Behavioural and Cognitive Change During a Self-Guided Online Cognitive Behavioural Therapy Course for Anxiety and Depression: An Open Trial

All participants will complete 5 lessons of an internet-delivered cognitive behaviour therapy (iCBT) treatment, the Wellbeing Course, focusing on the management of anxiety and depression. All 5 Lessons will be administered online (via the internet); each lesson will be completed every 7 to 10 days. Each lesson will take about 15 minutes to complete. Participants will also have access to summaries of each lesson, and will read anonymous stories about other people with depression and anxiety, taking a further 20 minutes per summary. All participants will also receive weekly reminder emails informing them when lessons become available. The duration of the reminder emails will take an additional 2 minutes to access and read. The duration of the program is 8 weeks. Study questionnaires will be administered at application, pre-treatment, during the treatment, post-treatment, and 3 months post-treatment. These questionnaires at application, pre-treatment, post-treatment and 3-months follow up will take about 10-15 minutes to complete. The questionnaires administered during the treatment will take approximately 3 minutes to complete. The software presenting the iCBT treatment course will also record information to inform adherence to the intervention (e.g. lessons completed, download history of other treatment materials in the course, number of logins, and duration of logins)
