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:

This is a revised version of the macro. The version included with the paper contains errors. We sincerely apologize for the inconvenience.

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 WAB.
Here is a version of the QAB that includes extended forms for when more time is available.

Several SLPs and researchers have expressed an interest in translating or adapting the QAB for other languages.

We are glad to host completed adaptations here if you would like to make them available to others.
