Interventions
The GO-OUT study was a 2-group RCT conducted in Edmonton, Winnipeg, Toronto and Montreal, Canada. Ethics boards from the four academic institutions associated with the research sites approved the study and participants signed a consent form.All participants were asked to attend an interactive workshop in groups of up to 18 participants prior to randomization [Participants in the WR group received a phone call (or e-mail if participants could not be reached) from the study coordinator each week for 10 weeks after attending the workshop. These scripted reminders were designed to reinforce information that was covered in the workshop, encourage participants to work towards their goals for outdoor walking, and answer questions.The OWG program consisted of twice-weekly walking sessions held in neighborhood parks for 10 weeks. Sessions for the OWGs ran during summer months from June to August, except in site 4, where three groups ran August to early October. The OWG program was based on theory; activities were designed to build competence in established dimensions of community mobility including distance, temporal factors, terrain, physical load, attentional demands, postural transitions, and traffic density [
