“…Impulsivity is a multi-dimensional construct, likely composed of five separate, although related, impulsive traits (Whiteside & Lynam, 2001), which map onto three latent factors (Cyders & Smith, 2007; Cyders et al, 2014): 1) urgency , which is comprised of negative urgency , or a disposition to act rashly in response to negative affect, and positive urgency , or a disposition to act rashly in response to positive affect, 2) deficits in conscientiousness , which is comprised of lack of perseverance , or difficulties seeing tasks through completion, and lack of premeditation , or acting before thinking, and 3) sensation seeking , or seeking out novel and/or exciting experiences. These traits have shown differential relationships with smoking behaviors (Lee et al, 2015), with urgency being the strongest predictor of cigarette use, above and beyond other impulsive personality traits (Lee et al, 2015; Pang et al, 2014). Although no work has examined how e-cig use is related to the above-described factors, some recent work suggests that sensation seeking is related to e-cig use (Cohn et al, 2015).…”
