Tablet-based assessment protocol for cognition: development and preliminary usability testing of a cognitive screening tool.
Article in Frontiers in psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: Computerized cognitive screening offers several advantages over traditional paper-and-pencil methods, including standardized administration, automated scoring, and scalable deployment. Touchscreen-based tools provide an intuitive and accessible interface for digital screening in both clinical and non-clinical contexts. However, there is continued interest in developing brief digital home-deliverable screening tools that encompass multiple cognitive domains and in systematically addressing usability during tool development. Methods: This paper presents the development and preliminary usability evaluation of TAP-COG, a tablet-based cognitive screening tool assessing processing speed, sustained attention, inhibitory control, short-term memory, and resistance to interference. TAP-COG comprises five self-administered tasks-Visual Reaction Time, Go/No-Go, Visual Recognition, Simon, and Interference-optimized for tablet interaction, requiring approximately 30 min to complete. Key performance metrics (reaction time, accuracy, errors) are automatically recorded. We conducted a usability study with 80 healthy adults (mean ± SD age: 40.75 ± 17.72; Montreal Cognitive Assessment: 28.45 ± 1.72) using the System Usability Scale. Results: All participants completed the battery independently and reported clear instructions and ease of use. Overall, 80% rated usability as "good" to "excellent," with no significant influence of age, education levels, or cognitive status on usability ratings. Conclusion: TAP-COG demonstrates high usability, supporting its potential as a scalable, self-administered cognitive screening tool. These findings justify further validation in larger and more diverse populations and highlight TAP-COG's promise for both research and clinical applications.
