我们检查了 51 名临床转介的不同年龄的 8 至 16 岁儿童（M 年龄 = 11.24 岁，SD = 2.36）中韦克斯勒儿童智力量表第四版 (WISC-IV) 分数的稳定性。儿童被转介到城市大学培训诊所接受检查； 70%的符合条件的儿童在12个月至40个月后完成了随访测试（M=22.05，SD=5.94）。指数得分的稳定性范围为 0.58（处理速度）到 0.81（语言理解），全量程 IQ 的稳定性为 0.86。子测试分数稳定性范围为 0.35（字母数字排序）到 0.81（词汇）。人们认为更容易受到注意力集中影响的指标（处理速度和工作记忆）稳定性较低。我们还研究了注意力问题作为 WISC-IV 指数和分项测试分数稳定性的潜在调节因素。与没有注意力问题的儿童相比，有注意力问题的儿童在数字广度和矩阵推理子测试中的稳定性显着较低。这些结果为 WISC-IV 的时间稳定性提供了支持，并且还为以下观点提供了一些支持：注意力问题导致儿童在完成 WISC-IV 时产生不太稳定的 IQ 估计。我们希望我们的报告能够鼓励进一步检验这一假设及其含义。
We examined the stability of Wechsler Intelligence Scale for Children-Fourth Edition (WISC-IV) scores among 51 diverse, clinically referred 8- to 16-year-olds (M-age=11.24 years, SD=2.36). Children were referred to and tested at an urban, university-based training clinic; 70% of eligible children completed follow-up testing 12 months to 40 months later (M=22.05, SD=5.94). Stability for index scores ranged from .58 (Processing Speed) to .81 (Verbal Comprehension), with a stability of .86 for Full-Scale IQ. Subtest score stability ranged from .35 (Letter-Number Sequencing) to .81 (Vocabulary). Indexes believed to be more susceptible to concentration (Processing Speed and Working Memory) had lower stability. We also examined attention problems as a potential moderating factor of WISC-IV index and subtest score stability. Children with attention problems had significantly lower stability for Digit Span and Matrix Reasoning subtests compared with children without attention problems. These results provide support for the temporal stability of the WISC-IV and also provide some support for the idea that attention problems contribute to children producing less stable IQ estimates when completing the WISC-IV. We hope our report encourages further examination of this hypothesis and its implications.
