The Experimental Minnesota Multiphasic Personality Inventory (EMMPI) consists of 566 nonpathological personality items, where each item is paired with a corresponding item in the Minnesota Multiphasic Personality Inventory (MMPI) such that both items have approximately the same social desirability scale values and the proportion of True responses. The results of the secondary analysis applied separately to the 21 MMPI trait scales and to the corresponding 21 EMMPI scales indicated that their first factor loadings were congruent and both correlated highly with the proportion of items in the scales keyed for socially desirable responses. It is proposed that both the EMMPI and the MMPI first factors be named the positive self description (PSD) factor.
