The Design of an Ontology-Driven mHealth Behaviour Change Ecosystem to Increase Physical Activity in Adults

Abstract

AbstractThe global pandemic and the resulting lock-downs have indicated the importance of regular physical activity for both mental and physical wellness. Many mHealth applications to increase physical activity exist, they however continue to fail to achieve their objective. The need arises for a more theoretically-grounded approach that considers the dynamic nature of the individual. To create a system that is context-aware and personalised, an interdisciplinary approach is needed and regular input of stakeholders and end-users is of the essence. This expert knowledge is captured into an ontology, centred on the Health Action Process (HAPA) model for behaviour change. This paper describes the requirements for the design of such a mobile health Behaviour Change System for increased physical activity in adults and emphasises the need for personalisation on the level of the user, action and coping planning and motivational level.KeywordsKnowledge representationOntologyHealth careUser-centricPersonalisationDecision support systemHuman-computer interactionHealth behaviour change
