Abstract：
The capacity to quickly verbalize words beginning with a specific letter is integral in assessing language skills as well as an essential part of a comprehensive neuropsychological assessment. Using the letters F, A, S as a word fluency measure is limited by having no direct parallel alternative that can use the same F, A, S norms. This observational and cross-sectional study examined the correlation between the Word Fluency Test (WFT), utilizing letters M, D, H, as a parallel alternative to the clinical standard F, A, S to determine if the two are equivalent. This would allow for the use of existing F, A, S norms. Study participants (N = 356) were comprised of both adult control participants and out-patients with normal neuropsychological test results. Between-group differences for both task performances were not statistically significant indicating that patients and controls performed similarly on each of the six letters. Between-letter correlations were moderate in strength indicating an acceptable level of agreement between all of the letters. The results confirm equivalency and support administering the WFT and employing F, A, S norms offering a corresponding parallel alternative measure with strong correlation indicating high level of agreement.
摘要：
快速以特定字母开头的单词的能力是评估语言技能不可或缺的一部分，也是全面神经心理学评估的重要组成部分。使用字母F，A,S作为单词流畅性度量受到没有可以使用相同F的直接并行替代方法的限制，A,S规范。这项观察性和横断面研究检查了单词流利度测试(WFT)和利用字母M，D,H,作为临床标准F的平行替代方案，A,S来确定两者是否相等。这将允许使用现有的F，A,S规范。研究参与者（N=356）由成年对照参与者和神经心理学测试结果正常的门诊患者组成。两种任务表现的组间差异均无统计学意义，表明患者和对照组在六个字母中的每个字母上的表现相似。字母之间的相关性强度适中，表明所有字母之间的一致性水平可接受。结果证实了等效性，并支持管理WFT和使用F，A,S规范提供了相应的平行替代措施，具有很强的相关性，表明协议水平很高。
