With a direct link between traumatic stress and poor smoking outcomes established, there is a clinically important need to identify underlying, targetable mechanisms that maintain these relations. The present study employed a parallel mediation model to assess the competing explanatory significance of four distinct facets of depression and anxiety (general anxiety, anxious arousal, general depression, and anhedonic depression) in the relation between traumatic load and perceived barriers for quitting smoking, severity of psychosomatic problems experienced when attempting to quit smoking in the past, and negative reinforcement expectancies related to smoking among 98 adult trauma-exposed daily smokers (M = 44.64, SD = 10.

Recent years have been marked by an increase in electronic cigarette (e-cigarette) use. Although some evidence suggests that e-cigarettes used in isolation may be less harmful than combustible cigarettes, e-cigarette use carries significant health risks. Data are critically needed to identify risk factors that promote and maintain e-cigarette use.

Electronic cigarette (e-cigarette) use has risen exponentially since its initial introduction. The widespread and growing use of these novel products has prompted increased research to evaluate use from a nuanced perspective that considers patterns and antecedents of use. Specifically, research has identified sociodemographic characteristics related to varying levels of e-cigarette use frequency.
