AB  - Impairments in executive functioning have been identified as an underlying cause 
      of Obsessive-Compulsive Disorder (OCD). Obsessive patients attempt to suppress 
      certain unwanted thoughts through a mechanism that Wegner referred to as 'chronic 
      thought suppression', whereas compulsive patients are unable to inhibit their 
      rituals. We tested 51 OCD patients using the Yale-Brown Obsessive Compulsive 
      Scale (Y-BOCS), the White Bear Suppression Inventory (WBSI) and the Dysexecutive 
      Questionnaire (DEX). Executive functions were tested using a cognitive test 
      battery. We found that the total WBSI score was correlated with the Y-BOCS 
      obsessive score but not with the Y-BOCS compulsive score. A stronger correlation 
      was observed between the Y-BOCS obsessive score and the 'unwanted intrusive 
      thoughts' factor based on Blumberg's 3-factor model of the WBSI. The total WBSI 
      score was not correlated with the cognitive test results. The DEX score was 
      significantly correlated with the Y-BOCS compulsive score; however, no 
      correlation was found between the DEX score and the Y-BOCS obsessive score. A 
      stronger correlation was observed between the Y-BOCS compulsive score and the 
      'inhibition' component of the DEX score, as defined by Burgess's 5-factor model. 
      The DEX scores were correlated with cognitive test results measuring attention, 
      cognitive flexibility and inhibitory processes. We conclude that obsessions 
      indicate a failure of cognitive inhibition but do not involve significant 
      impairment of executive functions, whereas compulsions indicate ineffective 
      behavior inhibition and impaired executive functions.
