title: Relationship between impulsivity and obsession types in obsessive-compulsive disorder.
abstract: OBJECTIVE
  Impulsivity is an important aspect of obsessive-compulsive disorder (OCD) which is classified under a new heading in DSM-5 with other impulsivity related disorders like trichotillomania. Due to its heterogeneous nature, different obsessions may be linked to varying impulsivity profiles. Aim of this study was to investigate the impulsivity traits and their relationship with obsession types by comparing OCD subjects who display sexual, religious and aggressive obsessions or other obsessions to healthy controls.
  
  
  METHODS
  Outpatients with OCD (n = 146) and healthy controls (n = 80) were evaluated with Sociodemographic Data Form, SCID-I, SCID non-patient version, Yale-Brown Obsessive Compulsive Scale (Y-BOCS) and Barratt Impulsiveness Scale (BIS-11).
  
  
  RESULTS
  BIS-11 attention scores of the OCD group were significantly higher than healthy subjects. In patients with sexual, aggressive, religious obsessions, BIS-11 attention scores were significantly higher than those who have other obsession types and that of controls.
  
  
  CONCLUSIONS
  Higher levels of attentional impulsivity, particularly in patients suffering from sexual, aggressive or religious obsessions suggest a common diathesis for a dysfunction in neural correlates corresponding to these symptoms. The results of our study may promote further studies conducted with more advanced and objective neuropsychometric tests evaluating features of the clinical course, neurobiology and the response to OCD treatment.
