Pittsburgh Youth Study

The Pittsburgh Youth Study: Data Archiving and Ongoing Analyses

(Director: Dustin Pardini)
The Pittsburgh Youth Study consists of three cohorts of boys who were in the first, fourth, and seventh grades when the study began in 1987-1988 (called the youngest, middle, and oldest cohorts, respectively). Assessments were conducted semiannually and then annually using multiple informants (i.e., boys, parents, teachers). The youngest cohort was assessed from ages 6-19 and again at ages 25 and 28. The middle cohort was assessed from ages 9-13 and again at age 23. The oldest cohort was assessed from ages 13-25, with an additional assessment at age 35. Information has been collected on a broad range of risk and protective factors across multiple domains (e.g., individual, family, peer, school, neighborhood). Measures of conduct problems, substance use/abuse, criminal behavior, mental health problems have been collected. Participant retention has historically been high (mean=91%), with 82% of living men completing the most recent interview conducted in 2010.
