title: The relationship between insight and uncertainty in obsessive-compulsive disorder.
abstract: BACKGROUND
  The aim of this study was to investigate the relationship between the levels of insight and checking-related uncertainty in patients with obsessive-compulsive disorder (OCD).
  
  
  METHODS
  Twenty OCD patients with checking compulsions and without current comorbidity were recruited. We used an experimental paradigm that gave subjects the opportunity to check during a decision-making task, thereby allowing for the calculation of a response time index (RTI) as the 'uncertainty cost' during decision-making. The level of insight was assessed with the Brown Assessment of Beliefs Scale (BABS).
  
  
  RESULTS
  Regression analyses indicated a significant positive correlation between RTI and BABS scores (r = 0.49).
  
  
  CONCLUSIONS
  The level of insight is related to cognitive characteristics underlying OCD symptoms, in particular, checking-related uncertainty in checking OCD patients.
  
  
  CONCLUSIONS
  The absence of a comparison group and the low number of included patients are the main limitations of the present study.
