ABSTRACT
INTRODUCTION: Obsessive compulsive disorder is a common disorder, but research on its clinical features is scarce. The goal of this study is to describe the clinical characteristics and demographic features of a large sample of patients with Obsessive compulsive disorder. METHOD: The characteristics of 104 patients who sought psychiatric treatment and who were diagnosed as having Obsessive compulsive disorder were assessed by means of a structured questionnaire. RESULTS: The mean age of onset was 20 years and the mean time before soliciting treatment was 4 years. Most of the patients reported an insidious onset and related the onset to an stressful event. The most frequent obsessions were doubt, aggressiveness and contamination. Checking, need to ask and mental rituals were the most frequent compulsions. Cleaning and repetition compulsions were most frequent in women. DISCUSSION: Our results regarding age at onset of illness, way of onset or prevalence of certain obsessions and compulsions are similar to previous research. No agreement was obtained with previous research regarding the link between stress and illness onset, the course of the disorder or the time before treatment was sought. The differences with respect to previous studies could be accounted for the use of different instruments or criteria. The need for the development of instruments allowing to shed light on these discrepancies is stressed.
