A screening tool to detect stroke aphasia: Adaptation of frenchay aphasia screening test (FAST) to the Indian context

Background: Aphasia is a common consequence of stroke. To optimize recovery, it becomes critical as there are early identification and treatment of language deficits. The rising burden of stroke aphasia and lack of screening tools in the Indian context necessitates the need for a screening tool. Objective: We aimed to adapt and validate the Frenchay Aphasia Screening Test (FAST) to the Indian context in two widely spoken Indian languages, Telugu and Kannada, for the literate and illiterate population. Methods: A systematic process of adaptation and culturally appropriate modifications of the original FAST were done in 116 healthy controls and 115 patients. The validity of the adapted test was established. Results: The optimum cut-off values for detecting aphasia in our sample ranged from 25 to 25.5 (literate) and 13.5 to 15.5 (illiterate) with high sensitivity and specificity. There was also a significant correlation between aphasia scores for adapted FAST and the Western Aphasia Battery (WAB), establishing good convergent validity. Discussion: Results of the adaptation and validation of two Indian versions of FAST, suggest that it is an easy-to-use screening measure for detecting stroke-related language disabilities. The psychometric properties of the Indian version of FAST met the standardised requirements for adaptation and validation. Conclusions: The Indian version of FAST was found to be a reliable and valid bedside screening tool for aphasia in stroke patients. We aim that this study will facilitate the use of the test across other Indian languages and a large clinical population in the future.

一种检测中风失语症的筛查工具：法式失语症筛查测试 (FAST) 对印度环境的适应
背景：失语是中风的常见后果。为了优化恢复，早期识别和治疗语言缺陷变得至关重要。在印度，中风失语症负担的增加和筛查工具的缺乏使得筛查工具成为必要。目标：我们的目的是针对有识字和文盲的人群，以两种广泛使用的印度语言泰卢固语和卡纳达语调整和验证法式失语症筛查测试 (FAST)。方法：在 116 名健康对照者和 115 名患者中对原始 FAST 进行了系统的适应和文化上适当的修改。确定了改编测试的有效性。结果：在我们的样本中检测失语的最佳截止值范围为 25 至 25.5（识字）和 13.5 至 15.5（文盲），具有高灵敏度和特异性。适应 FAST 的失语评分与西方失语电池 (WAB) 之间也存在显着相关性，从而建立了良好的收敛效度。讨论：两个印度版本的 FAST 的改编和验证结果表明，它是一种易于使用的筛查措施，用于检测与中风相关的语言障碍。印度版 FAST 的心理测量特性符合适应和验证的标准化要求。结论：印度版的 FAST 被发现是一种可靠且有效的中风患者失语症床边筛查工具。我们的目标是，这项研究将促进未来在其他印度语言和大量临床人群中使用该测试。
