use, knowledge, beliefs, and attitudes related to tobacco among the target population and the population at large before the beginning of the programme. Meister and Clift asked a consortium of the three public universities in Arizona to collaborate in a comprehensive project for both baseline and ongoing evaluation. 79 The plan developed by the consortium had a cost higher than the administration was willing to pay and it was not accepted. Further, top levels of the administration stated that they were interested only in prevalence of tobacco use. 79 There were some data available through a Department of Justice juvenile survey and through Arizona's Behavioural Risk Factor Survey (BRFS), conducted in collaboration with the federal Centers for Disease Control and Prevention (CDC). ADHS did not consider the data adequate to answer programme evaluation questions -- it wanted a specific survey about the knowledge, behaviour, and attitudes of Arizonans regarding tobacco use and tobacco control measures, such as clean indoor air and youth access policies. In addition, ADHS wanted a sample that would be demonstrative of the state's five regions, so local projects could use the results in planning their activities. 97 A baseline survey was initiated in April 1996, by the epidemiology division of ADHS. It is a comprehensive adult and youth survey, with a large enough sample (6000 adults and 6000 young people aged 10 -- 17 years) to provide detailed information by region as well as to detect small changes longitudinally. The survey addresses issues related to behaviour,
