This study assessed whether or not the initial attitudes and beliefs of a behaviorally homogeneous group can be used as indicators of future smoking behavior. Ss included seventh graders who classified themselves as never-smokers on an initial survey and who participated in all three surveys over a 2-year period. The initial survey consisted of a 44-item attitude-belief form similar to the Likert form. Ss later classified themselves according to their subsequent smoking behavior as either smoker, ex-smoker or never-smoker. An analysis of variance technique was used to determine whether attitude-belief differences existed among the three groupings. Results indicated that female never-smokers who remained never-smokers had more favorable attitudes toward nonsmoking than those who became smokers or ex-smokers. Significant differences for male data were found on the pleasure, influence, and health disease factors. These results suggest that attitudes and beliefs of initial never-smokers may serve as indicators of future behavior. It appears, also, that items of an affective rather than a cognitive domain are more useful indicators. (Author/JB)
