This study is freely available to the general public. Also available as downloadable files. The National Survey of Parents and Youth (NSPY) is a survey conducted to evaluate the National Youth Anti-Drug Media Campaign (Campaign). It focuses on the measurement of the outcomes and impact of Phase III of the Campaign on children and their parents concerning illegal drug use among youth. It contains four rounds of Restricted Use Files and includes all NSPY respondents. The Restricted Use Files also contain extensive data on youth, parents, and the Campaign advertisements, as well as other reference files. In addition, NSPY contains Public Use Files which were released in September 2004. The Public Use Files contain only the first three rounds of data and a subsample of respondents. Also, due to confidentiality reasons, the September 2004 Public Use File provides a limited set of variables about youth, and only a handful of variables about parents as it is not possible to link respondents across rounds using the Public Use Files, but it is possible using the Restricted Use Files. The survey was developed and implemented under contract to the National Institute on Drug Abuse (NIDA). Westat conducted the study in collaboration with the Annenberg School for Communication at the University of Pennsylvania and, for the first two years of the project, with the National Development and Research Institutes, Inc. (NDRI). NSPY Round 1 was conducted in three waves, covering the periods November 1999 through May 2000 (Wave 1), July 2000 through December 2000 (Wave 2), and January 2001 through June 2001 (Wave 3). NSPY Round 2, the first follow-up of the initial survey, was conducted in two waves covering the periods July 2001 through December 2001 (Wave 4) and January 2002 through June 2002 (Wave 5). NSPY Round 3, the second follow-up data collection, was conducted in two waves covering the periods July 2002 through December 2002 (Wave 6) and January 2003 through June 2003 (Wave 7). Finally, NSPY Round 4, the third follow-up data collection, was conducted in two waves covering the periods July 2003 through December 2003 (Wave 8) and January 2004 through June 2004 (Wave 9). Youths and their parents were selected for NSPY through a multistage, dual frame probability sample design. The sample was selected in a manner designed to provide an efficient and representative cross-section of American youth. In general, youths living in all types of residential housing units were eligible for the study; however, youths living in institutions, group homes, or dormitories were excluded.
