The Effects of Heart Rate Variability Biofeedback on College Students With Disordered Eating

Baseline surveys contains a series of scaled questions, including sociodemographic variable (age, sex, etc), profile of mood states, perceived stress scale, Eating Loss of Control scale, Eating Disorder Examination Questionnaire, Brief Resilience Scale- BRS,Heart Rate Variability and coherence measures

Participants randomized to the intervention arm will receive a standardized HRV sensor and accompanying smartphone app, and a 30-minute HRVB training to use the biofeedback signals to generate a resonant frequency pattern of HRV (coherence) after collecting data at baseline in person. Participants will be asked to practice their HRVB skills at home for 10 minutes for two weeks.

Participants randomized to the waitlist control arm will receive educational materials on eating disorders and stress management and will be sent home with these materials after completing the baseline survey. They will be encouraged to read the materials over the next two weeks before coming in for T2 survey.
