Interventions

The web app is designed as an efficient and easy-to-use app configurable to personal preferences. Each day participants receive a text message on their smartphone with a link for the daily cSMS questionnaire. The questionnaire addresses the same questions as the questionnaire in the standard intervention, but the format is different, and some shortcuts makes it easier to answer. When the questionnaire is answered, the web app gives access to different features. The following features distinct the motivation-enhancing intervention from the standard intervention (1) only complete the entire questionnaire on days with symptoms, (2) integration of grass pollen counts and forecasts, (3) showing personal response rate, (4) access to own data via a graph, (5) advice against grass pollen allergy, (6) status of the study, (7) individually choosing the time of response, (8) option to download an icon for the home screen and (9) contact information. The development is an ongoing iterative process

Intervention

Each day participants receive a text message on their smartphone with a link for the daily cSMS questionnaire. When the questionnaire is answered, the tab needs to be closed.
