As opposed to other psychiatric populations, subjects with obsessive-compul
sive disorder (OCD) smoke less than the general population. The present stu
dy aims at further investigating the relationship between smoking in OCD su
bjects and personality traits.
Sixty-four subjects with OCD were interviewed concerning their smoking habi
ts. Personality traits were evaluated using the Karolinska Scales of Person
ality, and specific obsessive-compulsive personality traits were elicited t
hrough self-report questionnaires.
Non-smokers were more easily fatigued, more inclined to worry, more remorse
ful, less self-confident, less impulsive and became uneasy more frequently
when urged to speed up, than smokers with OCD. Additionally, non-smokers fu
lfilled significantly more obsessive-compulsive personality disorder criter
ia as compared to the smokers (P < 0.001).
We propose a clinical subtype of OCD related to non-smoking, psychasthenia,
anxiety, and pronounced obsessive-compulsive personality disorder traits.
