This research was carried out according to the Italian Consensus Conference on Specific Learning Disability guidelines for screening initiatives. It describes a three-year screening project involving 2.469 students, aged 8-15 years, from various classes of primary, lower and upper secondary schools of Sicily. Students were assessed for reading and spelling skills. Overall, 4.9% met the risk criteria for suspected reading disorder, 6.1% for spelling disorder, while 8.5% for both conditions. Results showed that out of 932 pupils in the primary school, 4.6% met the risk criteria for reading disorder and 6.5% for spelling disorder; out of 855 pupils of the lower secondary school, 5.3% for reading disorder and 5.5% for spelling disorder; out of 652 pupils of the upper secondary school, 4.9% for reading disorder and 6.1% for spelling disorder. No significant difference in the prevalence of students at risk of reading disorder or spelling disorder, within the three grade-levels over 3 years, was found. At project conclusion further clinical investigation to verify the screening results on student sub-sample (57%) was carried out. The percentage of students with SLD was equal to 3.15%, in the primary school, 3.76% in the lower secondary school and 2.51%, in the upper secondary school.
本研究按照意大利特定学习障碍共识会议的筛查标准进行。它描述了一个为期三年的筛查项目，涉及来自西西里岛不同小学、初中和高中班级的 2469 名 8-15 岁的学生。学生的阅读和拼写技能接受了评估。总体而言，有 4.9%的学生符合疑似阅读障碍的风险标准，6.1%的学生符合拼写障碍的风险标准，8.5%的学生同时符合这两种障碍的风险标准。结果表明，在 932 名小学生中，有 4.6%的学生符合阅读障碍的风险标准，6.5%的学生符合拼写障碍的风险标准；在 855 名初中生中，有 5.3%的学生符合阅读障碍的风险标准，5.5%的学生符合拼写障碍的风险标准；在 652 名高中生中，有 4.9%的学生符合阅读障碍的风险标准，6.1%的学生符合拼写障碍的风险标准。在 3 年的时间里，没有发现三个年级学生的阅读障碍或拼写障碍风险发生率存在显著差异。在项目结束时，对学生子样本（57%）进行了进一步的临床调查，以验证筛查结果。在小学、初中和高中，SLD 学生的比例分别为 3.15%、3.76%和 2.51%。
