Conversion equations for two modified MMPI short forms.
Extracted the MMPI-168 and Faschingbauer Abbreviated MMPI (FAM), along with the K scale items normally excluded from those MMPI short forms, from the full MMPIs of about 535 psychiatric inpatients. Those scales augmented by K items were used to estimate full MMPI scores via regression and substitution equations. The equations were cross-validated on samples of about 545 from the same population. Shrinkage was minimal and cross-validation estimates compared favorably with derivation estimates from other short-form studies.
