OBJECTIVE Clarify procedures to correctly score Test of Premorbid Functioning (TOPF) and assess the accuracy of TOPF scores in the estimation of premorbid intellectual functioning. METHOD In this cross-sectional study, post-9/11 veterans (N = 233, 84.12% male) completed the TOPF, the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV), and performance validity measures. RESULTS All TOPF scores were significantly correlated with WAIS-IV FSIQ scores (range r = 0.56-.73). The degree of discrepancy between TOPF scores and FSIQ varied with 10%-17% of TOPF scores deviating from FSIQ scores by one SD or more. CONCLUSIONS Proper TOPF scoring procedures are presented. The TOPF Actual and Predicted scores were related to FSIQ. However, a higher percentage of Actual and Predicted scores were discrepant from FSIQ compared with the other three TOPF estimates, arguing against their use as independent premorbid estimates. Use of the TOPF as was designed is recommended.

病前功能测试：你做错了，但这重要吗？


目的 阐明正确评分病前功能测试 (TOPF) 的程序，并评估 TOPF 评分在估计病前智力功能方面的准确性。方法 在这项横断面研究中，9/11 事件后的退伍军人（N = 233，84.12% 为男性）完成了 TOPF、韦克斯勒成人智力量表第四版 (WAIS-IV) 和表现有效性测量。结果 所有 TOPF 分数均与 WAIS-IV FSIQ 分数显着相关（范围 r = 0.56-.73）。 TOPF 分数和 FSIQ 之间的差异程度各不相同，10%-17% 的 TOPF 分数与 FSIQ 分数偏离 1 个 SD 或更多。结论 提出了正确的 TOPF 评分程序。 TOPF 实际分数和预测分数与 FSIQ 相关。然而，与其他三个 TOPF 估计值相比，实际分数和预测分数与 FSIQ 存在差异的比例较高，因此反对将其用作独立的病前估计值。建议按设计使用 TOPF。
