The present study sought to explore the types of social support being provided to adolescents with cancer accessing a computer-mediated support group. Three hundred and ninety-three messages posted to a computer-mediated support group aimed at adolescents with cancer were coded for instances of informational and emotional support and then subjected to thematic analysis. Analysis revealed frequent instances of both informational and emotional support provision and sub-themes included 'treatment concerns', 'losing friends' and 'struggling with school'. Adolescents were also found to be frequently accessing the group to make requests for social support. It is concluded that health professionals need to tailor the services they provide to adolescent patients more appropriately.
