The Lynfield Obsessional-Compulsive questionnaires measure symptoms in obsessional disorders. They are derived from the Leyton Obsessional Inventory, which had the disadvantage of taking a relatively long time to administer. The questionnaires can be used to monitor response to treatments.
There are 2 questionnaires which use the same questions, but differ in the responses. These are designed to measure either the resistance of the patient to the symptoms, or the interference with other activities that the symptoms cause.
