We examined the responsiveness to a 12-week phonics intervention in 54 s-grade Dutch children with dyslexia, and compared their reading and spelling gains to a control group of 61 typical readers. The intervention aimed to train grapheme-phoneme correspondences (GPCs), and word reading and spelling by using phonics instruction. We examined the accuracy and efficiency of grapheme-phoneme correspondences, decoding words and pseudowords, as well as the accuracy of spelling words before and after the intervention. Moreover, responsiveness to intervention was examined by studying to what extent scores at posttest could directly or indirectly be predicted from precursor measures. Results showed that the children with dyslexia were significantly behind in all reading and spelling measures at pretest. During the intervention, the children with dyslexia made more progress on GPC, (pseudo)word decoding accuracy and efficiency, and spelling accuracy than the typical reading group. Furthermore, we found a direct effect of the precursor measures rapid automatized naming, verbal working memory and phoneme deletion on the dyslexic children's progress in GPC speed, and indirect effects of rapid automatized naming and phoneme deletion on word and pseudoword efficiency and word decoding accuracy via the scores at pretest.

我们对54名患有诵读困难的荷兰小学低年级儿童进行了一项为期12周的自然拼读干预反应性研究，并将他们在阅读和拼写方面的进步与61名普通阅读者组成的对照组进行了比较。该干预旨在通过自然拼读教学来训练音素对应关系（GPC）以及单词阅读和拼写能力。我们考察了干预前后音素对应关系、解码单词和假词的准确性和效率，以及拼写单词的准确性。此外，通过研究后测分数在多大程度上可以从前驱测量指标直接或间接预测，来考察干预反应性。结果显示，患有诵读困难的儿童在预测试中的所有阅读和拼写测量指标上都明显落后。在干预过程中，患有诵读困难的儿童在GPC、（假）词解码准确性和效率以及拼写准确性方面比普通阅读组取得了更大的进步。此外，我们发现前驱测量指标快速自动命名、言语工作记忆和音素删除对诵读困难儿童在GPC速度方面的进步有直接影响，并且快速自动命名和音素删除通过预测试分数对单词和假词效率以及单词解码准确性有间接影响。版权所有© 2016约翰威立父子有限公司。
