Table 1 Behaviour change techniques as implemented within Juicy June
From: Juicy June: a mass-participation snack-swap challenge—results from a mixed methods feasibility study
Behaviour change technique | Practical strategy |
|---|---|
- 1.1 Goal setting (behaviour)/1.4 Action planning | - Participants prompted to decide specifically what snack to swap with what healthier alternative prior to the start. |
- 2.2 Feedback on behaviour | - Dietary analysis provided following baseline measures in the format of a graph depicting personal intake alongside government guidelines using traffic light colour coding. |
- 2.3. Self-monitoring of behaviour | - Hard-copies of self-monitoring sheets provided (to record each day snack-swap successfully achieved). Suggested to participants that this be attached to the fridge or other highly visible place. |
- 4.1 Instruction on how to do a behaviour | - Clear information of what is intended by a ‘snack swap’, and what constitutes a healthy snack. Provided via email. |
- 3.3 Non-specific social support | - General encouragement provided in standardised materials (including reminders to self-monitor). Weekly contact asking how participants had got on. - Enrolment on a Facebook group; regular encouraging posts uploaded onto the Facebook page every 2 days. |
- 5.1 Information about health consequences | - Provided in study materials provided before and during the intervention |
- 7.1. Prompts/cues | - Provision of a hard-copy calendar; weekly texts to cue preparation for snack swapping (e.g. shopping for target snacks) |
- 7.2 Reduce prompts/cues | - Participants asked not to stock unhealthy snacks at home/in the workplace |
- Promote autonomy support | - Study materials presented using non-controlling language (i.e. ‘you can, you may choose to’ rather than ‘you should, you must’); promotion of choice (in what aspects of diet to substitute); presentation of a rationale for change; provision of structure for behaviour change through outlining a simple snack-swap. |
