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 among the original scales, were found in the outpatient sample. The former provided evidence of convergence between the two sets of scales, whereas the latter increases the potential for discriminant validity in the restructured scale profiles. Mean T-scores of the restructured scales were significantly lower than their original scale counterparts for every clinical scale except Scale 1 (hypochondriasis). Individual profiles exhibited fewer scale elevations using the restructured clinical scales (M = 2.15, Mdn = 2.0) than the original clinical scales (M = 3.29, Mdn = 3.0). The majority of client profiles (56%) had fewer scale elevations when plotted using the restructured scales versus the original clinical scales.
