The relationship between NART performance and demographic variables was examined in a group of subjects free of neurologic or psychiatric disorder (n = 201). NART estimated IQ was significantly correlated with education, social class and age. The correlation between age and NART IQ was no longer significant after partialling out either education or social class. There was no evidence of a curvilinear relationship between age and NART performance. There was no significant sex difference in NART performance. Nelson's (1982) report of a high split-half reliability was confirmed.
在一组无神经或精神疾病的受试者（n = 201）中，研究了国家成人阅读测验（NART）成绩与人口统计学变量之间的关系。NART估计智商与教育程度、社会阶层和年龄显著相关。在剔除教育程度或社会阶层因素后，年龄与NART智商之间的相关性不再显著。没有证据表明年龄与NART成绩之间存在曲线关系。NART成绩在性别上没有显著差异。证实了纳尔逊（1982年）关于高折半信度的报告。
