Two cohorts of 4- and 5-year-old children (N = 700) were screened with the Fluharty Preschool Speech and Language Screening Test. Two stratified samples (n = 51 cohort 1; n = 147 cohort 2), based on speech/language screening results, were administered criterion tests for articulation (AAPS-R or Templin-Darley) and language (TOLD or TALC-R). Clinical validation indices for combined speech or language outcome in the two cohorts were as follows: sensitivity, .43 and .31 respectively; specificity, .82 and .93; predictive value, .43 and .54; overreferral, 14% and 5%; underreferral, 14% in both cohorts, and percent agreement, 72% and 80%. The measure of sensitivities for language outcomes was lower than the above, whereas sensitivities for articulation was higher. These results suggest that the Fluharty is too insensitive to be relied on for screening programs aimed at identifying preschool children with language disorders, although it appears to have promise for the identification of children with articulation impairments.
两组4岁和5岁儿童（N = 700）接受了弗拉哈蒂学前语言筛查测试。根据语言筛查结果，从两组中选取了两个分层样本（队列1为n = 51；队列2为n = 147），对其进行了发音（AAPS-R或坦普林-达利测试）和语言（TOLD或TALC-R）的标准测试。两个队列中言语或语言综合结果的临床验证指标如下：敏感性分别为0.43和0.31；特异性分别为0.82和0.93；预测值分别为0.43和0.54；过度转诊率分别为14%和5%；漏诊率在两个队列中均为14%，一致性百分比分别为72%和80%。语言结果的敏感性测量低于上述水平，而发音的敏感性较高。这些结果表明，弗拉哈蒂测试对于旨在识别患有语言障碍的学龄前儿童的筛查项目来说过于不敏感，无法依赖，不过它似乎在识别有发音障碍的儿童方面有前景。
