This self-rating scale is designed to assess the severity and type of symptoms in patients with OCD. Before you begin the test, read the following definitions and examples of “obessions” and “compulsions.”

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 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.

Answer each question based on the average occurrence of each item over the past week. The first 5 questions relate to obsessive thoughts, the last 5 questions relate to compulsive behaviors.

  1. How much of your time is occupied by obsessive thoughts?
  2. How much do your obsessive thoughts interfere with functioning in your social, work, or other roles?
  3. How much distress do your obsessive thoughts cause you?
  4. How much of an effort do you make to resist the obsessive thoughts?
  5. How much control do you have over your obsessive thoughts?
  6. How much time do you spend performing compulsive behaviors?
  7. How much do your compulsive behaviors interfere with functioning in your social, work, or other roles?
  8. How anxious would you become if you were prevented from performing your compulsive behaviors?
  9. How much of an effort do you make to resist the compulsions?
  10. How much control do you have over the compulsions?
