Abstract

Understanding the characteristics of research participants who provide DNA is crucial to ensuring sample representativeness and generalizability of findings of genetics studies of substance use disorders. Using anonymous survey data, the present study had a unique opportunity to compare participants who provided DNA (n=2,414) with those that did not provide DNA (n=1,515). The present study found numerous differences between groups across demographic, substance use, and personality domains. Using multivariate regression, the most parsimonious model found that being male, a non-smoker, and endorsing perseverance was associated with providing DNA. The present study provides benchmark data on sample representativeness in a genome wide association study.
