Note: NSDUH: the National Survey on Drug Use and Health, NLSY97: the National Longitudinal Survey of Youth 1997. The cross-sectional 1997 NSDUH data were used for estimating probabilities of smoking behavior transitions with the Probabilistic Discrete Event System (PDES) method; the longitudinal NLSY97 data with baseline data collected in 1997 and followed up data collected in 1998 were used to estimate transitional probabilities for the same smoking behavior transitions; and a comparison of the two sets of transitions provided evidence assessing the validity of the PDES method. The 10-year NSDUH data were used to estimate smoking behavior transitions for US youth 12-17 years of age by the validated PDES method.
