(The Aphasia Institute, Canada), using Pearson correlationThe extent to which two or more variables are associated with one another. The WAB is also used to determine the location of the lesion. It is an individually administered assessment for adults with acquired neurological disorders (e.g., as a result of stroke, head injury, dementia). 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. In other words, convergent validity is used to evaluate the degree to which two or more measures that theoretically should be related to each other are, in fact, observed to be related to each other. There are 3 different pictures that must be matched. as a measure of severity. Three points are given if named correctly (or with a minor articulatory error); 2 points are given for a recognizable phonemic paraphasia; 1 point is given if the client needed a tactile or phonemic cue to respond correctly. (r=0.992). 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. True variation is that variation which actually reflects differences in the construct under study, e.g., the actual severity of neurological impairment. Since the same individual is completing both assessments, the raters subsequent ratings are contaminated by knowledge of earlier ratings. Predictive: of the K-WAB. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. Known groups: The examiner must remember to place all pictures and objects within the clients visual field. These significant increases in WAB-LQ scores with recovery support its validityThe degree to which an assessment measures what it is supposed to measure. Inter-rater: The language quotient (LQ): A new measure for the Western Aphasia Battery. The examiner can use the AQ score to classify the clients 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.An individual with aphasia may experience difficulty expressing themselves when speaking, difficulty understanding the speech of others, and difficulty reading and writing.

Half a point is given for every letter or number, despite the order. Reliability and validity characteristics of the Western Aphasia Battery (WAB). For patients 75 years and older with over 7 years of education an optimal cutoff of 72.7 produced 100% diagnostic accuracy. One study examined convergent validityA type of validity that is determined by hypothesizing and examining the overlap between two or more tests that presumably measure the same construct. The client must point to the piece of a pattern from that of a larger pattern. Sadly, aphasia can mask a persons intelligence and ability to communicate feelings, thoughts and emotions. This is a type of reliability assessment in which the same assessment is completed by the same rater on two or more occasions. Inter-rater: Convergent/Discriminant: Please see the test manual for further information. Six studies examined convergent validityA type of validity that is determined by hypothesizing and examining the overlap between two or more tests that presumably measure the same construct. (1982). Orange and purple points indicate the performance of two individuals not aphasic Shewan (1986) examined content validityRefers to the extent to which a measure represents all aspects of a given social concept.

Yiu, E.M.L. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. The client must spell the word said orally to them by the examiner. The WAB-R was normed on just twenty individuals: 6 neurologically healthy and 14 with aphasia (Kertesz, 2006, pg. Maximum score is 10. If the phenomenon being measured fluctuates substantially over time, then the test-retest paradigm may significantly underestimate reliability. Show 20 objects from various categories to client, and ask them to name them one at a time. This method of evaluating reliability is appropriate only if the phenomenon that the scale measures is known to be stable over the interval between assessments.

The examiner may repeat the instructions once, unless otherwise instructed in the manual. Computation: Like the LQ, each subtests score is a portion of the total score. Inter-rater reliability determines the extent to which two or more raters obtain the same result when using the same instrument to measure a concept. 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 also known as: nominal aphasia or amnesic (or amnestic) aphasia. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. A method of measuring reliability . There are 6 items in each category: real objects, drawn objects, forms, letters, numbers, colors, furniture, body parts, fingers and right-left body parts.
