Test for OCD

Director of the Anxiety Disorders Treatment Center and is an international expert in the treatment of anxiety disorders, with books translated into nine languages.

The following questionnaire will help you identify the types of problems that most trouble you.

Read through the statements listed and note the ones that are true for you. If you note two or more items in any group, this is an indication that you should specifically address those concerns in your self-help program. Don't be surprised if you check more than one item in several groups. Many people have more than one type of OCD symptoms.
