Binge eating behaviour Mental and Behavioural Disorders
Conditions
Interventions
Following our previous procedures showing successful reactivation of ingrained associative drinking memories in heavy drinkers, we aim to reactivate maladaptive binge-eating memories through brief cue
N = 30), 2) Non-binge memory reactivation + CC (NR+CC
3) Binge memory reactivation+ sham CC (BMR + sham CC
N= 30).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Eating behaviour measured by: 1. Binge frequency/food diary: Daily food consumption will be logged via an online diet app (MyFitnessPal), using anonymised login codes. On each day, participants will also log subjective binges. From these diaries, experimenters will extract frequency of subjective binges and consumption information (caloric volume of binge foods and non-binge foods consumed). The outcomes will thus be 1) frequency of subjective binge episodes in the pre-intervention (baseline) period, post-intervention (test) period and follow-up 2) average (mean, or median if high skew is present) corresponding macronutrient intake over these same periods. This outcome is assessed on Day 1, Day 14 and the first follow up (28 days after Day 1) 2. Eating Disorders Examination-Questionnaire (EDE-Q) This is a questionnaire version of the Eating Disorders Examination (EDE) and is used to assess disordered eating. This is assessed on Day 1 and 14 and at follow up at 28 days, 3 months, 6 months and 9 months. 3. Binge Eating Scale (BES) This is a questionnaire-based measure of specific binge eating symptomatology severity. This is assessed on Day 1 and 14 and at follow up at 28 days, 3 months, 6 months and 9 months. 4. Food Craving Questionnaire State/Trait (FCQ-T/FCQ-S): This is a measure of desire to eat one or more specific foods. The trait version assesses generally experienced food craving and the state form momentary craving. The state version will be used to assess momentary craving evoked by exposure to binge food images and in-vivo high-palatability food at baseline (pre-intervention) and test (post-intervention). FCQ-T assessed on Day 1 and 14 and at follow up at 28 days, 3 months, 6 months and 9 months. FCQ-S is assessed on Day 1, 2 (48-72 hr after Day 1) and Day 14. | — |

| These measures are potentially important covariate or cofounding factors that we wish to assess for similarity between groups at baseline, but which are not outcomes for study. No specific predictions are made about changes in these measures. 1. Height/weight and BMI, resting heart rate, blood pressure, and blood glucose are assessed in-lab at Day 1 (baseline), Day 2 (intervention day) and at Day ~14 post-intervention (test) using high-accuracy scales, an Omron heart rate/blood pressure cuff, and through finger-prick glucose oxidase with an SDCheck monitor, respectively. 2. Basic information, Family History of Eating Disorders and Typical Binge Foods List are recorded pre-intervention on Day 1 (baseline). 3. Depression via the Beck Depression Inventory (BDI), Trait Anxiety via the Spielberger Trait Anxiety Index, Trait Impulsivity via the Barratt Impulsiveness Scale (BIS), Trait Behavioural Inhibition and Activation via the BIS/BAS scale, temporal discounting via the Kirby Delay-Discounting Task (DDT), tolerance for distress via the Distress Tolerance Scale, and disgust via the Disgust Propensity and Sensitivity Scale-Revised, are assessed pre-intervention on Day 1 (baseline) and post-intervention on Day ~14 (test). 4. Food Addiction Symptomatology are assessed using the Yale Food Addiction Scale (Y-FAS), Three Factor Eating Questionnaire-revised (TFEQ-r), and the Power of Food Scale (PFS), at pre-intervention on Day 1 (baseline) period, post-intervention Day ~14 (test) period. 5. Calorie consumption and satiety are assessed via a Timeline Follow-Back (TLFB) and Hunger Scale, respectively, at pre-intervention on Day 1 (baseline) and post-intervention on Day ~14 (test). 6. Anxiety via a visual analogue scale, and affect via the Positive and Negative Affect Scale are assessed on Day 2 (intervention), pre and post intervention. 7. The YFAS, BES, FCQT, PFS, TF | — |
