Background: Lifestyle programmes require a structured approach to be effective. Maintaining fidelity of coach-based interventions is challenging. Mobile devices may assist by supporting the use of an algorithm based approach.
Aims: To describe the development and challenges associated with a mobile technology approach to supporting a coach-based lifestyle programme for the prevention of gestational diabetes mellitus (GDM) in pregnancy.
Methods: Narrative approach to system design, with a survey of 12 lifestyle coaches involved in the pan-European multicentre DALI (Randomised controlled trial for the prevention of gestational diabetes mellitus (GDM) with vitamin D And Lifestyle Intervention) study.
Results: A mobile device based programme was associated with more technical issues than a web-based approach, particularly in relation to upgrades to improve usability and utility. Even after multiple upgrades, a paper approach was preferred by some coaches, and by most for aspects of the intervention that required greater coach-participant interaction (eg goal setting). Coaches generally preferred the mobile device approach for obtaining pre-existing data, structured data entry and for intervention prompts.
Conclusion: Mobile technology can facilitate coach-delivered lifestyle interventions. However, more work is required to minimise intrusion into the behavioural intervention.
