Differential Effects of Anxiety Sensitivity on E-Cigarettes Processes: The Importance of E-Cigarette Quit Attempt...

Electronic cigarettes (e-cigarettes) are recognized as a prevalent form of substance use among adults in the United States. The rise in e-cigarette use has motivated research to identify subgroups of the population that may be particularly vulnerable to e-cigarette use and its associated harm. Individuals with elevated psychological vulnerability are one such group more at risk for being a lifetime or current e-cigarette user. Yet, little is known about how factors of psychological vulnerability relate to perceptions of e-cigarette use within the context of e-cigarette quit attempts. The current study evaluated the differential relations of anxiety sensitivity (AS), a core affective vulnerability factor, on several relevant e-cigarette processes across those with and without a previous attempt to quit using e-cigarettes.

Our sample consisted of 547 current e-cigarette users (51% female, M_age  = 35.38 years, SD = 10.1).

Results indicated that AS significantly related to greater perceived risks, benefits, and positive outcome expectancies of e-cigarette use among current e-cigarette users who reported at least one attempt to quit e-cigarettes but was unrelated among those who had never attempted to quit.

Findings identify e-cigarette users who fail to quit as a potential vulnerable subgroup of users who experience more strongly held perceptions about e-cigarettes because of increased AS.

This work provides initial evidence for a conceptual model in which levels of AS and e-cigarette processes are strengthened by and differ across e-cigarette quit attempt history. (Am J Addict 2019;28:390-397).
