Description

The goal of study is to conduct a Multiphase Optimization STrategy (MOST) Preparation phase study to combine and pilot test candidate components for a group-based, remotely delivered weight neutral/healthy lifestyle intervention. Potential treatment components will include the following existing, evidence-based interventions; (1) mindfulness-based eating awareness training , (2) body acceptance program , and (3) a tailored intervention to promote enjoyment of physical activity. Weight neutral components will complement a Core intervention of standardized education on healthy diet (emphasizing the Mediterranean diet) and Physical Activity Guidelines for Americans (i.e., aerobic activity, muscle strengthening). This phase of the science is focused on pilot testing to ensure the target sample can be recruited and and that the novel combinations of treatment components can be delivered as intended. To make strategic use of resources, a fractional factorial design will be used to pilot test five conditions: the Core intervention alone and all possible combinations of the Core intervention + two or more of the weight neutral components. Men and women (n=50) with BMI≥25kg/m2 will be recruited and randomized in small groups (n=10) to receive one of the five conditions held online (each 12 weeks in duration).
