Teacher-Rating As Predictor Of Effect Of A Smoking Prevention ProgramOla Joesendal Research Center for Health Promotion, Oisteinsgate 3, 5007 Bergen, Norway (Research fellow at the Norwegian Cancer Society)PurposeTeachers responsible for presenting a smoking prevention curriculum consisting of eight lessons in 7.th grade, have rated each lesson immediately after finishing the lesson. Rating is obtained through a questionnaire. Teacher ratings in different intervention groups will be related to smoking prevention effects. MethodsThe Norwegian Cancer Society is responsible for a smoking-prevention intervention in Norwegian secondary schools. A country-representative random sample of 99 schools (every 11.tff Norwegian secondary school) participates in the study, with a total of 195 classes and 4.441 students. Schools are systematically allocated to one of four groups: Group A: Control. Group B: Intervention, containing classroom program, parental involving and teacher-courses. Group C' Like B, but without teacher-courses. Group D: Like B, but without parental involvement. Data on smoking frequencies are obtained from baseline survey and first follow-up survey. Data on teacher ratings are obtained from questionnaires in the teacher survey in groups B, C amd D, as described above. ResultsResults will be presented using bivariate correlations between teacher ratings and effect on recruitment of smokers. Preliminary results using school as unit of analysis indicate a weak relation. Results using class as unit of analysis will be presented DiscussionResults will be discussed in light of different statistical methods relevant for multilevel models.
