To develop and validate 28 short Italian sentences for the construction of the Italian version of the Radner Reading Chart to simultaneously measure near visual acuity and reading speed.
41 sentences were constructed in Italian language, following the procedure defined by Radner, to obtain "sentence optotypes" with comparable structure and with the same lexical and grammatical difficulty. Sentences were statistically selected and used in 211 normal, non-presbyopic, native Italian-speaking persons. The most equally matched sentences in terms of reading speed and number of reading errors were selected. To assess the validity of the reading speed results obtained with the 28 selected short sentences, we compared the reading speed and reading errors with the average obtained by reading two long 4th-grade paragraphs (97 and 90 words) under the same conditions.
The overall mean reading speed of the tested persons was 189±26wpm. The 28 sentences more similar in terms of reading times were selected, achieving a coefficient of variation (the relative SD) of 2.2%. The reliability analyses yielded an overall Cronbach's alpha coefficient of 0.98. The correlation between the short sentences and the long paragraph was high (r=0.85, P<0.0001).
The 28 short single Italian sentences optotypes were highly comparable in syntactical structure, number, position, and length of words, lexical difficulty, and reading length. The resulting Italian Radner Reading Chart is precise (high consistency) and practical (short sentences) and therefore useful for research and clinical practice to simultaneously measure near reading acuity and reading speed.
开发并验证28个意大利语短句，用于构建意大利语版拉德纳阅读图表，以同时测量近视力和阅读速度。
按照拉德纳定义的程序，用意大利语构建了41个句子，以获得结构可比、词汇和语法难度相同的“句子视标”。对句子进行统计学筛选，并在211名正常、非老花眼、以意大利语为母语的人群中使用。选择了阅读速度和阅读错误数量最匹配的句子。为评估用28个选定短句获得的阅读速度结果的有效性，我们将阅读速度和阅读错误与在相同条件下阅读两段四年级长段落（97和90个单词）的平均结果进行了比较。
受测者的总体平均阅读速度为189±26词/分钟。选择了阅读时间最相似的28个句子，变异系数（相对标准差）为2.2%。可靠性分析得出总体克朗巴哈α系数为0.98。短句与长段落之间的相关性很高（r = 0.85，P < 0.0001）。
28个简短的意大利语单句视标在句法结构、单词数量、位置和长度、词汇难度以及阅读长度方面具有高度可比性。由此产生的意大利语拉德纳阅读图表精确（高度一致性）且实用（短句），因此对于同时测量近阅读视力和阅读速度的研究及临床实践很有用。
