This study uses focus groups and a questionnaire to examine the information-seeking behaviours of Swedish upper secondary school students. Focus group interviews were conducted among students aged 17-20 at four Swedish upper secondary schools in two different cities. The interviews focused on how the informants themselves experienced their information seeking. In addition, a survey focused on the opinions of upper secondary school teachers regarding the source use of their students. The research questions considered were: What kind of information-seeking behaviour characterizes Swedish upper secondary school students? What kind of information do Swedish upper secondary school students seek when it comes to issues where corporations can be of assistance? How do Swedish upper secondary school students prefer to have information presented? The results of the study provided some valuable insights concerning these questions. The students turned out to use the Internet, and most often Google, in much of their information seeking. However, human contact in the form of face-to-face conversations or presentations was also considered highly important. Furthermore, the information-seeking skills, or information literacy, of secondary school students are not emphasized in their education. The study was performed in cooperation with AstraZeneca in the hope of the results providing the company with valuable information regarding one of their intended target groups.
