Methods: The sample consisted of 52 OCD patients, 32 non-OCD patients with other anxiety disorders, 36 nonobsessional depressed patients, 75 healthy adults, and 278 undergraduate students. We investigated internal consistency, test-retest reliability, concurrent and discriminant validity of the instrument. Results: Cronbach's α coefficients for the CBOCI Obsessions, Compulsions and Total scale were found as 0.86, 0.83 and 0.91 in all samples respectively. The CBOCI obsessions (r=0.81, p<0.001), compulsions (r=0.85, p<0.001) and total score (r=0.85, p<0.001) showed a significant level of temporal stability. OCD patients scored significantly higher on CBOCI obsessions, compulsions and total scale than non-obsessional anxious, depressed patients, healthy control subjects. Obsession, compulsion and total scores of both OCD and nonclinical sample were significantly correlated with other scales assessing obsessive compulsive symptoms. Discussion: The Turkish version of the CBOCI has appropriate reliability and validity for assessing the frequency and severity of obsessive-compulsive symptoms.trinfo:eu-repo/semantics/closedAccessClark-Beck Obsessive-Compulsive InventoryObsessive Compulsive DisorderReliabilityValidityArticle83Q4Q3197205
