Seeing phonological disorders more clearly:

了解语音意识干预对语音障碍儿童语音系统的影响。语音障碍在儿童中的发生率约为7%，其中超过20%的儿童将患有一致性语音障碍(CPD)。通常，他们会接受语音意识(PA)干预，以提高他们的PA技能，并解决他们的一些语音产生错误。然而，患有慢性阻塞性肺疾病的儿童在PA干预后取得了不同程度的进展，有些是完全可以理解的，另一些仍然需要干预才能特别针对他们的慢性阻塞性肺病。这个项目的主要目的是发现是否存在可识别的CPD儿童亚群，他们对PA干预对他们表达音素的影响有不同的反应。首先，将完成系统的文献综述，以评估现有的PA方法治疗早期基础阶段SSD儿童的证据。其次，一项准实验小组研究将评估PA干预对CPD儿童言语声音系统的影响。多达50名3岁至5岁、11岁的CPD儿童将被招募，并在干预前、干预后和巩固后的三个阶段对PA、言语发音和接受性和表达语言的测量进行评估。所有参与者都将接受纽卡斯尔语音意识干预(NIPA)(Stringer，2019)，这是一种证据充分且广泛使用的PA干预措施。语音错误在三个评估阶段的变化将根据研究问题和确诊的CPD儿童亚组进行统计分析。该项目的结果将为SLT实践提供参考，以便更有效地有针对性地进行PA干预。

Understanding the impact of phonological awarenessintervention on the speech sound system of children withconsistent phonological disorder.The incidence of Speech Sound Disorder in children isapproximately 7%, of whom over 20% will have ConsistentPhonological Disorder (CPD). Typically they receivePhonological Awareness (PA) intervention to improve their PAskills and resolve some of their speech sound productionerrors. However, children with CPD make varying amounts ofprogress following PA intervention, some are completelyintelligible and others still require intervention to specificallytarget their CPD. The primary aim of this project is to discoverif there are identifiable subgroups of children with CPD whorespond differently to PA intervention in terms of its impact ontheir expressive phonology.Firstly, a systematic review of literature will be completed toassess existing evidence for PA approaches for Early YearsFoundation Stage children with SSD Secondly, a quasiexperimentalexperimental group study will evaluate theimpact of PA intervention on speech sound systems ofchildren with CPD. Up to 50 children with CPD aged 3;00 to5;11 will be recruited and assessed on measures of PA,speech sound production and receptive and expressivelanguage at three stages: pre-intervention, followingintervention, and after a consolidation period. All participantswill receive the Newcastle Intervention for PhonologicalAwareness (NIPA) (Stringer, 2019), a well-evidenced andwidely used PA intervention.Changes in speech sound errors over the three assessmentphases will be statistically analysed in relation to the researchquestions and subgroups of children with CPD identified.Results from this project will inform SLT practice, so that PAintervention can be more effectively targeted.
