Development of a Validated Chinese Short Version of the Montreal Cognitive Assessment (Moca) for Detecting Cognitive Impairment

Introduction:

Cognitive impairment is a common condition that affects millions of people worldwide, particularly in older adults. Accurate and efficient screening methods are essential to diagnose and manage cognitive impairment effectively. The Montreal Cognitive Assessment (MoCA) is a widely used tool for assessing cognitive function, but it has limitations due to its lengthy duration and complexity. Therefore, there is a strong need for short and effective methods to screen for cognitive impairment.

Background:

Recent studies have created short forms of the MoCA in English-speaking populations, demonstrating the feasibility of adapting this assessment tool for diverse cultural settings. However, a validated Chinese short version of the MoCA remains lacking. This omission hinders the accurate detection and management of cognitive impairment among Chinese-speaking individuals.

Objective:

To develop a validated Chinese short version of the MoCA (s-MoCA) to detect cognitive impairment in Chinese-speaking populations.

Methods:

We conducted a cross-sectional study involving 150 participants from Beijing, China. The s-MoCA was administered to each participant, and their cognitive function was assessed using the full-length MoCA as a reference standard. We used a backward elimination approach to select items with optimal sensitivity and specificity for detecting cognitive impairment.

Results:

The final Chinese short version of the MoCA consisted of 11 items that demonstrated high reliability (Cronbach's alpha = 0.87) and validity (sensitivity = 0.83, specificity = 0.90). Our results showed that this validated s-MoCA was effective in detecting cognitive impairment among Chinese-speaking individuals.

We developed a validated Chinese short version of the MoCA (s-MoCA) to detect cognitive impairment in Chinese-speaking populations. This concise and easy-to-administer tool fills an important gap in the assessment of cognitive function among Chinese-speaking individuals, enabling healthcare professionals to accurately diagnose and manage cognitive impairment more efficiently.
