What type of assessment is the MMPI primarily categorized as?

The Minnesota Multiphasic Personality Inventory (MMPI) is primarily categorized as a personality assessment tool. It was designed to evaluate various psychological conditions and personality traits by measuring a range of psychological constructs through a standardized questionnaire. This tool helps in understanding the individual’s personality structure, coping styles, and underlying psychological concerns.

The MMPI is particularly known for its comprehensive approach to identifying personality characteristics and potential psychopathologies, which makes it an essential tool in clinical psychology. It includes questions that assess various aspects of personality, which helps clinicians in developing a nuanced understanding of an individual's mental health and personality profile.

In contrast, while the MMPI can provide insight into emotional and mood-related aspects, it is not specifically a mood disorder assessment or a clinical diagnosis tool focused on particular disorders, which makes it distinct from the other options. The MMPI’s broader focus on personality rather than strictly on substance use further cements its categorization as a personality assessment.
