An individual's reading ability cannot be reliably predicted from his/her letter acuity, contrast sensitivity, and visual field extent. We developed a set of Chinese reading acuity charts (C-READ) to assess the reading ability of Chinese readers, based on the collective wisdom of previously published reading acuity charts, especially the MNRead and the Radner Reading Charts.
The C-READ consists of three charts. Each consists sixteen 12-character simplified Chinese sentences crafted from first- to third-grade textbooks. One hundred eighteen native Chinese-speaking college students (aged 22.1 ± 2.1 years) with normal or corrected to normal near vision (-0.26 ± 0.05 logMAR) were included in the study to develop the C-READ charts, to test the homogeneity of the three charts, and to validate the C-READ against the text paragraphs from the International Reading Speed Texts (IReST) with corrected and uncorrected near vision.
The reading acuity, critical print size, and maximum reading speed for young normal native Chinese-speaking readers were 0.16 ± 0.05 logMAR, 0.24 ± 0.06 logMAR, and 273.44 ± 34.37 characters per minute (mean ± SD), respectively. The reliability test revealed no significant differences among the three C-READ charts and no significant test order effect in the three reading parameters. Regression analyses showed that the IReST reading speed could be reliably predicted by the C-READ maximum reading speed under the corrected near-vision condition (adjusted R = 0.72) and by C-READ maximum reading speed and critical print size under the uncorrected near-vision condition (adjusted R = 0.69).
The three C-READ charts are very comparable to each other, and there is no significant order effect. Reading test results can accurately predict continuous text reading performance quantified by the IReST reading speed over a wide range of refractive errors. The C-READ is a reliable and valid clinical instrument for quantifying reading performance in simplified Chinese readers.
个体的阅读能力无法通过其字母视力、对比敏感度和视野范围可靠地预测。我们基于先前发表的阅读视力表，尤其是MNRead和拉德纳阅读视力表的集体智慧，开发了一套中文阅读视力表（C-READ），以评估中文读者的阅读能力。
C-READ由三张视力表组成。每张视力表包含16个由一至三年级教科书精心挑选的12字简体中文句子。118名母语为中文的大学生（年龄22.1±2.1岁），其近视力正常或矫正后正常（-0.26±0.05 logMAR），被纳入本研究，用于开发C-READ视力表、测试三张视力表的同质性，并在矫正和未矫正近视力的情况下，对照国际阅读速度文本（IReST）中的文本段落验证C-READ。
年轻正常母语为中文的读者的阅读视力、临界印刷字体大小和最大阅读速度分别为0.16±0.05 logMAR、0.24±0.06 logMAR和每分钟273.44±34.37个字符（平均值±标准差）。可靠性测试显示，三张C-READ视力表之间无显著差异，且三个阅读参数中无显著的测试顺序效应。回归分析表明，在矫正近视力条件下，C-READ最大阅读速度可可靠地预测IReST阅读速度（调整后R = 0.72）；在未矫正近视力条件下，C-READ最大阅读速度和临界印刷字体大小可可靠地预测IReST阅读速度（调整后R = 0.69）。
三张C-READ视力表彼此非常可比，且无显著的顺序效应。阅读测试结果可以准确预测在广泛的屈光不正范围内，由IReST阅读速度量化的连续文本阅读表现。C-READ是一种可靠且有效的临床工具，用于量化简体中文读者的阅读表现。
