B. Procedure

The survey was conducted online, using the software SoSciSurvey, and it was posted on the official website of TRIPS project. It was accessible to users with visual impairment who use screen readers. The survey could be completed by persons with disabilities or by another person answering on their behalf. Respondents who had no disability were excluded from participation by means of a filter question, which leads directly to the final page of the survey. Completing the survey took about 20 to 30 minutes. To avoid missing data, all questions were mandatory.

Invitations informed users about the purpose of our study and about the TRIPS project overall, as well as about the projects’ data management policy and practices, and the use and management of their data in line with the GDPR. Participants were also given contact details should they need to contact someone for clarifications and extra information. Participants were asked for their consent at the beginning of the study, although data was collected anonymously.

The survey was distributed locally to disability user groups in the seven cities via the local teams, in seven European project cities (Bologna, Brussels, Cagliari, Lisbon, Sofia, Stockholm, and Zagreb), and more generally through ENIL and other European-wide organisations working with persons with different disabilities and access needs. The survey was also actively distributed through ENIL’s social media pages and other channels, such as regular members’ mailing and the monthly newsletter. In general, more than 121 local, regional, and international organizations contributed to disseminating the survey in question.
