Meet the Author: MMPI-A-RF co-author Robert Archer, Ph.D. shares details about his background in adolescent psychology and the development of this brand new test.
What are the three most important things that people should know about the MMPI-A-RF?
First, that the MMPI-A-RF is heavily informed by the MMPI-2-RF and represents an adaptation of this instrument for use with adolescents. However, the MMPI-A-RF also contains a number of validity and substantive scales that were uniquely designed to address issues related to adolescent development and psychopathology. Second, the MMPI-A-RF is an empirically supported test with extensive reliability and validity data. For example, the MMPI-A-RF Manual provides over 17,000 correlations between MMPI-A-RF scale scores and external criteria in a variety of adolescent samples. Finally, I think that test users will appreciate the 241-item length of the MMPI-A-RF, particularly because it may make adolescents more willing to complete a broad-band self-report personality assessment instrument. The 241 items are a subset of the 478-item MMPI-A booklet.
What was the primary goal in developing the MMPI-A-RF?
The central objective in the development of the MMPI-A-RF was to improve on the discriminant validity of the MMPI-A by reducing the ubiquitous and confounding influence of the demoralization factor commonly found in most personality inventories and the extensive item overlap across the MMPI-A scales. The MMPI-A-RF was created to reduce the redundancy found among MMPI-A scales by isolating the demoralization factor and reducing its influence on the “seed” or “core” components of the MMPI-A-RF scales. This process resulted in shorter scales (in contrast to their MMPI-A counterparts) with comparable convergent validity but improved discriminant validity.
