Brief Summary:
The goal of this multiple baseline experiment is to test the effect of a digital, gamified early intervention for eating disorders on body image flexibility and determine treatment dose. Twenty-four young women and girls (between the ages of 15-25) with eating disorder (ED) symptoms will be randomized to different baseline durations (varying between 2-6 weeks). Participants will complete eight 20-30 minute sessions of a multimedia application over 10 weeks using their home computer or mobile device. Body Image Flexibility (BIF) will be measured repeatedly using a multimodal assessment strategy (behavior, physiological and self-report) during baseline and treatment phases. The investigators will estimate the effect of the intervention on BIF and examine when change occurs and plateaus (with no discernable benefit for additional sessions) to determine treatment dose.

Arm Intervention/treatment
Experimental: Digital Intervention
Eight 20-30 minute sessions of an online, multimedia application
Behavioral: FlexED
Intervention consists of eight 20-30 minute sessions of a digital intervention based on Acceptance and Commitment Therapy (ACT). Participants learn skills of body image flexibility by following an avatar through a story line and completing interactive exercises.

Primary Outcome Measures :
  1. Change in body image flexibility as indexed by the Body Image - Acceptance and Action Questionnaire-5 (BI-AAQ-5) [ Time Frame: Baseline, 1, 2, 3, 4, 6, 8, 10, 12, and 16 weeks ]
    5-item measure assessing the ability to behave flexibly in the presence of negative thoughts and feelings about the body. Scores range from 5 to 35 with higher scores indicating greater flexibility.

  2. Change in High Frequency Heart Rate Variability (HF-HRV) [ Time Frame: Baseline, 1, 2, 3, 4, 6, 8, 10, 12, and 16 weeks ]
    Heart rate variability during provocation of body image distress; greater variability indicates an increased capacity to modulate arousal and distress.

  3. Change in biased processing of body image stimuli relative to neutral stimuli [ Time Frame: Baseline, 1, 2, 3, 4, 6, 8, 10, 12, and 16 weeks ]
    Biased processing of stimuli is assessed using an emotional Stroop task with body image and neutral stimuli. Improvements are indicated by changes in reaction time and fewer errors.
