The objective of this study was to examine the association between anxiety sensitivity (AS) and substance use, and to explore the moderating and mediating effects of social anxiety and outcome expectancies. The results showed a negative association between AS and drinking game and pregaming participation, but no direct association with other substance use outcomes. The association between AS and hazardous cannabis use was moderated by outcome expectancies, while social anxiety mediated the associations between AS and hazardous cannabis use, as well as drinking game and pregaming participation.
Objective: Research on the association between anxiety sensitivity (AS) and substance use is mixed, with some studies showing a positive association and others showing no association. Other relevant variables, such as social anxiety and outcome expectancies, may help us understand how and for whom AS is linked to substance use. This study tested (a) the associations between AS and alcohol use, cannabis use, and drinking games and pregaming behaviors among young adults, and (b) the mediating role of social anxiety and moderating role of outcome expectancies in these associations. Method: Participants (N = 199, 69% women) were young adults (19 to 25 years) who completed a 30-minute online self-report questionnaire on their substance use. Results: Results revealed significant negative associations between AS and drinking game and pregaming participation. AS was not directly associated with other substance use outcomes. The association between AS and hazardous cannabis use was moderated by relaxation and tension reduction expectancies, but outcome expectancies did not moderate any of the other associations between AS and substance use outcomes. Social anxiety mediated the associations between AS and hazardous cannabis use and both drinking game and pregaming participation. Conclusions: Findings highlight the complex association between AS and different substance use outcomes. Outcome expectancies and social anxiety may help explain how AS is associated with hazardous cannabis use and drinking game/pregaming participation, respectively. More effective interventions can be developed by understanding the relation between AS and substance use.
