Özet

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 (alpha = 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.
