low-RO classes. Contextual risks within and outside families during wave one, including greater neighborhood crime, impoverishment, and observed lower maternal sensitivity were linked to the elevated likelihood for children from the two profiles with low-abstract problem-solving, particularly those from the low-abstract-high-RO problem-solving profile. Furthermore, child problem-solving profiles were linked to meaningful differences in their socioemotional functioning one year later. The present finding has important implications in revealing the heterogeneity in child problem-solving within different contexts that responded differently to contextual risks. In addition, this study advanced the understanding of the developmental implications of child problem-solving capacity.

Children who have experienced maltreatment are more likely to have disrupted attachments, fewer psychosocial strengths, and poorer long-term psychosocial outcomes. However, few studies have examined the interplay between attachment security and psychosocial strengths among children involved in therapeutic services in the context of the child welfare system. The present longitudinal study examines the insecure attachment behaviors and psychosocial strengths of 555 children referred to the Therapeutic Family Care program (TFCP) in Cobourg, Ontario between 2000 and 2019. The children were assessed by their caregivers on a regular basis using the Assessment Checklist for Children (ACC) and the complementary strengths-focused ACC+ measure. Average age of children at baseline was 9.57 years (SD = 3.51) and 229 (41.26%) were female. We conducted growth curve and random intercepts cross-lagged panel models to test the longitudinal interplay between insecure attachment behaviors and strengths. Results suggest that females’ attachment security improved, males’ attachment security worsened, and both males and females developed strengths over time. Further, analyses revealed a directional effect, whereby fewer insecure attachment behaviors predicted more psychosocial strengths approximately 6 months later. Implications for attachment-oriented and strengths-based services in the context of child welfare are discussed.

Adolescent pregnancy (AP) is a significant public health issue. Child maltreatment (CM) represents an established risk factor, yet little is known about the explanatory mechanisms linking the phenomena. Informed by developmental theory, this study prospectively tested seven multi-level, indirect pathways that could plausibly explain the relationship between CM and AP: (1) substance use (polysubstance use and frequency); (2) sexual risk behavior; (3) depressive symptoms; (4) posttraumatic stress disorder symptoms; (5) cognitive dysregulation; (6) pregnancy desire and difficulty expectancies; and (7) age at menarche. Data came from a prospective, longitudinal cohort study of 469 ethnically diverse, nulliparous adolescent females, designed to examine the impact of substantiated CM on reproductive outcomes such as pregnancy and childbirth (265 maltreated and 204 demographically matched comparison adolescents). A multiple-mediator structural equation model was conducted to simultaneously test multiple indirect effects while accounting for confounding variables. Maltreatment had an indirect effect on pregnancy via substance use and higher pregnancy desire/lower perceived difficulty. Findings represent a step towards elucidating pathways linking CM with AP. Recommendations are offered to prevent pregnancy by addressing the pregnancy-specific mechanisms that are part of the maltreatment sequelae.

This 20-year prospective study examined verbal aggression and intense conflict within the family of origin and between adolescents and their close friends as predictors of future verbal aggression in adult romantic relationships. A diverse community sample of 154 individuals was assessed repeatedly from age 13 to 34 years using self-, parent, peer, and romantic partner reports. As hypothesized, verbal aggression in adult romantic relationships was best predicted by both paternal verbal aggression toward mothers and by intense conflict within adolescent close friendships, with each factor contributing unique variance to explaining adult romantic verbal aggression. These factors also interacted, such that paternal verbal aggression was predictive of future romantic verbal aggression only in the context of co-occurring intense conflict between an adolescent and their closest friend. Predictions remained robust even after accounting for levels of parental abusive behavior toward the adolescent, levels of physical violence between parents, and the overall quality of the adolescent’s close friendship. Results indicate the critical importance of exposure to aggression and conflict within key horizontal relationships in adolescence. Implications for early identification of risk as well as for potential preventive interventions are discussed.

