Cluster randomised control trial of an early childhood literacy intervention to improve literacy and language outcomes in preschool aged children

阅读障碍对澳大利亚弱势群体的影响不成比例，近40%的贫困儿童在三年级时未能达到最低阅读基准。更令人担忧的是，一个令人不安的趋势表明，在一年级之前，社会经济地位(SES)的差异也存在于阅读的重要先行因素中，例如字母知识和语音处理技能，但仍然没有在初级保健环境中促进早期语言和识字实践的普遍计划。我们提出了一项整群随机对照试验，以评估多次注射干预改善弱势社区儿童识字结果的有效性。

Reading failure disproportionately affects disadvantaged communities in Australia, with nearly 40% of poor children failing to read at the minimum reading benchmark in Grade three. Of more concern is the disturbing trend indicating that prior to first grade, socioeconomic status (SES) differences also exist in important antecedents of reading such as letter knowledge and phonological processing skills, yet there remains no universal program to promote early language and literacy practices in the primary care setting. We propose a cluster randomised controlled trial to evaluate the efficacy of a multi injection intervention to improve literacy outcomes of children in disadvantaged communities.
