Plain English summary of protocol

Background and study aims
Interventions (or programs) to promote physical activity (PA) often fail to show long-term effects, and the suspicion is that PA behaviors need to become habits in order to be maintained. Recent research on habits indicates that habit formation may be facilitated by repeated and consistent environmental cues. The aim of this study is to test how well text messaging cues (SMS) do at getting people into the habit of doing PA in the workplace.

Who can participate?
Employees of the Française des Jeux compagnie that do not currently do any exercise, have medical clearance to start an exercise program and are able to attend a fitness center for a 60 minute session twice a week.

What does the study involve?
The employees are randomly allocated into one of two groups. Those in group 1 (PA group) take part in a 28 day supervised PA program. Those in group 2 (PA+SMS group) take part in the same program and are sent text messaging cues before their PA sessions. The exercise habits of each participant is assessed every week by the Self-Report Behavioral Habit Index using an online application.

What are the possible benefits and risks of participating?
Not provided at time of registration.

Where is the study run from?
Francaise des Jeux, Vitrolles (France)

When is the study starting and how long is it expected to run for?
June 2013 to June 2015

Who is funding the study?
Société Diagana sport santé (Diagana sport santé company) and Fondation Française des Jeux (Fondation of Française des Jeux) (France)

Health condition(s) or problem(s) studiedWe studied sedentary employees at their workplace.
Intervention1. Experimental: Physical activity + SMS group:
The group attended 2 sessions of supervised physical activity sessions and received 4 SMS per week.
All sessions were held at the same time of day (during lunch break) and on the same day of the week (Tuesday and Thursday). One session consisted of Nordic walking and the other consisted of circuit training. The session contents were individualized according to each individual's PA level using a heart rate monitor. The PA+SMS group received four text messages per week, always at the same time to favor cue consistency. For each session, one SMS was sent the evening before (7 pm) to remind and help the participants to plan their behavior
2. Active Comparator: Physical activity:
The physical activity group attended two one-hour PA sessions per week supervised by two professional PA instructors. One session consisted of Nordic walking and the other consisted of circuit training.
Intervention typeBehavioural
Primary outcome measurePrimary Outcome Measure:
1. The strength of the PA habit was measured using the Self-Report Behavioural Automaticity Index (SRBAI)
Time Frame: from October 2013 to June 2014, assessed every week. Participants received an email every Thursday at 2 pm from the communication service of their company to ask them to complete the SRBAI for the behavior using an online survey-managing website. If they missed to report, they received another email to remind them on the following Monday at 2 pm. They provided their answers using a 10-point Likert scale, with higher scores indicating stronger habit strength.
Secondary outcome measuresLevel of Physical activity using IPAQ (International Physical Activity Questionnaire). Time Frame: on October 2013, June 2014 and June 2015. Participants has to answer the IPAQ questionnaire by email three times to evaluate their physical activity level.
