The study utilized testing data from 440 psychiatric inpatients from a small Midwestern city. Testing was conducted utilizing the MMPI-2 and MCMI-III over the course of approximately 10 years. MMPI-2 data was converted to updated scales of the instrument, and specifically examined were the higher order scales of the MMPI-2 Restructured Format(RF). The Higher Order scales were correlated with Axis I scales of the MCMI-III. MCMI-III scales were placed in a three factor model representing Emotionality, Thought Disorder, and Behavioral/Acting out. These factors were correlated with RF scales. Factor analysis and canonical correlation describes the relationship between the two sets of scales and convergent validity of the RF HO scales is discussed. Overall, the HO scales show expected correlations with dimensions of the MCMI-III Axis I scales and the presence of the dimensions are also suggested by the factoring of the MCMI-III scales.