Longitudinal trajectories of psychopathology in previously institutionalized (PI) youth were identified and biobehavioral emotion regulation processes were examined as developmental mechanisms that predict these trajectories. Mental health data were collected from PI (N = 132) and nonadopted (NA; N = 175) youth across four time points (participant age ranged from 7- to 21-year-old). Using semiparametric group-based methods, the probability that each individual belonged to a distinct group that followed a specific pattern of behavior across time was estimated. We then tested whether unique aspects of emotion regulation (global, observed, and biological) were differentially associated with membership in externalizing and internalizing trajectory groups using multinomial logistic regression models. Four externalizing trajectories were identified for the PI and NA groups. For PI youth, global, observed, and biological emotion regulation processes were uniquely predictive of more adaptive externalizing trajectories. For NA youth, only parent-reported global emotion regulation was predictive of externalizing patterns. Three internalizing trajectories were identified for PI and NA youth. Generally, only parent-reported global emotion regulation predicted internalizing group membership for both PI and NA youth. Results suggest that biobehavioral emotion regulation processes may be particularly important predictors and potential points of intervention when targeting trajectories of externalizing behaviors in PI children.

Research on the longitudinal courses of child social–emotional symptoms and sleep during the COVID-19 pandemic within societies would be of key value for promoting child well-being in global crises. We characterized the course of children’s social–emotional and sleep symptoms before and throughout the pandemic in a Finnish longitudinal cohort of 1825 5- to 9-year-old children (46% girls) with four follow-up points during the pandemic from up to 695 participants (spring 2020–summer 2021). Second, we examined the role of parental distress and COVID-related stressful events in child symptoms. Child total and behavioral symptoms increased in spring 2020 but decreased thereafter and remained stable throughout the rest of the follow-up. Sleep symptoms decreased in spring 2020 and remained stable thereafter. Parental distress was linked with higher child social–emotional and sleep symptoms. The cross-sectional associations between COVID-related stressors and child symptoms were partially mediated by parental distress. The findings propose that children can be protected from the long-term adverse influences of the pandemic, and parental well-being likely plays a mediating role between pandemic-related stressors and child well-being. Further research focusing on the societal and resilience factors underlying family and child responses to the pandemic is warranted.

This study addressed the role of deficits in the organization of the self, or narcissistic pathology, among widows who evidenced depressive outcomes following the loss of their husbands. The significance of object representations and self-regulatory capacities (introjects) within the self-representation in predicting psychiatric status in a sample of 77 widows 1 year after spousal loss was examined. In addition, the link between functional deficits within the self and observable state markers of such deficits as they related to depression was investigated. A combination of projective and self-report measures were used to assess self and object representation. The General Health Questionnaire (Goldberg & Hillier, 1979) and the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders (3rd ed.) (Spitzer & Williams, 1985) were employed as measures of psychiatric disorder. Analyses revealed that functional aspects of self representations, or introjects, differentiated clinically depressed widows from those experiencing “normal” mourning. However, object representations were relatively weak predictors of depression following bereavement and evidenced little association with self representation. Observable markers of self-pathology were strongly related to functional impairments in the self but did not operate causally to predict depressive outcome. Theoretical and clinical implications of the linkage between functional deficits in the self and depression are discussed.

In a sample of 112 psychiatric inpatients with mild mental retardation, lower premorbid social competence was significantly related to symptom expression in action compared to thought. Both of these variables were correlated with length of current hospitalization. Premorbid social competence and thought-action orientation have been major variables in developmental research on psychopathology in patients without mental retardation. These results indicate that these variables can be applied to differentiate developmental level among inpatients with mild mental retardation and that these developmental distinctions are related to other clinical variables, as has been found for inpatients without mental retardation. The findings also attest to the heterogeneity in developmental level among inpatients with mild mental retardation.

Indices of cumulative risk (CR) have long been used in developmental research to encode the number of risk factors a child or adolescent experiences that may impede optimal developmental outcomes. Initial contributions concentrated on indices of cumulative environmental risk; more recently, indices of cumulative genetic risk have been employed. In this article, regression analytic methods are proposed for interrogating strongly the validity of risk indices by testing optimality of compositing weights, enabling more informative modeling of effects of CR indices. Reanalyses of data from two studies are reported. One study involved 10 environmental risk factors predicting Verbal IQ in 215 four-year-old children. The second study included an index of genetic CR in a G×E interaction investigation of 281 target participants assessed at age 15 years and then again at age 31 years for observed hostility during videotaped interactions with close family relations. Principles to guide evaluation of results of statistical modeling are presented, and implications of results for research and theory are discussed. The ultimate goals of this paper are to develop stronger tests of conjectures involving CR indices and to promote methods for improving replicability of results across studies.

