Description of intervention(s) / exposure
Participants will be recruited, predominantly via social media, e-mail and random cold calling and randomised into one of 4 intervention groups.

Group 1a – Text-based computer-tailored physical activity program with self-reported physical activity
Group 1b – Video-based computer-tailored physical activity program with self-reported physical activity
Group 2a – Text-based computer-tailored physical activity program with wrist-worn physical activity tracker
Group 2b – Video-based computer-tailored physical activity program with wrist-worn physical activity tracker

All groups will have access to the TaylorActive website, and be asked to complete 8 modules on a weekly/fortnightly basis, in order to receive personally tailored feedback. The feedback will (either delivered as text on a webpage or as a personalised online video; and either supported by an activity tracker (Fitbit) or not)..

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)
Interested participants will be asked to complete an online registration form which details whether or not the are eligible and their contact information. Or they will be cold called and eligibility was assessed directly on the phone.

Once eligibility is assessed, participants are asked to complete an online baseline survey.

Once baseline data is complete, participants will be enrolled into the study and randomised.

The person who will determine if a subject was eligible for inclusion in the trial will be unaware, when this decision is made, to which group the subject will be allocated. Therefore allocation will be concealed.

The method of concealment is central randomisation by computer.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomization.com will be used generate a random sequence determining which participant would be allocated to what group.

Summary
Brief summary
Physical inactivity is responsible for the second largest chronic disease burden in Australia (6.6%) and costs the health care system $1.6 billion every year. Over 85% of Australians have access to the Internet, and while most users have embraced the advantages of fast broadband connections, little research has investigated how this can be used for health promotion. More recently, there has been a large uptake of advanced activity trackers (e.g. Fitbit) that provide accurate information about personal activity levels. The vast reach and low cost of innovative web-based interventions can contribute significantly to promote physical activity and prevent chronic disease on a population level.

Current web-based interventions often fail to engage participants long enough to achieve long-term behaviour change and health benefits. As such, innovative approaches, in tune with how people use the Internet today, are needed. Based on our previous research we aim to demonstrate that highly personalised (e.g. tailored to age, gender, activity levels and self-efficacy) physical activity advice that is based on feedback from an advanced activity tracker is more credible, engaging and effective to increase physical activity when compared to personalised physical activity advice that is based on a self-report measure (e.g., the Active Australia Survey).

Study aims are:
To study the effectiveness of the computer-tailored physical activity intervention supported with Fitbit activity monitors relative to a computer-tailored physical activity intervention without Fitbit support (4 group, 3 month randomised trial) on:
a. The primary outcome measure of change in physical activity.
b. The secondary outcome measures: credibility and acceptability of the personalised advice, the engagement with the intervention (assessed through website usage statistics) and intervention feasibility.
