Final answer:
The Minnesota Multiphasic Personality Inventory (MMPI) and the Rorschach Inkblot Test are among the instruments commonly used to screen for SUD, with MMPI being a self-report inventory and the Rorschach being a projective test.
Step-by-step explanation:
Among the instruments commonly used to screen for Substance Use Disorder (SUD), the Minnesota Multiphasic Personality Inventory (MMPI) is a self-report inventory that is widely used. It consists of a series of true/false questions which aid in providing a clinical profile for the individual. The MMPI is known for its reliability scales which test the instrument's consistency over time.
Another common method for personality assessment, particularly for revealing a person's unconscious desires, fears, and struggles, is the projective test. The Rorschach Inkblot Test is one example of a projective test that uses symmetrical inkblot cards to assess these unconscious aspects of an individual. It has been standardized and is effective in measuring facets of personality such as depression, psychosis, and anxiety. However, other instruments like the Beck Depression Inventory are also in use for more specific screening like depression, which can co-occur with SUD though they are not primarily used for SUD assessment.
