ABSTRACT
The Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) is a 478-item objective personality assessment instrument designed for use with adolescents. It provides an array of validity and clinical scales, and interpretation is facilitated by a substantial research literature. The MMPI-A is an adaptation of the Minnesota Multiphasic Personality Inventory (MMPI), and therefore an understanding of its development, psychometric characteristics, and research base necessarily begins with a history and description of the MMPI.
