Relationship between MCMI-II scales and normal personality traits

Area of Science:

• Psychological assessment
• Clinical psychology
• Personality research

Background:

• The Millon Clinical Multiaxial Inventory-II (MCMI-II) is a widely used tool for assessing personality disorders.
• Concurrent validity of psychological assessments is crucial for establishing their reliability and utility.
• Understanding personality constructs in couples therapy can inform treatment approaches.

Purpose of the Study:

• To evaluate the concurrent validity of the Millon Clinical Multiaxial Inventory-II (MCMI-II) scales.
• To examine the relationship between MCMI-II and 16PF Questionnaire profiles in a clinical population.
• To provide empirical support for the use of MCMI-II in assessing personality styles.

Main Methods:

• Correlational analysis of MCMI-II and 16PF Questionnaire data.
• Inclusion of 145 couples undergoing outpatient marital therapy.
• Statistical examination of associations between personality and clinical scales.

Main Results:

• Significant associations were found between MCMI-II and 16PF Questionnaire profiles.
• These associations were logically consistent with the underlying constructs of the MCMI-II scales.
• Concurrent validity was established for both Personality and Clinical Scales of the MCMI-II.

Conclusions:

• The findings support the concurrent validity of the MCMI-II.
• Results lend credence to research investigating Millon's basic personality styles in diverse populations.
• The study reinforces the utility of the MCMI-II in clinical and research settings.
