Main and Interactive Effects of E-Cigarette Use Health Literacy and Anxiety Sensitivity In Terms Of E-Cigarette Perceptions and Dependence.

Income, years of education, and e-cigarette dependence were significant predictors of perceived benefits of e-cigarette use and perceived risks of e-cigarette use in step one of the regression models, and accounted for a significant amount of variance in both models (p <0.001). With the addition of e-cigarette health literacy and AS, step two accounted for significantly more variance in perceived benefits and risks of e-cigarette use (p < .001). There was a significant main effect for e-cigarette health literacy and AS, as well as significant interaction for the terms. E-Cigarette health literacy was related to greater perceived benefits and risks of e-cigarette use among e-cigarette use with higher AS (p < .001); the association was non-significant for those with lower AS.
Dual use was a significant predictor of e-cigarette dependence and accounted for a significant amount of variance in the first model step (p <0.001). With the addition of e-cigarette health literacy and AS, step two accounted for significantly more variance in e-cigarette dependence (p <0.001). There was a significant main effect for e-cigarette health literacy and AS, as well as significant interaction for the terms. E-Cigarette health literacy was related to greater e-cigarette dependence among e-cigarette use with higher AS (p <0.001) relative to those with lower AS. The authors concluded that the current findings suggested that "individual differences in e-cigarette health literacy and AS may represent two important, yet thus far unrecognized, anxiety-related cognitive-based factors to consider in better understanding e-cigarette beliefs and dependence" (p. 128).
