The Lynfield Obsessional/Compulsive Questionnaires

The need for adequate methods of measuring symptoms in obsessional disorders is stressed, particularly since, owing to the comparative rarity of the condition, a multicentre approach will be necessary if controlled studies are envisaged. A new method of measurement, the Lynfield Obsessional/Compulsive Questionnaire, is described. The questionnaire is derived from the Leyton Obsessional Inventory and may be of value in showing response to treatment.
