DEVELOPMENT AND VALIDATION OF AN INTERACTIVE GAME-BASED DIGITAL COGNITIVE ASSESSMENT TOOL - Abstract citation ID igaf122.4098

Q: What is the IGD-CAT tool designed to do?

IGD-CAT is designed to screen mild cognitive impairment (MCI) in China by delivering a digital cognitive assessment using gaming scenarios and Chinese cultural elements.

Q: How was IGD-CAT evaluated for validity?

Concurrent validity was examined by correlating IGD-CAT with Montreal Cognitive Assessment (MoCA) scores, and discriminative validity was assessed using a random forest model.

Q: What cognitive domains does IGD-CAT cover?

IGD-CAT includes 14 tasks across seven domains: time orientation, attention, memory, language, calculation, visuospatial ability, and executive function.

Early screening and intervention are essential for mitigating cognitive decline, particularly by enabling timely prevention of Alzheimer’s disease (AD) through detection of mild cognitive impairment (MCI). This study addresses adoption barriers by developing IGD-CAT, a digital cognitive assessment tool that combines gaming scenarios with Chinese cultural elements for MCI screening in China. Its framework used literature review, expert panel input, and a Delphi survey, followed by evaluation of concurrent and discriminative validity.

Innovation in Aging, 2025, Vol. 9, No. S2 1225 Abstract citation ID: igaf122.4098 DEVELOPMENT AND VALIDATION OF AN INTERACTIVE GAME-BASED DIGITAL COGNITIVE ASSESSMENT TOOL Ruike Sun, Huixian Li, and Yanyan Wang, West China Hospital, Sichuan University, Chengdu, Sichuan, China (People’s Republic) Early screening and intervention are essential for mitigating cognitive decline, particularly for the prevention of Alzheimer’s disease (AD) through timely detection of mild cognitive impairment (MCI) . Despite advances in digital assessments, barriers still limit their adoption among older Chinese adults. This study developed a digital cognitive assessment tool integrating gaming scenarios and Chinese cultural elements for screening MCI in China (IGD-CAT) and evaluated its concurrent and discriminative validity. A theoretical framework was established through literature review, expert panel, and Delphi survey, and IGD-CAT was created via interdisciplinary collaboration. A total of 218 participants from communities and hospitals completed traditional assessments followed by IGD-CAT and were classified as normal cognition (NC) or MCI. Concurrent validity was examined through correlations with Montreal Cognitive Assessment (MoCA) scores, and discriminatory validity was assessed using a random forest model. IGD-CAT comprises 14 tasks across seven domains: time orientation, attention, memory, language, calculation, visuospatial ability, and executive function. Among 196 participants (mean age 63.6 ± 5.81 years), 93 were classified as MCI and 103 as NC. Task scores correlated positively with MoCA (r = 0.140–0.387), while completion times correlated negatively (r=-0.476 to-0.168). The total IGD-CAT score correlated with MoCA (r = 0.529, P<.001), whereas total completion time correlated negatively (r=-0.549, P<.001) . In the test set, the 1226 Innovation in Aging, 2025, Vol. 9, No. S2 random forest model achieved 89.65% sensitivity, 96.55% specificity, and an AUC of 0.96. IGD-CAT covers multiple cognitive domains, is time-efficient, and age-friendly. With high sensitivity and specificity, it is suitable for application in primary care, community, hospital, and home settings.
