The effectiveness of local norms with two short forms of the MMPI was investigated in this study. Comparisons were made between high-point code-type concordance rates and the overall concordance rates generated by local norms and the original norms of Faschingbauer's Abbreviated MMPI (FAM) and the MMPI-168. The use of local norms did not produce significantly higher high-point code-type concordance rates than the use of original norms. The use of local norms was indicated when one is interested in overall profile concordance. However, this finding was not replicated in the cross-validation samples. No conclusion was reached regarding the superiority of one short form over the other in terms of high-point codetype concordance. In terms of overall concordance, the FAM was found to generate higher concordance rates than the MMPI-168 when original norms were used. Overall concordance rates were not significantly different between the two short forms when local norms were used. Design changes and possible explanations for the findings were discussed. The former included increasing the sample size of the cross-validation samples to reduce sampling error. The latter consisted of the lack of congruence between the factor structures of the FAM and MMPI-168 and that of the MMPI, possible similarities between the populations sampled and those upon which the FAM and MMPI-168 were standardized, and inadequate sample size.
