Compared an estimated Psycholinguistic Quotient, based on Cronkhite and Penner's (1975) revised scoring procedure for the ITPA Psycholinguistic Age, to the WISC-R Verbal, Performance, and Full Scale IQs of developmentally disabled children. The Quotient entered into strong relationships with the WISC-R Verbal and Full Scale IQs. The diagnostic significance of these correlations was discussed. The data indicated that the estimated Psycholinguistic Quotient was a valid measure for screening intellectual status in this population.
将基于克朗凯特和彭纳（1975年）对伊利诺伊心理语言能力测验（ITPA）心理语言年龄的修订评分程序所估算的心理语言商数，与发育障碍儿童的韦氏儿童智力量表修订版（WISC-R）言语智商、操作智商和全量表智商进行比较。该商数与WISC-R言语智商和全量表智商呈现出强相关性。讨论了这些相关性的诊断意义。数据表明，估算的心理语言商数是筛查该人群智力状况的有效指标。
