Emerging adulthood is a critical period with increased risk of acute and chronic health complications, psychological problems, and psychosocial issues for emerging adults with type 1 diabetes (T1D) [1]. Emerging adults with T1D undergo several transitions as they move from childhood to adulthood. In addition to the developmental milestones they are expected to achieve, they must transfer to adult care and take up self-management of their chronic condition, which can be challenging [1]. While self-management constraints can be difficult to adhere to at any age, glycaemic control is poorest during emerging adulthood.