This multi-method longitudinal study evaluated how changes in maternal sensitive parenting may operate as an indirect factor linking family instability and the development of child externalizing problems over time. This study also investigated how mothers’ stress reactivity within the sympathetic nervous system (SNS) may moderate the association between family instability and the development of maternal sensitivity. Participants were 235 families with a young child (Mage = 2.97 years at the first measurement occasion) and these families were followed for two annual measurement occasions. Maternal sensitivity was observed during two discipline tasks (i.e., forbidden toy, discipline discussion tasks), and maternal SNS stress reactivity was indicated by their salivary alpha-amylase (sAA) reactivity to an interpersonal stressor. Findings revealed significant direct effects of family instability and family instability-x-sAA reactivity interaction in association with the change in maternal sensitivity over time. For both tasks, mothers with greater sAA reactivity exhibited stronger associations between family instability and the growth of their sensitivity. Tests of indirect effects indicated that change in maternal sensitivity operated as an indirect factor between family instability-x-sAA reactivity interaction and the change in child externalizing problems. The present findings have important implications for understanding parental and child sequelae associated with unstable family contexts.

Peer victimization and depressive symptoms are highly relevant risks during adolescence. Understanding the dynamic patterns of interactions between peer victimization and depressive symptoms as well as gender differences in these variables can improve intervention strategies for adolescents navigating this critical transition period. In the present study, a large sample of Chinese adolescents reported peer victimization and depressive symptoms in four survey waves at six-month intervals. A total of 2534 adolescents (51.9% boys, M = 12.98 ± 0.60 years) were included in the latent change score (LCS) analysis. The results supported the reciprocal effects model obtained in the full sample. Changes in peer victimization were influenced by prior changes in depressive symptoms over time, and changes in depressive symptoms were influenced by prior levels of peer victimization. There were also gender differences, with boys exhibiting depressive symptom-driven effects on peer victimization, while girls exhibiting peer victimization-induced depressive symptoms. The dynamic relationships between peer victimization and depressive symptoms that promote and constrain each other in adolescents are elucidated in this study. Differentiating effects on boys and girls is crucial for enhancing the effectiveness of practical interventions.

Negative emotionality (NE) was evaluated as a candidate mechanism linking prenatal maternal affective symptoms and offspring internalizing problems during the preschool/early school age period. The participants were 335 mother–infant dyads from the Maternal Adversity, Vulnerability and Neurodevelopment project. A Confirmatory Bifactor Analysis (CFA) based on self-report measures of prenatal depression and pregnancy-specific anxiety generated a general factor representing overlapping symptoms of prenatal maternal psychopathology and four distinct symptom factors representing pregnancy-specific anxiety, negative affect, anhedonia and somatization. NE was rated by the mother at 18 and 36 months. CFA based on measures of father, mother, child-rated measures and a semistructured interview generated a general internalizing factor representing overlapping symptoms of child internalizing psychopathology accounting for the unique contribution of each informant. Path analyses revealed significant relationships among the general maternal affective psychopathology, the pregnancy- specific anxiety, and the child internalizing factors. Child NE mediated only the relationship between pregnancy-specific anxiety and the child internalizing factors. We highlighted the conditions in which prenatal maternal affective symptoms predicts child internalizing problems emerging early in development, including consideration of different mechanistic pathways for different maternal prenatal symptom presentations and child temperament.

The body of scientific knowledge accumulated by the scholarly disciplines such as Developmental Psychopathology can achieve meaningful public impact if wielded and used in policy decision-making. Scientific study of how policymakers use research evidence underscores the need for researchers’ policy engagement; however, barriers in the academy create conditions in which there is a need for infrastructure that increases the feasibility of researchers’ partnership with policymakers. This need led to the development of the Research-to-Policy Collaboration model, a systematic approach for developing “boundary spanning” infrastructure, which has been experimentally tested and shown to improve policymakers’ use of research evidence and bolster researchers’ policy skills and engagement. This paper presents original research regarding the optimization of the RPC model, which sought to better serve and engage scholars across the globe. Trial findings shed light on ways to improve conditions that make good use of researchers’ time for policy engagement via a virtual platform and enhanced e-communications. Future directions, implications, and practical guidelines for how scientists can engage in the political process and improve the impact of a collective discipline are also discussed.
