WAIS-RC简式用于精神病人的效度分析

Validity of the WAIS-RC Short Forms with Psychiatric inpatients

目的：对ＷＡＩＳ－ＲＣ简式进行效度检验，以探讨其在精神病人中的应用价值。方法：被试全部为住院精神病人，其中精神分裂症和躁郁症患者各５０例，均符合ＣＣＭＤ－２－Ｒ诊断标准。每个被试完成ＷＡＩＳ－ＲＣ全式测验，全式智商由所有言语及操作分测验计算，简式智商采用回归法换算。结果：二合一与全式智商的相关为０．７３～０．９４，四合一为０．８３～０．９７，六合一均在０．９５以上。精神分裂症患者简式与全式智商均值的差异非常显著，而躁郁症患者除ＰＩＱ外也有显著性差异。结论：同国外多数研究结果不一致，不支持ＷＡＩＳ－ＲＣ简式用于精神病人。

Objective:To examine the validity of the WAIS-RC short forms in psychiatric inpatients so as to investigate their applied value. Methods: Subjects were 100 psychiatric inpatients diagnosed according to the CCMD-2-R criteria. Among the 100 subjects, one half had schizophrenias and the rest were manic-depressives. Each subject was administered a complete WAIS-RC. The full scale IQ was calculated using all verbal and performance subtests. All short form IQ estimates were calculated and converted to IQ scores by using regression formulas. Results:The correlations between full scale IQ and short form IQ estimates were 0.73～0.94 for the two-subtest, 0.83～0.97 for the four-subtest, and above 0.95 for the six-subtest. However, differences between the means of the short form IQs and the full scale IQ were significant except the PIQ of manic depressive patients. Conclusion: Overall results are not consistent with many overseas studies and do not support the use of these short forms with psychiatric inpatients.
