A test of classic strain theory on gender in relation to assault, school delinquency, and public disturbance is investigated in high schools in Ankara, the capital of Turkey. Data for the study, including class variables, involve a two-stage stratified cluster sample of high school students. The findings show that various strain and class measures do not appear to be associated consistently with delinquency and gender, except for perceived blocked opportunity for females. The effects of strain and class variables on delinquent acts are similar for both genders, except for the middle social class of males. The most striking finding is that social class is associated positively with juvenile delinquency: Lower-class youth are less likely to commit assault, school delinquency, and public disturbance.
