Objective: To examine disparities in hazardous and harmful drinking, illicit drug use, delinquency, and psychological distress among three immigrant generations of youth. Methods: Data on 4,069 students were derived from the 2005 cycle of the Ontario Student Drug Use Survey, a province-wide school-based survey of 7 th to 12 th graders. The survey employed a two-stage cluster design (school, class). Analyses include adjustments for the complex survey design, specifically stratification, clusters, and weights. Results: Both drug use and hazardous and harmful drinking increase across immigrant generations. First-generation youth report significantly less use than second-generation youth, who in turn report less use than third and later generations. Generational differences in the levels of hazardous and harmful drinking increase with age. Delinquency is significantly less among first-generation youth relative to youth of other immigrant generations. Symptoms of psychological distress are highest among first-generation youth compared to youth of other immigrant generations. Conclusion: The nature of differences between foreign- and native-born adolescents varies across behaviours. As such, it is important to gain knowledge about the adjustment levels of these two groups with regard to specific components of well-being. Such knowledge is necessary for developing policies and programs to promote emotional and behavioural health. © Canadian Public Health Association, 2009. All rights reserved.
