Peer reviewedLestina, Diane C.; Greene, Michael; Voas, Robert B.; Wells, Joann – Evaluation Review, 1999
Describes the multistage sampling system used in the 1996 national roadside survey of driver blood alcohol and compares it to the sampling methods used in prior surveys in 1973 and 1986. Although many more drivers were sampled in the most recent survey, the procedures are similar enough to allow comparison of results. (SLD)

Results from a study of youth attitudes related to the California Conservation Corps involving 528 participants and 668 comparisons indicate that the comparison group may not adequately represent the nontreatment state.
