Objective A computer-based test for the assessment of working and short-term memory and selective attention was evaluated in Alzheimer patients and controls.Methods By means of the MAT, working and short-term memory for verbal, figural and episodic material are assessed through recognition tasks. Selective attention is tested through visual samples in an oddball paradigm. In 42 Alzheimer patients and 42 controls, we applied the MAT and usual reference methods for the assessment of attention and the respective memory domains.Results The correlations of the scores of the MAT memory subtests with the scores of the reference tests were moderate to high (r: 0.63-0.84). Test-retest correlations were between 0.79 and 0.90. Differentiation of Alzheimer patients and controls was good, particularly in episodic and figural short-term memory (p < 0,01). Nearly all of the probands reported that they could see and hear everything well and felt at ease during the MAT assessment.Conclusions High correlations of the MAT subtests with the reference tests indicate an acceptable construct validity. The test-retest correlations show a good reliabilty. Differentiation of Alzheimer patients and controls is fairly well. The computer-based assessment was readily accepted by the elderly probands.
对一种用于评估阿尔茨海默病患者和对照组工作记忆、短期记忆及选择性注意力的计算机化测试进行评估。
借助MAT，通过识别任务评估言语、图形和情景材料的工作记忆和短期记忆。通过在奇异球范式中呈现视觉样本测试选择性注意力。对42名阿尔茨海默病患者和42名对照者应用MAT以及评估注意力和各个记忆领域的常用参考方法。
MAT记忆子测试得分与参考测试得分的相关性为中度至高度（r：0.63 - 0.84）。重测相关性在0.79至0.90之间。阿尔茨海默病患者与对照者之间的区分良好，尤其是在情景和图形短期记忆方面（p < 0.01）。几乎所有受试者均表示在MAT评估期间他们能清楚看到和听到所有内容且感觉轻松。
MAT子测试与参考测试的高相关性表明其具有可接受的结构效度。重测相关性显示出良好的可靠性。阿尔茨海默病患者与对照者之间的区分相当好。基于计算机的评估很容易被老年受试者接受。
