This study examined the relationship between a history of maltreatment, spe
cifically physical abuse and sexual victimization. and three measures of de
linquency among a sample of 2,466 Mexican-American (MA) and non-Hispanic Wh
ite (NHW) adolescents between the ages of twelve and eighteen. Responses fr
om self-administered questionnaires were analyzed to determine (1) whether
physical abuse and sexual victimization were related to different types of
self-reported adolescent offending; and (2) whether these relationships var
y by ethnicity. Findings indicated that a history of physical abuse or sexu
al victimization significantly increased the likelihood of delinquent invol
vement in property, violent, and sex offending. The research also demonstra
ted that the effect of physical abuse on the three measures of delinquency
was similar for both MA and NHW, but that the effect of sexual assault on v
iolent offending was more pronounced among NHW adolescents. Directions for
future research are discussed. (C) 2001 Elsevier Science Ltd. All rights re
