We help you to elaborate a quantitative questionnaire about your interventions and about the behavioral factors of the RANAS model. You can then compare households that received your intervention with those that did not or received only part of it. This analysis reveals how effective your interventions have been in changing behavior. You can also see whether you changed the most relevant behavioral factors. If not, we can help you design new interventions which target the behavioral factors that have not yet been changed and so improve your interventions substantially.
