“…Fortunately, new technologies may provide a solution by translating performance-based tasks to increasingly scalable platforms. Using a nonimmersive tablet-based virtual reality task modeled after the Naturalistic Action Task (Schwartz, Segal, Veramonti, Ferraro & Buxbaum, 2002), Giovannetti et al (2018) have shown that the Virtual Kitchen task can quantify subtle and discrete types of micro-errors that occur during the completion of an everyday task, and that performance on this task is associated with underlying cognition. Other novel measures that leverage computer-and phone-based platforms include the Harvard Automated Phone Task Marshall et al.…”

Objective:Relative to dementia, little is known about informant bias in mild cognitive impairment (MCI). We investigated the influence of informant demographic and relational characteristics on reports of everyday functioning using the Functional Activities Questionnaire (FAQ).Method:Four thousand two hundred eighty-four MCI participants and their informants from the National Alzheimer’s Coordinating Center Uniform Data Set were included. Informants were stratified according to cohabitation, relationship, visit frequency, race/ethnicity, education, and sex. Informant-rated Mean FAQ score was compared across these groups using univariate general linear model analyses and post hoc tests. Interactions were tested between informant variables. The predictive contribution of informant variables to FAQ score was explored using hierarchical linear regression. Analyses covaried for participant cognition using a cognitive composite score, and for participant age, sex, and depression.Results:After controlling for participant cognition, depression, age, and sex, informant-rated FAQ scores varied significantly across all informant variables (p’s < .005, ηp2’s ≤ .033) except sex and visit frequency. FAQ scores were higher (more impaired) among informants who cohabitate with the participant, among paid caregivers, spouses, and adult children, and among informants with higher levels of education. Scores were lowest (less impaired) among Black/African American informants as compared to all other racial/ethnic groups.Conclusions:Demographic and relational characteristics of informants influence the perception and reporting of instrumental activities of daily living in adults with MCI. As everyday functioning is crucial for differential diagnosis and treatment outcome measurement, it is important to be aware of sources of informant report discrepancies.

“…The results also provide guidance on considerations for VR interfaces (sensors vs. controllers). Because of its strong potential to offer objective, sensitive and standardized assessment of everyday function in older adults and a wide range of clinical populations future research on VR assessments is needed to identify optimal interfaces and procedures, compare the utility against nonimmersive VR methods (Allain et al, 2014;Giovannetti et al, 2018), and ultimately establish the psychometric properties of immersive VR measures of everyday function. Moreover, the potential for immersive VR systems to offer interventions that might improve everyday functioning and promote independence should be explored (Banville et al, 2018;Foloppe et al, 2018).…”

“…Performance-based, functional tests are objective, standardized, allow a systematic comparison between individuals and provide detailed information on behaviors during the natural performance of activities. The validity of performance-based measures is supported by studies showing expected differences between clinical groups and controls (Giovannetti et al, 2002(Giovannetti et al, , 2008a(Giovannetti et al, , 2018Schwartz et al, 2002;Allain et al, 2014;Gold et al, 2015;Rycroft et al, 2018), significant (though modest) relations with cognitive tests (Giovannetti et al, 2002(Giovannetti et al, , 2008a(Giovannetti et al, , 2018Schwartz et al, 2002;Kessler et al, 2007;Allain et al, 2014;Rycroft et al, 2018), and informant and clinician reports of functioning (Giovannetti et al, 2002(Giovannetti et al, , 2008bSchwartz et al, 2002;Allain et al, 2014). Detailed analyses of errors and error-types afforded by performance-based tests of everyday function also have promoted theoretical frameworks to better characterize the breakdown of everyday function due to cognitive impairment (see Schwartz, 2006;Giovannetti et al, 2013; for a review).…”

“…In 2014, Allain et al (2014) reported results from the Virtual Kitchen (VK), a non-immersive activity that required participants to use a mouse to select and move target objects and avoid distractor objects on a computer screen to prepare a cup of coffee. In 2019 Giovannetti et al (2019) reported preliminary data from a modified VK, called the Virtual Kitchen Challenge (VKC), which included complex tasks to enable assessment of participants with mild cognitive difficulties and requires participants to use a touch screen interface instead of a mouse. Automated scores from the VKC were significantly associated with scores from the same tasks performed with real objects in a real kitchen.…”

Virtual Reality Cognitive Function Assessment feasible approach for function assessment even with older adults who might have very limited computer experience, no prior VR exposure, average educational experiences, and mild cognitive difficulties. Because of inherent limitations of single case reports (e.g., unknown generalizability, potential practice effects, etc.), group studies are needed to establish the full psychometric properties of the Virtual Reality Action Test.

“…Virtual reality (VR) is widely used in research with computerized cognitive testing for MCI [14,15]. VR is an ecologically valid and informative evaluation instrument and provides an opportunity to improve cognitive screening [16][17][18]. Studies have shown that VR is recommended for the screening of older adults with MCI or dementia [15,19].…”

Background Mild cognitive impairment (MCI) is often a precursor of dementia, and patients with MCI develop dementia at a higher rate than healthy older adults. Early detection of cognitive decline at the MCI stage supports better planning of care and interventions. 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. 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. Methods Subjects were recruited from several nursing homes and communities in Changchun, China. They were divided into a healthy control group (n=64) and an MCI group (n=62). All subjects were administered the VSP and a series of neuropsychological examinations. The study determined the optimal cutoff, discriminating validity, concurrent validity, and retest reliability of the VSP. We used the area under the receiver operating characteristic curve (AUC) to evaluate the discriminating validity and obtain the optimal cutoff values. Pearson correlation analysis and the intraclass correlation coefficient were used to evaluate the concurrent validity and retest reliability, respectively. 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). The median index of VSP score was 51.1 (range 42.6-60.0). There was a moderate positive correlation between the VSP total score and Mini-Mental State Examination score (r=0.429, P<.001). There was a strong positive correlation between VSP total score and Montreal Cognitive Assessment score (r=0.645, P<.001). The retest reliability of the VSP was feasible (r=0.588, P=.048). Conclusions The VSP is interesting and feasible for subjects. It shows high sensitivity and specificity for the identification of MCI in older adults, which makes it a promising screening method. The VSP may be generalized to older adults in other countries, although some cultural adaptation may be necessary.
