3-168 - Untangling the Complex Relations Between Early-life Adversity and Stress: Insights From Physiology and Longitudinal Modeling

Session Type: Paper Symposium

Integrative Statement

Research suggests that both early adversity and stress can have deleterious effects on the developing child. While some contend that early adversity and stress are inextricably linked, others argue that these contracts are largely orthogonal. Recent advanced in physiological and statistical methods have allowed for a more nuanced understanding of the intersection between early adversity and stress. As such, the present symposium aims to examine the complex relations between early adversity and stress using novel methods to assess chronic stress and longitudinal models that capture development in-context. The first presentation will focus on the relations between chronic stress production in the infant, as indexed by hair cortisol, and socioeconomic status using a multidimensional approach. The second presentation will build on first by using hair cortisol to examine how SES and stress predict longitudinal trajectories of child-directed speech using latent growth curve modeling. The third and final presentation utilizes growth mixture modeling to examine how longitudinal trajectories of early adversity and chronic poverty prospectively predict neural indices of reward responding during adolescence. Results will be discussed by an expert panelist and placed within the broader literature as well as recommendations for future research will be made.
