The mail questionnaire sent to these teens included only a sub-set of questions from the CATI questionnaire. Questions selected for the mail questionnaire included measures for prevalence and some of the more important predictors of smoking uptake. The first section of the tape contains socioeconomic and demographic data from the NHIS and the TAPS and beginning with location 51, subject related data on adolescent tobacco use. Variables for weighing and methodological use begin with location 316. In most instances the organization of data fields on the tape corresponds to the order of data items on the CATI questionnaire.
Exceptions occur when data items have been deleted or recodes of data items have been inserted.
Appropriate weights have been created that attempt to adjust for estimation errors due to missing data items for mail respondents.
