The Quick Aphasia Battery (QAB) aims to provide a reliable and multidimensional assessment of language function in about a quarter of an hour, bridging the gap between comprehensive batteries that are time-consuming to administer, and rapid screening instruments that provide limited detail regarding individual profiles of deficits. The QAB is made up of eight subtests, each comprising sets of items that probe different language domains, vary in difficulty, and are scored with a graded system to maximize the informativeness of each item. From the eight subtests, eight summary measures are derived, which constitute a multidimensional profile of language function, quantifying strengths and weaknesses across core language domains. In a norming study, we have shown that the QAB efficiently and reliably characterizes individual profiles of language deficits. To remove barriers to adoption of cost or convenience, we have made available here all materials required to administer the QAB.
The QAB is described in detail in the following open access paper:
An extended version of the QAB that includes additional items, for situations where more time is available.
A version of the QAB for remote administration, e.g. by Zoom.

Many clinicians have asked whether QAB scores can be interpreted in terms of severity. We emphasize that severity terms are arbitrary, but recognizing the need for this in clinical practice, we suggest the following guidelines:
|QAB overall score||Severity|
These cutoffs are based on the documented correspondence between the QAB and the Western Aphasia Battery.
