检查以标准化方式管理的词汇测试与使用脑机接口（BCI）管理的版本之间的测量一致性。样本由21名参与者组成，年龄9-27岁，平均年龄16.7（5.4）岁，61.9%为男性，包括10名先天性痉挛性脑瘫（CP）患者和11名对照同龄人。参与者完成了皮博迪图片词汇测试-4（PPVT™-4）的标准版本和BCI辅助的替代版本。BCI促进的PPVT-4使用与未修改的PPVT-4相同的项目，但每个象限迫选项目都呈现在计算机屏幕上，以与BCI一起使用。仪器之间的测量一致性非常好，包括0.98的类内相关系数，Bland-Altman图和检验表明一致性有足够的限度，无系统性检验版本偏倚。测试版本之间的平均标准分差异为2.0分（SD 6.3）。这些结果表明，BCI促进象限强迫选择词汇测试有潜力来衡量语言的各个方面，而不需要任何明显的身体或交际反应。因此，有可能确定许多没有获得标准化临床和研究工具的人的语言能力和需求。
To examine measurement agreement between a vocabulary test that is administered in the standardized manner and a version that is administered with a brain-computer interface (BCI). The sample was comprised of 21 participants, ages 9–27, mean age 16.7 (5.4) years, 61.9% male, including 10 with congenital spastic cerebral palsy (CP), and 11 comparison peers. Participants completed both standard and BCI-facilitated alternate versions of the Peabody Picture Vocabulary Test - 4 (PPVT™-4). The BCI-facilitated PPVT-4 uses items identical to the unmodified PPVT-4, but each quadrant forced-choice item is presented on a computer screen for use with the BCI. Measurement agreement between instruments was excellent, including an intra-class correlation coefficient of 0.98, and Bland-Altman plots and tests indicating adequate limits of agreement and no systematic test version bias. The mean standard score difference between test versions was 2.0 points (SD 6.3). These results demonstrate that BCI-facilitated quadrant forced-choice vocabulary testing has the potential to measure aspects of language without requiring any overt physical or communicative response. Thus, it may be possible to identify the language capabilities and needs of many individuals who have not had access to standardized clinical and research instruments.
