The MMPI–2 Restructured Clinical Scales: A Paradigmatic Shift in Scale Development

Tellegen et al. (2003) proposed fundamental changes in MMPI–2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) scale development by discarding empirical scale development in favor of construct validation via Jackson's (1970) sequential system of scale development. As a result of their efforts, a general distress factor (Demoralization) was identified and 8 Restructured Clinical (RC) Scales were developed. Using 7,330 clinical cases from Caldwell's (1997) data set, in this study, we sought to cross-validate the MMPI–2 RC Scales. Scale homogeneity was confirmed with high alpha coefficients and interitem correlations in the expected range. We also achieved a major objective of reducing interscale correlations. In replicating Tellegen et al.'s principal components analysis, we achieved a high concordance for 6 of the 8 RC Scales. We critically examine these results in light of Jackson's construct validation. We discuss the clinical usefulness of the MMPI–2 RC Scales within the context of current and future research.
