Previous studies have replicated the four-factor structure of the WISC-III in children with traumatic brain injury (TBI) and demonstrated the sensitivity of WISC-III indexes to severity of injury. This archival study examined the growth curve characteristics of the indexes following traumatic brain injury. The primary hypothesis was that there is systematic variability in the components (e.g., slope) of the curves. Subjects included 40 children with documented loss of consciousness, age at injury 9.3 years (SD = 2.6), 68% severe TBI, evaluated with a full WISC-III a minimum of three times post-injury. Growth curve analyses with hierarchical linear modeling, conducted with factor scores recalculated as non-age-standardized z scores, indicated that although the intercept was reliable and could be predicted by injury characteristics, there was little systematic variation in index growth rates. Findings suggest that WISC-III indexes are of limited utility as repeated measures of recovery following TBI.
以往的研究已在创伤性脑损伤（TBI）儿童中复制了韦氏儿童智力量表第三版（WISC - III）的四因素结构，并证明了WISC - III各指标对损伤严重程度的敏感性。这项档案研究考察了创伤性脑损伤后各指标的生长曲线特征。主要假设是曲线的组成部分（如斜率）存在系统变异性。研究对象包括40名有记录显示曾失去意识的儿童，受伤时年龄为9.3岁（标准差 = 2.6），68%为重度TBI，在受伤后至少接受三次完整的WISC - III评估。使用分层线性模型进行生长曲线分析，将因素得分重新计算为非年龄标准化的z分数，结果表明，虽然截距可靠且可通过损伤特征进行预测，但指标增长率几乎没有系统变化。研究结果表明，作为TBI后恢复情况的重复测量指标，WISC - III各指标的效用有限。
