Scaling up Behavioral Weight Loss Opportunities for Cancer Survivors With Overweight or Obesity in Maryland: A Randomized Trial With Adaptive Interventions (Helpline for Weight Loss)
The objective of the HELPLINE Weight Loss Program is to determine the comparative effectiveness of two active multi-component, augmented interventions for cancer survivors with overweight or obesity who do not achieve early weight loss goal in the initial intervention period (termed, early non-responders). The core study design is randomized controlled trial with adaptive intervention. 1. CORE Helpline in all participants (first 2 months) 2. Extended Helpline in early responders (additional 6 months) 3. Enhanced Helpline in early non-responders (additional 6 months) 4. Intensive Helpline in early non-responders (additional 6 months)
