The purpose of this study was to develop a short form of the Boston Naming Test (BNT; Kaplan, Goodglass, & Weintraub, 2001) for individuals with aphasia and compare it with 2 existing short forms originally analyzed with responses from people with dementia and neurologically healthy adults.
Development of the new BNT-Aphasia Short Form and analysis of the other 2 forms were completed with archival data from 100 individuals with aphasia. The authors developed the BNT-Aphasia Short Form using items from the original 60-item instrument based on item response theory. Rasch analysis was computed on the short forms developed by Graves, Bezeau, Fogarty, and Blair (2004) and by Mack, Freed, Williams, and Henderson (1992).
Analysis of the Graves et al. (2004) short form resulted in the smallest range of item difficulty and the largest floor effect compared with the Mack et al. (1992) short form and the BNT-Aphasia short form. The BNT-Aphasia Short Form showed an increase in information in the middle of the scale relative to both the Graves et al. and the Mack et al. forms.
The new short form demonstrates good psychometric properties when used with individuals with aphasia. However, the Mack et al. form proved to be as psychometrically sound as the BNT-Aphasia Short Form and is also appropriate for individuals with aphasia.
本研究旨在为失语症患者开发波士顿命名测试（BNT；Kaplan、Goodglass 和 Weintraub，2001）的简短形式，并将其与另外 2 种原本使用痴呆症和神经健康成年人的反应进行分析的简短形式进行比较。
使用 100 名失语症患者的档案数据完成了新的 BNT-失语症简短形式的开发和另外 2 种形式的分析。作者根据项目反应理论，使用原始 60 项测试中的项目开发了 BNT-失语症简短形式。Rasch 分析计算了 Graves、Bezeau、Fogarty 和 Blair（2004 年）以及 Mack、Freed、Williams 和 Henderson（1992 年）开发的简短形式。
与 Mack 等人（1992 年）的简短形式和 BNT-失语症简短形式相比，Graves 等人（2004 年）的简短形式分析结果表明项目难度范围最小，地板效应最大。BNT-失语症简短形式在量表中间显示出信息增加，相对于 Graves 等人和 Mack 等人的形式都是如此。
新的简短形式在用于失语症患者时表现出良好的心理测量特性。然而，Mack 等人的形式证明与 BNT-失语症简短形式一样具有心理测量上的合理性，并且也适用于失语症患者。
