(The Aphasia Institute, Canada) secondary to chronic strokeAlso called a brain attack and happens when brain cells die because of inadequate blood flow. 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 r correlationThe extent to which two or more variables are associated with one another. of the WAB by comparison with a Danish adaptation and translation of the Communicative Effectiveness Index (CETI) in 66 patients with aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. Repetition and Information Content were principal components of Root 3, which accounted for 7% of total variance. Discriminative validity of selected measures for differentiating normal from aphasic performance. (The Aphasia Institute, Canada) secondary to chronic strokeAlso called a brain attack and happens when brain cells die because of inadequate blood flow. spiral-bound stimulus book replacing loose stimulus cards), as well as revised directions and scoring guidelines for clarity. There were excellent correlations between all tasks (r=0.606-0.726) except for an adequate correlationThe extent to which two or more variables are associated with one another. Inter-rater reliabilityA method of measuring reliability . 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. Discriminant validity examines the extent to which a measure correlates with measures of attributes that are different from the attribute the measure is intended to assess. There were excellent correlations between the K-BNT score and K-WAB Object Naming (r=0.720) and Word Fluency (r=0.613) tasks and Naming subtotal score (r=0.719). Kim and Na (2004) examined concurrent validityTo validate a new measure, the results of the measure are compared to the results of the gold standard obtained at approximately the same point in time (concurrently), so they both reflect the same construct. Since the same individual is completing both assessments, the raters subsequent ratings are contaminated by knowledge of earlier ratings. Example: can the Berg Balance Scale predict falls over the following 6 weeks? A correlation can be positive (as one variable increases, the other also increases for example height and weight typically represent a positive correlation) or negative (as one variable increases, the other decreases for example as the cost of gasoline goes higher, the number of miles driven decreases. 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. Sadly, aphasia can mask a persons intelligence and ability to communicate feelings, thoughts and emotions. Adaptable to various administration settings from hospital room to clinic, it provides a baseline level of performance to measure change over time. Three studies reported adequate to excellent 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. 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 Aphasia Institute, Canada) batteries and has similar items to the BDAE. (Client had concerns with ready and writing) Ive been trying to figure this out for a while but havent gotten a clear answer: how should I interpret the Language Quotient and Cortical Quotient? A correlation can be positive (as one variable increases, the other also increases for example height and weight typically represent a positive correlation) or negative (as one variable increases, the other decreases for example as the cost of gasoline goes higher, the number of miles driven decreases. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. 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. 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 Aphasia Institute, Canada) secondary to chronic strokeAlso called a brain attack and happens when brain cells die because of inadequate blood flow. Writing of dictated or visually presented words: The client must write down words that were dictated by the examiner. There were excellent correlations between the Naming subtest total score and all tasks (ON: r=0.971; WF: r=0.693; SC: r=0.785; RS: r=0.797). Sadly, aphasia can mask a persons intelligence and ability to communicate feelings, thoughts and emotions. No studies have reported on predictive validityA form of criterion validity that examines a measures ability to predict some subsequent event. 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. They are instructed to copy down this sentence. (The Aphasia Institute, Canada), using Newman-Keuls Shortest Significant Range Test.

The Western AphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. Known Groups: Sadly, aphasia can mask a persons intelligence and ability to communicate feelings, thoughts and emotions. (The Aphasia Institute, Canada). Kertesz and McCabe (1977) assessed 1-year 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. (The Aphasia Institute, Canada) Quotient with an Eye Movement Working MemoryExecutive process responsible for the temporary storage and manipulation of information in both simple (e.g. Aphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. (The Aphasia Institute, Canada) as 1 of 8 types (Kyoung Kang et al, 2010). In the absence of a gold standard , construct validation occurs, where theories about the attribute of interest are formed, and then the extent to which the measure under investigation provides results that are consistent with these theories are assessed. If the phenomenon being measured fluctuates substantially over time, then the test-retest paradigm may significantly underestimate reliability. Note: However, Risser and Spreen (1984) commented that WAB criteria for classification force assignments to types of 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. was excellent for the WAB-AQ, WAB-CQ, WAB-LQ subtests (also reported in Shewan, 1986) and the Praxis and Construction subtests. 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. The Japanese version of the Western Aphasia Battery. 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 Spearmans rho coefficients. These results suggest that all subtests of the K-WAB are stable and reliable over a short time period. If the client completes the task in 60 seconds, they are given 3 points. A correlation can be positive (as one variable increases, the other also increases for example height and weight typically represent a positive correlation) or negative (as one variable increases, the other decreases for example as the cost of gasoline goes higher, the number of miles driven decreases. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. Internal consistencyA method of measuring reliability . Ten points are given for the complete sentence being written down; 1 point is given for every correct word; 0.5 point is deducted for every spelling mistake or paraphasic error. Sadly, aphasia can mask a persons intelligence and ability to communicate feelings, thoughts and emotions. 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.. This approach is useful in situations when a new or untested tool is potentially more efficient, easier to administer, more practical, or safer than another more established method and is being proposed as an alternative instrument. 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. WebThe Western Aphasia BatteryRevised (WABR) is the updated version of the highly respected and widely used instrument for assessing adult patients with aphasia.

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. 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. This score is a weighted composite of performance on 10 separate WAB subtests. Pak-Hin Kong (2011) 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.

Shewan and Kertesz (1980) examined 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. between WAB AQ and EF (r=-0.54). Sadly, aphasia can mask a persons intelligence and ability to communicate feelings, thoughts and emotions. 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). 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. One study reported excellent inter-rater reliabilityA method of measuring reliability . These different ratings are then compared, generally by means of correlation.
