ABSTRACT

Practices for the evaluation and treatment for people with aphasia (PWA) is dominated by an impairment-based view of aphasia. The number of aphasia evaluation tools adapted or developed to reflect PWA’s perspective in Turkish is limited. Aphasia Impact Questionnaire-21 (AIQ-21), a tool developed based on the social model of disability, measures the individuals’ quality of life from their own perspective. This study sought to adapt and establish the validity and reliability of AIQ-21 in Turkish (AIQ-21-TR) to meet this need. Data from 43 PWA and 61 healthy participants were analysed to determine AIQ-21-TR’s construct, criterion, face validity and content validity. Reliability of the scale was assessed using Cronbach’s Alpha reliability coefficients and the inter-item and item-total score correlations coefficients. Correlation between AIQ-21-TR and Stroke and Aphasia Quality of Life Scale-39 Turkish (SAQOL-39-TR) was also calculated. The validity analysis indicated that the Turkish adaptation of AIQ-21 has a high level of construct, content, face, and criterion validity. Similarly, the reliability analysis showed that the adapted questionnaire has an excellent reliability coefficient (α = 0.91). Our findings suggested that AIQ-21-TR may be used as a reliable and valid tool with PWA in clinical and research settings.

摘要

失语症患者 (PWA) 的评估和治疗实践以基于障碍的失语症观点为主。为反映 PWA 在土耳其语中的观点而改编或开发的失语症评估工具的数量是有限的。Aphasia Impact Questionnaire-21 (AIQ-21) 是一种基于残疾社会模型开发的工具，它从个人的角度衡量个人的生活质量。本研究旨在调整并确定 AIQ-21 土耳其语 (AIQ-21-TR) 的有效性和可靠性，以满足这一需求。分析了来自 43 名 PWA 和 61 名健康参与者的数据，以确定 AIQ-21-TR 的结构、标准、表面效度和内容效度。使用 Cronbach 的 Alpha 信度系数以及项目间和项目总分相关系数评估量表的信度。还计算了 AIQ-21-TR 与中风和失语症生活质量量表 39 土耳其语 (SAQOL-39-TR) 之间的相关性。效度分析表明，土耳其语改编的 AIQ-21 在结构效度、内容效度、面子效度和标准效度上均具有较高水平。同样，信度分析表明，改编后的问卷具有出色的信度系数（α  = 0.91）。我们的研究结果表明，AIQ-21-TR 可用作临床和研究环境中 PWA 的可靠和有效工具。
