When was mmpi developed

Butcher, W. Grant Dahlstrom, John R. Graham, and Auke Tellegen constituted the committee responsible for the standardization, with Beverly Kaemmer serving as coordinator for the University of Minnesota Press. The committee agreed to pursue two goals: improve the test while maintaining as much continuity as possible with the original MMPI.

Improvement took the form of the collection of new normative data, revision of outdated and offensive item content, addition of new item content, and development of new scales intended to augment the basic MMPI Validity and Clinical Scales; continuity was accomplished by minimizing changes to the Clinical Scales, thus making it possible for test users to rely on the decades of accumulated research and clinical experience with the MMPI. Several adolescent normative data sets were developed; the most frequently used norms were introduced by Marks and Briggs in Using the MMPI with adolescents presented a number of challenges: multiple normative data sets; item content inappropriate or irrelevant for this younger population; the absence of scales designed specifically to assess adolescent development and psychopathology.

Butcher, John R. Graham, Robert P. Adolescent normative data were collected, items relevant to this population were written, and adolescent-specific scales were constructed. By contrast, a major aim of the restructuring process was to revise those scales by dealing with scale heterogeneity and excessively high scale intercorrelations, long identified in the research literature as problematic psychometrically.

Ben-Porath Tellegen et al. The Bibliographic Database Since the s the MMPI instruments have provided valuable assessment tools for professionals in mental health, forensic, public safety, and medical settings. It is our hope that this database will prove useful to practitioners and researchers as the Test Division of the University of Minnesota Press continues to fulfill its commitment to ongoing MMPI instrument research and development.

Note: The Press is grateful to Dr. This has two advantages. Second, the MMPI-2 is based on empirical research and not on a clinician's assumptions about what answers indicate particular personality traits.

The data from MMPI-2 assessments are particularly useful in occupational health settings in complex presentations where doubt as to what is really wrong with the patient exists. For example, the MMPI-2 should normally be able to detect unconsciously somatizing or consciously malingering in patients [ 1 ].

One of the disadvantages of the MMPI-2 for the occupational health physician is that the MMPI-2 is a strictly licensed test and can only be purchased, administered and interpreted by a suitably experienced clinical psychologist or psychiatrist. As such, it should be regarded as a complex diagnostic investigation for relatively infrequent use.

These scales make it very difficult to fake the MMPI-2 results. The measure has many clinical scales assessing mental health problems i. The MMPI-2 was validated using a normative sample of adults.

A symptom validity scale FBS has been added to the inventory in recent years to help exclude symptom exaggeration and has been reported as having very low false-positive rates. Nordin et al. They found a strong relationship between reported pain disorder and conversion disorder experiencing psychological and emotional problems as physical pain. This is an extremely useful finding for occupational health physicians because it shows the utility of the MMPI-2 for determining whether a patient complaining of chronic pain would best benefit from medical treatment or psychological therapy.

The MMPI-2 can be obtained from www. Google Scholar. Google Preview. Oxford University Press is a department of the University of Oxford. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide.

Validity Scales were retained revised , two new Validity Scales have been added Fs in and RBS in , and there are new scales that capture somatic complaints. Additionally, the MMPIRF computer scoring offers an option for the administrator to select a specific reference group with which to contrast and compare an individual's obtained scores; comparison groups include clinical, non-clinical, medical, forensic, and pre-employment settings, to name a few. Use of the MMPI is tightly controlled.

Any clinician using the MMPI is required to meet specific test publisher requirements in terms of training and experience, must pay for all administration materials including the annual computer scoring license and is charged for each report generated by computer.

The original MMPI was developed on a scale-by-scale basis in the late s and early s. Theory in some ways affected the development process, if only because the candidate test items and patient groups on which scales were developed were affected by prevailing personality and psychopathological theories of the time.

However, the MMPI had flaws of validity that were soon apparent and could not be overlooked indefinitely. The control group for its original testing consisted of a very small number of individuals, mostly young, white, and married people from rural Midwestern geographic areas. The MMPI also faced problems with its terminology not being relevant to the population it was supposed to measure, and it became necessary for the MMPI to measure a more diverse number of potential mental health problems, such as "suicidal tendencies, drug abuse, and treatment-related behaviors.

Subsequent revisions of certain test elements have been published, and a wide variety of sub scales were introduced over many years to help clinicians interpret the results of the original 10 clinical scales. The current MMPI-2 has items, and usually takes between one and two hours to complete depending on reading level.

It is designed to require a sixth-grade reading level. The original form of the MMPI-2 is the third most frequently utilized test in the field of psychology, behind the most used IQ and achievement tests. The youth version was developed to improve measurement of personality, behavior difficulties, and psychopathology among adolescents.

It addressed limitations of using the original MMPI among adolescent populations. Children who are 18 and no longer in high school may appropriately be tested with the MMPI Some concerns related to use of the MMPI with youth included inadequate item content, lack of appropriate norms, and problems with extreme reporting.

For example, many items were written from an adult perspective, and did not cover content critical to adolescents e. Likewise, adolescent norms were not published until the s, and there was not consensus on whether adult or adolescent norms should be used when the instrument was administered to youth.

Finally, the use of adult norms tended to overpathologize adolescents, who demonstrated elevations on most original MMPI scales e. There is also a short form of items, which covers the basic scales validity and clinical scales.

The validity, clinical, content, and supplementary scales of the MMPI-A have demonstrated adequate to strong test-retest reliability, internal consistency, and validity. General Maladjustment, 2. Over-control repression L, K, Ma , 3. Si Social Introversion , 4. The MMPI-A normative and clinical samples included males and females, ages 14 to 18, recruited from eight schools across the United States and males and females ages 14 to 18 recruited from treatment facilities in Minneapolis, Minnesota, respectively.

Norms were prepared by standardizing raw scores using a uniform t-score transformation, which was developed by Auke Tellegen and adopted for the MMPI This technique preserves the positive skew of scores but also allows percentile comparison. Strengths of the MMPI-A include the use of adolescent norms, appropriate and relevant item content, inclusion of a shortened version, a clear and comprehensive manual,[24] and strong evidence of validity.

Critiques of the MMPI-A include a non-representative clinical norms sample, overlap in what the clinical scales measure, irrelevance of the mf scale,[24] as well as long length and high reading level of the instrument. From a theoretical perspective, the MMPIRF scales rest on an assumption that psychopathology is a homogeneous condition that is additive.
