Eksperimentel: 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.
|
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.
|
|
Aktiv komparator: Active Control Condition
Participants in this condition will receive minimal intervention designed to reflect "usual care" for weight loss maintenance.
|
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.
