Another possible explanation of the variability in the evaluation of the 3 groups concerns their experience with technology.
The authors would like to thank the third parties of the project for contributing to data collection.
Of all users, 6 users (1 PwD, 1 informal caregiver, 4 professionals) participated only at baseline testing and were excluded from further analysis.
Number of satisfied people with dementia (PwD), mild cognitive impairment (MCI), and caregivers for each platform function, excluding the sign in function.
PwD appreciated some functions of the platform, such as the social networking service, and showed their interest to communicate with others; however, their scores for the ease of use of these functions underline their inexperience with technology.
PwD and caregivers were concerned about privacy settings and who had access to the information they uploaded.
The aim of the platform is to improve the quality of life for PwD or MCI and reduce caregiver stress.
Data from PwD, informal caregivers, professionals, and dementia experts were collected to rank the usefulness of the Rosetta functions and to collect information about improving the system.
Involving older people with dementia and their carers in designing computer based support systems: some methodological considerations.
The discrepancies between the usability scores of the 3 user groups can also be explained by the different needs of these groups.
Privacy issues about sharing information on Internet can be addressed with short statements explaining who can see this information while implementing in the platform all the regulations related with data protection and privacy at the European and national levels.
The questionnaires for PwD and caregivers consisted of 30 items, and the questionnaire for professionals included 15 items.
The lower scores of PwD indicate the need to adapt the interface and functionality of the platform to meet their needs, such as to simplify the interface for this group.
PwD and caregivers also suggested that the upcoming appointments should be presented in a chronological order (with the closest appointment on the top of the page).
When users provided a neutral or negative response to the quantitative questions, they were immediately asked to provide qualitative feedback about this function.
Caregivers suggested that no notification was better than a reject notification, if an invitation was not accepted, to avoid upsetting users.
MMD platform through ratings and feedback provided from PwD or MCI, primary caregivers, and health and social care professionals.
Simpler interventions can be developed for PwD with uncluttered interfaces and an appropriate number of functionalities so that end users will engage with the interventions.
Participants were tested at the Rouen University Hospital (France), at the Sant Andreu Hospital of the Sociosanitari Foundation of Manresa (Spain), at the Centro Diurno Anziani Licio Visintini (Italy), or at their own environment (United Kingdom).

This difference may reflect the age difference between the mean ages of the user groups since PwD were 20 to 40 years older than caregivers and professionals.
The discrepancies in the evaluations from PwD, caregivers, and professionals highlighted that these needs and preferences vary in each group.
PwD and caregivers have different needs and interests than those which may be anticipated by professionals and developers.
The results revealed significant differences in the usability scores of the 3 user groups, with caregivers and professionals rating the platform more useful and easy to use than PwD.
