Determination of neuropsychological impairment involves contrasting obtained performances with a comparison standard, which is often an estimate of premorbid IQ. M. R. Schoenberg, R. T. Lange, T. A. Brickell, and D. H. Saklofske (2007) proposed the Child Premorbid Intelligence Estimate (CPIE) to predict premorbid Full Scale IQ (FSIQ) using the Wechsler Intelligence Scale for Children-4th Edition (WISC-IV; Wechsler, 2003). The CPIE includes 12 algorithms to predict FSIQ, 1 using demographic variables and 11 algorithms combining WISC-IV subtest raw scores with demographic variables. The CPIE was applied to a sample of children with acquired traumatic brain injury (TBI sample; n = 40) and a healthy demographically matched sample (n = 40). Paired-samples t tests found estimated premorbid FSIQ differed from obtained FSIQ when applied to the TBI sample (ps <or= .01). When applied to healthy peers, estimated and obtained FSIQ did not differ (ps > .02). The demographic only algorithm performed well at a group level, but estimates were restricted in range. Algorithms combining single subtest scores with demographics performed adequately. Results support the clinical application of the CPIE algorithms. However, limitations to estimating individual premorbid ability, including statistical and developmental factors, must be considered.
神经心理损伤的测定涉及将所获得的表现与一个比较标准进行对比，该标准通常是病前智商的估计值。M. R. 舍恩伯格、R. T. 兰格、T. A. 布里克尔和D. H. 萨克洛夫斯基（2007年）提出了儿童病前智力估计（CPIE），以使用韦氏儿童智力量表第四版（WISC-IV；韦克斯勒，2003年）来预测病前全量表智商（FSIQ）。CPIE包括12种预测FSIQ的算法，1种使用人口统计学变量，11种算法将WISC-IV子测验原始分数与人口统计学变量相结合。CPIE被应用于一组获得性创伤性脑损伤儿童样本（TBI样本；n = 40）和一个在人口统计学上匹配的健康样本（n = 40）。配对样本t检验发现，当应用于TBI样本时，估计的病前FSIQ与获得的FSIQ不同（p值≤0.01）。当应用于健康同龄人时，估计的和获得的FSIQ没有差异（p值>0.02）。仅使用人口统计学的算法在组水平上表现良好，但估计范围有限。将单个子测验分数与人口统计学相结合的算法表现良好。结果支持CPIE算法的临床应用。然而，必须考虑估计个体病前能力的局限性，包括统计和发育因素。
