Intervention/exposure
Study type
Interventional
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)..

The TaylorActive website is minimal and includes:
- A homepage - highlighting the 'Text' and 'Video' groups modules and action plans.

- A account page where participants can update their details.

The 8 modules will include and give tailored feedback on the following information:

Module 1 (Week 1)
- Overview of the TaylorActive Project.
- General questions: name, height, weight, gender, age.
- Module relevant questions: current physical activity levels, goal choice, self-efficacy regarding participating in physical activity.
- Physical activity guidelines for chosen goal provided.
- Current activity level (tailored to chosen goal)
- Setting a small goal to achieve before next week.

Module 2 (Week 2)
- Review small physical activity goal provided last week.
- Goal setting and Action Plans

Module 3 (Week 3)
- Review physical activity for prior week.
- Benefits related to exercise.
- Boosting your confidence.

Module 4 (Week 4)
- Review physical activity for prior week.
- Opportunity to change goal.
- Confidence, Motivation and Positive thinking.

Module 5 (Week 6)
- Review physical activity at week 6 with that at week 1.
- Habits.
- Relapse Prevention - Barriers to following through.

Module 6 (Week 8)
- Review physical activity for prior fortnight.
- Opportunity to change goal.
- Social Support.

Module 7 (Week 10)
- Review physical activity for prior fortnight.
- Active Lifestyle.
- Active Environments.

Module 8 (Week 12)
- Review physical activity for prior fortnight.
- Summary of activity over TaylorActive Project.
- Success Stories.
- Wrap up the program, highlighting some of the skills learnt.

Other information:
- The TaylorActive feedback is provided by Physical Activity Researchers.
- The TaylorActive intervention will span a 3 month period for all participants.
- Each participant gets the opportunity to choose a male and female 'Taylor' to provide their tailored feedback.
- Each module should take between 5-10 minutes to complete the questions.
- Each tailored feedback text should take between 5-10 minutes to read.
- Each tailored feedback video will last between 5-10 minutes.

The website will record each time a participant logs in to the TaylorActive site, how many web pages they visit and how long they are on the website for.

Participants will be sent emails to visit the website and complete the TaylorActive Modules and Action Plans. Up to 3 reminders will be sent for each module to be completed.

Change in physical activity measured through the Active Australia Survey
Timepoint [1] 300099 0
Assessed at baseline, 1 and 3 months

Continuous ongoing measurement from the time participants use the website the first time to the end of the study at 3 months post-baseline.
Secondary outcome [1] 329045 0
Change in Sleep assessed through 6 questions. This survey was designed specifically for this study as questions were taken from 3 different sources:

Q 1-4: 2nd page, 2nd paragraph http://www.cdc.gov/mmwr/PDF/wk/mm6008.pdf

Secondary outcome [2] 329074 0
Intervention feasibility (this is a process evaluation assessing for example: how many technical issues there were with the use of Fitbit, as well as how easy/hard participant recruitment was). All this will be assessed through information that is automatically fed back to the research team (e.g. participant reports technical issue, this is logged on a spreadsheet; recruitment: the cost, amount of effort and time needed to recruit participants; information about recruitment is logged in a spreadsheet)

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.
Masking / blinding

Efficacy
Statistical methods / analysis
As this is a pilot study, demonstrating proof of concept is deemed more important over conducting a fully powered trail.
Repeated measure ANOVAs with intention to treat or Linear Mixed Models will be applied to assess significant differences between groups for the different outcomes measures..
