The present study will be fully remote (virtual) and include observational design features (assessments) plus a clinical trial. All assessments will be completed using HIPAA-approved platforms (e.g., Qualtrics, MindLogger EMA platform). After screening via Qualtrics to determine eligibility (described below), participants will complete a cross-sectional survey via Qualtrics, followed by a baseline EMA period. During the baseline EMA period, participants will receive brief (3-5 minutes) surveys on their mobile devices 6 times per day for 7-days via the MindLogger app. During the baseline EMA period, participants will also be asked to wear non-invasive chest-worn Holter monitors (Polar H10 Holter monitors) that will capture their heartrate variability data. They will then complete the 4-week intervention (HRV bio or ED-JITAI treatment arms; see below), followed by a post-intervention 7-day EMA assessment period while they also wear the Holter monitors. Recruitment is expected to last for 1.5 years. In HRV-bio, participants will also complete a HRV biofeedback task via the Elite HRV app. In this intervention, participants will learn how to use their HRV data that they will see in real-time via the Elite HRV app to improve their HRV by engaging in an app-guided diaphragmatic breathing exercise. They will complete this exercise twice daily (morning, night). In ED-JITAI, participants will be prompted to complete focused, guided body scan tasks that will be sent to them via the MindLogger app. These guided tasks will be sent to them in the form of 1 of 3 brief (3-5 minute) videos via the MindLogger app. The body scans will be designed to promote participants' connection with, vs. distancing/distraction from, feared ED sensations (e.g., hunger, satiety, bloating). Participants will receive prompts to complete the body scans at times when they report via EMA that they are experiencing worse interoception than usual. "Worse interoception than usual" will be defined as participants' EMA-reported interoception scores during the intervention period that fall 1 SD or more above their baseline EMA-reported interoception levels.
