    Abstract:
    INTRODUCTION: Posttraumatic stress disorder (PTSD) is associated with various aspects of cigarette smoking, including higher levels of nicotine dependence and cessation difficulties. Affect-regulatory smoking motives are thought to, in part, underlie the association between emotional disorders such as PTSD and smoking maintenance, although few studies have empirically tested this possibility. METHODS: Data were analyzed from 135 treatment-seeking smokers who were directly exposed to the World Trade Center disaster on September 11, 2001. We modeled the direct effect of 9/11 PTSD symptom severity on nicotine dependence, perceived barriers to smoking cessation, and severity of problematic symptoms experienced during prior cessation attempts. We also examined the indirect effect of PTSD on these outcomes via negative affect reduction smoking motives. Parallel models were constructed for additional emotional disorder symptoms, including panic and depressive symptoms. RESULTS: PTSD symptom severity was associated with nicotine dependence and perceived barriers to cessation, but not problems during prior quit attempts indirectly via negative affect reduction smoking motives. Panic and depressive symptoms both had significant indirect effects, via negative affect reduction smoking motives, on all three criterion variables. CONCLUSIONS: Affect-regulatory smoking motives appear to underlie associations between the symptoms of emotional disorders such as PTSD, panic, and depression in terms of smoking dependence and certain cessation-related criterion variables. IMPLICATIONS: Overall, this investigation suggests negative affect reduction smoking motives help to explain the relationship of PTSD, depression, and panic symptoms to nicotine dependence, severity of problems experienced during prior quit attempts and perceived barriers to cessation. These results highlight the importance of assessing motivations for smoking in the context of cessation treatment, especially among those with emotional disorder symptoms. Future interventions might seek to utilize motivational interviewing and cognitive restructuring techniques to address coping-oriented motives for smoking, in addition to skills for managing negative affect, as a means of improving quit outcomes.
