The RANAS Model


The Risks, Attitudes, Norms, Abilities and Self-regulation (RANAS) approach to systematic behaviour change is an established method for designing and evaluating behavior change strategies that target and change the factors influencing a specific behaviour in a specific population. In brief, it is an easily applied method for measuring behavioural factors, assessing their influence on behaviour, designing tailored strategies that change behaviour, and measuring the effectiveness of these.
