Purpose

This trial will test the effectiveness of a weight loss maintenance intervention designed to help participants respond more adaptively to weight regain. Participants will be randomly assigned to one of two conditions. In one condition, participants will receive brief exercises (e.g., written reflections, videos) sent to through a smartphone app immediately after they regain weight or miss a weigh-in. These exercises will use mindfulness, acceptance, and self-compassion strategies to help participants stay motivated for their long term goals, even when weight regain feels demoralizing. In the comparison condition, participants will receive weekly reminders of standard weight control strategies strategies.

ArmDescriptionAssigned Intervention
Experimental
JITAI Condition 		Participants in this condition will receive a 6-month weight loss maintenance intervention that uses mindfulness, acceptance, and self-compassion strategies to respond to weight regain.
  • Behavioral: JITAI Combined with psychological intervention
    For six months, participants will receive a just-in-time adaptive interventions via a smartphone app immediately after they gain weight or they skip a weigh-in (according to a specific algorithm). Interventions will engage participants in mindfulness, acceptance, and self-compassion-based (MASC) strategies through different modalities (e.g., writing exercises, videos, audio reflections). They will take approximately 1-10 minutes. Participants will also attend an introductory workshop, during which they will receive the instructions weigh daily, learn the importance of quickly responding to weight regain, and be introduced to MASC strategies. They will also attend two booster workshops during the 6-month period.
Active Comparator
Active Control Condition 		Participants in this condition will receive minimal intervention designed to reflect "usual care" for weight loss maintenance.
  • Behavioral: Active Control
    For six months, participants will receive weekly, automated messages via a smartphone app with reminders of standard behavioral weight control principles. Participants will attend an introductory workshop, during which they will receive instructions to weigh daily and learn the importance of responding to weight regain.
