Description of intervention(s) / exposure
Participants will be randomly assigned to one of two groups: 1)an immediate treatment group, or; 2) a delayed waitlist control group (beginning 9 weeks after the immediate treatment group begin. Participants will receive access to an 8 week internet-based treatment program.All participants will have at least mild symptoms of anxiety (GAD-7 total score >7). All participants will complete 5 lessons of Internet based treatment about management of symptoms of anxiety and stress. One 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 anxiety, taking a further 20 minutes per week. All participants will also receive automatic emails and brief weekly (<10minutes week) supportive telephone calls from a clinical psychologist.

Study questionnaires will be administered at application, pre-treatment, post-treatment, at 3-months post-treatment. These will take about 20-30 minutes to complete. The treatment materials are based on the Wellbeing Program, which teaches evidence-based cognitive behavioural skills.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants apply online, and those who meet inclusion criteria are administered a telephone interview to identify psychiatric diagnoses using the Mini Neuropsychiatric Interview Schedule (MINI 5.0.0). Participants are then randomly allocated to one of the two groups. Allocation concealment will occur by providing allocation details for each successive participant in a sealed envelope, which recruitment staff are required to open serially.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomized using a list generated prior to the study via a software program (www.random.org), at another site, in another country. The list will then be transcribed and details transferred to sealed envelopes.
Masking / blinding
