The trials of separating bath water from baby: a review and critique of the MMPI-2 Restructured Clinical Scales.

چکیده

I review the development of the new set of MMPI-2 scales, the Restructured Clinical (RC) Scales (Tellegen et al., 2003). I identify several conceptual and methodological flaws in the construction of these scales, and I discuss the influence of a central shortcoming, the use of an atypical and depressively biased marker for unwanted ("first-factor") variance and its consequences for the RC Scales. I criticize the monograph introducing and describing the development of these scales for multiple important omissions. I provide examples of RC Scales in which relevant variances were overextracted or underextracted in the process of their construction. I introduce and apply the concept of "construct drift" to the RC Scales corresponding to the MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) Clinical Scales, Psychasthenia and Hypomania. I conclude that the RC Scales are highly redundant with and function as routinely scored Content scales and that their designation as Clinical Scales is at best tenuous. I present two more appropriate, unbiased markers for the first factor along with the description of several nonintrusive strategies for increasing the independence of the Clinical Scales without compromising their syndromal fidelity.

Further evidence on the validity of the MMPI-2 Restructured Clinical (RC) Scales: addressing questions raised by Rogers, Sewell, Harrison, and Jordan and Nichols.

The reviews by Rogers, Sewell, Harrison, and Jordan (2006/this issue), and by Nichols (2006/this issue) offer markedly contrasting appraisals of the MMPI-2 Restructured Clinical (RC) Scales introduced by Tellegen et al. (2003). The one common feature is that both reviews draw on the same atypical MMPI-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) data set for their empirical analyse...

Let's not get hysterical: comparing the MMPI-2 validity, clinical, and RC scales in TBI litigants tested for effort.

The MMPI-2 restructured clinical (RC) scales replace the traditional clinical scales in the MMPI-2 restructured form (MMPI-2-RF). Few studies to date have examined the MMPI-2 RC scales in traumatic brain injury (TBI) litigants. We compared MMPI-2 validity, clinical, and RC scales profiles of 83 mild, complicated mild, and moderate/severe TBI litigants who were tested for effort. Past research s...

Examination of the MMPI-2 restructured form (MMPI-2-RF) validity scales in civil forensic settings: findings from simulation and known group samples.

The current study examined the effectiveness of the MMPI-2 Restructured Form (MMPI-2-RF; Ben-Porath and Tellegen, 2008) over-reporting indicators in civil forensic settings. The MMPI-2-RF includes three revised MMPI-2 over-reporting validity scales and a new scale to detect over-reported somatic complaints. Participants dissimulated medical and neuropsychological complaints in two simulation sa...

Independent validation of the MMPI-2-RF Somatic/Cognitive and Validity scales in TBI Litigants tested for effort.

The MMPI-2 Restructured Form (MMPI-2-RF; Ben-Porath & Tellegen, 2008) is replacing the MMPI-2 as the most widely used personality test in neuropsychological assessment, but additional validation studies are needed. Our study examines MMPI-2-RF Validity scales and the newly created Somatic/Cognitive scales in a recently reported sample of 82 traumatic brain injury (TBI) litigants who either pass...

A comparison of the correlational structures and elevation patterns of the MMPI-2 restructured clinical (RC) and clinical scales.

The relationship between the MMPI-2 restructured clinical scales and the original clinical scales was evaluated using an outpatient clinical sample (N = 150). Similar patterns of correlations to those reported by Tellegen et al. in 2003, such as high correlations between the restructured scales and their original scale counterparts and lower intercorrelations among the restructured scales than ...
