Oregon Youth Study Three Generational Study, Multi-Wave, 1995-2022

This study is part of the Oregon Youth Study (OYS), which began in 1983 and has now become the Three Generational Study (3GS). The aim of the original study was to examine the etiology of antisocial behaviors in boys, with the longer-term goal of designing preventative interventions. The longitudinal study expanded to include data collection regarding the relationships between the original male respondents, their romantic partners, and their offspring. This particular study focuses on the biological mothers and fathers (original OYS respondents) of offspring in the Three Generational Study. Data is collected across multiple waves, spanning from 1995 to 2022. It provides supplemental information that supports the continuing aims of the various waves within the OYS and 3GS studies. It examines the familial and personal history of the adult respondents, examining intergenerational trends of social behavior, alcohol and substance use, criminal behavior, mental health, and medical history. In particular, it includes detailed information about the personal history of the biological mothers of 3GS offspring.
