ABSTRACT
The Composite International Diagnostic Interview [CIDI] is a comprehensive, standardized diagnostic interview for the assessment of psychiatric disorders. There have been few studies on the validity of the CIDI. The objective of present study was to assess the validity of a Farsi translation of the complete CIDI and its psychosis/mania module in five referral clinical psychiatric settings. Two hundred and three as well as 104 consecutive admissions were interviewed using the complete and the psychosis/mania module, respectively. Within two days of the CIDI interview, two last year residents of psychiatry or psychiatrist who were blind to the CIDI diagnosis completed the Clinical diagnostic checklists [based on DSM-IV and ICD-10 criteria] simultaneously and reached the consensus diagnosis. Data analysis was performed using SPSS 11 to determine the validity of CIDI. The sensitivity and specificity for the diagnosis of schizophrenia was 0.12 and 0.96 using DSM-IV criteria. According to ICD-10 criteria, the results were the same with 0.19% sensitivity and 0.96% specificity. The sensitivity for the diagnosis of bipolar I disorder was low [0.21 using DSM-IV criteria and 0.17% using ICD-10] and specificity, high [0.90 compared to DSM-IV and 0.89 compared to ICD-10 criteria]. The results were rather similar for the psychosis/mania module of CIDI. This study suggests that the Farsi translation of both the complete CIDI and the psychosis/mania module of CIDI have good specificity, but poor sensitivity for the diagnosis of schizophrenia and of bipolar I disorder

This project was conducted to evaluate the rate of comorbidity of Tourette's disorder with obsessive-compulsive disorder [OCD]. All of the patients diagnosed with Tourette's disorder, a total of 20 cases that had been referred to Child Psychiatric Ward of Roozbeh Hospital since its inception were evaluated. They were compared with 20 patients afflicted with attention-deficit hyperactivity disorder, and 20 OCD patients. Data was collected via Yale Tic Severity Scale and analyzed by descriptive statistical methods, Fisher's LSD, and chi[2] statistical test. The mean age of onset of Tourette's disorder was 8.5 years [SD: 0.65] whereas the onset of OCD was 14.5 years [SD: 0.7]. The ratio of male to female in Tourette's disorder was four to one and in OCD, it was two to one. The level of correlation between these two disorders was statistically significant. There was not a significant level of correlation obtained for the presence of co-morbidity of Tourette's and OCD disorders in the immediate family members of the patients. The level of comorbidity of OCD in children afflicted with Tourette's disorder is remarkable
