OBJECTIVE To examine whether Test of Premorbid Functioning (TOPF) and Wide Range Achievement Test-Word Reading subtest (WRAT WR) are interchangeable measures, and the relationship between these measures and intelligence, among patients with schizophrenia. METHOD In this archival study, the authors examined neuropsychology referrals of an inpatient forensic state hospital. Patients with a schizophrenia spectrum disorder (SSD) who received the Wechsler Adult Intelligence Scale-Fourth Edition or the Wechsler Abbreviated Scale of Intelligence-Second Edition and either TOPF or WRAT WR were considered for inclusion. The final sample consisted of 119 individuals (73.1% male). RESULTS Although there was a linear relationship between most TOPF variables and WRAT WR, their concordance was weak (concordance correlation coefficients [CCC] < 0.90). Poor concordance was also observed between current FSIQ and all standard scores (SS) derived from word reading measures. FSIQ-word reading measure discrepancy scores differed significantly from a hypothesized mean of 0 (mean discrepancy range = -7.42 to -16.60). Discrepancies greater than one standard deviation (>1 SD) were highest among demographics-based SS (i.e. TOPF Predicted and Simple without TOPF). Performance-based SS, particularly TOPF Actual and WRAT4 WR, had the fewest discrepancy scores >1 SD fromFSIQ. CONCLUSIONS TOPF and WRAT WR should not be used interchangeably among institutionalized patients with SSDs. TOPF and WRAT WR were discrepant from FSIQ, with demographic variables producing higher SS relative to performance-based variables. Future research is needed to determine which of these measures more accurately estimates intelligence among inpatients withSSDs.

TOPF 和 WRAT WR 在精神科住院患者中是否可以互换？

目的 研究精神分裂症患者的病前功能测试 (TOPF) 和宽范围成就测试单词阅读子测试 (WRAT WR) 是否是可互换的测量方法，以及这些测量方法与智力之间的关系。方法 在这项档案研究中，作者检查了一家住院法医医院的神经心理学转诊。接受韦氏成人智力量表第四版或韦氏智力缩写量表第二版和 TOPF 或 WRAT WR 的精神分裂症谱系障碍 (SSD) 患者被考虑纳入。最终样本由 119 人（73.1% 男性）组成。结果 尽管大多数 TOPF 变量和 WRAT WR 之间存在线性关系，但它们的一致性很弱（一致性相关系数 [CCC] < 0.90）。在当前的 FSIQ 和从单词阅读测量得出的所有标准分数 (SS) 之间也观察到了较差的一致性。FSIQ 单词阅读测量差异分数与假设的平均值 0 显着不同（平均差异范围 = -7.42 到 -16.60）。在基于人口统计的 SS（即 TOPF 预测和没有 TOPF 的简单）中，大于一个标准差 (>1 SD) 的差异最高。基于性能的 SS，尤其是 TOPF Actual 和 WRAT4 WR，与 FSIQ 的差异得分最少 > 1 SD。结论 TOPF 和 WRAT WR 不应在机构化的 SSD 患者中互换使用。TOPF 和 WRAT WR 与 FSIQ 存在差异，人口统计变量相对于基于绩效的变量产生更高的 SS。
