New version > Millon Adolescent Clinical Inventory-II (MACI-II)


Unlike many other instruments developed for adults and adapted for adolescents, the MACI assessment was specifically created to address the unique concerns, pressures and situations facing teens.

This dedicated tool, enhanced by the addition of Grossman Facet Scales, helps assess personality patterns as well as self-reported concerns and clinical symptoms.

Brief and easy to administer, the MACI test can assist practitioners in constructing treatment plans customised to individual needs—and help them guide troubled youth towards healthier, more authentic lives.

This versatile instrument is essential in helping to:

  • Conduct detailed evaluations to confirm diagnostic hypotheses

  • Create individualised treatment planning

  • Measure progress before, during and after treatment

Key Features

To help you formulate more precise treatment plans, the Grossman Facet Scales identify personality processes (e.g., self-image, mood temperament) that underlie overall scale elevations on the Personality Pattern scales. Each personality scale now has three facet scales, for which results are presented in the automated reports.

Using an age-appropriate format, the MACI test helps measure a number of factors closely associated with adolescents, including Sexual Discomfort, Substance Abuse Proneness, Suicidal Tendency and Eating Dysfunctions.

Taking 30 minutes or less to complete, the MACI test is designed to obtain the maximum amount of information with a minimal amount of the test-taker’s effort — a feature that mental health professionals have found especially helpful in working with adolescents.


The normative population of the MACI test consists exclusively of clinical adolescent patients, offering relevant comparisons. The sample includes 1,017 adolescents from outpatient, inpatient and residential treatment programs in 28 states and Canada. The delineation of four distinct norm groups further enhances the test’s usefulness:

  • Males 13–15 years old

  • Females 13–15 years old

  • Males 16–19 years old

  • Females 16–19 years old
