Abstract

Introduction: The present investigation examined the main and interactive effects of posttraumatic stress symptom severity and 12-hr cigarette deprivation (cf. smoking as usual) in the prediction of anxious responding during a 4-min 10% carbon dioxide (CO2)-enriched air laboratory challenge. It was hypothesized that 12-hr cigarette deprivation would exacerbate the effects of posttraumatic stress symptom severity with regard to anxious responding during the challenge. Methods: Participants were 63 daily smokers (46.0% women; Mage = 30.79, SD = 13.12, range = 18-60) who reported experiencing one or more traumatic events. The study consisted of two laboratory sessions. At the first session, participants were administered a structured diagnostic interview and completed self-reported measures. Eligible participants were randomly assigned to one of two conditions for the second session: (a) 12-hr cigarette deprivation or (b) noncigarette deprivation (i.e., smoking as usual). At the second session, participants' smoking status was biochemically verified, and all eligible participants then were administered the 10% CO2-enriched air laboratory challenge protocol. Results: The main and interactive effects of posttraumatic stress symptom severity and the smoking-as-usual condition-not the hypothesized 12-hr cigarette deprivation condition-were significantly predictive of peri-challenge anxiety. The interactive effect of posttraumatic stress by smoking as usual was significant at Minutes 3 and 4 of the challenge specifically. Conclusions: The present investigation provided novel findings related to the roles of cigarette deprivation and smoking with regard to self-reported anxious responding, among trauma-exposed smokers, during a challenge paradigm.
