The retest reliability of the VSP was feasible ( r=0.588, P=.048).Ĭonclusions: The VSP is interesting and feasible for subjects. There was a strong positive correlation between VSP total score and Montreal Cognitive Assessment score ( r=0.645, P<.001). There was a moderate positive correlation between the VSP total score and Mini-Mental State Examination score ( r=0.429, P<.001). The median index of VSP score was 51.1 (range 42.6-60.0). Results: A cutoff score of 46.4 was optimal for the entire sample, yielding a sensitivity of 85.9% and specificity of 79.0% for differentiating individuals with MCI and healthy controls, and the AUC was 0.870 (95% CI 0.799-0.924). Pearson correlation analysis and the intraclass correlation coefficient were used to evaluate the concurrent validity and retest reliability, respectively.
We used the area under the receiver operating characteristic curve (AUC) to evaluate the discriminating validity and obtain the optimal cutoff values.
The study determined the optimal cutoff, discriminating validity, concurrent validity, and retest reliability of the VSP. All subjects were administered the VSP and a series of neuropsychological examinations. They were divided into a healthy control group (n=64) and an MCI group (n=62). Methods: Subjects were recruited from several nursing homes and communities in Changchun, China.
Objective: The objectives of this study are to validate a VR game–based test, namely, the Virtual Supermarket Program (VSP), for differentiating patients with MCI and healthy controls and to identify cutoff scores for different age levels. At present, the use of virtual reality (VR) in screening for MCI in older adults is promising, but there is little evidence regarding the use of virtual supermarkets to screen for MCI. Early detection of cognitive decline at the MCI stage supports better planning of care and interventions.
