Outcome expectations and use of smokeless tobacco (snus): a cross-sectional study among young Norwegian snus users.
In this study, measures of outcome expectancies related to use of snus (wet snuff) were used to predict reported frequency of snus use. Data stem from a nation-wide survey in Norway among 16- to 20-year-olds. Only users of snus were included in the statistical analyses (n = 589). The main outcome measure, frequency of snus use, was measured as a categorical variable - occasional, weekly and daily use. Four dimensions of outcome expectancies (mood regulation, smoking control, weight control and negative health outcomes) were measured and confirmed in a confirmatory factor analysis. Informants tended to believe that snus use is harmful to health, but still they supported the idea of snus as a way to control own cigarette smoking. In a SEM model, two of the four dimensions of outcome expectancies turned out to be particularly significant predictors of frequency of snus use - mood regulation and smoking control. No significant interactions with gender were found. Males scored higher than females on "mood regulation", and "smoking control", while females scored higher than males on "negative health outcomes". If more smokers were convinced that snus use is a less harmful alternative, more of them might start using snus, not only because there is some association between health outcome expectancies and snus use, but also because snus use by many is perceived as a remedy to stop smoking and as a way to gain some of the mood regulation benefits which are usually associated with smoking.
