Posttraumatic Stress Symptoms and Cognitive-Based Smoking Processes Among Trauma-Exposed, Treatment-Seeking Smokers: The Role of Dysphoria

摘要

Objectives: Despite the co-occurrence and clinically significant relationship between trauma exposure and smoking, there is little understanding of the mechanisms underlying the posttraumatic stress symptoms-smoking relationship. This study examined whether dysphoria (ie, a psychopathologic symptom dimension that reflects depression's core affective, cognitive, and psychomotor features) accounted for the covariance between posttraumatic stress symptom severity and an array of smoking processes among trauma-exposed daily smokers.
