    Parsing Heterogeneity in Developmental Trajectories of Internalizing and Externalizing Symptomatology in the Adolescent Brain Cognitive Development Study

    Background: Psychopathology demonstrates marked changes within and between individuals across development, especially during the transition from childhood to adolescence. Evidence characterizing the directionality and rate of change across distinct dimensions of psychopathology has been mixed, with different studies indicating increases, decreases, or no change in internalizing and externalizing symptoms. Moreover, much remains unknown about the extent to which trajectories differ across individuals. Methods: Using a large, diverse national sample of youth (9-10 years old at baseline) from the Adolescent Brain Cognitive Development (ABCD) Study® (n = 6,405) we tested trajectories of psychopathology over three years. At each time point, parents reported their child’s internalizing and externalizing symptoms. Results: Results from a latent growth curve model indicated that, on average, externalizing symptoms decreased across the three time points, whereas internalizing symptoms did not significantly change. We then used growth mixture modeling to identify latent subgroups of pre-adolescents with distinct psychopathology trajectories. Results indicated that there were four different internalizing trajectories: a high-stable group, a moderate-decreasing group, a moderate-increasing group, and a low-decreasing group. For externalizing symptoms, there were three trajectories: a high-decreasing group, a moderate-increasing group, and a low-decreasing group. We also used parallel process growth analysis to examine the co-development of internalizing and externalizing symptoms and identified five subgroups with distinct patterns of co-development. These subgroups were differentially associated with sex and age. Conclusion: These findings highlight important heterogeneity in the development of psychopathology during pre-adolescence

    Psychopathology as Long-Term Sequelae of Maltreatment and Socioeconomic Disadvantage : Neurocognitive Development Perspectives

    Neuroscience research underscores the critical impact of adverse experiences on brain development. Yet, there is limited understanding of the specific pathways linking adverse experiences to accelerated or delayed brain development and their ultimate contributions to psychopathology. Here, we present new longitudinal data demonstrating that neurocognitive functioning during adolescence, as affected by adverse experiences, predicts psychopathology during young adulthood. The sample included 167 participants (52% male) assessed in adolescence and young adulthood. Adverse experiences were measured by early maltreatment experiences and low family socioeconomic status. Cognitive control was assessed by neural activation and behavioral performance during the Multi-Source Interference Task. Psychopathology was measured by self-reported internalizing and externalizing symptomatology. Results indicated that higher maltreatment predicted heightened frontoparietal activation during cognitive control, indicating delayed neurodevelopment, which, in turn predicted higher internalizing and externalizing symptomatology. Furthermore, higher maltreatment predicted a steeper decline in frontoparietal activation across adolescence, indicating neural plasticity in cognitive control-related brain development, which was associated with lower internalizing symptomatology. Our results elucidate the crucial role of neurocognitive development in the processes linking adverse experiences and psychopathology. Implications of the findings and directions for future research on the effects of adverse experiences on brain development are discussed.Peer reviewe

    Characterizing the dimensional structure of early-life adversity in the Adolescent Brain Cognitive Development (ABCD) Study

    Increasing evidence suggests that different dimensions of early-life adversity may be associated with unique neurodevelopmental mechanisms and behavioral outcomes. We sought to characterize the underlying dimensional structure of co-occurring adverse experiences among a subset of youth (ages 9-10) from the Adolescent Brain Cognitive Development (ABCD) Study (N = 7,115), a community sample of youth in the United States. We identified 60 environmental and experiential variables that reflect adverse experiences. Exploratory factor analysis identified 10 early-life adversity dimensions of co-occurrence, corresponding to conceptual domains such as caregiver substance use and biological caregiver separation, caregiver psychopathology, caregiver lack of support, and socioeconomic disadvantage / neighborhood lack of safety. These dimensions demonstrated distinct associations with internalizing problems, externalizing problems, cognitive flexibility, and inhibitory control. Non-metric multidimensional scaling characterized qualitative similarity among the 10 identified dimensions. Results supported a nonlinear three-dimensional structure representing early-life adversity, including continuous gradients of “perspective”, “environmental uncertainty”, and “acts of omission/commission”. Our findings suggest that there are distinct dimensions of early-life adversity in the ABCD sample at baseline, and the resulting dimensions may have unique implications for neurodevelopment and youth behavior

    Positive and negative affect and adolescent adjustment: moderation effects of prefrontal functioning

    We examined whether cognitive control moderates the effects of emotion on adolescent internalizing and externalizing symptomatology in a longitudinal study of 138 adolescents. Self-reported positive affect (PA) and negative affect and behavioral and neural indicators of cognitive control, indexed by performance and prefrontal hemodynamic response during a cognitive interference task, were collected at Time 1. Self-reported internalizing and externalizing symptomatology were collected at Time 1 and Time 2 (1year later). Results indicated that higher PA predicted decreases in externalizing symptomatology, but only for adolescents with poor neural cognitive control. No moderation effects were found for behavioral cognitive control. Findings imply the beneficial effects of PA on the development of externalizing problems among adolescents with poor prefrontal functioning

    Early-life adversity has profound consequences for youth neurodevelopment and adjustment; however, experiences of adversity are heterogeneous and interrelated in complex ways that can be difficult to operationalize and organize in developmental research. We sought to characterize the underlying dimensional structure of co-occurring adverse experiences among a subset of youth (ages 9–10) from the Adolescent Brain Cognitive Development (ABCD) Study (N = 7115), a community sample of youth in the United States. We identified 60 environmental and experiential variables that reflect adverse experiences. Exploratory factor analysis identified 10 robust dimensions of early-life adversity co-occurrence, corresponding to conceptual domains such as caregiver substance use and biological caregiver separation, caregiver psychopathology, caregiver lack of support, and socioeconomic disadvantage / neighborhood lack of safety. These dimensions demonstrated distinct associations with internalizing problems, externalizing problems, cognitive flexibility, and inhibitory control. Non-metric multidimensional scaling characterized qualitative similarity among the 10 identified dimensions. Results supported a nonlinear three-dimensional structure representing early-life adversity, including continuous gradients of “perspective”, “environmental uncertainty”, and “acts of omission/commission”. Our findings suggest that there are distinct dimensions of early-life adversity co-occurrence in the ABCD sample at baseline, and the resulting dimensions may have unique implications for neurodevelopment and youth behavior
