| Scientific title | |
| Acronym | FAB |
| Serial number at source | N/A |
| Study hypothesis |
Aim: To quantify the effect of measurement and feedback on physical activity behaviour
Measurement objectives: 1. Self awareness of physical activity levels 2. Effect of measurement on awareness 3. Effect of feedback on awareness and intentions 4. Effect of feedback on behaviour 5. Level of false reassurance |
| Ethics approval | Full ethical approval received from Cambridgshire 2 Research Ethics Committee on 03/05/2007 (ref: 07/Q0108/79) |

| Interventions |
The FAB Study has been set up as a nested cohort study within the Fenland Study, but with a very different purpose, and with separate ethical approval.
Volunteers in the Fenland Study have agreed to undergo oral glucose tolerance test and precise measurement of body anthropometry, body composition and physical activity over a one-week period (using individually calibrated Actihearts which measure heart rate and movement). Those who volunteer for FAB are randomly allocated to one of four groups: Group 1: Control group - no feedback Group 2: Physical activity feedback type A - Physical Activity Level (PAL) Group 3: Physical activity feedback type B - PAL + daily heart rate and movement printouts Group 4: Physical activity feedback type C - PAL + daily heart rate and movement printouts + goal setting and modelling information |
| Primary outcome measure(s) | Objectively measured physical activity over 1 week (one month post-feedback), using a combined heart rate and movement sensor. |
| Secondary outcome measure(s) |
1. Self-reported physical activity - RPAQ (baseline, and 1 month after feedback)
2. Self-rated physical activity (baseline, immediately after feedback, and 1 month after feedback) 3. Worry about own physical activity (baseline, immediately after feedback, and 1 month after feedback) 4. Physical activity outcome expectations (baseline, immediately after feedback, and 1 month after feedback) 5. Physical activity self-efficacy (baseline, immediately after feedback, and 1 month after feedback) 6. Intention to change physical activity (baseline, immediately after feedback, and 1 month after feedback) 7. Time orientation (baseline only) |
