The factor analytic studies that have been done with the Millon Clinical Multiaxial Inventory (MCMI), a 175-item paper-and-pencil test designed to evaluate symptomology in psychiatric patients, have been problematic in that the test's high inter-scale correlation could lead to an artificially robust factor structure. The present investigation…

The diagnostic accuracy of nonadjusted and bootstrapped diagnosis was compared using a sample of 1,455 psychiatric patients who completed the Millon Clinical Multiaxial Inventory. The usefulness of bootstrapping depended on the criteria for accuracy. Conditions under which bootstrapping might increase diagnostic accuracy are detailed. (SLD)

Scale-level factor analyses are reported for 2 self-report measures of psychopathology, the Symptom Checklist-90-R (SCL-90) and the Millon Clinical Multiaxial Inventory (MCMI), using 130 psychiatric inpatients and outpatients. Used separately, the measures offer limited interpretability of scale profiles. Their combined use permits differentiation…
