Introduction :
Introduction: Effective executive function (EF) is the key to achieve autonomy and independence in activities of daily living, and impairment in executive function is a major determinant of poor functional outcomes. Performance-based evaluation of EF is an important area of study for healthcare professionals. However, there is very little research regarding the relationship between executive function and actual functional ability in people with dementia. Performance-based evaluation by real-world daily living activities is an important area of research in people with dementia. neuropsychological test alone.
Objectives :
Objectives: To address this knowledge gap, this study is to develop a performance-based evaluation ˗ the Chinese Multiple Errands Test (Chinese-MET) for mild to moderate dementia.
Methodology :
Methods: This pilot study recruited fifty patients diagnosed with dementia and fifty age and demographic matched healthy controls. They were administered tests of performance-based executive function (Chinese MET), instrumental activities of daily living (Lawton IADL-CV), cognitive screening test (HK-MoCA) and functional disability (CDAD) of community residing individuals with dementia.
Result & Outcome :
Results: The Chinese MET demonstrated excellent interrater reliability, test-retest reliability and high internal consistency. Dementia subjects’ performance efficiency in the Chinese-MET showed significant correlation with the Lawton IADL-CV (r = 0.86, p< 0.001), the HK-MoCA (r = 0.86, p < 0.001), and the CDAD (r = 0.44, p < 0.001). Regression analysis of the relationship with sociodemographic factors indicated that the Chinese-MET was not significantly correlated with gender, education or age. Outcomes: The Chinese-MET was shown to be a reliable and valid instrument in assessing executive function in Chinese elderly subjects with dementia. The Chinese-MET can identify executive function deficits that would be missed by standard paper-and-pencil
