Each of the following questions asks you about things or “habits” you feel you have to do although you may know that they do not make sense. Sometimes, you may try to stop from doing them but this might not be possible. You might feel worried or angry or frustrated until you have finished what you have to do. An example of a habit like this may be the need to wash your hands over and over again even though they are not really dirty, or the need to count up to a special number (e.g. 6 or 10) while you do certain things.

Please answer each question by indicating how much you agree with the statement, or how much you think it is true of you. Please answer each item, without spending too much time on any one item. There are no right or wrong answers.

Please try to think about the most upsetting habits that you feel you have to do and can’t stop. For example, feeling that you have to wash your hands far too often, or repeating the same action over and over, or constantly checking that the doors and windows are shut properly.

15. How much do these habits get in the way of school or doing things with friends?(Required)

Part Two: In this section, each of the questions asks you about “thoughts”, ideas or pictures that keep coming into your mind even though you do not want them to do so. They may be unpleasant, silly, or embarrassing. For example, some young people have the repeated thought that germs or dirt are harming them or other people, or that something unpleasant may happen to them or someone special to them. These are thoughts that keep coming back, over and over again, even though you do not want them.

Please answer each question by choosing how much you agree with the statement, or how much you think it is true of you. Please answer each item, without spending too much time on any one item. There are no right or wrong answers.
