Abstract

Objective and accurate cognitive assessment scales are essential for guiding cognitive rehabilitation following stroke. The aim of this study was to evaluate the validity and reliability of the Mandarin Chinese version of the Brief Assessment of Impaired Cognition (BASIC) in stroke patients. The English version of the BASIC scale was translated into Mandarin Chinese, and 56 stroke patients at a stroke treatment center were enrolled in the study. The Mini-Mental State Examination (MMSE) and BASIC scale were used to evaluate the patients’ cognitive function, and content validity, structural validity, concurrent validity, internal consistency, interrater consistency and reliability and test-retest reliability were used to evaluate the test results. The correlation coefficients between each item of the BASIC scale and the total score were between 0.416 and 0.804 (p < 0.05). The total score on the BASIC scale was correlated with the total score on the MMSE (r = 0.479, p < 0.05). Four factors were extracted by exploratory factor analysis, and the cumulative variance contribution rate was 74.932%. The factor loading of each item on the corresponding factor was > 0.5, indicating that the scale has good structural validity. Internal consistency was good (Cronbach’s α = 0.821), as were interrater (ICC > 0.95) and test-retest reliability (ICC = 0.815–0.941). Therefore, the Chinese version of the BASIC scale has good reliability and validity and can assist in screening for cognitive dysfunction or dementia in stroke patients.

摘要

客观准确的认知评估量表对于指导脑卒中后的认知康复至关重要。本研究的目的是评估中文普通话版认知障碍简要评估 (BASIC) 在中风患者中的有效性和可靠性。将英文版的 BASIC 量表翻译成普通话，中风治疗中心的 56 名中风患者参加了这项研究。采用简易精神状态量表（MMSE）和BASIC量表评价患者的认知功能，采用内容效度、结构效度、同时效度、内部一致性、评分者间一致性和信度、重测信度对测验进行评价结果。BASIC量表各题项与总分的相关系数均在0.p  < 0.05）。BASIC 量表的总分与 MMSE 的总分相关（r  = 0.479，p  < 0.05）。探索性因子分析提取4个因子，累计方差贡献率为74.932%。各题项对相应因子的因子载荷>0.5，说明该量表具有良好的结构效度。内部一致性很好 (Cronbach's α  = 0.821)，评分者间 (ICC > 0.95) 和重测信度 (ICC = 0.815–0.941) 也很好。因此，中文版BASIC量表具有良好的信度和效度，可辅助脑卒中患者认知功能障碍或痴呆的筛查。
