The purpose of screening is early diagnosis and treatment. Screening tests are usually administered to people without current symptoms, but who may be at high risk for certain diseases or conditions.

Aside from a yearly doctors visit there are no screening tests or screening guidelines for obsessive-compulsive disorder. There are some research tools, though, that doctors use when studying obsessive-compulsive disorder (OCD) symptoms. The Yale-Brown Obsessive Compulsive Scale, for people aged 14 and older, is commonly used. There is also a version of this scale to be used with children.
