Is 'stage of change' related to knowledge of health effects and support for tobacco control?
We examine the heterogeneity among current and former smokers categorized by 'stage of change' with respect to their perceptions about tobacco and tobacco control. Current and former smokers (n = 846) from a general population sample of adults in Ontario, Canada, were subdivided according to the stages of change categories (precontemplation, contemplation, preparation, action, maintenance, and termination) and compared on measures of knowledge, attitudes, and support. Multivariate analyses were conducted adjusting for sociodemographic covariates. Adjusted overall increases across the six stages were observed for seven of eight knowledge items and for all attitude and support items. Among current smokers, adjusted increases across the three stages were detected for a majority of items. However, statistically significant differences from one stage to the next, across all three current smoker stages, were detected only for one item. Among former smokers, adjusted increases across the three stages were observed for a minority of items. The stages of change classification was useful for differentiating subgroups of current smokers with regard to knowledge, attitudes, and support for tobacco control measures.
