Personality style codetype concordance between the MCMI and MBHI.

Personality scale profiles of Millon's Clinical Multiaxial Inventory and Behavioral Health Inventory were analyzed for codetype concordance using a sample of psychiatric patients with medical symptoms (N = 91). Results indicated that at least half of the sample would be diagnosed with a personality disorder by each instrument. Approximately 95% of the sample produced at least one elevated scale. The tests were not significantly different with respect to their classification rates of pathology or number of scales elevated and demonstrated significant and positive correlations between complementary scales. Nonetheless, codetype correspondence was found to be 29.67% for single scales and 20.88% for two-point codetypes. Correlational data, factor analysis, and paired mean score comparisons were used to analyze these findings.
