This project includes testing circadian reset technology (CRT) on frequency of binge eating in a sample of 40 individuals with binge eating disorder. Participants will be randomized to one of two groups. Both groups use a virtual reality (VR) headset for 10 minutes (5 upon waking, 5 before sleep) daily for 1 month. One group will use the CRT software on the headset and the other group will use a software intended to be a control. Measures will be taken at baseline and 1-month. The researchers anticipate that use of CRT will improve sleep quality leading to increased appetitive control.

Circadian Reset Technology
BehavioralCircadian reset technology is a software used on a VR headset in this intervention. The software is a passive viewing experience like a guided meditation that presents visual images.
VR Headset
BehavioralThe software used on a VR headset in this intervention is a passive viewing experience like a guided meditation that presents neutral images that mimics the sequence used in the CRT software.
Change in the total number of bulimic episodes
Binge eating frequency measured by Eating Disorder Examination Questionnaire (EDE-Q). The EDE-Q scores behavioral features of eating disorders by calculating the number of episodes and number of days on which the behavior occurs. The total number of bulimic episodes will be measured to determine binge-eating frequency. Scores will be calculated between baseline and 1 month. The EDE-Q is a 28-item self-report measure assessing eating disorder symptoms. Full scale from 0-6, with higher score indicates greater severity of eating disorder symptoms.
Change in Pittsburgh Sleep Quality Index (PSQI)
Sleep quality measured by Pittsburgh Sleep Quality Index (PSQI) is a 19-item assessment that measures sleep quality with questions about duration, latency, frequency/severity of sleep issues. Items are answered on a scale of 0-3. The final score is a total of all questions ranging from 0 to 21 with lower score indicating worse sleep quality and higher score indicating better sleep quality. Scores will be calculated between baseline and 1 month.
Change in Three-Factor Eating Questionnaire (TFEQ)
Appetite regulation (restrained eating, disinhibited eating, and predisposition to hunger) measured by Three-Factor Eating Questionnaire (TFEQ) assesses appetite using 51 questions summarized in 3 subscales: cognitive restraint, uncontrolled eating, and emotional eating. Each item is scored as 0 or 1 and then summed. Subscales Cognitive restraint of eating score 0-21, Disinhibition score 0-16, and Hunger score 0-14. Full scale scored 0-51, higher scores indicate higher levels of restrained eating. Scores will be calculated between baseline and 1 month.
Changes in default mode network
Change in Brain functional connectivity as measured by default mode network - This test measures the pattern of connectivity in the default mode network during rest. Strength of connectivity default mode network (DMN) will estimated at the network level and between individual nodes.
Change in Eating Loss of Control Scale (ELOCS)
Food-based impulsivity measured by Eating Loss of Control Scale (ELOCS) measures the degree to which eating episodes included the feeling of loss of control measured continuously over the prior 4-weeks. There are 18 items scored on 0-10 scale from "not at all" to "Extremely/Completely". For total score, severity questions are averaged to get a mean severity score ranging between 0-10. Higher scores indicate more loss of control. Scores will be calculated between baseline and 1 month. Baseline to 1-month
