BORDERLINE AND SCHIZOPHRENIC-PATIENTS - A COMPARISON USING THE MCMI-II

In the present study we examined the Millon Clinical Multiaxial Invent ory-II scores of psychiatric patients with a diagnosis of either borde rline personality disorder (BPD; n = 13) or schizophrenia (n = 13). Th e analyses revealed that the BPD patients were significantly elevated on a number of scales in addition to the Borderline scale. The second goal of this study was to assess the discriminative validity of the Bo rderline and Thought Disorder Scales with both base rate (BR) cutoffs and the number of endorsed prototypic items, The Borderline scale demo nstrated the most diagnostic power when using BR cutoffs, whereas the Thought Disorder scale performed poorly, no better than chance levels, with all cutoffs.
