FOODS: Food shOppers' sOcial meDia Study

Study Overview
=================
Brief Summary
-----------------
This study aims to assess the effects of a new approach to food labelling called physical activity calorie equivalent (PACE) labelling. PACE food labelling provides the public with information about how many minutes (or miles/kilometres) of physical activity (e.g. walking or running) are equivalent to the calories contained in foods.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in eating behaviour of discretionary foods at 13 weeks | Eating behaviour of discretionary foods will be assessed by a modified version of Online Food Frequency Questionnaire (eNutri FFQ), designed to measure habitual food intake. Participants will record frequencies of discretionary food and drink items eaten during the last month (e.g. 1/week or 1/day). | Pre-baseline (one time point prior to randomisation) and post-intervention (one time point after week 13) | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Cognitive restraint of eating | A modified version (R18) of the Three-Factor Eating Questionnaire (TFEQ) will be used to measure cognitive restraint. | Pre-baseline (one time point prior to randomisation) and post-intervention (one time point after week 13) | 
| Physical activity | Self-reported physical activity behaviour will be assessed using the 7-day International Physical Activity Questionnaire (IPAQ) | Pre-baseline (one time point prior to randomisation) and post-intervention (one time point after week 13) | 
| Body weight | Weight will be self-reported via participants own weighing scales. Participants will electronically send via email photograph evidence of readings of their fasted morning weight from weighing scales, following standardised instructions. | Pre-baseline (one time point prior to randomisation), mid-intervention (week 7) and post-intervention (one time point after week 13) |
