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.
