The Word Accentuation Test (WAT, Spanish adaptation of the NART) and the Pseudo-Words (PW) Reading subtest from the Battery for Reading Processes Assessment-Revised (PROLEC-R) are measures to estimate premorbid IQ. This study aims to develop demographically calibrated norms for these premorbid measures in a representative sample of the adult Spanish population in terms of age, education, and sex. A sample of 700 healthy participants from 18 to 86 years old completed the WAT and the PW Reading subtest. The effect of age, years of formal education, and sex on WAT total score, PW total score, and time to complete the PW task (PW time) were analyzed. Percentiles and scalar scores were obtained for each raw score according to nine age ranges and individual education levels. The results indicated a significant effect of age and education on the premorbid performance assessed, with no significant effect of sex. Age and education explained from 1.9 to 33.2% of the variance in premorbid IQ variables. Older participants with fewer years of education obtained worse premorbid IQ estimates. This premorbid IQ estimation decline started in the 56-65 age range for WAT total score and PW time, whereas it started in the 71-75 age range for PW total score. This study reports the first demographic-calibrated norms for WAT and PW Reading subtest for Spanish-speaking population. Even though the influence of age and years of education on premorbid IQ measures was confirmed, the PW Reading subtest showed to be more resistant to decline in elderly population than the WAT.
单词重音测试（WAT，西班牙语版的国民阅读能力测试）以及阅读过程评估修订版电池组（PROLEC-R）中的伪词（PW）阅读子测试是用于估计病前智商的测量方法。本研究旨在针对西班牙成年人口的一个具有代表性的样本，根据年龄、教育程度和性别，制定这些病前测量方法的人口统计学校准常模。700名年龄在18至86岁之间的健康参与者完成了WAT和PW阅读子测试。分析了年龄、正规教育年限和性别对WAT总分、PW总分以及完成PW任务时间（PW时间）的影响。根据九个年龄范围和个人教育水平，为每个原始分数获得了百分位数和标度分数。结果表明，年龄和教育程度对所评估的病前表现有显著影响，而性别没有显著影响。年龄和教育程度解释了病前智商变量中1.9%至33.2%的方差。受教育年限较少的老年参与者获得的病前智商估计值较差。这种病前智商估计值的下降在WAT总分和PW时间方面始于56 - 65岁年龄范围，而在PW总分方面始于71 - 75岁年龄范围。本研究报告了首个针对讲西班牙语人群的WAT和PW阅读子测试的人口统计学校准常模。尽管年龄和教育年限对病前智商测量的影响得到了证实，但PW阅读子测试在老年人群中显示出比WAT更能抵抗下降。
