Normal children between 3 and 6 yrs old generated word and sentence messages for use in a pediatric speech intelligibility (PSI) test. Word materials did not differ as a function of chronological age (CA), vocabulary skills, or receptive language (RL) ability. Elicited sentence materials, however, did reflect differences in CA, vocabulary skills, and RL ability. To represent differences in the children's responses, two different types of test sentences, subsequently referred to as format I and format II sentences, were formed. Performance for format I and format II sentences was significantly different in normal children between 3 and 6 yrs old. Performance differences were related to CA and RL ability. However, performance for format I sentences in children with relatively low RL age and performance for format II sentences in children with relatively high RL age was equivalent. This observation yielded an algorithm that determines the sentence format as a function of a child's RL age in order to yield "language equivalent" norms for speech audiometry. In contrast to performance for PSI sentence materials, performance for PSI word materials was not influenced by differences in RL skill. Reliability coefficients for PSI word and sentence test-retest measures ranged from about 0.85 to 0.95 in normal-hearing and hearing-impaired children. Illustrative PSI results in children with confirmed central auditory disorders are presented.
3至6岁的正常儿童生成单词和句子信息，用于小儿言语可懂度（PSI）测试。单词材料并不因实际年龄（CA）、词汇技能或接受性语言（RL）能力而有所不同。然而，引出的句子材料确实反映了CA、词汇技能和RL能力的差异。为了体现儿童反应的差异，形成了两种不同类型的测试句子，随后称为I型和II型句子。3至6岁正常儿童中，I型和II型句子的表现存在显著差异。表现差异与CA和RL能力有关。然而，RL年龄相对较低的儿童中I型句子的表现与RL年龄相对较高的儿童中II型句子的表现相当。这一观察结果产生了一种算法，该算法根据儿童的RL年龄确定句子格式，以便为言语听力测定得出“语言等效”规范。与PSI句子材料的表现不同，PSI单词材料的表现不受RL技能差异的影响。在听力正常和听力受损的儿童中，PSI单词和句子重测测量的信度系数约为0.85至0.95。文中呈现了确诊为中枢听觉障碍儿童的典型PSI结果。
