Abstract
Background: Obsessive-compulsive disorder (OCD) has distinct symptom dimensions with possibly subtle differences in the
underlying neurobiology. One behavioral habit, smoking, has been widely investigated in psychiatric disorders, though received less
attention in OCD. Here, we aimed to investigate the relationship between symptom dimensions and smoking behavior in OCD.
Subjects and methods: OCD patients (n=167) with the symptom dimensions of washing, taboo thoughts and symmetry-countingrepeating-
ordering (S+C+R+O) were questioned in terms of smoking status and assessed with the Yale-Brown Obsessive
Compulsive Scale (Y-BOCS), Fagerström Test for Nicotine Dependence (FTND), Hamilton Depression Rating Scale-17 Items
(HDRS-17), Beck Anxiety Inventory (BAI) and Barratt Impulsiveness Scale-11 (BIS 11).
Results: Smoking status differed significantly among patients with distinct symptom dimensions (p=0.009).The ratio of smokers
was the lowest in those with the washing (30%, N=12) and the highest in the S+C+R+O (68.2%, N=15) group. Those with taboo
thoughts had a smoking ratio of 37.14% (N=39). In post hoc analysis, smoking ratio was significantly higher in the S+C+R+O
group than in those with washing symptoms (p=0,004) and taboo thoughts (p=0,007) though it did not differ significantly between
washers and taboo thought groups. The BIS-11 did not differ across symptom dimensions.
Conclusions: OCD is a heterogeneous disorder in terms of smoking. Impulsiveness, which does not significantly vary across
distinct symptom dimensions, cannot explain this heterogeneity. The severity of addiction does not differ in smokers with OCD across
symptom dimensions.
