The Urdu Quick Aphasia Battery exhibits promising preliminary validity and reliability for assessing language performance in Urdu-speaking stroke patients, with excellent content validity indices, an AUC of 0.96, and high reliability coefficients, though further validation with larger clinical samples is required before establishing its diagnostic utility.
Content validity indices for the Urdu Quick Aphasia Battery were excellent across all items.
The Urdu Quick Aphasia Battery demonstrated significant group differences between aphasia and non-aphasia participants across all subtests, supporting known group validity.
Preliminary Receiver Operating Characteristic analysis indicated strong diagnostic performance of the Urdu Quick Aphasia Battery.
The Urdu Quick Aphasia Battery demonstrated high inter-rater reliability.
Test-retest reliability of the Urdu Quick Aphasia Battery was high.
Internal consistency of the Urdu Quick Aphasia Battery was high.
There was no significant difference in performance across parallel forms of the Urdu Quick Aphasia Battery.
The adaptation process involved three phases including translation, validation, and reliability testing, with pilot testing conducted prior to the main validation study.
This research describes the translation, cultural adaptation, and initial testing of the Quick Aphasia Battery — a tool used to evaluate language abilities — into Urdu, for use with Pakistani stroke patients. Previously, no validated Urdu version existed, creating a gap in clinical assessment options for the large Urdu-speaking population. The researchers followed a structured three-phase process: first translating and culturally adapting the tool, then testing whether it could distinguish between people with and without aphasia (a language disorder often caused by stroke), and finally examining how consistent and reliable the results were across different raters and time points. The study found that the Urdu Quick Aphasia Battery performed well across multiple measures. It showed excellent content validity (meaning experts agreed it covered the right content), strong ability to differentiate between people with and without aphasia (AUC of 0.96, sensitivity of 86%, specificity of 92%), and very high reliability whether scored by different raters (ICC = 0.96), repeated at different time points (ICC = 0.98), or measured for internal consistency (Cronbach's α = 0.96). Parallel versions of the test also produced equivalent results. This research suggests that the Urdu Quick Aphasia Battery could be a useful clinical tool for assessing language problems in Urdu-speaking stroke patients, filling an important gap in neurological assessment resources for this population. However, the authors caution that the aphasia group in this study was small (only 7 individuals), so the diagnostic performance results are preliminary. Larger studies with more participants who have aphasia are needed before the tool can be fully recommended for routine clinical diagnosis.
