Short form of the Bilingual Aphasia Test in Russian: Psychometric data of persons with aphasia

摘要

There is currently a lack of standardised aphasia batteries available in the Russian language. The psychometric properties of a short form of the Russian version of the Bilingual Aphasia Test (BAT) (Paradis, 1987) were examined. The BAT (Paradis & Zeiber, 1987) is one of the few published tests in Russian.Aims: The primary aims were: (1) to describe the psychometric properties of a modified short form of the BAT in Russian by analysing the data collected on a large sample of Russian-speaking adults with aphasia; (2) to identify needs for further modification, validation, and standardisation; and (3) to provide a preliminary evidence base for clinicians and investigators using the test.Methods & Procedures: The modified short form of the Russian BAT was administered to 83 patients with mild to severe aphasia. All were native speakers of Russian. Outcomes & Results: The test was effective in discriminating patients according to level of severity of language impairment. Most of the tasks constituting the short form of the test had strong internal consistency. These results support the utility of each assessed component of the BAT in quantifying language deficits in speakers of Russian with aphasia. However, problems with the internal consistency and the validity of some items were identified.Conclusions: The study provides preliminary data on the psychometric properties of an aphasia test in Russian. Needs for modification of the test, suggestions for further development of the test, and recommendations for further study of its psychometric properties are discussed.
