Study type
Interventional
Description of intervention(s) / exposure
The first intervention group (tailored advice only) will receive the Active For Life Program. The 12-week program consists of six, 30 minute fortnightly sessions of personally tailored advice on the Active For Life website. The personally relevant advice in each session will be based on older adults’ responses to a brief online survey and will use computer algorithms to immediately provide feedback based on participants’ responses. The intervention content will be underpinned by components of the Theory of Planned Behaviour and Social Cognitive Theory as both theories have demonstrated their effectiveness in changing health behaviours in older adults. As such, the sessions will deliver physical activity advice tailored to psychosocial correlates (e.g., self-efficacy, social support, barriers), participants’ current physical activity level, participants’ demographics (e.g., age, gender) and health status. In addition to the six personalised sessions, the website will include an optional exercise library with beginner strength, balance and flexibility exercise programs. An optional action planning tool that allows users to create their own physical activity plans will also be included. There will also be a contact and help page where users can ask questions about physical activity or the study. A second intervention group will be given access to the same program, but with Fitbit activity trackers to objectively track their activity. Their personalised physical activity advice will be based on Fitbit data, rather than self-reported physical activity.

Comparator / control treatment
The control group will be a wait-list control group. They will be given access to the Active For Life website to complete the research surveys, however the program features (personalised advice, action plans and exercise library) will be turned off for the duration of the trial. The control participants will be given access to all program features after they complete the last research survey.

Efficacy
Statistical methods / analysis
For the primary outcomes, generalized linear mixed models (GLMM) will be used, on an intention-to-treat basis (to account for missing data), to test for differences in physical activity by group, across the time points. The GLMMs provide unbiased estimates of the treatment effect under the assumption that data are missing at random.

Summary
Brief summary
The purpose of the study is to determine the effectiveness of personally-tailored, web-based physical activity intervention, with and without Fitbit syncing, targeted to inactive older adults (65+ years of age) in a 6-month randomised controlled trial . It is hypothesised that increases in objectively measured physical activity will be greater in both intervention groups compared to the control group and greater in the Fitbit and tailored advice group compared to the tailored advice only group at 12 weeks.
