New resource for the behaviour change community!
We have now launched the Theories and Techniques of Behaviour Change Heat Map tool - our interactive resource, which provides easy access to information about the links between behaviour change techniques and their mechanisms of action.
- To identify and integrate hypothesised links between (i) BCTs and MoAs and (ii) BCTs and behavioural theories.
- To generate an online, freely available, searchable resource to support theory-based intervention development and evaluation.
The effectiveness of behaviour change interventions depends on good understanding of the links between behaviour change techniques (BCTs) and their mechanisms of action (MoAs) i.e. the processes through which they affect behaviour. Considerable progress has been made in developing a method for specifying BCTs. The aim of this research is to develop and test a methodology for linking BCTs to their MoAs.
Study 1: To synthesise evidence of links between 93 BCTs (from the 93-item BCT taxonomy, BCTTv1) and their MoAs, data will be extracted from published intervention papers. The frequency, explicitness and precision with which each BCT is linked by authors to each MoA will be reported.
Study 2: Behaviour change experts will identify links between BCTs and MoAs in a formal consensus development study. They will be asked about 26 MoAs, 12 frequently occurring in theories of behaviour change and 14 from the Theoretical Domains Framework. The data from Studies 1 and 2 will generate matrices of links between BCTs and mechanisms.
Study 3: Agreement between the matrices from Studies 1 and 2 will be evaluated. A new group of experts will be consulted to discuss and resolve discrepancies. An integrated matrix of BCT-MoA links, annotated to indicate strength of evidence, will be generated.
Study 4: To identify whether groups of co-occurring BCTs can be linked to theories, groups of two or more BCTs that work together (i.e. BCT ‘clusters’) will be identified from the Study 1 literature corpus. A consensus exercise will be used to rate strength of links between BCT clusters and theories, generating a matrix of links between BCT clusters and theories.
The development of a formal methodology for linking BCTs to MoAs has the potential to make a substantial contribution to the development and evaluation of behaviour change interventions. This research is a step towards developing an ‘ontology’ of behaviour change that specifies the relations between BCTs, theoretical mechanisms, modes of delivery, population, setting and type of behaviour (see https://www.humanbehaviourchange.org/).
An ontology of Mechanisms of Actions is currently being developed as part of the development of a formal Ontology of Behaviour Change Interventions (see https://www.humanbehaviourchange.org/), which will allow us to better evaluate, report and replicate behaviour change interventions.
