Comment on Merydith and Phelps (2009): “Convergent Validity of the MMPI–A and MACI Scales of Depression”

Abstract

In 2009, Merydith and Phelps reported convergent validity of scales in the Minnesota Multiphasic Personality Inventory–Adolescent (MMPI–A) and the Millon Adolescent Clinical Inventory (MACI) that assess depression with a sample of adolescent psychiatric inpatients. This comment addresses analysis of these data, cites selected research on sex and the two inventories, and restates the recommendation that researchers routinely examine such data separately by sex before proceeding with combined-sex analyses.
