Turkish validity and reliability study on the quick aphasia battery.

All the study results show that QAB-TR has internal consistency, criterion validity, test-retest reliability, and inter-rater reliability. It can be administered in as little as 15 min and provides information about the multidimensional linguistic profiles of individuals. QAB-TR can be used for both clinical and study purposes as a language battery that allows for the measurement of the strengths and weaknesses of Turkish-speaking individuals who have suffered a stroke in basic language areas in acute and chronic periods. It can be easily administered at the bedside for individuals who have just suffered an acute stroke and can facilitate early assessment of individuals in terms of aphasia and early initiation of therapy, if necessary.
