The South Australian Digital Youth Survey (DYS) is a world-first longitudinal project exploring how adolescents use digital technology, and how this use changes over the course of adolescence. The project examines the links between how adolescents use technology and pathways into cyber risk-taking. In studying these links, this project seeks to identify the technical, social, and individual circumstances by which adolescents get drawn into cyber risk-taking. Understanding more about these circumstances will inform the development of prevention measures to mitigate such risk.
