Research on Alzheimer's disease (AD) is gaining more and more attention, and its treatment is currently mainly early intervention or delaying progression
.
Mild cognitive impairment (MCI) has been generally accepted as a transitional stage before AD, but in recent years, some scholars have proposed the concept of subjective cognitive impairment (SCCs), believing that SCC refers to a state
in which the main complaint or admission of cognitive impairment but a series of cognitive tests perform normally.
Subjective cognitive impairment (SCCs) are thought to be the earliest signs
of dementia in older adults.
However, it is unclear whether SCC is equivalent
in different cultures.
The Cognitive Function Tool (CFI) is an SCC measurement tool
that includes 14 items.
This pilot study aimed to explore the psychometric properties of the Cognitive Function Tool (CFI) as an SCC and its performance
in differentiating mild cognitive impairment (MCI) from normal control (NC) compared to objective cognitive screening (Montreal Cognitive Assessment [MoCA]).
Study methods: To include 194 community-dwelling non-dementia older adults with racial/ethnic diversity
.
Factor analysis, Cronbach's alpha, and McDonald's omega were used to test the unidimensionality and internal consistency
of CFI.
Logistic regression models and receiver operating characteristics (ROC) analysis are used to check CFI performance
.
The results showed that the CFI showed sufficient internal consistency; However, the fit to a single-dimensional model is not ideal
.
CFI distinguishes MCI from NC, or in combination with
MoCA.
ROC analysis shows comparable
performance between CFI and MoCA.
Taken together, the results support CFI as a simple and easy screening tool to detect MCI
in older adults from cultural/linguistic backgrounds.
