This in turn would result in expected intercorrelations between scales, and would produce scales that, while intercorrelated, would still have subtle and clinically different meanings (Broughton, 1984).
Thus, the multidimensionality of the scales combined with their item overlap would be not so much a weaknesses of the MMPIIMMPI-2/MMPI-A, but would be expected, given the nature of the constructs.
Accurate interpretation, however, would need to include an awareness of the subtle differences and similarities between scales.
