The Memory Failures of Everyday (MFE) is a widely used instrument for assessing memory failure. The aim of the study was to analyze the MFE items using the Rasch model in a sample of cognitively older adults in Spain.
A cross-sectional validation study in a sample of 214 healthy people aged ≥60 years who used centers for older people in Madrid (Spain). The MFE for the assessment of memory complaints was used. The following properties of the Rasch model were assessed: data fit, reliability, unidimensionality, local dependence and lack of differential item functioning by gender, age and marital status.
The MFE showed a good fit to the Rasch model (χ (140) = 160.2; P = 0.116) and high reliability (person separation index = 0.808). The questionnaire was unidimensional (6.54% t-test; IC binomial = 0.036-0.095). The items showed lack of local dependence between them and differential item functioning. The MFE scores were transformed into linear interval scores with a median of 44.31 and an observed range of 17.9-89.2 (theoretical range: 0-100).
The MFE is a unidimensional, reliable instrument to assess memory complaints in cognitively healthy older adults in Spain, with usefulness in clinical research and practice. The construct validity of the MFE linear score could not be fully confirmed and this deserves further investigation. Geriatr Gerontol Int 2022; 22: 332-337.
日常生活记忆失误（MFE）是一种广泛用于评估记忆失误的工具。本研究的目的是在西班牙认知老年人样本中使用 Rasch 模型分析 MFE 项目。
在马德里（西班牙）的老年人中心使用 MFE 对 214 名≥60 岁的健康人进行横断面验证研究。评估了 Rasch 模型的以下特性：数据拟合、可靠性、单维性、局部依赖性和性别、年龄和婚姻状况的差异项目功能。
MFE 与 Rasch 模型拟合良好（χ(140)=160.2；P=0.116），可靠性高（人员分离指数=0.808）。问卷具有单维性（6.54% t 检验；二项式 IC=0.036-0.095）。项目之间缺乏局部依赖性和差异项目功能。将 MFE 评分转换为线性区间评分，中位数为 44.31，观察范围为 17.9-89.2（理论范围：0-100）。
MFE 是一种在西班牙认知健康老年人中评估记忆抱怨的具有单维性、可靠性的工具，在临床研究和实践中有一定的应用价值。MFE 线性评分的结构效度不能完全得到证实，这值得进一步研究。老年医学与老年病学国际 2022；22：332-337。
