Associations between potentially traumatic events and psychopathology among preadolescents in the Adolescent Brain and Cognitive Development Study®.

Abstract

The current cross-sectional study aimed to extend the literature on childhood adversity by examining the unique associations between potentially traumatic events (PTEs) and a range of mental health concerns, including domain-specific versus comorbid concerns. Participants were 11,877 preadolescents (47.8% female, 15.0% Black, 20.3% Hispanic/Latinx, Mage =9.5 years) taking part in the Adolescent Brain and Cognitive Development (ABCD) Study® . The Kiddie Schedule for Affective Disorders and Schizophrenia was used to measure PTEs and caregiver- and child-reported mental health concerns. Adjusted odds ratios (aORs) were used for the outcomes of interest. Overall, PTEs were consistently associated with increased odds of experiencing comorbid posttraumatic stress disorder (PTSD), internalizing disorders, and externalizing disorders, significant AORs=1.34-4.30, after accounting for children's experiences of other PTEs and polyvictimization. In contrast, PTEs were generally not associated with meeting the criteria for diagnoses within only one domain (i.e., internalizing-only or externalizing-only diagnoses). We also found PTEs to be differentially related to the various mental health outcomes. In particular, witnessing domestic violence was consistently associated with children's psychopathology. Other PTEs, such as witnessing community violence, were not associated with children's psychopathology in the final model. Associations between PTEs and mental health concerns did not differ as a function of sex. Overall, the results support the notion that PTEs are associated with comorbid concerns rather than individual disorders. These findings have important implications for the screening of PTEs, continued research on the conceptualization of traumatic stress, and the importance of accounting for comorbidities across mental health domains.
