The association between cognitive coping strategies and treatment outcomes in smokers with PTSD

Numerous researchers have suggested that certain coping styles (e.g., maladaptive cognitive coping strategies) interfere with recovery from traumatic experiences and contribute to the onset/maintenance of posttraumatic stress disorder (PTSD). Further, given that individuals with PTSD have a high rate of smoking (e.g., Mahaffey et al., 2016) and that maladaptive coping strategies in general are associated with lower smoking quit rates, it is possible that use of maladaptive cognitive coping strategies are particularly problematic for the recovery of smokers with PTSD. The present study examined whether specific cognitive coping strategies are associated with poorer outcome among smokers with PTSD following an integrated treatment for both disorders.

Patients with chronic PTSD and nicotine dependence (N = 142) received up to 12 sessions of smoking cessation counseling combined with varenicline or integrated prolonged exposure therapy and cessation counseling combined with varenicline. We hypothesized that greater maladaptive, and lower adaptive, cognitive coping strategies at baseline would moderate degree of improvement in smoking and PTSD outcomes through to follow-up.

Multilevel modeling revealed that neither maladaptive nor adaptive cognitive coping strategies moderated smoking abstinence outcomes over the course of the study (ps ≥ .271). However, greater use of catastrophizing and lower use of positive reappraisal at baseline were associated with less improvement in the hyperarousal PTSD symptom cluster over the course of the study (ps ≤ .01).

These findings suggest that maladaptive cognitive coping strategies are not necessarily a contraindication for overall outcomes in integrated PTSD and smoking treatment, although they may influence improvement in hyperarousal symptoms. (PsycINFO Database Record (c) 2020 APA, all rights reserved).
