PHDCN: Physical Development Scale for Chicago Youth, Wave 3 (2000-2002)

2000-2002 data from the Project on Human Development in Chicago Neighborhoods (PHDCN) Longitudinal Cohort Study. This wave of the Physical Development Scale is a self-report measure used to ascertain pubertal status for children in three age cohorts. The study was led by Felton J. Earls of Harvard University and followed over 6,000 randomly selected children, adolescents, and young adults.

Use Cases

• Modeling pubertal development trajectories based on self-reported physical development items.
• Analyzing links between pubertal timing and antisocial behaviors within the longitudinal cohort framework.
• Studying neighborhood effects on child and adolescent development using the PHDCN's interdisciplinary measures.

Strengths

• Part of a large-scale longitudinal study following over 6,000 randomly selected participants.
• Data collection occurred over a defined two-year period (2000-2002) for Wave 3.
• Focuses on three specific age cohorts (6, 9, and 12), allowing for developmental comparisons.

Limitations

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