Validity and reliability of Mini-Mental State Examination in Older Adults in China: Inline Mini-Mental State Examination with cognitive functions

The main aim of the study is to validate factor structure Mini-Mental State Examination (MMSE) China’s older population using Chinese Longitudinal Healthy Longevity Survey. validation process used exploratory analysis (EFA) determine number dimensions MMSE, confirmatory (CFA) confirm factorial and invariance conclude does not differ between young-old (aged 65 – 79) old-old 80 or older). results EFAs suggested two possible structures: A six-factor a seven-factor solution. model turned out as best fit by comparison four competing models. Strict was attained for age groups, indicating high level measurement equality, property seldom achieved in literature studies. In MMSE that focused solely on EFA aims establish single summated score, present suggests EFA, CFA, takes into consideration errors preferred procedure since it establishes appropriate dimensionality line with their respective cognitive functions.
