  • Before proceeding with the questions, please read the definitions below to familiarize yourself with "obsessions" and "compulsions".

    OBSESSIONS are unwelcome and 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, you may recognize them as senseless, and they may not fit your personality.

    COMPULSIONS, on the other hand, are behaviors or acts that you feel driven to perform although 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. Examples of obsessions include: the recurrent thought or impulse to apologize for some perceived wrong, or to do serious physical harm to another person even though you never would. Examples of compulsions include: the need to repeatedly check appliances, the lock on the door, or check the internet for symptoms of a perceived illness. While most compulsions are observable behaviors, some are unobservable mental acts, such as silent checking or having to recite nonsense phrases to yourself each time you have a bad thought.
