title: Preliminary analyses of psychometric characteristics of the Polish version of the Obsessive-Compulsive Inventory-Revised (OCI-R) in a non-clinical sample.
abstract: OBJECTIVE
  Obsessive-compulsive disorder (OCD) is an anxiety-spectrum disorder that affects 1-2% of the adult population. People with OCD are more likely to report impaired social and occupational functioning. Although effective treatments of the OCD exist, many sufferers from this disorder are continuously misdiagnosed. Therefore, improving the assessment of the OCD remains an important area of scientific research. The main goal of the study is the initial verification of psychometric properties in the Polish version of the Obsessive-Compulsive Inventory-Revised (OCI-R) in a college student sample.
  
  
  METHODS
  A group of students completed a battery of measures consisting of obsessive-compulsive symptoms (The OCI-R, The Yale-Brown Obsessive Compulsive Scale), depression (The Beck Depression Inventory) and anxiety trait (The State-Trait Anxiety Inventory).
  
  
  RESULTS
  A confirmatory factor analysis, conducted on data from 334 university students, supported a solid and replicable 6-fold factor structure of the OCI-R. Further analyses on test-retest reliability (following a 1-month interval), convergent and divergent validity of the OCI-R were respectively conducted in a group of 137 students who had completed a battery of measures mentioned above. The results showed adequate testretest reliability for the full scale and subscales cores, high internal consistency and confirmed satisfactory convergent and divergent validity.
  
  
  CONCLUSIONS
  The study constitutes the first phase of work on a Polish version of measurement for obsessive-compulsive symptoms. Satisfactory results obtained in a non-clinical sample allow to recognize this method to be promising for further research. Int J Occup Med Environ Health 2016;29(6):1011-1021.
