Title: SMART Weight Loss Management
Brief Summary: The overall objective of this study is to use an innovative experimental approach, the SMART (Sequential Multiple Assignment Randomized Trial), to determine the best way to sequence the delivery of mHealth tools and traditional treatment components in a stepped program of obesity treatments. The SMART approach is a highly efficient strategy for identifying and constructing efficacious adaptive interventions: it accommodates sequential decision-making based on the participant's response to early weight loss treatment components. The proposed treatment package begins with the least expensive components, and for participants identified as treatment non-responders, provides sequential step-up of additional treatment components. By sequentially delivering treatment components based on participant response, SMART permits achievement of the target outcome, weight loss, with least resource consumption and participant burden.
