The purpose of the current study was to determine whether there were differences between Hmong immigrant siblings on multiple nonshared individual, school, and family variables. Participants were 58 sibling pairs (29 delinquent pairs and 29 nondelinquent pairs), who ranged in age from 13 to 21 years. There were 11 pairs of boys, 3 pairs of girls, and 15 pairs of opposite-sex siblings. Results of a multivariate analysis of variance indicated that delinquent and nondelinquent sibling groups were significantly different in participation in organized activities, antisocial attitudes, delinquent behaviors, school truancy, school performance, and parents' labeling. The findings have implications for future research on sibling delinquency in Hmong immigrant families and for program development and delivery.
