Subtest specificities were determined for each of the 11 WAIS-R subtests for a sample of 200 psychiatric inpatients. The subtest's shared variance (defined as the multiple squared correlation between a subtest and all remaining subtests) was subtracted from reliable variance (defined as the subtest's reliability) to yield a measure of subtest specificity. The Information, Arithmetic, Vocabulary, f1p4rehension, Similarities, Picture Arrangement, and Digit Symbol subtests were judged to have adequate to ample specificity for ipsative interpretation. The Object Assembly, Digit Span, Picture Completion, and Block Design subtests were judged to have inadequate specificity for ipsative interpretation. Implications for the interpretation of WAIS-R results with psychiatric inpatients are discussed.
对200名精神病住院患者样本的韦氏成人智力量表修订版（WAIS-R）的11个分测验分别确定了分测验特异性。从可靠方差（定义为分测验的信度）中减去分测验的共同方差（定义为一个分测验与所有其余分测验之间的多重平方相关），以得出分测验特异性的度量。信息、算术、词汇、领悟、相似性、图片排列和数字符号分测验被判定具有足够到充分的特异性用于个体内解释。图形拼凑、数字广度、图片完成和积木图案分测验被判定具有不足的特异性用于个体内解释。讨论了对精神病住院患者WAIS-R结果解释的意义。
