This study investigated the utility of the Hobby WISC-R Split-half Short Form in a sample of children and adolescents with severe head injury. Subjects included 30 patients with severe closed-head injuries who were referred for neuropsychological testing as part of their hospitalization in a pediatric rehabilitation center. Subjects ranged in age from 7.5 to 16.2 years and were of the low to middle socioeconomic range. Analyses yielded significant correlations between scores on the standard WISC-R and the Split-half Short Form. Except for the WISC-R Split-half Short Form slightly overestimating scores on Object Assembly, no other score differences were obtained between the two forms. Patterns of strengths and weaknesses were variable for the two forms, with over-all agreements ranging from 46% on the Performance subtests to 53.7% on the Verbal subtests. The rate of classification agreement between the standard and short-form formats in assigning a child to one of five traditional IQ categories was 76.7%, with nearly all scores on the short form falling within one standard error of measurement of the standard WISC-R scores. There was a tendency for younger children to show more stability in their classification categories across the two WISC-R forms than older children. Issues related to the use of the WISC-R Split-half Short Form for a severely head-injured pediatric population are discussed.
本研究调查了霍比韦氏儿童智力量表修订版（WISC-R）分半简式在重度颅脑损伤儿童及青少年样本中的效用。研究对象包括30名重度闭合性颅脑损伤患者，他们在一家儿科康复中心住院期间被转介进行神经心理学测试。研究对象年龄在7.5岁至16.2岁之间，社会经济地位处于低到中等水平。分析结果显示，标准WISC-R得分与分半简式得分之间存在显著相关性。除了WISC-R分半简式对积木图案分测验得分略有高估外，两种形式之间未发现其他得分差异。两种形式的优势和劣势模式各不相同，在操作分测验上总体一致性为46%，在言语分测验上为53.7%。在将儿童归入五个传统智商类别之一时，标准形式和简式形式之间的分类一致性率为76.7%，简式的几乎所有得分都落在标准WISC-R得分的一个测量标准误差范围内。与年龄较大的儿童相比，年龄较小的儿童在两种WISC-R形式中的分类类别表现出更大的稳定性。本文讨论了在重度颅脑损伤儿科人群中使用WISC-R分半简式的相关问题。
