Comparability of Scores on the MMPI–2–RF Scales Generated With the MMPI–2 and MMPI–2–RF Booklets

In most validity studies on the recently released 338-item MMPI–2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) Restructured Form (MMPI–2–RF; Ben-Porath & Tellegen, 2008; Tellegen & Ben-Porath, 2008), scale scores were derived from the 567-item MMPI–2 booklet. In this study, we evaluated the comparability of the MMPI–2–RF scale scores derived from the original 567-item MMPI–2 booklet with MMPI–2–RF scale scores derived from the 338-item MMPI–2–RF booklet in a Dutch student sample (N = 107). We used a counterbalanced (ABBA) design. We compared results with those previously reported by Tellegen and Ben-Porath (2008). Our findings support the comparability of the scores of the 338-item version and the 567-item version of the 50 MMPI–2–RF scales. We discuss clinical implications and directions for further research.
