This study examines how possibilities for agency are designed into online youth counselling services, as well as how such possibilities are addressed by young prospective users during the design of the services. The data are drawn both from the design of a national website for youth clinics in Sweden and from a design project developing e-services for local youth clinics in a Swedish municipality. The agency of young users is here treated as a key concern for understanding how user empowerment is accomplished through the design of websites and e-services. Using combined research materials (i.e. two websites and focus group meetings), this study demonstrates how design features may both facilitate and restrict young people’s involvement and control over sensitive and private issues. In addition, we demonstrate how the designed possibilities for empowerment may allow young users to critically approach and effectively use such services.
