This paper describes a platform for administering questionnaires on smart-phones and tablets. The project arises from the need of acquiring data for monitoring the outcomes of different homecare interventions. First a model has been defined for representing questionnaires, able to support adaptivity in the dialog with the user and enforce some simple consistency rules for checking his input. Then an application has been implemented able to run instances of those questionnaires. It downloads questionnaires over the air in terms of XML files from a server and stores them locally into a local repository. At that point questionnaires become available for the user who can select which one to fill in according to his needs and the specific treatment protocol. A questionnaire may be filled in all at once or be completed in subsequent steps over time since the input provided is persisted on a local database. Finally, when a questionnaire is closed all the answers are transparently synchronized to a server for further evaluation or statistical purposes. [For the full proceedings see ED562140.]
