Relations between pain-related anxiety, tobacco dependence, and barriers to quitting among a community-based sample of daily smokers.

There is increasing recognition that complex and potentially bidirectional relations between pain and smoking may be relevant to the maintenance of tobacco addiction. Pain-related anxiety has been identified as a mechanism in the onset and progression of painful disorders, and initial evidence indicates that pain-related anxiety may be associated with essential features of tobacco dependence among smokers with chronic pain. However, there has not been an empirical study of pain-related anxiety in relation to tobacco dependence and self-reported barriers to quitting among a community-based sample of daily smokers. The current sample was comprised of 122 daily smokers who were recruited from the local community to participate in a larger study that included an initial assessment of pain, smoking history, and pain-related anxiety. Approximately 17% of our sample endorsed moderate or severe past-month pain, nearly half met criteria for current anxiety or mood disorder, and about 30% met criteria for a current substance use disorder, exclusive of tobacco dependence. Results indicated that pain-related anxiety was uniquely and positively associated with both tobacco dependence severity scores and self-reported barriers to quitting. These findings lend support to the notion that pain-related anxiety may contribute to the maintenance of tobacco addiction among smokers who experience varying levels of pain severity.
