Mapping the MMPI-2 Restructured Clinical scales onto normal personality traits: evidence of construct validity

The MMPI-2 Restructured Clinical (RC; Tellegen et al., 2003) scales were developed to remove common factor variance that saturates the clinical scales and create a more distinct set of measures, yielding a new set of scales with improved convergent and discriminant validity. In this study, we examined the relation between RC scale scores and scores on the Multidimensional Personality Questionnaire (MPQ; Tellegen, in press), a measure of normal personality, using a sample of 811 college students. The results indicate strong convergence between the RC scales and expected MPQ higher order factors and primary scales. The RC scales also demonstrated expected improved convergent and discriminant validity over the clinical scales.
