本研究对功能性认知的一种新的基于操作的筛选方法--菜单任务（MT）的结构效度进行了评价。我们在研究中招募了114名社区居民成年人（55岁或以上）：所有参与者都完成了MT和其他四项神经心理学筛查措施。结构效度采用三步分层回归模型进行评估，MT作为因变量。在第1步输入人口统计学控制变量，然后在第2步进行精神状态简短访谈（BIMS）和连线测试A（TMT A），最后在第3步进行TMT B和蒙特利尔认知评估（莫卡）。有人假设，执行功能（TMT B和莫卡）敏感的措施将显着解释MT性能控制人口统计变量和认知功能的措施，模型后，提供额外的证据，结构效度的MT。模型的所有三个步骤都具有统计学显著性（p < 0.01）。在第3步中纳入对执行功能敏感的指标解释了MT评分30%的变异性（调整后的R-2 = 0.30）。我们的研究结果提供了进一步的实证支持的MT的结构效度，并提供了在急性和急性后护理环境中使用的MT的影响。
This study evaluated the construct validity of the Menu Task (MT): a new performance-based screening measure of functional cognition. We enrolled 114 community dwelling adults (55 years or older) in the study: all participants completed the MT and four other neuropsychological screening measures. Construct validity was evaluated using a three-step hierarchical regression model with the MT as the dependent variable. Demographic control variables were entered at step 1, followed by the Brief Interview of Mental Status (BIMS), and the Trail Making Test A (TMT A) at step 2, and finally TMT B and the Montreal Cognitive Assessment (MoCA) at step 3. It was hypothesised that measures sensitive to executive functioning (TMT B and MoCA) would significantly explain MT performance after controlling for demographic variables and adding measures of cognitive function to the model, providing additional evidence for construct validity of the MT. All three steps of the model were statistically significant (p < 0.01). Inclusion of measures sensitive to executive function in step 3 explained 30% of variability in MT score (adjusted R-2 = 0.30). Our findings provide further empirical support for the construct validity of the MT, and offer implications for the use of the MT in acute and post-acute care settings.
