title: Oregon Youth Study Three Generational Study, Multi-Wave, 1995-2022
title: Version 1

description: 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.
description: The purpose of this study is to integrate one-time and periodic updates about the biological parents of 3GS offspring, in order to provide supplemental information that may have been overlooked in the original study waves. It supports the overall aim of the Three Generational Study to examine intergenerational trends through the lens of social behavior, mental health, substance use, and familial history. It specifically focuses on measuring the intergenerational trends and personal history of OYS-3GS biological mothers.
description: This is study is based on a comprehensive model for intergenerational studies to examine family influences on healthy development and maladjustment.
description: This study includes detailed information about the familial history of respondents, including the social behavior and substance use of their parents and family members. It includes sensitive personal history including alcohol and substance use, history during pregnancy (for 3GS biological mother respondents), suicidal history, and trends in mental health and social behavior. It also includes an assessment of the level of vocabulary of 3GS biological mothers.
description: The sample includes the original male respondents from the Oregon Youth Study, as well as the biological mothers of their offspring.
