Psychological Tests
Overview
Personality assessment is often considered more of an art than a science. Despite efforts to standardize and objectify the process, generations of clinicians have developed psychological tests and structured interviews designed to elicit information from respondents in a consistent manner. This methodology allows any differences in responses to be attributed to the distinct personalities of individuals.
Objective Testing
Many tests limit the range of possible responses. For example, the Minnesota Multiphasic Personality Inventory II (MMPI-II) requires "true" or "false" answers. The results are then scored automatically, with "true" responses awarding points on various scales, while "false" responses do not. This automation minimizes the diagnostician's role to interpreting results, which can still introduce some bias. However, the standardized structure of these tests helps to curb such biases.
Comprehensive Testing
Practitioners often use a battery of tests and structured interviews to obtain a complete understanding of a subject’s personality. These tests differ in their response formats, stimuli, administration procedures, and scoring methods. Reliability is established when a test yields consistent results over repeated administrations with the same client.
Validity and Consistency
The results of different tests should align to form a coherent picture of the subject's personality. Inconsistent results across tests may indicate a lack of validity. For instance, a test measuring grandiosity should correlate with tests assessing reluctance to admit flaws or the tendency to present a socially desirable image. Unrelated correlations, such as with intelligence or depression, would question the test's validity.
Types of Tests: Objective vs. Projective
Psychological tests are generally classified as objective or projective. In objective tests, scoring is often computerized and requires minimal human input. These include instruments like the MMPI-II, the California Psychological Inventory (CPI), and the Millon Clinical Multiaxial Inventory II. Interpretation of these results depends on the therapist's expertise and insight.
Projective tests are less structured and more ambiguous. According to L.K. Frank, patient responses in these tests reveal their worldview, meanings, and feelings. The Rorschach inkblots are a well-known example. In projective testing, responses are more subjective and open to interpretation, which can introduce bias. Different clinicians may yield varying interpretations due to differing scoring methods and personal influence.
Conclusion
Psychological testing is a complex blend of structured methodologies and human interpretation. While standardized tests strive to minimize bias, the art of interpreting results remains crucial. The effectiveness of these tests depends largely on the diagnostician's skill in synthesizing data into a comprehensive understanding of an individual's personality.
