The Millon Adolescent Clinical Inventory-II (MACI-II®)

By Theodore Millon, PhD, DSc, Robert Tringone, PhD, Seth Grossman, PsyD, Carrie Millon, PhD

Ordering the MACI

The MACI-II is available through Pearson Clinical.

Unlike many other psychological tests which were developed for adults and adapted for adolescents, the Millon Adolescent Clinical Inventory-II was specifically created to address the unique concerns, pressures, and situations adolescents face. Anchored in Dr. Theodore Millon’s personality theory, this inventory helps assess personality patterns, self-reported concerns, and clinical symptoms in adolescents being evaluated or treated in a variety of mental health settings.

At 160 items, the MACI-II is much shorter than comparable instruments and is almost self-administering. The great majority of teens can complete the inventory in approximately 20 minutes, minimizing resistance among the population for which the test is intended. As with the MCMI-IV, this instrument has seen the development of a series of facet subscales (the MACI-II Grossman Facet Scales) to further refine the clinical domains that call for the clinician’s special attention.
