Despite previous gender-based studies of Gottfredson and Hirschi’s self-control theory, limited empirical attempts have been made outside of the Western hemisphere. This study is set to examine the cross-cultural and/or national boundaries generalizability of the self-control concepts in predicting gender differences on theft and violent delinquency in a rarely examined Hong Kong adolescent population. In addition, this study is among the first to investigate the age-effect gender differences on delinquency in the East. Using a cross-sectional design, 1,377 randomly selected native-Chinese secondary school–aged male and female adolescents of nine stratified randomly selected schools were surveyed. Multivariate analyses were used to examine gender differences, with and without controlling for the adolescent age, aside from the general offending propensity among Hong Kong adolescents with respect to their self-control level. Overall findings suggest that the relationship between low self-control indicators and types of delinquency differs across gender. Hence, findings of previous gender-based self-control studies conducted in the West are generally supported in this study. Implications, limitations, and future research directions are outlined.
