title: Family-size and birth-order in obsessional neurosis.
abstract: Family size and birth-order of 156 British-born patients diagnosed as having obsessive-compulsive neurosis were determined from case-notes; these were compared with matched controls. Separate consideration was given to male and female patients. Mean family size of obsessionals was found to be smaller than that of controls. An excess of first-born was found among male obsessional patients.
