title: The test-retest reliability and stability of the WAIS-R in a sample of mentally retarded adults.
abstract: Fifty mentally retarded adults were administered the Wechsler Adult Intelligence Scale-Revised (WAIS-R) on two separate occasions, with the mean amount of time between testings being 2 years, 8 months. The data were examined in an effort to study the test-retest reliability and stability of the WAIS-R with the mentally retarded. Based on correlational, t-value and percentage of scale score change information, the authors concluded that the WAIS-R IQs appeared to possess good test-retest reliability and stability over an approximate 2.5 year period for the present sample of mentally retarded adults.
