Episodic Future Thinking and Weight-Loss

The study program is organized into 20 sessions. There is a mix of group sessions, individual family in-person sessions, and individual family phone sessions. Each session is outlined below:

Session 1 will be an in-lab screening session to ensure participants are eligible to participate. During this session, participants will have their height and weight measured and complete surveys: Eating Disorders Examination Questionnaire (EDE) for parents, Kid's Eating Disorders Survey (KEDS) for kids, Sociodemographic, and a clinical interview. Participants will also be instructed to track their eating and physical activity in MyFitnessPal.

Session 2 will be a group workshop. Families will learn the core components of the program in presentations by the research staff. The workshop will also include activities to keep the families engaged and a meal will be provided. If the participants attend the workshop, successfully logged in MyFitnessPal, and still want to participate, they will be randomized to a treatment group and scheduled for a baseline session.

Session 3 will be a baseline session. Participants will have their height, weight, and delayed discounting (DD) measured to establish baseline data. Participants will also complete baseline surveys including: Consideration of Future Consequences Scale (CFCS), Palatable Eating Motives Scale (PEMS), Relative Reinforcing Value, and Living to 75 assessment. Participants will also create their first EFT or HT cues.

For EFT cue generation, participants will talk about a specific future positive event where they imagine themselves in vivid detail. To generate the cues, participants in the EFT group will be given standardized instructions asking them to think about and list specific events that they are looking forward to in the future (ex: parties, holidays). Participants will be instructed to generate the EFT cue by describing their events, including a detailed description of themselves at the specific event. After the participant has created their cues, they will save their cue for later use in the intervention.

To control for the timing and attention of the EFT cue, participants in the HT group will generate cues that include specific nutrition statements that they feel will be of personal benefit. To generate the cues, participants in the HT group will select from a list of nutrition statements that they feel will be personally useful in making healthy decisions.After the participant has created their cues, the participant will save their cue for later use in the intervention.

Sessions 4-19 will be intervention sessions split into 2 phases:

Phase 1:

Sessions 4-11 will be in person sessions between an individual family and a researcher. Participants will have weight measured, do the thought training program, and talk to staff about progress in the program. Phase 1 is when the monetary incentives program will be implemented.

Phase 2:

Sessions 12-19 will be phone sessions between an individual family and a researcher. Participants will do the thought training program and talk to staff about progress in the program.

During both phases of intervention, participants will be encouraged to send weekly weights from a provided Bluetooth enabled scale. Participants will also be asked to log their activity related to the program in the MyFitnessPal app. Researchers will access the information and send feedback to the participants (via text, phone, and/or email) to help them succeed in the program.

Session 20 will be an in person session between an individual family and the researcher. This session will act as a follow-up session as there will be an 8 week gap between Session 19 and Session 20 where there is no study intervention.
