PREDICTION OF STANDARD MMPI SCALE SCORES FROM 71 ITEMS - MINI-MULT

SELECTED 71 ITEMS AS REPRESENTATIVE OF THE CONTENT CLUSTERS TAPPED BY THE 11 STANDARD VALIDITY AND CLINICAL MMPI SCALES. THE ABILITY OF THIS ITEM POOL TO PREDICT THE STANDARD SCALE SCORES WAS CONTRASTED WITH THE ABILITY OF A RETEST TO DO THE SAME. THE ABBREVIATED FORM (THE MINI-MULT) WAS ESTIMATED TO HAVE SUFFERED ONLY A 9% LOSS IN RELIABILITY AND A 14% LOSS IN CORRESPONDENCE IN COMPARISON WITH THE READMINISTRATION OF THE STANDARD FORM. CORRELATIONAL, CODE-TYPE, AND GLOBAL RATING DATA WERE USED IN ASSESSING THE DEGREE OF CORRESPONDENCE. THE LOSS IN RELIABILITY AND CORRESPONDENCE WAS NOT SUFFICIENT TO MITIGATE AGAINST THE USE OF THE MINI-MULT WHEN A STANDARD TEST COULD NOT BE OBTAINED. METHODOLOGICAL QUESTIONS RELEVANT TO THE USE OF THE SPEARMAN-BROWN FORMULA AND FACTOR ANALYSIS ARE DISCUSSED.
