Invalid Reports and Demographic Defaults

What are the required demographic values and scorability rules for an MMPI-2-RF administration?

Test Date, Birth Date, ID, and Gender must be filled in. The software will not print any report without this information. Age is calculated from the Test Date and Birth Date. If the client is younger than 18, no report will be printed. Years of Education, Marital Status, and Ethnic Origin are not required but can be entered.

My MMPI-2-RF Score Report is invalid, but it doesn't say that on the report. Why not?

The Score Report provides profiles and scores for the MMPI-2-RF scales and item-level data, but does not provide an interpretation, including an assessment of whether the protocol is valid. It is left to the user to address scale invalidity in his or her interpretation. Recommended cutoffs for identifying invalid protocols are provided in the MMPI-2-RF Manual for Administration, Scoring, and Interpretation.

How does the MMPI-2-RF Interpretive Report deal with invalid protocols?

For protocols that are invalid because of elevated VRIN-r or TRIN-r scores (T ≥ 80 on either scale), unscorable responses are listed, but critical responses are not. Scores on the inconsistency scales are interpreted.

For protocols that are invalid and uninterpretable because of elevated F-r (T=120) or Fp-r (T ≥ 100) scores, or % scorable < 70 on any of the validity scales, unscorable responses and critical responses are listed along with an interpretation of any scores on the Validity Scales that remain interpretable.

Critical responses are listed so that the interpreter can see the kind of statements the test taker was endorsing in generating an over-reporting protocol. Invalid reports are clearly marked with an invalidity message on each profile.

My MMPI-2 report was scorable and valid, but my MMPI-2-RF report was not scorable and valid. Which test and report should I rely upon?

The MMPI-2-RF Validity Scales are similar but not identical to the MMPI-2 Validity Scales. The former are less redundant (e.g., there is no item overlap on the VRIN-r and TRIN-r scales) and more up-to-date (e.g., unlike F, F-r includes only items rarely endorsed by the MMPI-2 normative sample). Because all of the MMPI-2-RF items are embedded in the MMPI-2, if the MMPI-2-RF report indicates that the protocol is invalid, then the MMPI-2 results are likely invalid as well and should not be interpreted. In an opposite case, if an MMPI-2 protocol is invalid and the MMPI-2-RF report indicates that the protocol is valid, the MMPI-2-RF results can be interpreted with caution.

Norms and Scales

Do the MMPI-2-RF norms differ from the MMPI®-2 norms?

The MMPI-2-RF normative sample is drawn from the MMPI-2 normative sample and consists of 1,138 men and 1,138 women between the ages of 18 and 80 from several regions and diverse communities in the U.S. The MMPI-2-RF T scores are non-gendered and non-K-corrected. No new norms were collected for the MMPI-2-RF.

Are there norms for different cultures for the MMPI-2-RF test?

American minorities are included in the normative sample. There are no separate cultural norms.

What is the FBS-r (Symptom Validity) Scale?

The FBS-r (Symptom Validity) Scale provides information regarding non-credible symptom reporting and has been found particularly useful in neuropsychological assessments. For more information about the FBS-r, visit: http://psychcorp.pearsonassessments.com/NR/rdonlyres/A25DB8F8-435F-4066-801B-B641978A97DA/0/MMPI2FBS.pdf  

Are the Restructured Clinical (RC) Scales in the MMPI-2-RF the same as the RC Scales in the MMPI-2?

Yes. For more information about the RC Scales, visit: http://psychcorp.pearsonassessments.com/haiweb/cultures/en-us/productdetail.htm?pid=PAg523

Are the MMPI-2-RF T scores K corrected?

No. Research indicates that the K correction does not enhance validity and that in some cases validity of the original MMPI and MMPI-2 Clinical Scales is actually attenuated by the K correction. Consequently, no K correction is applied to any MMPI-2-RF scales. The K-r scale is only used as a measure of under-reporting.

 


 

Administration, Scoring, and Interpretation Help and other Information

What is the RBS Scale?

The Response Bias Scale (RBS) is an over-reporting indicator associated with exaggerated or non-credible memory complaints. References to RBS studies can be found here.

Can I create my own comparison group?

Yes. Users can create user-customized comparison groups based on data within their Q Local database. See chapter 5 of the MMPI-2-RF User's Guide for Reports (2011) for detailed instructions.

Why didn't I receive all of the references in the End Notes section of my MMPI-2-RF Interpretive Report: Clinical Settings?

