In this paper we present data on the prevalence of speech problems in a nationally representative group of children according to three modes of assessment. There was a large measure of disagreement between the assessments. Sex, social class, birth order and family size differences were examined. There was indirect evidence to suggest that the social class differences in the teacher's assessments of poor speech could be explained in terms of differences in children's dialect and language rather than a reflection of speech deficits. Finally we examined the relationship between parental assessment and the three modes of assessment. Overall, the degree of concurrence was low.
在本文中，我们根据三种评估方式，呈现了一组具有全国代表性的儿童言语问题患病率的数据。这些评估之间存在很大程度的分歧。我们研究了性别、社会阶层、出生顺序和家庭规模差异。有间接证据表明，教师对言语不佳的评估中存在的社会阶层差异，可以用儿童方言和语言的差异来解释，而不是反映言语缺陷。最后，我们研究了家长评估与这三种评估方式之间的关系。总体而言，一致性程度较低。
