Which of the following is true about the MMPI-2?

The MMPI-2, or Minnesota Multiphasic Personality Inventory-2, is primarily designed to assess a person's personality traits and psychopathology. It is one of the most widely used psychological assessments in various settings, including clinical, forensic, and research contexts.

This test comprises numerous true or false statements that cover a wide array of psychological issues and personality characteristics. By analyzing the patterns of responses, practitioners can gain valuable insights into an individual's mental health and personality structure. It specifically helps in identifying psychological conditions, informing treatment plans, and improving understanding of an individual's behavior.

In contrast, other options do not accurately define the nature of the MMPI-2. For instance, it is not a performance-based test, which typically assesses abilities through tasks or challenges. Additionally, while it may assist in clinical diagnosis, it is not solely used for that purpose; its utility spans beyond just clinical settings to include research and various assessments within the mental health field. Furthermore, although the MMPI-2 can provide some qualitative insights based on responses, its main strength lies in the quantitative data it generates through standardized scales and profiles rather than subjective qualitative feedback. Thus, option B accurately captures the MMPI-2's primary function and relevance in psychological evaluation.
