Moderating Effects of Demographic Variables on the Relationship Between Cognitive Functions and Instrumental Activities of Daily Living

Abstract
Cognitive functions and instrumental activities of daily living (ADL) are two crucial variables in distinguishing between mild cognitive impairment (MCI) and dementia. Inconsistent research findings have been reported in terms of the relationship between cognitive functions and instrumental ADL, which may be due to the different demographic characteristics of the subjects. The purpose of this study was to explore the moderating effect of demographic variables in the relationship between cognitive functions and instrumental ADL in patients with amnestic multi-domain MCI (amMCI, n=167) and dementia of the Alzheimer’s type (DAT, n=82). To evaluate the global cognitive ability, the Korean-Mini Mental State Examination (K-MMSE) and Seoul Neuropsychological Screening Battery 2nd Edition (SNSB-II) were administered to the patients as individual tests. The caregivers completed the Korean-Instrumental Activities of Daily Living (K-IADL) Scale. The K-MMSE and the five cognitive domain scores derived from SNSB-II such as attention, language, visuospatial function, memory, and frontal/executive function were used as predictor variables, the score of K-IADL as a criterion variable, and the demographic variables (age, sex, and years of education) as moderator variables. The moderating effect was verified by the hierarchical regression analysis. The results showed that age had a moderating effect on the relationship between K-MMSE, language, visuospatial function, memory, and frontal/executive function scores and instrumental ADL. Years of education had a moderating effect on the influence of K-MMSE on instrumental ADL, but no moderating effect was found in sex. The results imply that age and years of education in the MCI and DAT groups moderate the impact of cognitive functions on instrumental ADL, and age especially has a greater moderating effect.
