Background

In the BCT Taxonomy v1 (BCTTv1)[1] there are 93 BCTs grouped into 16 domains. For example, the BCT “self-monitoring of behaviour” is in the domain “feedback and monitoring”. Each technique has a specific definition that distinguishes it from the other techniques. The BCTTv1 has increased consistency in the language used to describe the ‘active ingredients’ of interventions to change behaviour.
