PHDCN: Substance Use Follow-Up for Chicago Cohorts, 2000-2002

The Project on Human Development in Chicago Neighborhoods (PHDCN) Substance Use Follow-Up, Wave 3 is a longitudinal dataset from 2000-2002. It was adapted from the Composite International Diagnostic Interview (CIDI) and administered to subjects in Cohorts 15 and 18 to obtain information regarding specific drug use. The study was led by Felton J. Earls of Harvard University as part of a larger interdisciplinary study following over 6,000 children, adolescents, and young adults.

Use Cases

• Modeling longitudinal substance use trajectories based on repeated measures across waves.
• Analyzing risk factors for antisocial behaviors based on family, peer, and school influences mentioned in the study.
• Studying neighborhood-level effects on adolescent development in a large urban setting.
• Comparing substance use patterns between different age cohorts (15 and 18) over time.

Strengths

• Data is part of a large-scale longitudinal study following over 6,000 subjects.
• Measures are adapted from a standardized diagnostic instrument (Composite International Diagnostic Interview).
• Dataset is part of a coordinated series of waves, enabling temporal analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for this specific wave is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
