Validity and reliability of a digital solution for cognitive assessment: The Brain on Track®

Area of Science:

• Digital health solutions for cognitive assessment.
• Neuroscience and cognitive function monitoring.
• Gerontology and age-related cognitive changes.

Background:

• Remote digital solutions are increasingly used for cognitive assessment and early detection of cognitive impairments.
• The Brain on Track® is a digital tool employed in clinical settings for online cognitive screening and monitoring.

Purpose of the Study:

• To evaluate the validity and reliability of the Brain on Track® computerized cognitive test when administered on a tablet device.
• To assess the performance of the Brain on Track® tablet version in a diverse adult population.

Main Methods:

• A community sample of 155 adults (young, middle-aged, and older) participated in two assessment sessions.
• Data collected included sociodemographics, digital literacy, Brain on Track® on computer and tablet, and usability.
• Criterion validity and test-retest reliability were assessed using the Montreal Cognitive Assessment Questionnaire (MoCA) and repeated Brain on Track® tablet tests.

Main Results:

• A weak to moderate correlation was observed between Brain on Track® tablet scores and MoCA scores.
• Intraclass correlation coefficients (ICC) for test-retest reliability ranged from 0.72 to 0.84.
• Cronbach's alpha values indicated good internal consistency, ranging from 0.83 to 0.89 across age groups.

Conclusions:

• The Brain on Track® on a tablet device demonstrates criterion validity, especially in middle-aged and older adults.
• The digital cognitive assessment tool exhibits strong internal consistency and test-retest reliability for all adult age groups.
• Brain on Track® on tablet is a reliable digital solution for cognitive screening and monitoring.
