Our aim was to analyze the psychometric properties of the Mini-Mental State Examination-37 using the Rasch Model (RM) in order to identify the cognitive domains that optimize detection of dementia in the Spanish population. All participants (n = 3955) were part of the NEDICES (Neurological Disorders in Central Spain) cohort study designed to detect dementia in persons aged 65 years and older. Clinical diagnosis of dementia (n = 178) was established by consensus of expert neurologists according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria. Results indicate that the items on the MMSE-37 have a good fit with the assumptions of the RM. None of the items on the MMSE-37 exhibits differential item functioning in relation to the groups. The items that assess orientation, attention, and language (repetition and comprehension) are those that best enable us to discriminate between the group with dementia and the group without dementia. The implications of the education and other sociodemographic characteristics of the population are discussed.
我们的目的是使用 Rasch 模型（RM）分析 Mini-Mental State Examination-37 的心理计量学特性，以确定在西班牙人群中优化痴呆检测的认知领域。所有参与者（n=3955）均为 NEDICES（西班牙中部神经疾病）队列研究的一部分，该研究旨在检测 65 岁及以上人群的痴呆症。根据《精神障碍诊断与统计手册》（DSM-IV）标准，由专家神经病学家组成的共识小组确定痴呆症的临床诊断（n=178）。结果表明，MMSE-37 的项目与 RM 的假设具有良好的拟合度。MMSE-37 上没有任何项目在与群体相关的方面表现出差异的项目功能。评估定向、注意力和语言（重复和理解）的项目是能够最好地区分痴呆组和非痴呆组的项目。还讨论了人口的教育和其他社会人口特征的影响。
