Summary
This study will conduct a randomized trial to evaluate the efficacy of a theory-based, individually tailored, multi-technology intervention on increasing physical activity in Latina adolescents, compared to a control group receiving only a physical activity tracker (a Fitbit). The investigators will recruit adolescent (age 13-18) Latinas (N=200) who are currently underactive to participate in the 12-month trial. Those randomized to the Intervention arm will receive a one-on-one counseling session and access to an individually tailored multi-media website. Key intervention components will be reinforced through text messaging to aid goal setting, a physical activity tracker (Fitbit) to set goals, track and log activity, and access to a study Instagram account to reinforce exposure to web content. The primary outcome will be increases in moderate-to-vigorous activity between baseline and 6 months. Secondary outcomes will include changes in activity at 12 months, potential mediators of the intervention, costs of delivering the intervention, behavior change trajectories from continuous data from Fitbits, potential moderators, and changes in physiological and psychological variables.
