No effects of smoking on positive mood self-report were found in the present study. This is not surprising given positive mood’s somewhat secondary role as an antecedent for smoking in many models of nicotine dependence. Moreover, as Watson et al. (1988) and others have proposed, negative and positive moods are more accurately assessed with independent scales, as they were in the current study. If one views negative mood scales and positive mood scales as capturing separate, but only modestly correlated, mood states, then positive mood findings can easily fail to track negative mood effects.
