Convergent validity of the MMPI-A and MACI scales of depression.

The purpose of this study was to investigate the extent to which the depression scales of the Minnesota Multiphasic Personality Inventory-Adolescents (MMPI-A) and the Millon Adolescent Clinical Inventory (MACI) show convergence with a sample of 252 adolescents from an inpatient psychiatric facility. Both inventories were administered as part of the intake process. Pearson correlations were computed among the (a) MMPI-A Scale 2 (Depression), (b) MMPI-A Depression Content Scale, (c) MACI Doleful Personality Scale, and (d) MACI Depressive Affect Scale. There was no significant difference between the mean scores. Evidence of convergent validity between the two tests was moderate.
