Hyperactivity and Impulsivity Symptoms Mediate the Association Between Adverse Childhood Experiences and Reading Achievement: A LONGSCAN Cohort Study.

Abstract

Adverse Childhood Experiences (ACEs) include various childhood stressors that can negatively impact the health and well-being of children. ACEs are associated with poor academic achievement. Attention is strongly associated with academic achievement, and there is a graded relationship between ACEs exposure and subsequent development of parent-reported ADHD; however, it is unclear whether ADHD symptoms mediate the relationship between ACEs and academic achievement. This study tested a model of mediation by ADHD symptoms between ACEs and academic achievement (measured by reading score).This retrospective cohort analysis utilized data from the Longitudinal Study on Child Abuse and Neglect (LONGSCAN), a data consortium exploring the impact of child maltreatment (n = 494). There were relatively even numbers of male and female child participants, and the majority of caregivers were either non-Hispanic White or Black. Path analyses were modeled for ACEs as a sum score and separately for individual ACE exposures, with number of symptoms of Inattention (IN) and Hyperactivity/Impulsivity (H/I) as mediators, and academic achievement as the outcome, adjusting for covariates.ACEs were highly prevalent in this sample (M = 5.10, SD = 1.90). After retaining significant covariates, significant direct associations (P < .05) were seen between ACE sum score and IN (β = .14) and H/I (β = .21), and between H/I and reading score (β=-.14). A higher ACE score was associated with lower reading scores through variation in H/I, but not IN.H/I mediated the relationship between ACEs and reading score in this high-risk population, providing new insight into relationships between ACEs and academic achievement, which can inform interventions.
