Abstract
To develop a novel cognitive screening tool for older adults in China. "Game-based Cognitive Assessment-3 Minute Version"(G3) was designed and developed based on WeChat mini-program. And its feasibility was analyzed. G3 mini-program contains three one-minute mini digital games and supports users' self-assessment of cognitive functions with instant access to reports. G3 had a good correlation with Montreal Cognitive Assessment Basic (MoCA-B) with Pearson's r =0.611 (P<0.001). Among natural users aged 50 and older (71 179), the G3 initiation and completion rates were 99.55% and 92.28%, respectively. The average time to complete G3 assessments was (278.5±73.73) seconds. The novel G3 mini-program has good feasibility and usability for older Chinese adults, and can be used for cognitive screening and home self-assessment.
