Design outcomes

Primary

Measure	Time frame
Average number of pedometer steps per day. This will be assessed before (from week 0 to week 1) and after (from week 1 to week 5) the intervention begins. Our objective measure of steps will be obtained using a Yamax CW-300 pedometer.	—

Secondary

Measure	Time frame
1. Frequency of visiting the study website. 2. Self-reported intention to do at least 10,000 steps per day will be assessed using two items on scales ranging from 1 (strongly disagree) to 7 (strongly agree): I intend to do at least 10,000 steps per day over the next 4 weeks I will try to do at least 10,000 steps per day over the next 4 weeks We will also assess in relation to doing at least 10,000 steps per day: 3. planning, effort and commitment using single items; 4. perceived behavioural control using two items; 5. self-efficacy using four items; 6. goal difficulty, goal importance and goal conflict using single items. 7. Type of motivation will be assessed using the BREQ-2 (Markland & Tobin, 2004; Mullan, Markland & Ingledew, 1997). 8. Self-monitoring using a single item	—
