This brief report examines the relationship between the scale scores derived through weighted and unweighted item scoring on the Millon Clinical Multiaxial Inventory-II (MCMI-II). The inventories of 356 subjects across three samples were scored using weighted and unweighted algorithms. Correlations between the weighted and unweighted MCMI-II scales were found to approach unity. This casts doubt on whether the weighting system has substantial effect on the profiles that are generated or on reducing interscale correlations.
