THE DIAGNOSIS AND ASSESSMENT OF DEPRESSION, MANIA, AND PSYCHOSIS BY SELF-REPORT

We examined the usefulness of the Minnesota Multiphasic Personality Inventory (MMPI), the original and revised versions of the Millon Clinical Multiaxial Inventory (MCMI and MCMI-II), and the Symptom Checklist-90-R (SCL-90-R) for the diagnosis and assessment of depression, mania, and psychosis in a heterogeneous group of 272 psychiatric inpatients. We examined the following: diagnostic efficiency of single scales at-specified cutoff scores for these conditions, multidimensional test profiles, MMPI high-point codes, and associated MCMI and MCMI-II personality disorders. The reported findings are discussed in terms of how these tests may and may not be used to answer particular assessment questions and what the self-report vantage contributes to the entire clinical assessment process.
