Introduction: Internet is an integral part of everyday life today. In Sweden 98% of adolescents are reported using internet. However, adolescents with intellectual disabilities are often excluded in national surveys, since questions are not adapted for the target group. Statistics remain therefore limited regarding internet-use among adolescents with intellectual disabilities. Objectives: To investigate and describe internet-use among adolescents with intellectual disabilities through an adapted version of a nationwide survey in Sweden. Method: A cross-sectional study was conducted using an adapted version of a survey from the Swedish Media Council on media-use among adolescents. Cognitive adaptations were included and it was accessible through the web and in paper. The sample was drawn from three municipalities using a total-selection of pupils in secondary- and upper secondary special schools. 265 surveys were sent out and the response rate was approximately 32%. Data was analyzed through descriptive statistics. Results: The result gives demographic data on the participants and descriptive statistics on the access to devices for internet-connection. Further, data are provided on activities done in leisure time and whether internet is used or not, together with perceptions of doings on internet from the participants. Conclusion: Stepwise adaptations of the survey with different levels of cognitive support enabled the participation of adolescents with intellectual disabilities and the result gives increased knowledge of internet-use among adolescents with intellectual disabilities. Finally, future comparative analysis are possible due to the national survey being used implying the voices of adolescents with intellectual disabilities being heard.
