The MCMI-II as a treatment outcome measure for psychiatric inpatients.

Recently, the MCMI-II (Millon, 1987) has been introduced as a successor to the MCMI-I (Millon, 1983). This study evaluated the MCMI-II as a treatment outcome measure for psychiatric inpatients. Ninety-eight patients were tested at admission and discharge with the MCMI-II. Changes in mean MCMI-II scores on the basic and pathological personality scales, as well as the moderate and severe symptom scales, were generally congruent with findings from a previous outcome study with the MCMI-I (Piersma, 1986a). However, several differences between the MCMI-II and MCMI-I were noted, which suggests that the MCMI-II will need to be cross-validated as an instrument distinct from the MCMI-I.
