The core of the Risks, Attitudes, Norms, Abilities, and Self-regulation (RANAS) approach forms the RANAS model. The RANAS model is a holistic theoretical model of human behaviour change, developed based on scientific evidence. The model has four components: behavioural factors that are grouped into five blocks, behaviour change techniques (BCTs) that correspond to the behavioural factors, behavioural outcomes, and contextual factors. The RANAS model is the theory of change of the RANAS approach: The BCTs change the specific behavioural factors that steer the behaviour and this change in behavioural factors leads to a change in behaviour.
