Abstract:
|
Through the National Household Survey on Drug Abuse (the predecessor of the current National Survey on Drug Use and Health), we calculated intraclass correlations (IC) for both cognitive and behavioral measures on drug use at the census tract and census block group levels within six major metropolitan areas respectively. We demonstrate that IC should not be overlooked in the substance abuse fields and discuss further the utility of empirical knowledge of intraclass correlations of pertinent measures in future sample design, estimations, and for policy oriented preventions and interventions.
