Which of the following is an example of a widely used objective personality test?

The Minnesota Multiphasic Personality Inventory (MMPI) is a widely used objective personality test primarily because it employs standardized questionnaires with fixed response options, allowing for clear scoring and interpretation. This test is designed to assess various dimensions of personality and psychopathology, making it a valuable tool in clinical settings for diagnosing mental health conditions.

The MMPI features statements that respondents answer with "True" or "False," which helps in collecting quantitative data to evaluate a person's mental and emotional well-being. Its extensive empirical research and comprehensive validation have contributed to its reputation as a reliable instrument in psychological assessment, distinguishing it from projective tests such as the Rorschach Inkblot Test, the California Psychological Inventory, and the Thematic Apperception Test, which are more subjective and interpretive in nature.
