Abstract:
OBJECTIVE: To develop the Korean version of the Cognitive Assessment Scale for Stroke Patients (K-CASP) and to evaluate the test reliability and validity of the K-CASP in stroke patients. METHODS: The original CASP was translated into Korean, back-translated into English, then reviewed and compared with the original version. Thirty-three stroke patients were assessed independently by two examiners using the K-CASP twice, with a one-day interval, for a total of four test results. To evaluate the reliability of the K-CASP, intra-class correlation coefficients were used. Pearson correlations were calculated and simple regression analyses performed with the Korean version of Mini-Mental State Examination (K-MMSE) and the aphasia quotient (AQ) to assess the validity. RESULTS: The mean score was 24.42±9.47 (total score 36) for the K-CASP and 21.50±7.01 (total score 30) for the K-MMSE. The inter-rater correlation coefficients of the K-CASP were 0.992 on the first day and 0.995 on the second day. The intra-rater correlation coefficients of the K-CASP were 0.997 for examiner 1 and 0.996 for examiner 2. In the Pearson correlation analysis, the K-CASP score significantly correlated with the K-MMSE score (r=0.825, p<0.001). The coefficients of determination (r²) of the AQ were 0.586 for the K-MMSE and 0.513 for the K-CASP in the simple regression analysis. CONCLUSION: The K-CASP is a reliable and valid instrument for cognitive dysfunction screening in post-stroke patients. It is more applicable than other cognitive assessment tools in stroke patients with aphasia.
