Please be advised that due to the high volume of submissions, the ANZCTR is currently experiencing delays in processing submissions from those outside of Australia and New Zealand. As the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first. International submissions should allow additional time for registration. Apologies for any inconvenience caused.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be randomly assigned to one of three groups: Group 1: Waitlist Control (who will begin the program 9 weeks after the other Groups). This group will receive the same intervention as Group 3. Group 2: Self-Guided Group. This group will receive access to all the program materials including access to the 5 online lessons and homework assignments, to stories written by previous participants with symptoms of anxiety and depression, and access to additional written resources. Group 3: Self-Guided + Automatic Email Group. This group will receive access to all the materials provided to Group 2, but will also receive regular automatic emails to inform participants about new materials, upcoming lessons, and reminders to complete lessons.

All participants will receive online access to 5 lessons of Internet based education about management of symptoms of depression and anxiety. 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 homework assignments/summaries of each lesson, and will read anonymous stories about other people with anxiety and depression, taking a further 10 minutes per week. The duration of the program is 8 weeks. Participants in Groups 2 and 3 will be contacted 3 months and 12 months post program and asked to complete follow-up questionnaires. Study questionnaires will be administered at application, pre-education, post-education, 3-months post-education and 12 months post-education. These will take about 20-30 minutes to complete. The education materials are based on evidence-based cognitive behavioural techniques for managing symptoms of anxiety and depression.

Study design
Purpose of the study
Educational / counselling / training
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 randomly allocated to one of the three 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
Blinded (masking used)

Summary
Brief summary
This project is part of a research program funded by the NHMRC (No. 630560) to develop and evaluate Internet based transdiagnostic education and treatment programs for people with anxiety and depression. This project examines the efficacy of a 5-lesson education course for people with depression, social phobia and/or panic disorder (with or without agoraphobia) and/or generalized anxiety disorder. It also explores the relative effect of different types of reminders (none vs. automatic email reminders) on outcomes and acceptability to consumers. We expect that differences will be observed between groups in symptoms of anxiety and depression (Groups 3>2>1) and in acceptability to consumers (Groups 3>2>1) and in completion rates (Groups 3>2>1).
