"The authors would like to acknowledge the administrative support of the Department of Psychology at Uppsala University necessary to perform the research presented. The present study protocol has described a clinical trial of iCBT for individuals with symptoms of ADHD and is believed to increase the current understanding of how to provide psychological treatments for a particular group that typically receive very little support apart from pharmacotherapy. The aim is to provide an effective online intervention that might increase access for those who do not receive help, and could, if found beneficial, become an important addition to medication, increasing quality of life and managing symptoms of ADHD, anxiety, depression, and stress.
