abstract
Little is understood about individual difference factors related to e-cigarette expectancies about use. This study examined the interactive effects of fatigue severity and anxiety sensitivity in relation to e-cigarette expectancies among 525 e-cigarette users (51.0% female, Mage=35.25years, standard deviation=10.10). Results indicated a significant interaction between fatigue severity and anxiety sensitivity in terms of positive expectancies (=0.57, p<0.001, 95% confidence interval=(0.002, 0.01)), but not for negative expectancies (=0.25, p=0.08, 95% confidence interval = (0, 0.005)) for e-cigarette use. These results support anxiety sensitivity as a moderator in the relation between fatigue severity and positive outcome expectancies for e-cigarette use.
