Early Associations Between Adversity and Child Behavioral Outcomes

Abstract

Research on adverse childhood experiences (ACEs) has demonstrated the high prevalence rates of such experiences, with about 60% of individuals in national U.S. samples reporting one or more types of ACEs as children (Chapman et al., 2013; Finkelhor et al., 2015). Further, research has established robust links between ACEs and a range of negative behavioral and health outcomes in adulthood (Felitti et al., 1998; Hughes et al., 2017; Kalmakis & Chandler, 2015; Wang et al., 2020; Wang & Maguire-Jack, 2018; Wolff et al., 2018). Less is known about when potential negative consequences of ACEs exposure emerge. The few studies that have examined the relationship between ACEs and early outcomes have employed inconsistent modeling strategies which has left the functional form of the relationship unclear, which could lead to either under-or over-estimating the risk associated with various levels of ACEs exposure (Crouch et al., 2019; Hughes et al., 2017; Lanier et al., 2018; Wang et al., 2019). Further, these studies have not comprehensively examined the potential moderating role of socio-ecological factors like neighborhood context. Theoretical frameworks suggest neighborhood resources might buffer children from negative consequences associated with ACEs while exposure to neighborhood-level adversities might exacerbate negative consequences. In order to address these gaps, the currently study examined the functional form of the relationship between ACEs experienced in the first four years of life and kindergarten behavioral outcomes and tested the moderating role of neighborhood resources and neighborhood adversities in a large, nationally representative sample of young children drawn from the Early Childhood Longitudinal Study - Birth Cohort (ECLS-B; N ≈ 10,700) linked with neighborhood administrative data. Using inverse probability weighting to strengthen internal validity, numerous modeling strategies supported a linear relationship between early childhood ACEs and kindergarten behavioral outcomes. Greater ACEs exposure was associated with significantly lower prosocial skills and significantly higher externalizing behavior problems, with small effect sizes of 0.075 to 0.143 standard deviation shifts in behaviors for each additional ACEs exposure. Interaction models found that ACEs were significantly associated with behavioral consequences regardless of neighborhood context. Overall, the robust modeling strategies employed provide the strongest evidence to date of the significant, linear relationship between ACEs and early behavioral consequences.
