- Behavioral: Multi-technology MVPA intervention
- Registration Number
- NCT06595056
- Lead Sponsor
- University of California, San Diego
- Brief Summary
This study will test a physical activity intervention for Latina teenagers. Investigators will recruit 200 Latina adolescents who are currently under-active to participate in this 12-month study. Participants will be referred to the study by their primary care provider. Half of the participants will be randomly selected for the Intervention group, and will receive an individual counseling session and access to a personalized website. These participants will also receive a Fitbit activity tracker to help with goal setting and monitoring, plus weekly text messages and access to the study Instagram account to remind participants to be physically active. Those assigned to the control group will receive the Fitbit activity tracker.
- Detailed Description
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 study team will recruit adolescent (age 13-17) Latinas (N=200) who are currently under-active 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.

- Primary Outcome Measures
Name Time Method Meeting guidelines for physical activity 6 months Proportion of participants meeting guidelines of 60 min/day of moderate to vigorous physical activity (MVPA) measured by accelerometers
- Secondary Outcome Measures
Name Time Method Maintenance of MVPA 12 months Proportion of participants meeting guidelines of 60 minutes/day of MVPA measured by accelerometers.
Processes of Change for Physical Activity (POC) 12 months Questionnaire that tracks cognitive and behavioral processes related to MVPA change
Stages of Change for Physical Activity (SCPA) 12 months Questionnaire that determines what stage of exercise engagement the participant is currently in (precontemplation, contemplation, preparation, action, maintenance), and is used to stage-match treatment.
Self-Efficacy for Physical Activity (SE) 12 months Questionnaire that measures self-efficacy to become physically active across diverse contexts
Social Support for Exercise (SSE) 12 months Questionnaire measuring social support specifically in relation to exercise with three subscales (friends, family, rewards/punishments)
Outcome Expectations Scale 12 months Questionnaire that measures the beliefs regarding the consequences of physical activity participation
Technology Engagment 12 months Tracks activity on the study website (logins, goal setting, questionnaires answered), Fitbit activity (days worn, sync frequency), texting activity (% of interactive texts responded to), Instagram activity (views, likes)
Neighborhood Environment Walkability Scale for Youth (NEWS-Y) Baseline Questionnaire that measures perceptions of neighborhood environment including recreation facility availability, pedestrian traffic safety, and walking facilities
Vital Signs 12 months Height, weight, resting blood pressure
Perceived Stress Scale (PSS) 12 months Questionnaire used to assess stress levels
Demographics Baseline Age, race, parent education and income, marital status, acculturation
Physical Activity Enjoyment Scale (PACES) 12 months Questionnaire that assesses level of personal satisfaction from physical activity
Childrens Depression Inventory (CDI) 12 months Questionnaire that measures affective, cognitive, motivational, and somatic symptoms
