Multisystem Environmental Factors Elucidate Shared and Distinct Associations With Brain and Behavior in Adolescents.

objectiveEnvironmental factors have long been shown to influence brain structure and adolescent psychopathology. However, almost no research has included environmental factors spanning micro-to-macro-systems, brain structure, and psychopathology in an integrated framework. Here, we assessed the ways and degree to which multisystem environmental factors during late childhood are associated with subcortical volume and psychopathology during early adolescence.

methodWe used baseline, 2-year follow-up, and 3-year follow-up data from the Adolescent Brain Cognitive Development℠ Study (n = 2,766). A Bayesian latent profile analysis was applied to obtain distinct multisystem environmental profiles during late childhood. The profiles were used in a path analysis to derive their direct and indirect effects on subcortical volume and psychopathology during early adolescence.

resultsBayesian latent profile analysis revealed 9 environmental profiles. Two distinct profiles were directly associated with greater externalizing psychopathology in adolescents: (1) adversity across family, school, and neighborhood systems, and (2) family conflict and low school involvement. In contrast, a profile of family and neighborhood affluence was directly associated with lower externalizing psychopathology. Furthermore, family/neighborhood affluence was associated with higher subcortical volume, which in turn was associated with lower externalizing and internalizing psychopathology; conversely, a family economic and neighborhood adversity profile was associated with lower subcortical volume, which in turn was associated with higher externalizing and internalizing psychopathology.

conclusionWe identified environmental and brain-related equifinal pathways associated with externalizing and internalizing psychopathology. This work highlights the importance of considering the role of multiple systems and factors in the conceptualization and treatment of adolescent psychopathology. PLAIN LANGUAGE SUMMARY: Environmental factors have been shown to influence brain structure and adolescent mental health. Utilizing data from the Adolescent Brain Cognitive Development℠ (ABCD) Study (n = 2,766), the authors investigated the relationships of environmental profiles on brain development and mental health during early adolescence. The authors identified distinct environmental and brain-related pathways associated with externalizing and internalizing mental health problems. Adversity across family, school, and neighborhood systems; family conflict; and low school involvement were identified as part of the profiles associated with greater externalizing psychopathology in adolescents. This work highlights the importance of considering multiple systems and factors in the conceptualization and treatment of adolescent mental health.
