Description of intervention(s) / exposure
Participants will be randomly assigned to one of two groups: 1) Treatment with clinician-assisted Internet based Cognitive Behavioural Therapy for Generalised Anxiety Disorder (GAD) and/or depression, or 2) Waitlist control. All participants will meet Diagnostic and Statistical Manual of Mental Disorders 4th Edition (DSM-IV) criteria for GAD and/or Major Depressive Disorder. All group 1 participants will separately complete 6 lessons of Internet based treatment about the management of symptoms of GAD and depression. One lesson will be completed every 7 to 14 days (it will become available after the preceding lesson has been completed, with a minimum of 7 days between lessons and a maximum of 14 days). Each lesson will take about 15 minutes to complete. Group 1 participants will have access to summaries of each lesson, homework exercises, extra resources, weekly reminder emails, and one-on-one contact with the Clinician (Clinical Psychologist) by telephone or email in the first 2 weeks, then as required. The duration of the program is 8-10 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, mid-treatment, post-treatment, at 3 months post-treatment, and the K10 pre-each lesson. These will take about 20 minutes to complete. The treatment materials are based on cognitive behavioural techniques.

Treatment
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.
Masking / blinding

Summary
Brief summary
We recently completed an RCT pilot study of an internet-based transdiagnostic treatment for anxiety disorders and for GAD, panic, social phobia and depression. Adherence throughout the program was roughly equivalent to that of our previous internet-based disorder-specific programs (76%), and post-treatment results finalised in January 2010 support the efficacy of this initiative.

We are interested in further investigating the efficacy of internet-based treatments for a population of people suffering from GAD and/or depression.
