Development and validity of the Computer‐Based Cognitive Assessment Tool for intervention in community‐dwelling older individuals

Abstract

Aim The Mini‐Mental State Examination is a widely used cognitive assessment tool. However, it has several limitations, including the learning effect and interrater reliability. Therefore, we developed a Computer‐Based Cognitive Assessment Tool (CompBased‐CAT), which runs on a tablet or personal computer. In this study, we examined the validity and discrimination ability of the CompBased‐CAT. Methods Participants were recruited from the Otasha‐Kenshin study carried out in 2016. We included 773 community‐dwelling older individuals in Japan (332 men, 441 women, aged 65–97 years). CompBased‐CAT scores were converted to z‐scores, and the correlation with Mini‐Mental State Examination scores was examined using Pearson's correlation coefficient. Furthermore, the ability to discern cognitive impairment was examined using the receiver operating characteristic curve. Results The Pearson's correlation coefficient for the Mini‐Mental State Examination scores and each task component of the CompBased‐CAT ranged from 0.24 to 0.41 (P < 0.001), and the correlation coefficient of the total z‐scores was 0.51 (P < 0.001). The sensitivity, specificity and area under the receiver operating characteristic curve of the discriminating ability of the CompBased‐CATool for cognitive impairment were 0.81, 0.77 and 0.85, respectively. Conclusions The CompBased‐CAT certainly possesses validity, discriminating ability and utility as a new cognitive assessment tool in community‐dwelling older individuals.

Digital Cognitive Biomarker for Mild Cognitive Impairments and Dementia: A Systematic Review

“…Again, test batteries showed group differences that varied largely ( g : 0.2–2.1). Test batteries including BHA [ 44 ], Computerized Dementia Screening Test (CDST) [ 59 ], Computerized Cognitive Screen (CoCoSc) [ 60 ], ComBased-CAT [ 61 ], and Boston Cognitive Assessment (BoCA) [ 62 ] showed large group differences, especially for subsets measuring memory, attention, and working memory. Moreover, performance in daily living tasks (i.e., Computer-based functional skills assessment and training (CFSAT)) showed moderate to large group differences ( g : 0.7–1.2) [ 63 ].…”

“…Around 90% of the studies included in our review were identified as having high quality based on NOS rating. However, eight studies did not match or control for both age and educational level, including one study using the Digital Trail-Making Test-Black and White (dTMT-B&W) [ 47 ], Self-Administered Tasks Uncovering Risk of Neurodegeneration (SATURN) [ 76 ], BrainCheck [ 83 ], Computerized Screening Test System [ 77 ], Computer-Based Cognitive Assessment Tool (CompBased-CAT) [ 61 ], Cambridge Cognitive Examination administered by Computerized Adaptive Testing (CAMCOG-CAT) [ 78 ], one study using digital clock drawing test [ 57 ], and a serious game named Episodix [ 39 ]. Given that dementia is an age-related disease, and education level was suggested to be associated with as the risk for dementia a higher level of education level may protect people against dementia by increasing “intellectual reserve” [ 84 , 85 ].…”

A Study of the Effectiveness Verification of Computer-Based Dementia Assessment Contents (Co-Wis): Non-Randomized Study

“…First, Co-Wis still requires a standardization score and big data collection in various environments. Secondly, to develop a computerized neurocognitive test that is effective in predicting and detecting dementia and multi-national data, the development of an English version and the verification of its validity and reliability are issues that need to be approached in the future [39]. Thirdly, in the future, it would be necessary to further verify the role of Co-Wis in dementia prevention and diagnosis by comparing patients with healthy controls (RCT).…”

Update and review of the gerodontology prospective for 2020's: Linking the interactions of oral (hypo)-functions to health vs. systemic diseases

“…In general, the elderly with dementia likely practice good oral hygiene insufficiently with greater difficulties for health, thereby suffering higher rates of caries, periodontal disease and other oral illnesses. 99 , 100 , 101 , 102 , 103 , 104 In addition, they develop further problems from the dietary intake, chewing & swallowing issues, and dysphagia as well. 74 , 85 , 105 Further to these, Japanese Society of Gerodontorogy (JSG) has worked proactively to launching research in order for revealing the links between dementia and oral care in the elderly.…”

“…The final GL is consisted of essential 38 CQs gathered via recruitments of public comments prior to its publication for documentation. 104 , 105 , 106 , 107 , 108 Nevertheless, new information and knowledge produced from CQs of the GL has enabled the development of Dentists' Response to the Training for Dementia Improvement in patients, as advocated in NOP. Further implementation for training at the workplaces regarding oral & nutritional care and managements has become possible later as to promotion and corporation with dental care and appropriate orally nutritional support for the elderly with dementia.…”
