Sadly, aphasia can mask a persons intelligence and ability to communicate feelings, thoughts and emotions. (The Aphasia Institute, Canada)), 3 months, and at least 6 months post-baseline. There was a significant main effect for time (F=43.33, df=2.96, p<0.0001), and post-hoc analysis by Newman-Keuls shortest significant range test revealed significant differences in the mean scores for the three tests (p<0.01). (AUC=1.000). 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). 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. Kertesz, A. Aftonomos, L.B., Steele, R.D., Appelbaum, J.S., & Harris, V.M. coefficient and reported 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.

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. Relationships between impairment-level assessments and functional-level assessments in aphasia: Findings from LCC treatment programmes. The supplemental section is used to distinguish whether a client has semantic and phonological dyslexia. 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. 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. of composite scores and all subtests was excellent (AphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate.

No specific training is required to administer the WAB. was excellent for the WAB-AQ (r=0.986-0.997), WAB-CQ (r=0.992-0.998), all WAB-LQ subtests (also reported in Shewan, 1986): Spontaneous Speech Information Content (r=0.926-944), Spontaneous Speech Fluency (r=0.794-0.989), Comprehension (r=0.985-0.993), Repetition (r=0.993-0.997), Naming (r=0.995-0.999), Reading/Writing (r=0.985-0.998), and the Praxis (r=0.983-0.989) and Construction (0.948-0.996) subtests. (The Aphasia Institute, Canada) secondary to acute strokeAlso called a brain attack and happens when brain cells die because of inadequate blood flow. Participants were assessed on two occasions anywhere from 6 months to 6.5 years apart (average 12-23 months between testing). Scores on each of the WAB-R subtests were obtained to derive AQ, WAB-R aphasia profile, and 3 ratios reflecting relative performance on subtests. 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. Bakheit, Carrington, Griffiths and Searle (2005) 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. Higher values represent higher levels of internal consistency. It is generally understood to be the extent to which a measure is stable or consistent and produces similar results when administered repeatedly. of WAB Spontaneous Speech, Auditory Comprehension, Repetition, Naming, Reading and Writing subtests (reported by Shewan (1986) as the WAB-LQ) with 140 patients with aphasiaAphasia is an acquired disorder caused by an injury to the brain and affects a persons ability to communicate. 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).
