The scales on the MMPI-II have particularly low intercorrelations amongst themselves, thus showing evidence of scale purity and discriminant validity.

MMPI-II

The Minnesota Multiphasic Personality Inventory-2, a comprehensive psychological questionnaire designed to assess a variety of psychological conditions and personality attributes.

Scale Purity

Scale purity is a concept in psychometrics referring to the degree to which items on a test measure a single, coherent construct or dimension, contributing to the test's validity.

Discriminant Validity

The degree to which a measure is not correlated with other variables from which it is theoretically supposed to differ.

  • Assess the validity and reliability as fundamental psychometric properties of multiple personality assessment instruments.
