All participants will meet Diagnostic and Statistical Manual of Mental Disorders 4th Edition (DSM-IV) criteria for GAD and/or social phobia, and/or panic disorder. All group 1 and group 2 participants will complete 8 lessons of Internet based treatment about the management of anxiety symptoms. One lesson will be completed every 7 to 14 days. Each lesson will take about 15 minutes to complete. Group 1 participants will have access to summaries of each lesson, and will receive weekly reminder emails. Group 2 participants will have access to summaries of each lesson, will contribute to an online forum moderated by a clinical psychologist or psychiatrist, and will receive weekly reminder emails. The duration of the program is up to 10 weeks, but participants will be contacted 3 months post program and asked to complete follow-up questionnaires. Study questionnaires will be administered at application, pre-treatment, post-treatment, and at 3-month post-treatment. These will take about 20 minutes to complete. The treatment materials are based on cognitive behavioural techniques
