Centre for Behaviour Change

The Behaviour Change Technique Taxonomy Version 1 (BCTTv1) is very widely used for characterising the content of behaviour change interventions in a systematic way that forms the basis for scientific study. The taxonomy has been extended, improved and developed in a way that links techniques with other aspects of the intervention such as its delivery, target behaviour, setting, population and mechanisms of action. This allows for much fuller description than has been possible to date and more complex questions to be answered, such as variants of the “Big Question ”When it comes to behaviour change interventions: What works, compared with what, for what behaviours, how well, for how long, with whom, in what setting, and why?”

Time: 10am-4pm, with 30 minutes for lunch and 15-minute breaks in the morning and afternoon.
