Several brief screening tests of cognitive function were compared with a reliable and valid global rating of the presence and severity of senile dementia of the Alzheimer type, the Washington University Clinical Dementia Rating (CDR). The six-item Short Blessed Test, the Short Portable Mental Status Questionnaire, the 26-item Blessed Information-Memory-Concentration Test, the Blessed Dementia Scale, and the Blessed Dementia Scale-Cognitive were able to discern both the presence of dementia and its severity. The six-item Short Blessed Test is preferred as a screening test because of its brevity, administration to the subject only, inclusion of a learning task, reliability, and neuropathologic validity. Evidence is presented for the convergent validity of the Initial Subject Protocol, used to derive the Clinical Dementia Rating.
将几种认知功能的简短筛查测试与阿尔茨海默型老年痴呆症存在与否及严重程度的可靠且有效的整体评分——华盛顿大学临床痴呆评定量表（CDR）进行了比较。六项简短Blessed测试、简短便携式精神状态问卷、26项Blessed信息-记忆-注意力测试、Blessed痴呆量表以及Blessed痴呆量表-认知部分均能够辨别痴呆的存在及其严重程度。六项简短Blessed测试因其简短、仅对受试者进行测试、包含学习任务、可靠性以及神经病理学有效性而被优先用作筛查测试。文中给出了用于得出临床痴呆评定量表的初始受试者方案的收敛效度证据。
