The Risks, Attitudes, Norms, Abilities, and Self-regulation (RANAS) approach to systematic behavior change is an established method for designing and evaluating behavior change strategies that target and change the factors influencing a specific behavior in a specific population. In brief, it is an easily applied method for measuring behavioral factors, assessing their influence on behavior, designing tailored strategies that change behavior, and measuring the effectiveness of these.
The aim of this manual is to give practitioners a tool to help them when designing an effective behavior change campaign. The methodology is explained step by step, all necessary skills and other requirements are described, and possible pitfalls are noted.
