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 many variations on the measurement of reliability including alternate-forms, internal consistency , inter-rater agreement , intra-rater agreement , and test-retest . 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 criterion standard in this example would be whether the patient fell over the next 6 weeks. Three points are given for a good performance; 2 points are given for an approximate performance. Reliability and validity characteristics of the Western Aphasia Battery (WAB). WebWestern Aphasia Battery-Revised (WAB-R, Kertesz, 2006).

Accuracy of formal tests for diagnosing mild aphasia: An application of evidencebased medicine. Adaptable to various administration settings from hospital room to clinic, it provides a baseline level of performance to measure change over time. There were adequate to excellent correlations between the CETI and WAB Information (r=0.73), Fluency (r=0.73), Comprehension (r=0.65), Repetition (r=0.53) and Naming (r=0.75) subtests. The first two elements relate to spoken language performance and the latter two elements relate to written language performance. 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. 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. 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). Participants were assessed at baseline (2-4 weeks post-onset of aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. Laures-Gore, J.S., DuBay, M. F., Duff, M. C., & Buchanan, T. W. (2010). Internal consistency reflects the extent to which items of a test measure various aspects of the same characteristic and nothing else. Ross and Wertz (2004) examined sensitivitySensitivity refers to the probability that a diagnostic technique will detect a particular disease or condition when it does indeed exist in a patient (National Multiple Sclerosis Society). The patients with chronic post-stroke aphasia were tested 3 times each and scored independently by 2 raters to establish test-retest and inter-rater reliability. 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., who received treatment (n=42) or no treatment (n=8). of the K-WAB in a sample of 20 neurologically stable aphasic patients, using Pearsons correlationThe extent to which two or more variables are associated with one another. 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.

STROKE ENGINE was built with the goal of bridging the gap in knowledge translation between research findings and current clinical practice in stroke rehabilitation. 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. 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. If the phenomenon being measured fluctuates substantially over time, then the test-retest paradigm may significantly underestimate reliability. Aftonomos, Steele, Appelbaum and Harris (2001) used the WAB to measure change in communication at the impairment level following a community-based Language Care Center (LCC) Treatment Program with a sample of 50 patients with aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate.

(The Aphasia Institute, Canada) ScreeningTesting for disease in people without symptoms. Although a subscale could consist of a single item, in most cases subscales consist of multiple individual items that have been combined into a composite score (National Multiple Sclerosis Society). These different ratings are then compared, generally by means of correlation. (1992) Linguistic assessment of Chinese-speaking aphasics: Development of a Cantonese aphasia battery. The Western Aphasia Battery is a comprehensive test of language function for individuals with aphasia and aged 1889 years. 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 Pearsons correlationThe extent to which two or more variables are associated with one another. 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. Example: A depression scale may lack content validity if it only assesses the affective dimension of depression but fails to take into account the behavioral dimension. These different ratings are then compared, generally by means of correlation. 20% of cases are a hemorrhage in the brain caused by a rupture or leakage from a blood vessel. coefficients.
