Which one of the following tests is considered an objective psychological test?

The Minnesota Multiphasic Personality Inventory (MMPI) is considered an objective psychological test because it utilizes standardized questions with specific scoring protocols, enabling quantifiable assessments of psychological functioning. Unlike projective tests such as the Rorschach and the Thematic Apperception Test, which rely on subjective interpretation of responses, the MMPI provides a structured format that leads to consistent and measurable outcomes.

The MMPI consists of true-false statements that the test-taker responds to, and the results are interpreted based on established norms and scales for various psychological conditions. This makes it a reliable tool for assessing personality traits and psychopathology, facilitating comparisons across different patient populations.

In contrast, projective tests like the Rorschach and the Thematic Apperception Test are less standardized. They require interpretation based on the individual's responses to ambiguous stimuli, which can be influenced by the clinician's subjective view. Similarly, while the Sentence Completion Test may yield insights into a person’s thoughts and feelings, it too invites a degree of subjective analysis rather than strictly objective measurement.

Thus, the MMPI stands out as an effective tool in psychological assessment due to its objective nature, reliability, and widespread acceptance in clinical practice.
