Description of intervention(s) / exposure
Participants will be randomly assigned to one of two groups: 1) Treatment with clinician-assisted Internet based treatment for panic, or; 2) Waitlist control. Treatment will be completed individually via the internet based CBT course (ie not as part of a group), and any clinician (Psychiatrist) assistance will be one-on-one. All participants will meet Diagnostic and Statistical Manual of Mental Disorders 4th Edition (DSM-IV) criteria for Panic Disorder with or without Agoraphobia. All group 1 participants will complete 5 lessons of Internet based treatment about the management of symptoms of panic. One lesson will be completed every 7 to 14 days (patients can move through to the next lesson every 7 days, however, the lesson will be available for up to 14 days). Each lesson will take about 15 minutes to complete. Group 1 participants will have access to summaries of each lesson, homework exercises, and will receive weekly reminder emails. Contact with the clinician (a Psychiatrist) will be as and when required, and contact content will vary based on the demands of individual patients. The duration of the program is 8 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, mid-treatment, post-treatment, and 3 months post-treatment. These will take about 20 minutes to complete. The treatment materials are based on cognitive behavioural techniques.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants apply on line, followed by a telephone interview to confirm diagnosis via the Mini-International Neuropsychiatric Interview (MINI 5.0.0), a structured diagnostic interview. Participants will be randomized using a list generated prior to the study. Allocation concealment will occur in the following way: A staff member not involved in the clinical trial will generate the sequence using computer software, and place each choice in a sequentially numbered, opaque, sealed and stapled envelope.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomisation list will be generated prior to the study using computer software.

Summary
Brief summary
Our previous research indicates that the Panic Program, an Internet-based treatment program for people with Panic Disorder with or without Agoraphobia is effective at helping people to learn to manage their symptoms of panic.

The study described here aims to find out whether therapist support is required for people to successfully complete the Panic Program.

We expect that people completing the Panic Program without therapist support (but who receive weekly telephone reminders) will still benefit, but not as much as those receiving the usual levels of therapist support.
