Vaping motivations Association of behavioral inhibition and behavioral activation systems with nicotine and cannabis vaping among adolescents.
Despite copious information on the hazards of nicotine and cannabis, many adolescents report vaping nicotine and cannabis. To advance knowledge on the precursors of vaping behaviors, this study examined the association of behavioral inhibition system (BIS) and behavioral activation system (BAS) sensitivities with nicotine and cannabis vaping among adolescents. Data were part of a longitudinal survey on substance use and mental health among adolescents and included 2,467 11th grade students from 10 public high schools in California. Participants completed a 20-item scale assessing BIS (one aspect) and BAS (three aspects drive, fun-seeking, reward responsiveness) sensitivities at baseline and reported their past 30-day nicotine and cannabis vaping at baseline and again at 6-month follow-up. Unadjusted and adjusted (controlled for demographic characteristics and product-specific baseline vaping) regression models estimated vaping risk at follow-up by BISBAS scores at baseline. Bivariate analyses showed participants who vaped nicotine had significantly higher drive and fun-seeking scores (p < 0.05) and cannabis vapers had lower BIS and reward responsiveness scores (p < 0.05) compared to non-users. Higher fun seeking scores was associated with increased odds (OR 1.15, 95 %CI 1.03-1.29) of nicotine vaping and higher reward responsiveness scores reduced odds (OR 0.89, 95 %CI 0.79-0.99) of nicotine vaping. Higher scores on BIS was associated with decreased the odds (OR 0.91, 95 %CI 0.84-0.99) of cannabis vaping. Different behavioral motivations should be targeted when developing interventions designed to reduce nicotine and cannabis vaping among diverse adolescents.
