Abstract:

The 2002 National Youth Tobacco Survey (NYTS) was conducted by RTI and ORC Macro. The NYTS is sponsored by the American Legacy Foundation and the Centers for Disease Control and Prevention. It included two sample components: 1) a panel sample including schools subsampled from the 2000 NYTS sample, and 2) a fresh independent sample. The sample design included new stratification information related to local area exposure to "truth," a tobacco countermarketing media campaign, as well as the regional stratification used in the 2000 NYTS design. The new independent sample was selected with a multistage stratified sampling design using probabilities proportional to size for selecting PSUs and schools, similar to the 2000 NYTS design. This paper focuses on issues related to weighting the two samples as well as the combined sample. We consider variations of a method based on linear combinations of the two sets of weights with alternative ways of computing the coefficients for the weights.
