Abstract
In this comment, I address a number of the points raised in the reviews of the MMPI–2 RestructuredClinical (RC; Tellegen et al., 2003) Scales by Nichols (2006/this issue) and Rogers, Sewell, Harrison, and Jordan (2006/this issue), and I advocate for changes in assessment validation research. There is little evidence that the "syndromal complexity" Nichols ascribes to the original MMPI–2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) Clinical Scales is worth preserving. Although their construction does not constitute the paradigm shift claimed by Rogers et al., the RC Scales are promising, psychometrically defensible measures of core features of the original MMPI–2 Clinical Scales. However, validation of inferences from multiscale inventories such as the MMPI–2 is limited at present by a disconnection between the integrative manner in which MMPI–2 profiles are interpreted and the scale-by-scale nature of most MMPI–2 validation studies. Q-sort procedures show promise for operationalizing integrated MMPI–2 interpretations, with both research and teaching applications.
