Reliability and Validity of the Brief Assessment of Impaired Cognition (Turkish Version) for Stroke Patients

Patients often experience cognitive problems after a stroke, which can significantly restrict their daily life activities. The aim of our study was to evaluate the validity and reliability of the Turkish version of the Brief Assessment of Impaired Cognition (BASIC) in stroke patients. This cross-sectional study included 64 stroke patients. Internal consistency was excellent (Cronbach's alpha = 0.909), as was test-retest reliability (ICC = 0.949). The correlation coefficients between the subcomponents of the scale and the total BASIC score ranged from 0.815 to 0.865 (<i>p</i> < 0.05). The total BASIC score was significantly correlated with the Mini-Mental State Examination total score (ρ = 0.749, <i>p</i> < 0.05). This study provides preliminary evidence that the Turkish version of BASIC may be a reliable and valid tool for assessing cognitive impairments in stroke patients. Further research with larger and more diverse samples is needed to confirm these findings.
