The Johns Hopkins University Prevention Research center - Risks for Transitions, Baltimore city, 2008-2011 study (JHU PRC Risks for Transition in Drug Use among Urban Adults) represents data collected for a 25 years follow-up from the original JHU PRC study. At the start of the data collection, a cohort of 2,311 youth were randomly assigned to two classroom-based universal preventive interventions implemented in 43 classrooms of 19 public schools located in 5 socio-demographically distinct areas in Eastern Baltimore. This collection includes data from 1,434 respondents from the original cohort collected in 2008-2012. The mean age of the respondents was 30-32 years old.

Psychopathology (major depressive episode, phobia and anxiety disorders) was assessed using modules from the Composite International Diagnostic Interview-University of Michigan Version, CIDI- UM (WHO, 1997). An antisocial symptom scale adapted from the National Epidemiologic Survey of Alcohol and Related Conditions (NESARC) was administered which consisted of 30 questions that assessed behaviors experienced since turning 18 years of age. The alcohol, tobacco and drug modules of the interview were modeled after NESARC Alcohol Use Disorder and Associated Disabilities Interview Schedule-IV. Types of information in these modules collected include age of onset, use in past year and prior past year, frequency and recency of use, and DSM-IV abuse and dependence criteria. Socioeconomic status indicators, variables on education, employment, marital status, parenthood, social supports, family history of mental health and drug problems, general health, treatment utilization, and life events are included in this dataset.

This dataset includes 3,140 variables.

Oregon Youth Study Three Generational Study, Time 6, 2004-2022 (ICPSR 39051)

Released/updated on: 2025-12-09
Geographic coverage: Oregon, United States
Time period: 2004-01-01--2022-01-01
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 offspring of the original OYS respondents, with targeted ages of 11-12 years. It examines the cognitive and social behavior of both offspring and parents. The rationale for examining the data is to track intergenerational trends in social behavior and health, with the aim to develop preventative interventions in the future.
