A literature search was conducted to identify all relevant publications on the psychometric properties of the WAB relevant to individuals with strokeAlso called a brain attack and happens when brain cells die because of inadequate blood flow. It was designed as an assessment tool to examine linguistic skills (information content, fluency, auditory comprehension, repetition, naming and word finding, reading, and writing) and main nonlinguistic skills (drawing, block design, calculation, and praxis) of adults with aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. WebP-WAB-1 is a clinical linguistic measuring tool to determine severity and type of aphasia in brain damaged patients based on Aphasia Quotient (AQ) as a functional measure. As defined by the International Classification of Functioning, Disability and Health, activity is the performance of a task or action by an individual. Since the non-language portion is included in this summary score, it is not a sound indicator of language ability and its severity in aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. If the phenomenon being measured fluctuates substantially over time, then the test-retest paradigm may significantly underestimate reliability. (The Aphasia Institute, Canada) Battery (WAB) is a diagnostic tool used to assess the linguistic skills and main nonlinguistic skills of adults with aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. 80% of cases are also know as a schemic stroke, or the formation of a blood clot in a vessel supplying blood to the brain., using Wilcoxons rank sum test (W). One point is given for each animal names, even if it is distorted by literal paraphasia. The WAB-R includes a Bedside Screener that takes about 15 minutes to administer. (The Aphasia Institute, Canada) (n=24). There are a wide variety of methods for measuring correlation including: intraclass correlation coefficients (ICC), the Pearson product-moment correlation coefficient, and the Spearman rank-order correlation. The examiner may also gather information about spelling dyslexia, Patients between the ages of 18 and 89 with acquired neurological disorders due to, Alzheimers disease (Risser & Spreen, 1984), Nonaphasic right hemisphere lesions (Risser & Spreen, 1984). The client must point to what the examiner says. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. If the client fails to perform the command well, the examiner imitates the action; 2 points are given for a good performance at this point; 1 point is given for an approximate performance at this point. Sadly, aphasia can mask a persons intelligence and ability to communicate feelings, thoughts and emotions. The Fluency and Comprehension subtests were the principal components for Root 2, which accounted for 9% of total variance. of the WAB with a sample of 18 healthy adults and 18 patients with aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. It is most often the result of stroke or head injury. Scale; and adequate correlations with the Functional Independence Measure and Barthel Index. In using test-retest reliability, the investigator needs to take into account the possibility of practice effects, which can artificially inflate the estimate of reliability (National Multiple Sclerosis Society). The LQ score can range from 0-100. The supplemental section is used to distinguish whether a client has semantic and phonological dyslexia. Test-retest reliabilityA way of estimating the reliability of a scale in which individuals are administered the same scale on two different occasions and then the two scores are assessed for consistency. It is most often the result of stroke or head injury.An individual with aphasia may experience difficulty expressing themselves when speaking, difficulty understanding the speech of others, and difficulty reading and writing. (The Aphasia Institute, Canada) Quotient (r=0.76). In using test-retest reliability, the investigator needs to take into account the possibility of practice effects, which can artificially inflate the estimate of reliability (National Multiple Sclerosis Society).

It is most often the result of stroke or head injury.An individual with aphasia may experience difficulty expressing themselves when speaking, difficulty understanding the speech of others, and difficulty reading and writing. 80% of cases are also know as a schemic stroke, or the formation of a blood clot in a vessel supplying blood to the brain., using Pearson correlationThe extent to which two or more variables are associated with one another. In using test-retest reliability, the investigator needs to take into account the possibility of practice effects, which can artificially inflate the estimate of reliability (National Multiple Sclerosis Society). Maximum score for the alphabet is 12.5; for the numbers is 10. of the WAB by factor analysis with a sample of 142 patients with aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. They are then asked to point to the word that matches the picture that is presented to them one at a time. was excellent for the WAB-AQ (r=0.968), WAB-CQ (n=9, r=0.895), WAB-LQ subtests (also reported in Shewan, 1986): Spontaneous Speech Information Content (r=0.947) and Fluency (r=0.941), Comprehension (r=0.881), Repetition (r=0.970), Naming (r=0.923), Reading (n=32; r=0.927) and Writing (n=25; r=0.956) and the Construction subtest (n=14, r=974). Many measurement instruments are multidimensional and are designed to measure more than one construct or more than one domain of a single construct. (The Aphasia Institute, Canada) and individuals without aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. WP was measured as the proportion of productive words to total words for each minute of a language sample, and EF was measured as the total number of errors divided by the total number of productive words across a 10-minute speech sample. They are then asked to point to the object that matches the word on the card shown to them. 80% of cases are also know as a schemic stroke, or the formation of a blood clot in a vessel supplying blood to the brain., using Pearson correlationThe extent to which two or more variables are associated with one another. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel.
