Correlations Between the MMPI and the Scale for the Assessment of Positive Symptoms and the Scale for the Assessment of Negative Symptoms in Schizophrenic Patients

Our study examined the relationship between the Minnesota Multiphasic Personality Inventory (MMPI) and the Scale tor the Assessment of Positive Symptoms (SAPS; Andreason, 1984) and the Scaie for the Assessment of Negative Symptoms (SANS. Andreason. 1983) in patients who me; the Diagnostic and Statistical Manual of Mental Disorders (3rd ed., rev.; American Psychiatric Association, 1987) diagnostic criteria for schizophrenia (n = 1.25). A significant correlation was found between the SAPS Delusions scale and Scaie 6 (Paranoia), the SAPS Positive Thought Disorder Scale and Scale F (Infrequency), and the SAPS Positive Thought Disorder and Scaie 9 (Hypomania). Additional analysis also shows, however, that severity of symptoms was the best predictor of MMPi scores. Consistent with previous studies, the MMPI appears useful for screening but not fot the detailed evaluation of symptomatology of schizophrenic patients. © 1994, Taylor & Francis Group, LLC.
