Abstract
Among youth from high-achieving schools, adverse childhood experiences (ACEs) were examined in relation to (a) internalizing and externalizing symptoms in adolescence (n = 527), and (b) symptoms plus psychiatric diagnoses-based on multiple annual interviews-in adulthood (n = 316). Also examined were associations for a "Proxy ACEs" (P-ACEs) measure, containing items similar to those on standard ACEs measures without reference to abuse or neglect. Rates of ACEs were comparable with those in other studies; most commonly endorsed were perceived parental depression followed by aspects of emotional neglect. Groups exposed to zero, 1, 2, 3, and 4+ ACEs differed on symptoms in adulthood, with small to moderate effect sizes; in parallel comparisons of P-ACEs groups on Grade 12 symptoms, differences had large effect sizes. In relation to psychiatric diagnoses, comparisons with the zero ACEs group showed that groups with 1, 2, 3 ACEs, versus 4+ ACES, respectively, had twofold and over fivefold greater odds of having any lifetime diagnosis. The odds for internalizing diagnoses specifically were 2-6 times greater for individuals with 1, 2, and 3 ACEs, and 12 times greater for those reporting 4 ACEs. Remarkably, Grade 12 reports of 2, 3, and 4+ P-ACEs were linked to 2-3 times greater odds of a psychiatric disorder in adulthood, and 3-6 times greater odds for internalizing diagnoses specifically. In the future, assessments of ACEs and P-ACEs could facilitate early detection of problems among HAS students, informing interventions to mitigate vulnerability processes and promote resilience among these youth and their families.
