Abstract
This study compares two pathological personality disorder scales and two severe clinical syndrome scales from the Millon Clinical Multiaxial Inventory in relation to clinical change from admission to discharge on the major dimensions of the Brief Psychiatric Rating Scale. For a sample of 52 inpatients, 17 with schizophrenia, 27 with major depression, and 8 with bipolar (manic) disorder, we investigated the prognostic utility of these Millon scales for identifying clinical improvement. Findings indicated that, while the Millon scales identified admission levels of psychopathology on three Brief Psychiatric Rating Scales, the Millon inventory predicted clinical improvement on only the brief rating of Thinking Disturbance. These findings are considered in light of prognosis as a clinical research question that is distinct from diagnostic discrimination and case identification.
