مقایسه آزمون وسواسی- اجباری مادزلی و مصاحبه بالینی ساختاریافته مبتنی بر DSM-IV برای تشخیص اختلال وسواسی- اجباری در بیماران مبتلا به اسکیزوفرنیا

 AbstractObjectives: This study plans to determine diagnostic features and the best cut-off point in Maudsley Obsessive-Compulsive Inventory for patients with schizophrenia. Method: In a cross-sectional study, 96 inpatients (56 men and 40 women) with schizophrenia (based on DSM-IV diagnostic criteria) were selected from Iran Psychiatry Hospital (in Tehran) by convenient sampling and screened for Obsessive-Compulsive Disorder using standard clinical interview (SCID) and Maudsley Inventory. Results: Based on the clinical interview, 47 patients (49%) were diagnosed to have obsessive-compulsive symptoms. In the Maudsley Inventory, 38 patients (40%) scored above the given cut-off point (score of 9). The sensitivity and specificity of the Maudsley Inventory were 74.5% and 93.9% respectively. Conclusion: Despite the high specificity of Maudsley Inventory, the clinical interview is preferred over it because of higher sensitivity and the number of true-positive diagnoses.
