There are no screening tests or screening guidelines for obsessive-compulsive disorder. There are some research tools, though, that doctors use when studying 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.
