Beardsall & Brayne (1990) have introduced a method for estimating full-length National Adult Reading Test (NART) scores using the scores on the first half of the test only. They suggest that this is appropriate for subjects who are of low reading ability and might otherwise find testing distressing. Crawford, Parker, Allan, Jack & Morrison (1991) have subsequently explored the accuracy with which Short NART predicted full NART scores and in addition WAIS IQ scores in a large cross-validation sample. They concluded that the Short NART could be used with modest confidence when estimating premorbid IQ. However, when applied to 202 consecutive referrals to this Memory Disorders Clinic, the accuracy with which the Short NART predicted full NART error scores was less satisfactory. Results indicated that discrepancies between Short NART and full NART error scores were outside the bounds of both clinical and statistical acceptability. Examination of these results revealed that one possible source of difficulty lay in variation in the accuracy with which words are pronounced. It is concluded that, despite the appeal of a shortened version of the NART to estimate premorbid IQ, without further modification its use in clinical practice cannot be recommended.
比尔兹尔和布雷恩（1990年）介绍了一种仅使用测试前半部分的分数来估算全国成人阅读测试（NART）全长分数的方法。他们认为，这对于阅读能力较低、否则可能会觉得测试令人痛苦的受试者来说是合适的。克劳福德、帕克、艾伦、杰克和莫里森（1991年）随后在一个大型交叉验证样本中探讨了简短NART预测完整NART分数以及韦氏成人智力量表（WAIS）智商分数的准确性。他们得出结论，在估算病前智商时，可以适度放心地使用简短NART。然而，当将其应用于连续转诊至该记忆障碍诊所的202名患者时，简短NART预测完整NART错误分数的准确性就不那么令人满意了。结果表明，简短NART与完整NART错误分数之间的差异超出了临床和统计学可接受的范围。对这些结果的检查表明，一个可能的困难来源在于单词发音准确性的差异。得出的结论是，尽管缩短版NART在估算病前智商方面很有吸引力，但在未经进一步修改的情况下，不建议在临床实践中使用。
