The review shows that that behaviour change techniques can operate alongside each other, so there is a need to explore the dynamics and interactions between them within the behaviourchange model, and to extend it, e.g. by including emotional drivers of change, personality dynamics, and changes in social environment.

The authors recommend a modified behaviour change framework, which reflects the four overarching categories of influence that determine behaviour: individual, social, structural, and locational. The framework also shows the relationships among these categories, recognising that the process of behaviour change is dynamic, and interacts at multiple levels.

The framework will be further developed and tested through the SEI Initiative on Behaviour and Choice.