References are printed only for studies relied upon in generating correlate-based interpretive statements in a specific report. This enhancement was introduced in version 2.3 of Q Local software. An up-to-date list of all MMPI-2-RF references can be found at: here.

Can the MMPI-2-RF Interpretive Report serve as a complete and independent psychological report on a client?

No. As noted on each report, the statements contained in the narrative represent a professional-to-professional consultation and do not serve as an independent or "stand-alone" report. The following notice appears in the MMPI-2-RF reports: “The interpretive report is intended for use by a professional qualified to interpret the MMPI-2-RF. The information it contains should be considered in the context of the test-taker’s background, the circumstances of the assessment, and other available information.”

Can I exchange unused MMPI-2 report usages for MMPI-2-RF usages?

Please call us at 1-800-627-7271 to discuss the exchange of MMPI-2 report usages for MMPI-2-RF usages

Can I print an MMPI-2 report and an MMPI-2-RF report for the same test-taker?

Yes, the Score and Print Report menu for an MMPI-2 administration includes an option to generate an MMPI-2-RF report (available with Q Local software versions 2.7 and higher). An MMPI-2-RF usage will be required to generate the MMPI-2-RF report for the test-taker's administration. See chapter 5 of the MMPI-2-RF User's Guide for Reports (2011) for detailed instructions.

Can I administer an “abbreviated” MMPI-2 test (first 370 items only) and get an MMPI-2-RF report?

No. The MMPI-2-RF is composed of items throughout the entire MMPI-2 test booklet.

Where can I find further information about the MMPI-2-RF Interpretive Report?

The MMPI-2-RF User's Guide for Reports is available from NCS Pearson, Inc.

Ben-Porath, Y. S., & Tellegen, A. (2008). MMPI-2-RF User's Guide for Reports. Minneapolis, MN: University of Minnesota Press.

Are there tables in the MMPI-2-RF manuals converting MMPI-2 item ordering to MMPI-2-RF item ordering and vice versa?

Yes, in Appendix E of the MMPI-2-RF Manual for Administration, Scoring, and Interpretation (2008).

Are all MMPI-2-RF scales copyrighted?

Yes.

Should I use the MMPI-2-RF instrument in light of the recent ADA (Americans with Disabilities Act) and the Civil Rights Act?

Pearson cannot offer legal advice; we recommend that you seek the opinion of competent employment counsel to ensure that you obtain the most appropriate advice for your individual circumstances. The apparent impact of the ADA on the use of the MMPI-2-RF instrument relates to the timing of the administration. Because the MMPI-2-RF instrument appears to be classified as a medical examination under the ADA, it must be administered subsequent to a conditional offer of employment being tendered by an employer. Under the Civil Rights Act of 1991 ("CRA") it is inappropriate to use tests with either race or sex norms in the employment domain. The MMPI-2-RF norms are not based on race or sex.

RC Scales 

What kind of documentation is available for the RC Scales?

A test monograph by Tellegen, Ben-Porath, McNulty, Arbisi, Graham, & Kaemmer (2003), titled The MMPI-2 Restructured Clinical (RC) Scales: Development, Validation, and Interpretation, includes: an introduction providing the rationale for creating the RC Scales, information about how the scales were developed, detailed psychometric information on the reliability and validity of the RC Scales, recommendations for interpreting the RC Scales, case examples illustrating RC Scale interpretation, and a discussion of future directions in RC Scale research and application. This document also includes detailed appendixes specifying the item composition of the scales and raw-to-uniform T-score conversion tables. (Available from Pearson, Product # 29433.) See also the MMPI-2-RF Manual for Administration, Scoring, and Interpretation for an extensive discussion of the scales. Numerous publications on the RC Scales have appeared in the journal and book literature, including the text by Yossef S. Ben-Porath, Interpreting the MMPI-2-RF (2012), available from the University of Minnesota Press.

What is the research base for the RC Scales?

The development and validation of the scales is documented in the first chapter of a test monograph by Tellegen, Ben-Porath, McNulty, Arbisi, Graham, & Kaemmer (2003), titled The MMPI-2 Restructured Clinical (RC) Scales: Development, Validation, and Interpretation, available from Pearson (Product # 29433).  Numerous publications on the RC Scales have appeared in the journal and book literature, including the text by Yossef S. Ben-Porath, Interpreting the MMPI-2-RF (2012), available from the University of Minnesota Press.

How were the RC Scales developed?

