The aim of the investigation was to compare rating scales for syndromes as given by a psychological test, the Minnesota Multiphasic Personality Inventory (MMPI), with those derived from a standardized psychiatric history (CAPRICE System). The first is dependent on information supplied directly by the patient, who answers a check-list; the second is based on a psychiatric interview and the completing of a codified case-history. The computerized form of the MMPI was employed (Fowler and Miller, 1969), and the scales selected were those corresponding with manifest anxiety (At scale); depression (D scale); phobias, obsessions and compulsions (Pt scale); and schizophrenia (Sc scale). The nearly corresponding scales derived from the CAPRICE System (Valentine, 1973) are the scales for Anxiety, Depression, Obsessional-Compulsive Disorder, and Psychosis.
