PHDCN: Generalized Anxiety Disorder in Chicago Youth, 1997-2000

Generalized Anxiety Disorder data from the Project on Human Development in Chicago Neighborhoods (PHDCN) Longitudinal Cohort Study. The study followed over 6,000 randomly selected children, adolescents, and young adults to examine influences on antisocial behavior. This subject-level instrument, adapted from the Diagnostic Interview Schedule for Children (DISC 4), was administered to Cohorts 9, 12, and 15 during Wave 2 (1997-2000) and obtained information regarding subjects' worrying and anxiety.

Use Cases

• Modeling risk factors for anxiety based on longitudinal cohort data mentioned in the description
• Analyzing the relationship between neighborhood context and mental health outcomes based on the study's interdisciplinary focus
• Training classifiers to identify anxiety symptoms based on instrument responses about worrying and anxiety

Strengths

• Data originates from a large-scale, interdisciplinary study following over 6,000 participants
• Longitudinal design tracks subjects and primary caregivers over time
• Instrument is adapted from a standardized diagnostic tool (DISC 4)

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count for this specific instrument is unknown, which may limit suitability assessment
• Data may reflect geographic and temporal bias inherent to a single-city study from 1997-2000
