This is a randomised controlled trial of internet based program termed the Panic Program for treatment of Panic Disorder. The Panic Program is a package of six Cognitive Behaviour Therapy lessons focussing on Psychoeducation, Controlled Breathing, Cognitive Therapy, Behavioural experiments and graded exposure. Participants read the first 3 lessons in week one then fortnightly thereafter. After each lesson they will download "Homework assignments" to complete in their own time. Lessons are completed in the location of the participants choice; whether that be home, work or even internet cafe. In addition they participate in an online forum for futher education and support from peers and the treating clinician. They also have additional support from the treating clinician via email; responding to questions or providing feedback to homework assignments. The program will take 9 weeks in total to complete. All participants will meet Diagnostic and Statistical Manual of Mental Disorders, 4th Edition (DSM IV) criteria for Panic Disorder. The control group will be treated after the intervention group complete the course.

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 a structured diagnostic interview (MINI). The interviewer is unaware prior to the interview whether the patient will be included or excluded, nor to which group the participant will be allocated. After the interview participants will be randomly allocated to treatment or control group using a list generated prior to the study. Allocation is not concealed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A randomization list will be generated prior to the study using computer software (www.random.org).
