Sibling Similarity for Problem Behavior in the National Youth Survey From Adolescence to adulthood

Robin Corley, University of Colorado at Boulder

The foundation sample of the National Youth Survey (NYS) consisted of 1725 individuals drawn from 1044 households, with 574 households represented by only a single individual, and the remaining 470 households represented by at least two individuals. the sibling relationships in the NYS sample have been used previously (e.g., Rowe & Britt, 1991, Journal of Quantitative Criminology, 7:315-331), but are central to the extension of the National Youth survey to a three-generation family study of problem behavior. we review the sibling resemblance for self-reported substance and delinquent problem behaviors from adolescence to young adulthood, and compare these results to those obtained from unselected, genetically informative samples of twin, adopted siblings, and full siblings from Colorado tested as adolescents and yount adults.
