[Evaluation of imprinting pattern in patients with obsessive- compulsive disorder [OCD] in Sanandaj]

ABSTRACT

Obsessive-compulsive disorder is [OCD] one of the serious problems which imposes high economic and social expenses on the society. The aim of this study was to identify a probable transmission pattern in the families of the patients with OCD. This cross sectional study included 150 patients in the psychiatric centers in Sanandaj. Diagnosis of the disorder was confirmed by a psychiatrist. History of signs and symptoms of OCD in the maternal and paternal relatives of the patients, including the type, severity and duration of the signs and symptoms were recorded in a questionnaire for every patient. We used descriptive statistics to determine relative and absolute frequencies, and chi-square test to analyze the relationship among the nominal variables. The results of this study showed that contamination and pathological doubt were the most frequent patterns. Washing was the most frequent pattern of obsession which was observed in 42% of the patients. The family history of OCD were18% in paternal and 44.7% in maternal relatives. 35.3% of the patients had no family history of OCD. The results indicated that family history of OCD, especially maternal, is important and OCD is more likely to occur in the subjects with family history of this disorder. However more studies are needed to identify the exact genetic pattern
