[Intelligence testing in early old age. The correlation between the multiple-choice vocabulary test (MCVT-B) and the progressive matrices test (PMT) in a patient cohort in early old age].

Taking a random sample of 147 patients a substantial correlation of 0.54 between the "Mehrfachwahl-Wortschatz-Test (MWT-B)" by Lehrl and the "Progressiver Matrizen-Test" by Raven could be found. The MWT-B did not show significant differences between the age groups of 34-44 years, 45-54 years and 55-64 years. In the PMT differences between the age groups only showed up when the raw-scores were converted to IQ-scores (reffering to the corresponding age groups). Using the raw-scores no significant differences could be determined. Investigating an average IQ of 109 in the PMT, we found an average IQ of 97 in the MWT-B for the same patients. A main reason for the superelevated IQ-scores in PMT seems to be the reference to different age groups. A new standardization of the test should be undertaken.
