The Differential Personality Inventory was administered to 25 North American Indians hospitalized for the treatment of alcoholism. Indians scored significantly higher than a comparison group of 75 non-Indian alcoholics on 7 of 27 clinical scales, reflecting Cynicism, Disorganization of Thinking, Hypochondriasis, Ideas of Persecution, Repression, Self-depreciation, and Somatic Complaints. There were no significant differences on scales reflecting character disorder. It was recommended that separate norms be developed on standardized measures of psychopathology for specific ethnic groups.
