YBOCS v.1

Yale-Brown obsessive compulsive scale (Y-BOCS) is a 10-item self-reported questionnaire used to assess the severity of symptoms, as well as monitor treatment improvement in patients with obsessive compulsive disorder (OCD). 5 items measure obsessions and 5 items measure compulsions, all in terms of the time occupied, how much they interfere with functioning, the patient’s degree of distress, and his or her attempts to resist symptoms and the ability to control them successfully. Each item is rated 0 = no symptoms to 4 = extreme symptoms, yielding a minimum possible score = 0 and a maximum possible score = 40.

To assess the severity of symptoms in patients with OCD, irrespective of the type of obsessions or compulsions. Based on symptoms in the prior one week.

To calculate the Y-BOCS score for determining severity of obsessions and compulsions in patients with obsessive compulsive disorder, based on the average occurence of each item over the past week. The scale consists of 10-items (5 items related to obsessions and 5 items related to compulsons) each rated from 0 = no symptoms to 4 = extreme symptoms, yielding a minimum score = 0 and a maximum score = 40. Should preferrably be used along with the \"Y-BOCS symptom checker\" which lists specific target symptoms and helps ensure consistency in symptom reporting. Also used to monitor improvement and treatment outcome in patients with obsessive compulsive disorder. \"Obsessions are unwelcome or distressing ideas, thoughts, images or impulses that repeatedly enter your mind. They may seem to occur against your will. They may be repugnant to you, are often senseless, and may not fit your actual personality at all (for example, the recurrent thought or impulse to do harm to your children, even though you never would). Compulsions are behaviors or acts that you feel driven to perform, even though you may recognize them as senseless or excessive. At times, you may try to resist doing them, but this may prove difficult. You may experience anxiety that does not diminish until the behavior is completed.\"

Result is not reliable if the validity of the patient's responses are in doubt.
