Study of psychotic symptoms pattern in patients with obsessive compulsive disorder

Abstract

Obsessive compulsive disorder (OCD) is associated with heterogeneous and various symptoms. Sometimes it is easy to diagnose, such as the washing and checking of obsessive compulsive disorder, but some patients exhibit psychotic symptoms that make it difficult to diagnose psychosis, including schizophrenia. Therefore, this study was conducted to examine the pattern of psychotic symptoms in patients with obsessive-compulsive disorder. Methods: One hundred eighty five patients who had OCD diagnostic criteria, DSM 5, were selected. The severity of the disease and the level of insight measured by the scale of Yale Brown and the pattern of psychotic symptoms measured by the scale of the positive and negative symptoms and demographic characteristics with a questionnaire and the frequency of psychotic symptoms. The results were analyzed using SPSS software. Results: 38 patients (20.5%) had psychotic symptoms. The incidence of psychotic symptoms was significantly higher in men, patients at the age of 18-30, the level of education under the diploma and single subjects (P <0.05). All patients with psychotic symptoms lacked insight. In patients with psychotic symptoms, mean score of Yale-brown was 26.42±5.7 and 26.24±6.38 in patients without psychotic symptoms; that was significantly higher in patients with psychotic symptoms (P = 0.029). The mean of the onset duration in patients with psychotic symptoms was 4.42±4.31 years.
