Usability and feasibility of INFORMA platform for computerized cognitive stimulation in mild cognitive impairment and...

Mild cognitive impairment (MCI) and dementia represent significant global health challenges requiring innovative intervention approaches. Computerized cognitive training (CCT) offers promising alternatives to traditional face-to-face interventions, providing flexibility and personalized care for individuals with cognitive disorders.

This study evaluated the usability of INFORMA, a novel software platform based on Cognitive Activation Therapy (CAT), for delivering telerehabilitation to participants with MCI and mild-to-moderate dementia.

A prospective, non-interventional multicenter study enrolled 241 participants (MMSE 20-30, CDR 0.5-1) from 12 Italian Centers for Cognitive Disorders and Dementia. Participants engaged in an 8-week tablet-based telerehabilitation program with weekly supervision. Usability was assessed using the System Usability Scale (SUS), Task Completion Rate (TCR), and Relative Task Completion Time (R-TCT), supplemented by participant and caregiver questionnaires.

Of 219 completing participants (mean age 73.5 years), the mean SUS score was 82.0 (95% CI: 80.3-83.8), with 84% exceeding the usability threshold (SUS score > 68). Mean TCR reached 97.8%, while 70.3% demonstrated improved R-TCT. Higher SUS scores correlated with education and MMSE scores but decreased with age. Satisfaction ratings exceeded 87% for participants and 95% for caregivers.

INFORMA demonstrated high usability across all educational and cognitive levels, with the hybrid model combining automated exercises and professional supervision being well-received.

INFORMA showed significant promise as a user-friendly computerized cognitive stimulation tool, supporting its potential efficacy for MCI and dementia interventions and warranting further therapeutic efficacy studies.
