- Conditions
- SmokingBinge EatingBehavior
- Registration Number
- NCT03687658
- Lead Sponsor
- Stanford University
- Brief Summary
This study will evaluate the extent to which we can engage and manipulate putative targets within the self-regulation domain within and outside of laboratory settings in samples of smokers and overweight/obese individuals with binge eating disorder. This is the fourth phase of a study that aims to identify putative mechanisms of behavior change to develop an overarching "ontology" of self-regulatory processes.

- Primary Outcome Measures
Name Time Method Binge Eating Episodes - Overeating 28 days Self-reported binge eating episodes is assessed four times daily (morning, early afternoon, late afternoon/evening, and night). A binge eating episode is defined as self-reported overeating and loss of control. Overeating is assessed by the question "Since the last prompt, when you ate most recently, did you overeat?" and is scored as 0 (no) or 1 (yes). Responses provided were averaged across the 28-day period.
Number of Cigarettes Smoked Per Day 28 days Self-reported smoking assessed four times daily (morning, early afternoon, late afternoon/evening, and night). A smoking episode is defined as self-reported smoking of more than zero cigarettes and is assessed by the question "Since the last prompt, how many cigarettes have you smoked?" Participants are asked to input a number into a number field and this was averaged over the 28 day period.
Binge Eating Episodes - Loss of Control 28 days Self-reported binge eating episodes is assessed four times daily (morning, early afternoon, late afternoon/evening, and night). A binge eating episode is defined as self-reported overeating and loss of control. Loss of control is assessed by the question "When you ate most recently, did you lose control over your eating?" and is scored as 0 (No), 1 (Yes). Responses provided were averaged across the 28-day period.
