Murray. Along with the Minnesota Multiphasic Personality Inventory (MMPI) and the Rorschach inkblot test, the TAT is one of the most widely used psychological tests.
The MMPI is used to screen for personality and psychosocial disorders in adults (i.e., over age 18) and adolescents age 14 to 18.
The original MMPI was developed at the University of Minnesota and introduced in 1942.
The MMPI should be administered, scored, and interpreted by a qualified clinical professional trained in its use, preferably a psychologist or psychiatrist.
The MMPI is only one element of psychological assessment, and should never be used as the sole basis for a diagnosis.
