ONDCP Media Campaign: Contractor's National Evaluation Did Not Find That the Youth Anti-Drug Media Campaign Was Effective in Reducing Youth Drug Use GAO-06-818, Youth Anti-Drug Media Campaign, Washington DC, August 25, 2006. Also: http://www.gao.gov/docsearch/abstract.php?rptno=GAO-06-818 Cohort(s): NLS General, NLSY79 Publisher: Government Accountability Office (GAO), since July 2004 Keyword(s): Dual-Career Families; Substance Use Permission to reprint the abstract has not been received from the publisher. GAO's review of Westat's evaluation reports and associated documentation leads to the conclusion that the evaluation provides credible evidence that the campaign was not effective in reducing youth drug use, either during the entire period of the campaign or during the period from 2002 to 2004 when the campaign was redirected and focused on marijuana use. By collecting longitudinal data--i.e., multiple observations on the same persons over time--using generally accepted and appropriate sampling and analytic techniques, and establishing reliable methods for measuring campaign exposure, Westat was able to produce credible evidence to support its findings about the relationship between exposure to campaign advertisements and both drug use and intermediate outcomes. In particular, Westat was able to demonstrate that its sample was not biased despite sample coverage losses, maintained high follow-up response rates of sampled individuals to provide for robust longitudinal analysis, established measures of exposure that could detect changes in outcomes on the order of magnitude that ONDCP expected for the campaign and that could reliably measure outcomes, and used sophisticated statistical methods to isolate causal effects of the campaign. |
