Test-retest reliability of the WAIS-R Satz-Mogel short form in a normal elderly sample.
Test-retest reliability of the WAIS-R Satz-Mogel short form was tested on a sample of 122 normal elderly volunteer subjects with mean age of 70.4. Subjects' performance was assessed over 3 annual probes. Reliability coefficients for sums of scaled scores on Verbal subscale and Full Scale ranged between 0.79 and 0.83. Corresponding coefficients for Performance subscale ranged between 0.70 and 0.72. The percentage of subjects who showed change between two probes of more than 1 SD was the highest for the Performance subscale. Implications for clinical use, particularly for the purpose of estimation of premorbid intellectual functioning are discussed.
