The impact of childhood stressful life events on health and behavior in at-risk youth

Abstract

Stressful life events experienced in childhood affect heath throughout the lifespan. Given the high prevalence of stressful life events, especially for children at-risk for child welfare involvement, the impacts of these events across different developmental stages need to be better understood. The current study examines the relation between previously experienced stressful life events and psychosocial health and risk behaviors in adolescence. Several links between maltreatment and psychosocial health were found. Namely, youth who had experienced sexual abuse were more likely to report anxious arousal symptoms, youth who had experienced physical maltreatment and emotional maltreatment were more likely to drop out of school, and youth who had experienced neglect were more likely to dropout, have unprotected sex and use cigarettes. Latent class analysis of life events revealed three groups of children with certain patterns of life events: Chronic, Moderate/Declining, and Low Life Events. After accounting for gender, race, and exposure to maltreatment, members of the Chronic Life Events group uniquely and significantly predicted higher likelihood of Anger/Irritability, Depression, Intrusive Experiences, and Dissociation on the Trauma Symptom Inventory at age 18. Additionally, members of the Chronic Life Events group were significantly more likely to drop out of school, have more sexual partners, be arrested more often and use marijuana or other illicit drugs more often. Membership in the Moderate/Declining Life Events group was significantly associated with likelihood of dropping out of school. The amount of stressful life events appears to be strong predictors of psychosocial outcomes and risk behaviors in adolescence. Efforts to intervene and prevent childhood exposure to stressful life events—particularly in children at-risk and/or maltreated—should begin early in life and continue throughout childhood and adolescence.
