Just-in-time adaptive intervention (JITAI) to Sit Less and Move More: protocol for a micro-randomised trial (MRT) in people with type 2 diabetes
ABSTRACT
Background:
Reducing sedentary behaviour (SB) and increasing physical activity (PA) in people with type 2 diabetes (T2D) is associated with various positive health benefits. Just-in-time Adaptive Interventions (JITAIs) offer potential to target both these behaviours via more contextually aware, tailored, and personalised support. We have developed a JITAI intervention to promote sitting less and moving more in people with T2D.
Objective:
This paper presents the study protocol for a micro-randomised trial (MRT) to investigate whether motivational messages are effective in reducing time spent sitting in people with T2D, and to determine what behaviour change techniques are effective and in which context (e.g., location, etc.).
Methods:
A six-week MRT design will be used. Twenty-two adults with T2D will be recruited. The intervention aims to reduce sitting time and increase time spent standing and walking, and comprises a mobile app (iMove), and a bespoke activity sensor (SORD), a messaging system and a secured database. Dependant on the randomisation sequence, participants will potentially receive motivational messages five times a day.
Results:
Study recruitment and participation was started on April 2022.
Conclusions:
The current study will inform the optimisation of digital behaviour change interventions to support people with T2D sit less and move more to increase daily physical activity. This study will generate new evidence about the immediate effectiveness of SB interventions, their active ingredients and associated factors.
