Abstract

Introduction: The Memory Complaint Scale (MCS-15) is a 15-item instrument to explore frequent forgetfulness in daily life in people with possible cognitive impairment. However, knowledge about its psychometric performance is limited.

Objective: The objective of this study was to know the dimensionality and internal consistency of the MCS-15 in Colombian older adults.

Methods: A probabilistic sample of 1,957 older adults from the general Colombian population was taken, aged between 60 and 98 years (mean = 71.0 ± 7.9), and 62.2% were women. Internal consistency (Cronbach's alpha and McDonald's omega) and dimensionality (exploratory and confirmatory factor analysis) were calculated for the original and ten-item versions.

Results: The 15-item version showed Cronbach's alpha and McDonald's omega of 0.91, and one dimension accounted for 45.3% of the variance. A version of ten items showed Cronbach's alpha and McDonald's omega of 0.89 and a single factor that explained 50.9% of the variance with better indicators in the confirmatory factor analysis. Convergence with the shortened Mini-Mental State Examination was rs = 0.43 (p < 0.001), and the Montreal Cognitive Assessment test was rs = 0.38 (p < 0.001). The nomological validity with the geriatric depression scale was rs = 0.44 (p < 0.001), and women scored higher than men (p < 0.001).

Conclusions: The MCS-15 shows high internal consistency with poor dimensionality. However, a ten-item version shows high internal consistency and a clear one-dimensional structure. More research is needed: testing the performance against a structured interview for major cognitive impairment.

哥伦比亚60岁及以上老年人记忆抱怨量表的心理测量表现。

简介:记忆抱怨量表(MCS-15)是一个包含15个项目的工具，用于探索可能存在认知障碍的人在日常生活中的频繁遗忘。然而，对其心理测量性能的了解是有限的。目的:本研究的目的是了解哥伦比亚老年人MCS-15的维度和内部一致性。方法:从哥伦比亚普通人群中随机抽取1957例老年人，年龄在60 ~ 98岁之间(平均= 71.0±7.9)，其中62.2%为女性。内部一致性(Cronbach's alpha和McDonald's omega)和维度(探索性和验证性因子分析)对原始版本和十项版本进行了计算。结果:15项版本的Cronbach’s alpha和McDonald’s omega分别为0.91，其中一个维度占方差的45.3%。10个项目的版本显示Cronbach's alpha和McDonald's omega为0.89，单因素解释了50.9%的方差，在验证性因素分析中指标更好。缩短的迷你精神状态检查的收敛率rs = 0.43 (p < 0.001)，蒙特利尔认知评估测试的收敛率rs = 0.38 (p < 0.001)。老年抑郁量表的法效度为rs = 0.44 (p < 0.001)，女性得分高于男性(p < 0.001)。结论:MCS-15具有较高的内部一致性，但量纲性较差。而十项版本则表现出较高的内部一致性和清晰的一维结构。还需要更多的研究:通过结构化面试来测试主要认知障碍的表现。

期刊介绍： As a unique forum devoted exclusively to the study of cognitive dysfunction, ''Dementia and Geriatric Cognitive Disorders'' concentrates on Alzheimer’s and Parkinson’s disease, Huntington’s chorea and other neurodegenerative diseases. The journal draws from diverse related research disciplines such as psychogeriatrics, neuropsychology, clinical neurology, morphology, physiology, genetic molecular biology, pathology, biochemistry, immunology, pharmacology and pharmaceutics. Strong emphasis is placed on the publication of research findings from animal studies which are complemented by clinical and therapeutic experience to give an overall appreciation of the field.
