A complete battery and a bedside instrument to quickly diagnose moderate to severe aphasia
Maintains structure, content and clinical value with key improvements
The Western Aphasia Battery–Revised (WAB–R) is the updated version of the highly respected and widely used instrument for assessing adult patients with aphasia. It is an individually administered assessment for adults with acquired neurological disorders (e.g., as a result of stroke, head injury, dementia). Like the previous edition, WAB–R assesses the linguistic skills most frequently affected by aphasia, in addition to key nonlinguistic skills, and provides differential diagnosis information.
New Features Mean Enhanced Utility
The WAB–R, a full battery of 8 subtests (32 short tasks), maintains the structure and overall content and clinical value of the current measure while creating these improvements:
- Two new supplementary tasks (reading and writing of irregular and non-words) will aid the clinician in distinguishing between surface, deep (phonological), and visual dyslexia.
- Revision of approximately 15 items
- Bedside WAB–R – provides a quick look at patient’s functioning
- Examiner’s manual with technical/psychometric properties information, test interpretation relevant to aphasic populations, historical evidence of reliability and validity, and information about the unique aspects of assessing the language ability of individuals with dementia
- Spiral-bound stimulus book replacing loose stimulus cards
- Revised administration directions – more user-friendly with directions to the examinee for all subtests
- Expanded scoring guidelines for clarity
How Is It Scored?
Criterion cut scores:
- Aphasia Quotient
- Cortical Quotient
- Auditory Comprehension Quotient
- Oral Expression Quotient
- Reading Quotient
- Writing Quotient
- Bedside WAB–R scores
What Does the WAB-R Do?
Frequently asked questions follow. Click on a question to see the response.
When a customer is interpreting a Bedside WAB-R score there aren’t severity descriptors like there are for the AQ on page 83, right? On page 84, it states, “Interpretation of the sections and tasks are consistent with the full test”.
Based on the author’s expertise, the Bedside Aphasia Score should correlate to the full diagnostic test’s Aphasia Quotient. If this is true, then the Bedside Aphasia Score can be interpreted using the severity ratings supplied for the Aphasia Quotient; however, the severity rating obtained using the Beside Aphasia Score can only be interpreted as an indicator of the severity rating that could be expected if the full test was administered and an Aphasia Quotient obtained.
