WAIS-RC简式测验校正后常模在智力残疾鉴定中的应用

目的探讨韦氏成人智力量表(WAIS-RC)简式测验校正后常模在智力残疾鉴定中的应用效度。方法随机取128例作智力残疾鉴定的精神发育迟滞(MR)患者，测得其标准全式总智商(FIQ)，再根据原标准化常模以及校正后的新常模，分别以Tellegen法计算其四合一简式FIQ，并进行比较分析。结果原常模和新常模简式FIQ与全式之间均呈显著正相关(P＜0.01)；均值比较原常模简式FIQ高于全式(P＜0.01)，新常模简式FIQ与全式之间差异无统计学意义(P＞0.05)；按全式智商重度缺损组其新常模简式的等级划分符合率与原常模一样均为0.00%；中度和轻度缺损组比原常模要高(P＜0.01)。结论校正后的WAIS-RC简式测验效度优于原常模简式，但对重度缺损者不适用。

Adjusted Norm of WAIS-RC Short Forms in Identification of Intellectual Disability

ObjectiveTo investigate the application validity of the adjusted norm of WAIS-RC in the identification of intellectual disability.Methods128 patients with mental retardation (MR) were chosen for identification of the intellectual disability, measured their full scale IQs (FIQ) according to the original norm, calculated their four-subtest short forms FIQ respectively by Tellegen way according to the original standard norm and the new adjusted norm, then compared and analyzed the outcomes.ResultsThe short forms FIQ according to the original and the new norm had high correlation to full forms FIQ (P<0.01). The average of the short forms FIQ was higher than full forms FIQ according to the original norm (P<0.01), showing no significant difference according to the new norm(P＞0.05). In severe intelligence defected group according to full forms IQ, the grade classification corresponding rate of short forms FIQ according to the new norm was 0.00%, as well as the original norm. That in medium and mild intelligence defected groups was higher than that of original norm(P＜0.01).ConclusionThe test validity of adjusted norm short forms of WAIS-RC is superior to the original norm, but not suitable for severe intelligence defected.
