RT Article T1 Adolescent Violent Delinquency Associated With Increased Emergency Department Usage in Young Adulthood JF International journal of offender therapy and comparative criminology VO 67 IS 8 SP 739 OP 756 A1 Portnoy, Jill A2 Schwartz, Joseph A. LA English YR 2023 UL https://krimdok.uni-tuebingen.de/Record/1843374773 AB Limited research has examined the extent to which adolescent delinquency predicts healthcare usage in young adulthood, including emergency department (ED) visits. This study used data from 3,310 adolescents (52.05% female; mean age at Wave I = 16.04 years) from the sibling subsample of the National Longitudinal Study of Adolescent to Adult Health (Add Health). We examined whether adolescent delinquency at Wave I predicted ED visits at Wave III using sibling fixed effects models to adjust estimates for within-family unobserved heterogeneity. Increased violent, but not nonviolent, delinquency predicted a higher number of ED visits in early adulthood in the sibling fixed effects models. To our knowledge, this is the first study to examine the relationship between delinquency and ED usage using a sibling fixed effects design. Findings demonstrate that violent adolescent delinquency may increase healthcare usage and suggest the potential role of healthcare providers in improving outcomes for delinquent youth.
