An adaptation of the MMPI-2 Meyers Index for the MMPI-2-RF.

Using an overall sample of 278 individuals who had taken the Minnesota Multiphasic Personality Inventory-Second Edition (MMPI-2) and who had clear diagnostic information available in their medical records, the Meyers Index (MI) for the MMPI-2 (Meyers, Millis, & Volkert, 2002 ) was calculated for each individual, and a new version of the MI created for the MMPI-2 Restructured Form (MMPI-2-RF) was calculated. The MI is a method of combining multiple MMPI-2 validity scales into a single weighted index to assess exaggerated self-report on the MMPI-2. The new index is intended to provide the same type of global assessment of validity but for the MMPI-2-RF (MI-r).

Are Self-Ratings of Functional Difficulties Objective or Subjective?

In this study, we compared objective neuropsychological data using the Meyers Neuropsychological Battery (MNB; Meyers & Rohling, 2004 ) and self-report measures of emotional distress using the Symptom Checklist 90-Revised (SCL-90-R; Derogatis, 1994 ) with self-ratings of functional difficulties as measured by the Patient Competency Rating Scale (PCRS; Prigatano, 1986 ). The results showed a high correlation between the PCRS and scales on the SCL-90-R (r = .65), whereas correlation with the overall test battery mean of the MNB was quite small (r = .
