Participant Flow

Participant milestones

Measure	Mindfulness The mindfulness intervention consists of 6 weekly sessions, blending material from the evidence-based Learning to BREATHE and Mindfulness-Based Eating Awareness Training manualized interventions. Sessions will focus on: experiential mindfulness exercises, such as mindful eating, loving kindness practices, breath awareness, and mindful movement; hunger and satiety awareness; improving responses to emotions; practicing acceptance and being non-judgmental; and tolerating negative feelings and sensations, including those related to hunger and cravings. Participants will be assigned brief homework exercises (approximately 10 minutes) daily in between appointments.Participants in this arm will also receive the usual care provided by the weight management clinic.

PRIMARY outcome

Timeframe: 6 weeks post study start date

We will assess participants' satisfaction with the intervention by having them complete a satisfaction survey at the end of the program to assess perceived helpfulness of the intervention and to elicit feedback on the various components. Participants respond to 6 questions (e.g., "I enjoyed being a part of this program") on a scale of 1 (strongly disagree) to 5 (strongly agree). An average across scores will be calculated with higher scores reflecting greater satisfaction. Possible scores range from 1 to 5.

Timeframe: Change from Baseline to 6 weeks

Participants will report instances of binge eating via items of the Eating Disorders Examination-Questionnaire (EDEQ). Participants report how often they engaged in binge eating over the past 28 days 0 (no days) to 28 (every day). Higher scores represent greater eating pathology.

Participants rate how frequently they experience episodes of mindless behavior via the Mindful Attention Awareness Scale-Adolescent (MAAS-A). The MAAS-A is a 15-item measure of dispositional mindfulness. Participants respond to statements on a scale from 1 (almost always) to 6 (almost never). Items are summed with scores ranging from 15 to 90, with higher scores representing higher levels of mindfulness.

SECONDARY outcome

Timeframe: Change from Baseline to 6 weeks

The Go No Go Task examines inhibitory control via a computerized program. Participants are instructed to press a button when a certain image is shown on the screen (e.g., a green rectangle, a cross). They are instructed not to respond when another image is shown on the screen (e.g., a blue rectangle, an X). Poor inhibitory control is evident by more failures to inhibit responses in the "no go" condition. Reaction time is the processing speed for correct Go trials.

The Go No Go Task examines inhibitory control via a computerized program. Participants are instructed to press a button when a certain image is shown on the screen (e.g., a green rectangle, a cross). They are instructed not to respond when another image is shown on the screen (e.g., a blue rectangle, an X). Poor inhibitory control is evident by more failures to inhibit responses in the "no go" condition. The false alarm rate refers to incorrect No Go trials.
