Therefore, a K correction is not applied on the RC Scales. 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 (in non-clinical settings). It will include scales that assess constructs associated with Clinical Scales 5 and 0. A shorter, restructured version of the MMPI-2, anchored by the RC Scales, is in development. Scale 5 does not assess a currently recognized clinical disorder, and Scale 0 measures a normal–range personality trait. The RC Scales were designed to measure clinical phenomena. Why don't scales 5 and 0 have corresponding RC Scales? Will they have RC Scales? These data are 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.” What are the internal consistencies of the RC Scales? These data are 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.”
What are the test-retest reliabilities of the RC Scales? 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. He then identified the major dimensions of eight of the ten scales, excepting Scales 5 and 0, and constructed scales measuring those dimensions. 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.” The author of the scales, Auke Tellegen, first developed a demoralization scale, extracting the general complaint or malaise factor from the existing Clinical 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.” Extensive additional research on the RC Scales has been published in journal articles, book chapters, and books. What is the research base for the RC Scales? A shorter, restructured version of the MMPI-2 in which the RC Scales serve as the core scales, is in development. They include items that appear after item 370 in the MMPI-2 booklet. The RC Scales are not a shortened version of the MMPI-2 test. Subsequent research provides further data to guide and support RC Scale interpretation.Ĭan I administer just the items that comprise the RC Scales as a "short" MMPI-2 administration, similarly to administering the first 370 items and printing the Basic Service Report (includes 10 Clinical Scales and 3 Validity Scales-L, F, K)? The Test Monograph by Tellegen, Ben-Porath, McNulty, Arbisi, Graham, and Kaemmer (2003) provided initial empirical data to guide RC Scale interpretation. They are part of the standard test materials. They are not considered “experimental” because sufficient data exist to support their recommended use in practical applications of the MMPI-2 test.
