Western Aphasia Battery - Scoring

Scoring

Criterion cut scores:

• Aphasia Quotient
• Cortical Quotient
• Auditory Comprehension Quotient
• Oral Expression Quotient
• Reading Quotient
• Writing Quotient
• Bedside WAB–R scores

The Western Aphasia Battery (Shewan & Kertesz, 1980) was designed to provide a means of evaluating the major clinical aspects of language function: content, fluency, auditory comprehension, repetition and naming plus reading, writing and calculation. In addition to the nonverbal skills of drawing, block design and praxis are evaluated and Raven's Colored Progressive Matrices test is usually administered as well. The scoring provides two main totals, in addition to the subscale scores. These are the Aphasia Quotient (AQ) score and Cortical Quotient (CQ) score. AQ can essentially be thought of as a measure of language ability, whilst CQ is a more general measure of intellectual ability and includes all the subscales. Administration of the Western Aphasia Battery (WAB) yields a total score termed the Aphasia Quotient (AQ), which is said to reflect the severity of the spoken language deficit in aphasia. This score is a weighted composite of performance on 10 separate WAB subtests.
