Preliminary validation study of the Russian Birmingham Cognitive Screen

Area of Science:

• Neuroscience
• Psychology
• Speech and Language Therapy

Background:

• Acquired language impairment post-stroke affects many individuals.
• The Birmingham Cognitive Screen (BCoS) is a tool for assessing cognitive function in these patients.
• There is a need for validated cognitive screening tools for Russian-speaking populations.

Purpose of the Study:

• To develop a Russian version of the BCoS (Rus-BCoS).
• To culturally and linguistically adapt the BCoS for the Russian context.
• To establish preliminary psychometric properties of the Rus-BCoS.

Main Methods:

• Translation and cultural adaptation of the BCoS.
• Assessed reliability (internal consistency, test-retest, interrater) in stroke patients.
• Examined convergent validity, sensitivity, and specificity using other neuropsychological tests.

Main Results:

• The Rus-BCoS demonstrated satisfactory internal consistency, test-retest, and interrater reliability.
• Performance on most Rus-BCoS tasks correlated significantly with validated cognitive measures.
• Patients with aphasia generally scored above zero on most Rus-BCoS sections.

Conclusions:

• The Rus-BCoS shows promise as a cognitive screening tool for Russian-speaking individuals with post-stroke aphasia.
• Further validation and development of normative data are needed.
• The Rus-BCoS may help address the lack of quantitative neuropsychological tools in Russia.
