Brief summary

The purpose of this project is to explore whether a clinician-guided treatment program can help to reduce anxiety symptoms in a population of mature adults (aged 60-75), when administered over the internet. A secondary purpose is to determine how acceptable people find this form of treatment. The study will inform how services can best improve future treatment programs for mature adults with anxiety.

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.
