Digital media and wellbeing among children and adolescents in Ticino



MEDIATICINO is an eight-year research project conducted between 2014 and 2021. It investigates the impact of new media on the well-being of students in Ticino during their transition from preadolescent (approximately 10 years) to adolescent age (approximately 18 years). This longitudinal study consists of an annual survey among almost 1400 students (from 2014 to 2021), a biennial survey among their parents (from 2014 to 2019), and the integration of students' year-term grades (from 2014 to 2019). In 2018 and 2019, thanks to funding from the Swiss National Science Foundation, the researchers had the opportunity to collect objective information on screen time and app usage directly from students’ smartphone, through the Ethica app. To underline this innovative aspect, the project has been renamed in “MEDIATICINO2.0”. The project is carried out in collaboration with the Department of Education, Culture and Sport (DECS), responsible for all public schools, and the two private schools Istituto Elvetico and Collegio Papio.
