About this page

Behavioural science is a multidisciplinary field that combines psychology, economics, and other social sciences such as anthropology or sociology. Behaviour change frameworks are essential for applied behavioural science. They are not actual representations of behaviour but rather intentional simplifications of complex phenomena, which makes them comprehensible and actionable in the public and private domains. Behaviour can be conceptualised and defined in many ways and over past decades, many different models have tried to capture influences on behaviour. This growing number of models can be confusing to navigate, even for experienced practitioners. This guide is designed to make it easier.

In this article, I share 8 different behavioural science models, including: COM-B, Self Determination Theory, B=MAT and the Behavioural Drivers Model. I have selected these models because they are important in the literature and have been directly applied in the field. However, this is an ongoing project, so expect more in the future.
