Designing for Sustained Motivation: A Review of Self-Determination Theory in Behaviour Change Technologies
We consider how self-determination theory (SDT), a metatheory of human motivation and wellbeing, can help explain why such technologies fail, and how they may better help users internalise the motivation behind their goals and make enduring changes in their behaviour. By systematically reviewing 15 papers in the ACM Digital Library that apply SDT to the design of behaviour change technologies (BCTs), we evaluate suggestions in current work and highlight future opportunities.
