PHDCN: Relationships Survey for Chicago Cohorts, 1997-2000

Over 6,000 randomly selected children, adolescents, and young adults were followed in the Project on Human Development in Chicago Neighborhoods (PHDCN) Longitudinal Cohort Study. The Relationships protocol, a self-administered packet for Cohorts 12, 15, and 18, collected information on dating, attitudes toward sex and having babies, and experience with sexual intercourse. This wave of data was collected between 1997 and 2000 by researchers including Felton J. Earls of Harvard University.

Use Cases

• Modeling predictors of adolescent sexual behavior based on attitudes and dating information mentioned in the description.
• Analyzing the relationship between neighborhood context and attitudes toward sex and having babies as part of the PHDCN study.
• Studying longitudinal trends in relationship development and sexual experience across three age cohorts (12, 15, 18).

Strengths

• Data comes from a large-scale, interdisciplinary study following over 6,000 participants.
• Focuses on three specific age cohorts (12, 15, 18) during a defined period (1997-2000).
• Part of a coordinated longitudinal study designed to examine influences on antisocial behavior.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for this specific protocol is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to a single-city study from the late 1990s.
