Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The Australian Diabetes Body Project (ADBP) is a virtual, group-oriented, co-led (clinician and peer) ED prevention program based on cognitive dissonance theory.
The ADBP will involve six, one-hour, virtual sessions held over six consecutive weeks.
The group sessions will have two facilitators; a clinician (psychologist) and a peer-educator with T1D. Groups will include up to 8 participants, and will be held at various times throughout the year. In between the sessions, participants will complete homework exercises to be discussed at the following session.The topics for the six sessions are as follows:
1. Define the ideal and explore its origin
2. Examine the costs of pursuing this ideal
3. Explore ways to resist pressures to be thin
4. Discuss how to challenge our personal body image concerns
5. Learn new ways to talk more positively about our bodies.
6. Discuss how to promote a positive relationship with diabetes and insulin.
Adherence to the group sessions will be monitored by the group facilitators. Participants who fail to attend group sessions will be followed up by a facilitator or research team member.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation using sealed envelopes
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomly assigned 1:1 to the virtual ADBP or the active control group (educational videos) via a random number sequence provided by an independent statistician. Random permuted block randomisation with variable block sizes will be used to minimise chances of imbalance while maintaining unpredictability in the assignment sequence.
