Note on the reliability of three MMPI short forms.

The Mini-Mult, FAM, and MMPI-168 were evaluated for correspondence with the full form MMPIs of 252 adult psychiatric inpatients. Although the correlations of each short form's estimated full-scale score with the corresponding actual full-form scale were high, only the FAM was able to reasonably predict the full-form single high-point code. The range of difference scores between short forms and the corresponding full-form scales was very wide and there was a low agreement rate with the full-form. These results contradict those of Newmark, Ziff, Finch, and Kendall (1978) and raise doubts about the utility of these three short forms.
