Cumulative Adverse Childhood Experiences (ACEs) and Recidivism: A Meta-Analysis

This meta-analysis quantitatively synthesizes existing literature to investigate the relationship between aggregations of adverse childhood experiences (ACEs) and recidivism among court-involved youth and adults. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed, and moderation analyses were conducted. Sixteen studies (published n = 12), encompassing 101,778 unique participants (girls/women = 21.1%; adults n = 1,204), met the inclusion criteria. A small overall effect size revealed that an accumulation of ACEs increased the odds of reoffending. The relationship between ACEs and recidivism was only statistically significant for the subgroup of studies using youth samples. In addition, ACEs only predicted recidivism in the subgroup of published studies (compared to dissertations). Other moderators (gender, study location, recidivism time frame) were not significant. Our results suggest that courts, particularly youth courts, would benefit from screening for cumulative ACEs to help identify those most at risk for reoffending and in need of intervention.
