Children with speech difficulties form the largest group of those referred to children?s speech and language therapy departments. Though some children grow out of their difficulties, others have persistent problems that can affect their educational progress and social development. Previous research into children?s speech impairments has been unable to agree on the percentage of the population who are affected by this. In addition, a number of factors such as intelligence and family factors have been found to be associated with speech impairment though there is no conclusive agreement on which factors are most important. Similarly, the degree to which educational and social development is affected is in dispute. Some speech impairments are associated with anatomical or neurological impairments such as cleft palate or cerebral palsy, but for a large number of children, there is no identifiable cause. Research has suggested many possibilities and it is also thought that different subgroups may exist. Some of the research on speech impairments is now outdated and uses definitions of speech impairment that are no longer accepted. With the more recent studies, there has been a tendency to use small samples of children, in some instances just one or two cases. There is therefore an urgent need for population-based research.The Avon Longitudinal Study of Parents and Children (ALSPAC) is a large scale study of children?s development which has collected information on children?s speech development at ages 2, 5 and 8. This provides a unique opportunity to investigate some of the questions surrounding speech impairment. The proposed study will identify the percentage of children aged 5 and 8 years who have speech impairments, what factors predict persistent problems and what factors are associated with a good prognosis . It will identify outcomes for children with speech impairments and investigate the existence of any subgroups. The researcher team have considerable expertise in the field of children?s speech impairment as well as being familiar with the data collected in the ALSPAC study.Findings from this study will support the early identification of children at risk of persisting speech impairments and help to identify interventions which may prevent long term negative outcomes. In addition, a clear understanding of the numbers affected by these difficulty together with information on the factors which are associated with it, will enable services to be planned more effectively and resources targeted where they are most needed.

有语言障碍的儿童构成了被称为儿童的最大群体？的言语和语言治疗部门。虽然有些孩子长大后摆脱了他们的困难，但另一些孩子却有持续的问题，这些问题可能会影响他们的教育进步和社会发展。以前对儿童的研究？的语言障碍一直无法就受此影响的人口比例达成一致。此外，一些因素，如智力和家庭因素已被发现与语言障碍有关，但没有最重要的因素是最后的协议。同样，教育和社会发展受到影响的程度也存在争议。一些言语障碍与解剖学或神经学障碍有关，如腭裂或脑瘫，但对于大量儿童来说，没有可识别的原因。研究提出了许多可能性，也认为可能存在不同的亚组。一些关于语言障碍的研究现在已经过时，使用的语言障碍定义不再被接受。随着最近的研究，有一种倾向是使用小样本的儿童，在某些情况下只有一个或两个案例。因此，迫切需要以人群为基础的研究。雅芳家长和儿童纵向研究（ALSPAC）是一个大规模的儿童研究？的发展，收集有关儿童的资料？在2岁、5岁和8岁时的语言发展。这提供了一个独特的机会来调查一些问题周围的语言障碍。这项拟议中的研究将确定5岁和8岁儿童中有语言障碍的百分比，哪些因素预测了持续的问题，以及哪些因素与良好的预后有关。它将确定有语言障碍的儿童的结果，并调查任何亚组的存在。研究团队在儿童领域有相当的专业知识？本研究的结果将支持早期识别存在持续性言语障碍风险的儿童，并有助于识别可能预防长期不良后果的干预措施。此外，清楚了解受这些困难影响的人数以及与之相关的因素，将有助于更有效地规划服务，并将资源用于最需要的地方。
