The MMPI in the differential diagnosis of organicity vs. schizophrenia: empirical findings and a somewhat different perspective.

Watson's MMPI Scale for differentiating organicity from schizophrenia was found to correlate significantly with the MMPI Schizophrenia Scale and was found not to differentiate significantly better than the Schizophrenia Scale for the two patient groups under consideration. Watson's general approach of using personality measures for such differential diagnosis was lauded, although doubt that his scale is superior to other methods of diagnosing schizophrenia was expressed.
