Description: To examine the reliability and validity of the FAM and MMPI-168 with 50 nursing home residents, FAM and MMPI-168 items were extracted from the MMPI. T-tests revealed significant mean differences between the MMPI-168 and MMPI on scale 1, and on scale 8 for the FAM. To examine reliability, correlations between each MMPI scale and corresponding short form scales were calculated. A mean correlation of.78 for the MMPI-168 and.85 for the FAM was found. Since correlations were high but short form scales underestimated corresponding MMPI scales, the FAM and MMPI-168 may not be accurate substitutes for the MMPI with nursing home residents. Z score transformations were used to determine significance between correlations obtained in this study and corresponding correlations found in previous research which examined short form use with elderly VA patients. Several correlations between the short forms and the MMPI obtained in this study were significantly different from corresponding correlations found in previous research. Validity was examined by computing the percentage of agreement of code type matches between the MMPI and FAM, and between the MMPI and MMPI-168. The FAM and MMPI-168 permitted prediction of the highest scale in 53% and 46%, respectively, of the cases. Since high-point scores are usually the basis for diagnosis, the obtained low high-point correspondence suggests that using short forms as substitutes for the MMPI in diagnosis with nursing home residents is questionable. Chi-square analysis of ratings of judges was used to examine degree of correspondence between two-point code descriptions based on the MMPI-168 and on the MMPI. Since 56% of the two-point descriptions based on the MMPI and MMPI-168 were judged as not similar, interpretations based on MMPI-168 two-point code descriptions should not be considered equivalent to interpretations based on the full MMPI. A discussion of results and suggestions for future research are offered.
