The MMPI-168 with inpatient drug abusers

A retrospective study was done on the MMPI responses of 120 inpatient drug abusers, comparing the standard MMPI with a short form composed of the first 168 items. Scores "predicted" by the short form were highly correlated with actual scores, and the predicted and actual profile configurations were very similar. Regression equations derived from the data were comparable to those presented by other authors using different diagnostic groups; this suggests a rather stable relationship between the MMPI--168 and the standard MMPI. The use of the short form for drug-abuse patients is encouraged.
