Digi&Mind: Development and validation of a multi-domain digital cognitive stimulation program for older adults with cognitive decline

Abstract Older adults present a decline on their cognitive function. Digital cognitive interventions are related to the maintenance of cognitive function and are associated with better health-related outcomes. This study aims to describe the development process of a multi-domain digital cognitive stimulation program for older adults with cognitive decline. The digital program was developed in four phases: preliminary phase (conceptualization), modeling (experts panel), field test (usability tests), and consensus conference. To ensure software suitability the development process followed also software guidelines for mobile and web applications for older adults. The result was the Digi&Mind digital platform made of a mobile application a backoffice web application. The backoffice web application usability test was conducted with 7 healthcare professionals through the Post-Study System Usability Questionnaire System (PSSUQ). The mobile application test was conducted with 4 older adults and 7 professionals through direct observation user testing. Healthcare professionals considered that the system, the information and the interface had quality. Older adults considered the mobile application as appropriate, useful and easy to use, despite of their low digital experience.
