The interpretative validity of the FAM: long-term psychotherapists' ratings of psychiatric inpatients

Comparative validity of the MMPI and two short forms: psychiatric ratings

Minnesota Multiphasic Personality Inventory (MMPI) scales were used to predict psychiatric ratings in two male and two female groups of adult state psychiatric hospital inpatients. The resulting regression coefficients were cross-validated on the other same-sex group using MMPI, MMPI-168, and Faschingbauer Abbreviated MMPI (FAM) scales as predictors. The validity coefficients obtained in this manner were generally small and similar across MMPI forms. There was a trend for MMPI-based predictions to be superior to those of the short forms as the validity coefficients grew larger. This finding suggested caution in the use of the MMPI-168 and FAM as substitutes for the full MMPI. A suggestive for blending realism and rigor in future research is offered.

Comparative evaluation of two MMPI short forms with chemical abusing inpatients

Studied several novel analyses of the correspondence between two popular MMPI short forms and the full MMPI, including multivariate profile analyses and analyses of change scores. Pre- and posttreatment MMPIs were collected from 100 veterans in a treatment program for alcohol and drug problems. Scores for the Faschingbauer Abbreviated MMPI and the MMPI-168 were extracted from full MMPI protocols. Each short form was compared separately with the full form in several individual-case-oriented and group-data-oriented analyses. Significant differences between full and both short form profiles were found. It was concluded that neither short form is recommended for individual case descriptions, that significant problems arise in using these short forms for group descriptive or comparative research, and that these short forms show moderately acceptable correspondence with full MMPIs over time. It appears that short MMPIs continue to show serious deficits in reliability, i.e., in correspondence with full MMPIs, in spite of recent attempts to demonstrate validity somewhat independent of the full MMPI.

Correspondence between psychological reports based on the Mini-Mult and the MMPI

In order to assess the utility of the Mini-Mult with a university counseling center clientele, MMPI answer sheets of 10 students at the University of Miami Counseling Center were scored for both the MMPI and the Mini-Mult. Four judges completed psychological reports (Q-item questionnaires) based on the profiles. Correlations between judges' responses to MMPI and Mini-Mult profiles were calculated as an indication of the correspondence between the two tests. In addition, correlations between judges' responses to repeated presentations of MMPI profiles were calculated as an indication of the judges' reliability over time. The results do not support the use of the Mini-Mult with a university counseling center clientele.
