E-Cigarette Use: The Effects of Psychological Vulnerabilities, Perceptions, and Intentions to Use E-Cigarettes.

Little research has examined the effects that psychological vulnerabilities (i.e., difficulty with emotion regulation, depressed mood, distress tolerance) have on the perceptions of e-cigarettes, intent to use e-cigarettes, and actual e-cigarette use. Data were collected via an online survey from 837 adults (55.6% male, = 29.2, 71.7% Caucasian). The two path analytic models predicting lifetime and current use fit the data well. Difficulty with emotion regulation was positively associated with depressed mood and negatively associated with distress tolerance, while distress tolerance was negatively associated with depressed mood. Depressed mood was positively associated with perceived benefits of e-cigarette use, and perceived benefits was positively associated with intent to use. Perceived benefits and intent to use were significantly associated with both lifetime and current use. Findings enhance our understanding of the effects that mood and emotion-related factors have on perceptions of, intent to use, and actual use of e-cigarettes, which may have important implications for prevention and cessation.
