The purpose of this study is to test the feasibility of disseminating an intervention broadly. "FlexED" is a digital gamified intervention targeting eating disorder symptoms in young women and girls at risk by changing how they experience thoughts and feelings about their body. The digital intervention is based on Acceptance and Commitment Therapy (ACT).
Participants complete seven 20-minute sessions of the intervention using their smartphone over about 8 weeks. Participants also complete questionnaires bi-weekly as they go through the intervention. A final measurement is taken one month after the last digital intervention session. These surveys are all conducted online. Participants are in the study for up to 12 weeks.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
