EVENTS
The theory-based Hombres Saludables intervention arm consisted of several components, including an intervention website, SMS text messages, private Facebook group, gym membership, and check-in phone calls. The behavior change strategies (eg, goal setting, problem-solving, and stages of change) were informed by the Social Cognitive Theory and the Transtheoretical Model [Participants in the intervention arm received 4 to 6 autogenerated SMS text messages each week. These SMS text messages included reminders to engage with the website intervention materials and activities, content related to social support, and suggestions to overcome PA barriers. In addition, participants could opt in to a private Facebook group that contained PA tips, events, and information. Moreover, participants could use the Facebook page to provide social support to one another. To encourage participation on the Facebook page, engaged participants were entered into a random prize drawing (US $25) conducted monthly. Participants from the New England area received a 6-month voucher for membership at a local gym franchise (or financial equivalent of US $60 for distant participants). Participants received a check-in phone call at 1 week and 1 month after study enrollment. During these calls, study staff ensured that participants received study materials and could use the internet resources, discussed goal setting, and answered participants’ questions.
