Abstract
INTRODUCTION: Mobile applications are increasingly used to assess neurocognitive function, yet their usability may vary depending on the delivery platform and the user's motor abilities.
PURPOSE: This study evaluated the perceived usability of three distinct neurocognitive applications among older adults with and without Parkinson's Disease (PD).
METHODS: Twenty-five participants (10 females, 15 males; aged 57–81 years) were divided into two groups: individuals without PD (n = 11; M = 70.36 ± 6.87 years) and individuals with PD (n = 14; M = 72.64 ± 4.55 years). Each participant completed three trials (baseline, week 2, week 4) using three different applications: Sway Cognition on a smartphone (App 1), ImPACT QT on a tablet (App 2), and Reflexion Edge on a large touchscreen monitor (App 3). After each session, participants rated the perceived level of difficulty (PLD) for each application and ranked their overall preference.
RESULTS: Two 3×3×2 repeated measures ANOVAs were conducted to analyze PLD and application preference across time and groups. A significant main effect was found for application type on PLD, F(1.501, 16) = 6.354, p = 0.01, ηp² = 0.28, power = 0.79, with no significant differences across trials or between groups. Post-hoc analyses indicated that the smartphone (App 1, p = 0.01) and tablet (App 2, p = 0.02) applications were rated as significantly easier to use than the touchscreen monitor (App 3) by non-PD participants. A significant main effect was also found for application preference, F(1.966, 16) = 14.884, p < 0.001, ηp² = 0.48, power = 0.99, with App 1 being the most preferred overall, followed by App 2, and App 3 being the least preferred. These preferences were consistent across both groups.
CONCLUSION: While all participants showed a clear preference for the smartphone and tablet-based applications over the touchscreen monitor, no group differences were found based on PD status. These findings suggest that, regardless of neurological condition, applications on smaller devices may offer greater perceived ease of use in neurocognitive testing. Future research could explore how specific design features and motor control demands influence usability perceptions.
