The validity scales are used to determine whether the test results are actually valid (i.e., if the test was truthful, answered cooperatively and not randomly) and to assess the test taker's response style (i.e., cooperative, defensive).Įach clinical scale uses a set or subset of MMPI-A questions to evaluate a specific personality trait. There are eight validity scales and ten basic clinical or personality scales scored in the MMPI-A, and a number of scales and subscales that may be used with the test. The results of the test reflect an adolescent's personality strengths and weaknesses, and may identify certain disturbances of personality (psychopathologies) or mental deficits caused by problems.
The ques tio ns ask ed on the MMP I-A are design ed to eval uat e the tho ught s, emotions, attitudes, and behavioral traits that comprise personality. There is also a short form of the test that is comprised of the firs t 350 items from the long-form MMPI-A. The MMPI-A has 478 true/false items, or questions, (compared to 567 items on the MMPI-2) and takes 45 minutes to an hour to complete (compared to 60 to 90 minutes for the MMPI-2). The adolescent inventory is shorter than the standard adult version, was developed at a sixth-grade reading level, and is geared towards issues and personality 'norms.'
The MMPI-A, a version of the inventory developed specifically for adolescents age 14 to 18, was published in 1992. The current standardized version for adults 18 and over, the MMPI-2, was released in 1989, with a subsequent revision of certain test elements in early 2001. Description The original was developed at the University of Minnesota and introduced in 1942. It is also frequently administered as part of a battery to evaluate cognitive functioning. Purpose The MMPI is used to screen for personality and in adults (i.e., over age 18) and adolescents age 14 to 18. Definition The Min nes ota Mul tip hasi c Per son ali ty Inv ent ory (MM PI -2 MMP I-A ) is a written psychological, or test, used to diagnose mental disorders.
