Objectives: An Antisocial Behavior index (ASB-I) for children (ages 5 to 15) was previously developed by obtaining clinician ratings of the seriousness or severity of various behaviors with the goal of improving assessment of antisocial behaviors (ASB) longitudinally. We extend the instrument for use in late adolescence/young adulthood, as socially unacceptable conduct manifests differently across developmental stages. As in the original study, this extension (the ASB-I YA) is based on independent ratings of ASB seriousness/severity during late adolescence/young adulthood (16 to 28 years) made by nine experienced clinicians. Methods: The items rated were drawn from the Oppositional Defiant Disorder and Conduct Disorder schedules of the NIMH Diagnostic Interview Schedule for Children (DISC-IV) and the Elliott Delinquency scales, plus new or modified items developmentally appropriate for late adolescence/young adulthood. Specific ratings were based on the developmental stage and reported frequency of the behaviors. The study also describes the distribution of ASB-I YA scores in the Boricua Youth Study. Results: Reliability was substantial for the average ratings of each subscale and for the total score [ICC(3,9): 0.88 to 0.95]. Certain items were rated as more severe when occurring in late adolescence/young adulthood compared to childhood/early adolescence (e.g., hitting someone on purpose); however, most ratings were similar across developmental periods. Most importantly, raters reliably and consistently rated the items describing ASB in young adulthood, allowing the computation of the ASB-I YA score 8. Conclusions: Together with the ASB-I, the ASB-I YA can further advance the study of ASB progression from childhood into young adulthood.
