To evaluate the validity of the Chinese version of the CogState battery, a computerised cognitive testing among patients with heart failure in Taiwan.
Cognitive deficits are common in patients with heart failure and a validated Chinese measurement is required for assessing cognitive change for this population. The CogState computerised battery is a measurement of cognitive function and has been validated in many languages, but not Chinese.
A cross-sectional study.
A convenience sample consisted of 76 women with heart failure and 64 healthy women in northern Taiwan. Women completed the Chinese version of the CogState battery and the Montreal Cognitive Assessment. Construct validity of the Chinese version of the battery was evaluated by exploratory factor analysis and known-group comparisons. Convergent validity of the CogState tasks was examined by Pearson correlation coefficients.
Principal components factor analysis with promax rotation showed two factors reflecting the speed and memory dimensions of the tests. Scores for CogState battery tasks showed significant differences between the heart failure and healthy control group. Examination of convergent validity of the CogState found a significant association with the Montreal Cognitive Assessment.
The Chinese CogState Battery has satisfactory construct and convergent validity to measure cognitive deficits in patients with heart failure in Taiwan.
The Chinese CogState battery is a valid instrument for detecting cognitive deficits that may be subtle in the early stages, and identifying changes that provide insights into patients' abilities to implement treatment accurately and consistently. Better interventions tailored to the needs of the cognitive impaired population can be developed.
评估中文版CogState测试组在台湾心力衰竭患者中进行计算机化认知测试的有效性。
认知缺陷在心力衰竭患者中很常见，评估该人群的认知变化需要一种经过验证的中文测量方法。CogState计算机化测试组是一种认知功能测量工具，已在多种语言中得到验证，但未在中文中得到验证。
一项横断面研究。
便利样本包括台湾北部76名心力衰竭女性和64名健康女性。女性完成了中文版CogState测试组和蒙特利尔认知评估。通过探索性因素分析和已知组比较来评估中文版测试组的结构效度。通过皮尔逊相关系数检验CogState任务的收敛效度。
采用斜交旋转的主成分因子分析显示有两个因子反映了测试的速度和记忆维度。心力衰竭组和健康对照组在CogState测试组任务得分上存在显著差异。对CogState收敛效度的检验发现其与蒙特利尔认知评估有显著关联。
中文版CogState测试组在测量台湾心力衰竭患者的认知缺陷方面具有令人满意的结构效度和收敛效度。
中文版CogState测试组是一种有效的工具，可用于检测早期可能不明显的认知缺陷，并识别能深入了解患者准确且持续实施治疗能力的变化。可以制定更适合认知障碍人群需求的干预措施。
