Design outcomes
Primary
| Measure | Time frame |
|---|---|
| 1. The feasibility of conducting a large scale RCT of attention trainings in overweight/obese patients by assessing recruitment, attendance, and retention rates. An acceptability and credibility questionnaire will be administered at post-assessment (i.e., week 8) 2. The quality, completeness, and variability of the outcome measures, determined using descriptive statistical analyses and graphical methods | — |
Secondary
| Measure | Time frame |
|---|---|
| Weight, eating behaviour and cognition before and after trainings. Assessment of these outcome measures will include different self-report questionnaires: 1. Hunger, craving, mood, stress and anxiety levels, measured using the Visual Analogue Scale (VAS) 2. Eating behaviour and awareness, assessed using the Food Craving Questionnaire – Trait version (FCQ-T), the Eating Disorders Examination Questionnaire (EDEQ), the Power of Food scale, the Mindful Eating Questionnaire (MEQ) and Mindful Awareness and Attention Scale (MAAS) 3. General psychopathology measured using the Depression, Anxiety and Stress Scale (DASS-21) and the State and Trait Anxiety Inventory (STAI) 4. Quality of diet and calorie intake assessed using 24h dietary recall questionnaire 5. BMI and body composition calculated by taking height and weight on the day of the assessment using a bioelectrical impedance scale 6. Different components of attention (i.e. alerting, orienting and executive attention) assessed by the food-Attention Network Task (Food-ANT) 7. Attention bias for food, measured by a dot-probe task while recording eye movements 8. Preference of low vs high-calorie food items, assessed using the food-choice task 9. State levels of cue-elicited food cravings, assessed using the Food Challenge Task 10. Food intake measured by the Bogus Taste Test, where participants will be asked to rate different kinds of highly palatable food in terms of their visual attractiveness, smell and taste and will be told that they should try as much of the offered items as they like. Food consumption will be determined by weighing remaining food.? All of these measures will be taken both at baseline assessment and post-assessment (8 weeks) with the exception of the EDEQ and the Power of Food Scale, which will also be completed by participa | — |
