What Is The Millon Adolescent Clinical Inventory?

According, the following can be mentioned about the Millon Adolescent Clinical Inventory:

At 160 items, the MACI inventory is much shorter than comparable instruments. The MACI test is almost self-administering. Terminology is geared to an sixth-grade reading level. The great majority of youngsters can complete the inventory in approximately 20 minutes, minimizing resistance among the population for which the test is intended. The MACI test is linked directly to a coherent theory of personality and psychopathology, significantly increasing the inventory’s interpretive value. Personality scales reflect adolescent variants of the adult personality disorders, refined through Millon’s Evolutionary model. No other diagnostic instrument currently available is as consonant with the official nosology as the MACI test. Moreover, the MACI inventory’s scales are grouped to reflect the DSM distinction between Axis II and Axis I. Thus, separate scales distinguish the more enduring personality characteristics of patients (Axis II) from the more acute clinical disorders they display (Axis I). Profiles based on all scales may be interpreted to illuminate the interplay between long-standing characterological patterns and the distinctive clinical symptoms currently manifest. As noted, the addition of what are termed the Grossman Facet Scales assist the clinician in further refining the utility of the MACI by identifying the youngster’s most salient domains that are problematic, thereby providing an optimal guide for therapy and counseling.

What Scales Are Used On The Millon Adolescent Clinical Inventory?

According to, the following scales are represented on this inventory:

The MACI test consists of a total of 31 scales: Twelve Personality Patterns scales (Axis II), eight Expressed Concerns Scales, seven Clinical Syndrome Scales, three Modifying Indices (which assess particular response styles), and a Validity scale. The table below lists the inventory’s scales. The twelve personality patterns parallel those of the DSM-III, III-R, and IV. The Expressed Concerns scales focus on feelings and attitudes about issues that tend to concern most troubled adolescents. The Clinical Syndromes scales assess disorders frequently seen in adolescent populations. As noted, in 2006, a series of Facet Subscales oriented to the personologic/clinical domains have been added to the basic personality scales.
