The purpose of this study was to examine access to and use of Internet by 97 physically disabled adolescents. Four main objectives were to: (1) explore frequency and nature of Internet use and the role of care givers, (2) compare these results with non-disabled adolescents, (3) explore associations between access to and use of Internet and adolescents variables, and (4) examine differences between care givers in the guidance of adolescents concerning their Internet use. Outcomes on a questionnaire were compared to those from a control group consisting of 1566 non-disabled adolescents. No differences in access to Internet between physically disabled and non-disabled adolescents were found. In addition, the most common online activities were similar for both groups. Physically disabled adolescents were more often warned by their parents about the risks of Internet and more often had rules at home than their non-disabled peers. Among the group of physically disabled adolescents, gender and environmental setting were found to be related to online activities. In addition, age was found to be related to the amount of rules at home. No associations were found between IQ and the access to and use of Internet. Finally, parents of physically disabled more often warn adolescents and more often check their use of Internet than care staff. (Contains 6 tables.)
