Abstract:
Objective:To explore the clinical application value of the cognitive assessment scale for stroke patients(CASP)in post-stroke cognitive impairment(PSCI)based on the translation and reliability and validity testing of the original CASP in order to improve the cognitive assessment system for stroke patients.Method:The original version of CASP was translated into Chinese,and a total of 82 stroke patients were as-sessed using the Mini-Mental State Examination(MMSE),the Montreal Cognitive Assessment(MoCA)and the Chinese version of CASP(C-CASP).Reliability analysis was conducted using Cronbach's a coefficient and inter-group correlation coefficient(ICC).Structure validity and criterion validity were analyzed to assess the validi-ty.The stroke patients were stratified according to cognitive function,lesion location and injury nature using independent sample t-tests.Result:The reliability analysis showed the Cronbach's a coefficient was 0.792,and the inter-rater reliability ICC was 0.999 and 0.998,while the ICC was 0.985 and 0.982 for retest reliability.The structure validity anal-ysis extracted one factor with a cumulative contribution rate of 52.89％.The correlation coefficients of C-CASP with MMSE,MoCA and ADL were 0.867,0.848 and 0.597.The area under the curve(AUC)for C-CASP was 0.938,with an optimal cutoff score of 32,sensitivity of 94.5％,and specificity of 77.8％.The total scores and item scores of C-CASP in the patients with cognitive impairment were significantly lower than those in the patients with non-cognitive impairment(P＜0.05).The item scores of the"bisection of a horizontal line"in C-CASP were significantly lower in the patients with right hemisphere lesions compared to the patients with left hemisphere lesions(P＜0.05).Additionally,the patients with ischemic stroke scored significantly lower than the patients with hemorrhagic stroke on the items of"naming"and"comprehension"in C-CASP(P＜0.05).Conclusions:C-CASP is a reliable and valid screening tool for assessing cognitive function in stroke patients.C-CASP has a broader cognitive threshold,which is more suitable than MMSE for the assessment of cogni-tive function in stroke patients.
