The utility of the MAPI in the assessment of depression

The relationships between the Millon Adolescent Personality Inventory (MAPI; Millon, Green, & Meagher, 1982) and depression, as assessed by the Multiscore Depression Inventory (MDI; Berndt, 1968) were examined. Elevations on the MDI subscales were positively related to elevations on MAPI personality style Scale 2 (Inhibited) and Scale 8 (Sensitive) and on six of the eight MAPI expressed concerns scales. MAPI personality style Scale 4 (Sociable) and Scale 5 (Confident) were negatively correlated with the MDI. MAPI code types containing either Scale 2 or 8 were associated with a high MDI full-scale score. The subjects who received a MAPI computer-generated diagnosis of borderline personality disorder also had elevated MDI full-scale scores. The findings of this study appear consistent with the existing body of MAPI research, and the data suggest that the MAPI personality style scales may have both state and trait qualities.
