Thirty-six mentally retarded adolescents were administered the Wechsler Intelligence Scale for Children (WISC), the Peabody Picture Vocabulary Test (PPVT), and the Slosson Intelligence Test (SIT) to determine reliability and comparable performance among the three intelligence tests. Correlations as a function of IQ and MA, by sex, were computed among the three tests. All were significant (p less than .01), but the WISC and SIT had consistently higher relationships than any other comparisons on both IQ and MA. Analyses also indicated that the PPVT produced higher IQ scores than the WISC or SIT and that MA in the PPVT was influenced by the previous administration of the SIT. It was concluded that, as a screening device, the SIT is more reliable and approximates WISC scores more consistently than the PPVT.
对36名智力发育迟缓的青少年进行了韦氏儿童智力量表（WISC）、皮博迪图片词汇测验（PPVT）和斯洛森智力测验（SIT），以确定这三种智力测验之间的信度和可比表现。计算了三种测验之间按性别、智商和心理年龄的相关性。所有相关性均显著（p小于0.01），但在智商和心理年龄方面，WISC和SIT之间的关系始终比其他任何比较都更高。分析还表明，PPVT产生的智商分数高于WISC或SIT，且PPVT中的心理年龄受之前进行的SIT的影响。得出的结论是，作为一种筛查工具，SIT比PPVT更可靠，且与WISC分数的一致性更高。
