MCMI-II ITEM WEIGHTS - THEIR LACK OF EFFECTIVENESS

Millon Clinical Multiaxial Inventory II (MCMI-II; Millon, 1987) result s from 134 patients were scored twice; with and without the item weigh ts. The results showed that the correlations between the weighted and unweighted versions of the same scales were extremely high, exceeding .90 in all cases. Furthermore, weighting did not significantly reduce the correlations among the scales, either within each of the four synd rome/pattern categories of the MCMI-II, or between categories. It is c oncluded that item weighting reduces the access of the MCM-II by clini cians, without increasing its psychometric properties.
