The staffs at three extended care facilities identified a group of 10 hypochondriacal patients. The research team asked these 10 patients and 59 controls, 27 questions relating to health attitudes and behaviors. Six items were found to be fairly useful in distinguishing hypochondriacal from non-hypochondriacal subjects. These six items were taken as the Hypochondriasis Scale for Institutional Geriatric Patients (HSIG), and each patient scored on the basis of his responses to these six items. This test proved to be one way of distinguishing between hypochondriacal and non-hypochondriacal groups (P less than .005). However, because of the possibility of false positive results, the scale should be used only to confirm staff suspicions of hyponchondriasis and should not be used as part of the clinical intake procedure.
