Brief summary
This study is a single-arm behavioral weight loss intervention for emerging adult women with in-person assessments at 0 (baseline) and 4 months (post-treatment) in addition to EMA data collection regarding risk factors known to interfere with program engagement and weight loss in this high-risk population (e.g., sleep, psychological distress, life events).
Detailed description
This study will implement a 4-month Internet-based behavioral weight loss intervention in order to collect ecological momentary assessment (EMA) data that will shed light on real-time barriers to weight management. The intervention is evidence-based and adapted with respect to content and delivery mode in order to meet the needs of emerging adult women. Consenting and eligible participants will receive 1 virtual group session led by a trained interventionist followed by weekly emails directing them to an intervention website housing video and .pdf content, weekly text messages, emailed tailored feedback regarding their weight loss behaviors and progress, and a closed Facebook group to facilitate social support. All participants will be followed for 4 months with hybrid in-person/virtual assessments at 0 and 4 months; in addition, all participants will be asked to respond to EMA prompts throughout the 4-month intervention period (Week 2, Week 4, Week 7, and Week 13).
Interventions
BEHAVIORALReady SET Health
This behavioral weight loss intervention will span 16 weeks. The first session (Week 1) will be a virtual Weight Loss 101 group kick-off followed by 15 weeks of a technology-mediated program consisting of the following: weekly emailed content (videos and readings explaining key skills and strategies to produce weight loss) and weekly emailed tailored feedback (based on self-monitoring data from participants). A trained interventionist (coach) will lead the group session, provide weekly tailored feedback, and monitor participant progress.