The development of the scales is documented in the first chapter of a test monograph by Tellegen, Ben-Porath, McNulty, Arbisi, Graham, & Kaemmer (2003), titled The MMPI-2 Restructured Clinical (RC) Scales: Development, Validation, and Interpretation, available from Pearson (Product # 29433), and in the text by Yossef S. Ben-Porath, Interpreting the MMPI-2-RF (2012), available from the University of Minnesota Press.

The author of the scales, Auke Tellegen, first isolated the general distress or  “demoralization” component of the existing Clinical Scales. He then identified major distinctive and maximally demoralization-free components of the ten scales and constructed a set of new scales measuring these components for eight of the scales (not for Scales 5 and 0).  

Do the RC Scales overlap?

No, they do not. It was the intent of the scales’ developer, Auke Tellegen, to construct scales that would each measure a major distinctive dimension currently embedded in the Clinical scales.

Why don't scales 5 and 0 have corresponding RC Scales?

The RC Scales were designed to assess psychopathology. Scale 5 does not assess a currently recognized clinical disorder, and Scale 0 measures a normal–range personality trait. The MMPI-2-RF, anchored by the RC Scales, includes scales that assess constructs associated with Clinical Scales 5 and 0.

What are the intercorrelations of the RC Scales, and, in comparison, of the Clinical Scales?

Intercorrelations of both sets of scales on several samples are reported in Tables 4-6 through 4-12 of a test monograph by Tellegen, Ben-Porath, McNulty, Arbisi, Graham, & Kaemmer (2003), titled The MMPI-2 Restructured Clinical (RC) Scales: Development, Validation, and Interpretatinn, available from Pearson (Product # 29433). As expected, the RC Scales are considerably less strongly intercorrelated (considerably more distinctive) than are the Clinical Scales.

What are the test-retest reliabilities of the RC Scales?

This information is provided in Tables 4-4 and 4-5 of a test monograph by Tellegen, Ben-Porath, McNulty, Arbisi, Graham, & Kaemmer (2003), titled The MMPI-2 Restructured Clinical (RC) Scales: Development, Validation, and Interpretation, available from Pearson (Product # 29433).  See also the MMPI-2-RF Technical Manual.

What are the internal consistencies of the RC Scales?

This information is provided in Tables 4-4 and 4-5 of a Test Monograph by Tellegen, Ben-Porath, McNulty, Arbisi, Graham. & Kaemmer (2003), titled The MMPI-2 Restructured Clinical (RC) Scales: Development, Validation, and Interpretation, available from Pearson (Product # 29433).  See also the MMPI-2-RF Technical Manual.

Do I use the traditional cut-offs to evaluate elevations on the RC Scales?

Yes, with the same precautions one should observe for employing any recommended cut-offs, namely that they be considered guidelines identifying points at which the interpretive focus should shift, rather than as fixed points demarcating qualitative change.

Are the RC Scales K-corrected? Why not?

The RC Scales are not K-corrected. Research indicates that the K correction either does not affect the validity of the Clinical Scales (in clinical settings) or significantly attenuates the validity of the scales. A K correction is therefore not applied to the RC Scales.

Are the Clinical Scales less valid than the RC Scales?

Research has established that in comparison with the Clinical Scales, the RC Scales have comparable to improved convergent validity and substantially improved discriminant validity.

What is the Demoralization Scale?

The Demoralization Scale provides an appraisal of the test-taker’s current overall sense of well-being. As such, it can serve as the starting point for the RC Scale interpretation process. It was constructed by extracting to the extent possible from the Clinical Scales the general distress component present in all the Clinical Scales as well as in most other MMPI-2 scales.

Are the RC Scales useful with non-clinical populations that typically produce within-normal-limits profiles, like personnel/employee testing and child custody evaluations?

The RC Scales can also be effective with non-clinical populations.  Corey and Ben-Porath (CITE PCIR UG) review studies that support and guide use of the RC Scales in pre-employment assessments of police officer candidates. This body of research indicates a need to use lower (than the traditional T score 65) cut-offs in assessments of risk for negative outcomes in police candidates. Table 4-6 includes recommended cut-offs for the RC Scales.

A recurring question about the relationship of the MMPI-2-RF to the MMPI-2:

How do the Clinical Scales and the RC Scales differ in how they assess psychopathology?

Multiple elevations on the Clinical Scales may reflect comorbidity and/or demoralization, making it difficult to accurately determine the presence of actually comorbid and complex syndromes. The relatively low demoralization saturation of the RC Scales and their improved discriminant properties enable users to more accurately identify the necessary elements of a syndrome and the occurrence of comorbidity.
