Tobacco addiction and obsessive-compulsive symptoms (OCS; intrusive thoughts or impulses that cause distress and rituals) are both mediated by compulsivity and negative reinforcement. Little evidence exists to guide theory, research, treatment, and population-based prevention of this co-occurrence. We propose a conceptual model of OCS-smoking co-occurrence in which smokers with elevated OCS capitalize on smoking to assuage OCS. This secondary analysis examined associations between OCS levels and self-reported smoking motives that are model-concordant: i) negative reinforcement-smoking for relief; ii) sensorimotor-benefits of behaviors and sensations of the tobacco self-administration ritual; and iii) habitual-smoking without conscious control. A community sample of cigarette smokers enrolled in a cessation trial (N = 458; 47.2% female; M-age = 36.9; SD = 13.6) completed pre-quit self-report measures of OCS levels and smoking motives. Regression models adjusted for sociodemographic covariates and non-OCS psychopathologies indicated that OCS level was positively associated with each model-concordant motive. OCS level was also correlated with tobacco dependence severity and greater withdrawal symptom severity experienced during previous quit attempts. Those with higher OCS report greater motivation to smoke for negative reinforcement, sensorimotor behavioral-ritualistic, habit/automaticity, and stimulation reasons. Further examination of the proposed model of OCS-smoking co-occurrence is warranted to guide theory and intervention for this population.
