Administration and Scoring
Administering the WAB Bedside involves a systematic approach to assess a patient’s language abilities. The test is typically conducted in a quiet environment, allowing the clinician to focus on the patient’s responses without distractions. The examiner begins by introducing themselves and explaining the purpose of the assessment to the patient in a clear and concise manner.
The WAB Bedside comprises several subtests, each designed to evaluate specific language skills. These subtests include tasks such as auditory comprehension, verbal fluency, repetition, naming, reading, and writing. The clinician presents each task according to the standardized instructions provided in the WAB Bedside manual. The patient’s performance is then recorded, noting both correct and incorrect responses.
Scoring the WAB Bedside involves assigning points based on the patient’s performance on each subtest. The scoring system is designed to reflect the severity of aphasia, with higher scores indicating milder impairment and lower scores reflecting more significant language deficits. The WAB Bedside provides a detailed scoring guide that outlines the criteria for assigning points to each task.
