What psychological assessment tool measures personality traits?

The Minnesota Multiphasic Personality Inventory (MMPI) is a comprehensive psychological assessment tool specifically designed to measure various personality traits and psychopathology. It is widely used in clinical settings for psychological evaluation and diagnosis. The MMPI consists of a series of statements to which individuals respond in a true or false format, allowing for the assessment of a wide range of psychological conditions and personality styles.

Its structured format and empirical basis make it a robust tool for psychologists looking to gain insights into an individual's personality characteristics, emotional functioning, and possible psychological issues. The test is standardized and has normative data that provides a reference for interpreting the scores, which enhances its reliability and validity in assessing personality traits.

Other options may assess different aspects of psychology. For example, the Rorschach Test is a projective test that analyzes perceptions of ambiguous inkblots to uncover underlying thought processes and emotions, rather than directly measuring personality traits. The Wechsler Scale primarily assesses cognitive abilities and intelligence, while the California Psychological Inventory focuses on personality characteristics related to social interactions and personal adjustment but is not as widely recognized as the MMPI for in-depth personality assessment. Thus, the MMPI stands out as the most effective and scientifically validated tool for measuring personality traits in this context.
