Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants: Nurses, midwifes and patient assistants (N = 168) will be recruited from four hospitals in Perth, Western Australia. Intervention: Participants will be randomised to one of the three intervention conditions including different behaviour change techniques (BCTs): (1) motivational, (2) motivational and self-regulatory, (3) motivational, self-regulatory and habit formation, all an online behavioural intervention to encourage physical activity in their own time.
There will be six fortnightly online sessions (approximately half an hour each) delivered over three months. The sessions are designed by sports and psychology experts. Participants will receive tailored feedback based on their answers to short surveys that they complete at the beginning of each session. Study participants will receive email reminders to complete the sessions, followed by a phone call from a trial coordinator in case of low adherence to the procedures.
The study will compare the unique and additive effects of three forms of the tailored intervention on study outcomes based on different techniques from behavioural theory. One form will adopt techniques that focus on motivational processes; other one will add intentional self-regulatory processes while another will add the development of habits.
In the motivational condition participants will be asked questions about their main motives to be physically active. Based on their responses, they will receive feedback including BCTs that boost their motivation and help them specify and reach their goals. In the self-regulatory condition additional techniques supporting self-monitoring and regulation will be added, e.g. feedback on performance and progress throughout the intervention. In the habit formation condition participants will receive all aforementioned intervention components as well as techniques relevant to habit development, e.g. emphasising need to repeat the same activity in the same context, and establishing routines.
Participants will see relevant feedback on the computer screen once they have answered short surveys. For instance when they are asked about main barriers to be physically active, they will receive advice on how to overcome the barriers that they have selected. Participants self-reported physical activity will be measured at the beginning of each fortnightly survey and the feedback will be also tailored accordingly to the changes in physical activity.

Comparator / control treatment
Participants assigned to the control condition will be provided with information about physical activity recommendations and a library of short information materials relevant to the physical activity with the star rating system. It will be a static and non-personalised website; as previous research has reported these as ineffective in increasing physical activity.

Efficacy
Statistical methods / analysis
The proposed sample size (168) follows guidelines for appropriate sample sizes for pilot trials. The statistical analysis will include multiple mediation analysis. The changes from baseline to follow-up for each participant in each condition will be analysed. Depending on the number of missing data points, appropriate statistical methods will be used to account for missing data. Data will be tested for linearity and normal distribution; correlation among participants from the same hospital ward will be controlled for.
