Abstract

Introduction: Valid assessments of quality of life (QoL) and cognition are important in caring for individuals with severe dementia; there is an urgent need for validated assessment tools for specific populations. This study aimed to develop and validate Chinese versions of the Quality of Life in Late-Stage Dementia (QUALID-C) scale and the Cognitive Test for Severe Dementia (CTSD-C) for Chinese older adults.

Methods: This was a cross-sectional validation study comprised of 93 Chinese older adults with severe dementia recruited from 6 residential homes. The content and cultural validity of the QUALID-C and CTSD-C were evaluated by a 7-member expert panel, and interrater reliability, test-retest reliability, internal consistency, concurrent validity, and factorial structure were examined.

Results: The QUALID-C showed acceptable internal consistency (Cronbach α = 0.65), good interrater reliability (intraclass correlation coefficient [ICC] = 0.99), and good test-retest reliability (ICC = 0.96). Principal component analysis yielded 3 factors; the items loaded on the factors were comparable to those in previous studies and suggested the scale's multidimensionality to measure QoL. The CTSD-C showed satisfactory internal consistency (Cronbach α = 0.862), good interrater reliability (ICC = 0.99), and good test-retest reliability (ICC = 0.958). Principal component analysis yielded 3 factors; the items loaded on factors 1 and 2 resembled the items of the automatic response and attentional control factors of the original study.

Conclusion: The QUALID-C and the CTSD-C are reliable and valid scales to measure the QoL and cognitive functions of Chinese older adults with severe dementia. These assessments can be utilized to evaluate the effectiveness of treatment and future research work.

晚期痴呆患者生活质量中文版及重度痴呆患者认知测试的发展。
有效的生活质量(QoL)和认知评估对于照顾重度痴呆患者非常重要;迫切需要针对特定人群的有效评估工具。本研究旨在开发和验证中国老年人晚期痴呆生活质量量表(Quality - c)和重度痴呆认知测试(CTSD-C)的中文版。方法:这是一项横断面验证研究,包括来自6个住宅的93名中国重度痴呆老年人。QUALID-C和CTSD-C的内容和文化效度由7人专家小组评估,并检验了判读信度、重测信度、内部一致性、并发效度和析因结构。结果:quality - c具有良好的内部一致性(Cronbach α = 0.65),良好的组间信度(类内相关系数[ICC] = 0.99),良好的重测信度(ICC = 0.96)。主成分分析得到3个因子;这些因素所载的条目与以往的研究结果相当,表明该量表测量生活质量的多维性。CTSD-C具有良好的内部一致性(Cronbach α = 0.862)、良好的测间信度(ICC = 0.99)和良好的重测信度(ICC = 0.958)。主成分分析得到3个因子;加载因子1和因子2的项目与原研究的自动反应和注意控制因素的项目相似。结论:quality - c和CTSD-C量表是衡量我国老年重度痴呆患者生活质量和认知功能的可靠有效量表。这些评估可以用来评估治疗的有效性和未来的研究工作。
