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.
五十名成年智障者分两次接受了韦氏成人智力量表修订版（WAIS-R）测试，两次测试之间的平均时间间隔为2年8个月。对这些数据进行了分析，旨在研究WAIS-R在智障者中的重测信度和稳定性。基于相关性、t值以及量表分数变化信息的百分比，作者得出结论，对于当前这批成年智障者样本而言，WAIS-R智商分数在大约2.5年的时间里似乎具有良好的重测信度和稳定性。
