Estimation of premorbid IQ is useful for estimating true cognitive decline in dementia. The National Adult Reading Test-NART (Nelson, 1982)-has been shown to estimate premorbid IQ in hospital patients. NART is potentially of use in epidemiological studies. However, asking community elderly people to read a list of irregular and difficult words can cause distress. This paper explores the possibility of administering only a part of the NART. On the basis of scores on the first half of the test from an elderly rural community sample (N = 316), a regression equation has been developed to predict performance on the second half of the test. It was built using the scores of half the population free from clinical diagnoses and tested on the other half. It was also applied to a demented group and a depressed group from the same population. Total NART scores predicted in this way were highly significantly correlated with the actual NART score for all groups. Recommendations about the use of this shortened test are made.
病前智商的估计对于评估痴呆症患者真正的认知衰退很有用。国家成人阅读测验（NART）（Nelson，1982年）已被证明可用于估计住院患者的病前智商。NART在流行病学研究中可能有用。然而，要求社区老年人阅读一系列不规则且难的单词可能会让他们感到苦恼。本文探讨了只进行部分NART测试的可能性。基于一个农村老年社区样本（N = 316）前半部分测试的分数，已经开发出一个回归方程来预测后半部分测试的表现。该方程是使用一半无临床诊断人群的分数建立的，并在另一半人群上进行了测试。它还被应用于来自同一人群的痴呆组和抑郁组。以这种方式预测的NART总分与所有组的实际NART分数高度显著相关。文中给出了关于使用这种简化测试的建议。
