Oregon Youth Study

The Oregon Youth Study is a long-term longitudinal study that began in 1983 to examine the etiology of antisocial behavior in boys, including contextual data from their family, peer, and school environments. Over time, the Oregon Youth Study expanded into an intergenerational study (today known as the Three Generational Study, or 3GS), which retained the original participants and their partners and children. The study’s Principal Investigator is Deborah Capaldi, PhD, Senior Research Scientist at the Oregon Social Learning Center.
