Final answer:
The psychologist is likely using repeated assessments to establish a baseline for future assessments, monitor symptom changes over time, and individualize therapy. Tests such as the MMPI are used for this purpose, and projective tests can assess unconscious processes through individualized responses. Surveys are another method for collecting data efficiently.
Step-by-step explanation:
When a psychologist uses the same test more than once during the course of therapy, they are most likely trying to gauge the course of symptoms over time or establish a baseline for future assessments. Repeated testing allows the clinician to monitor changes and tailor the therapeutic approach to the patient's evolving needs. The consistency of such tests, such as the Minnesota Multiphasic Personality Inventory (MMPI), is crucial.
For instance, repeated MMPI testing helped identify an increased vulnerability to alcoholism, anxiety, and somatic symptoms in police officers over time. This longitudinal approach can help illustrate how personalities or symptom severity change in response to therapy or as a result of ongoing stressors
Projective tests, another assessment tool, evaluate unconscious processes through ambiguous stimuli. These tests, like the Rorschach Inkblot Test, require individuals to project their feelings onto the test material, making it difficult to deliberately present oneself in a certain light. The validity of these tests varies, with some being considered more reliable than others.
In addition to these personality assessments, surveys are also used by psychologists to quickly and efficiently collect data from a large number of participants. The administration of these tools, the interpretation of results, and the longitudinal design of the studies provide a comprehensive view of how patients change and recover over time.
