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. Purpose The primary aim was to examine the utility of the Western Aphasia BatteryRevised (WAB-R; Kertesz, 2007) for classifying variants of primary progressive aphasia (PPA). For some attributes, no gold standard exists. There was an adequate correlationThe extent to which two or more variables are associated with one another.

WebDescription Western Aphasia BatteryRevised (WABR; Kertesz, 2007), Aphasia Quotient, is a composite score that provides an overall measure of severity, in which lower scores denote more severe aphasia(a score > 93.8 is considered to be within normal limits). 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 Western Aphasia Battery (WAB) was also administered to these patients to assess concurrent validity. One study examined construct validityReflects the ability of an instrument to measure an abstract concept, or construct. WAB-LQ scores changed in a similar fashion for the three severity levels across time. several months apart, using Pearson product moment correlationThe most commonly used method of computing a correlation coefficient between variables that are linearly related. They are then asked to point to the object that matches the word on the card shown to them. of the WAB. 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.
