I think your point is very well taken! Perhaps the issue is that we're still using traditional WASH models to assess CLTS projects rather than using public health models for behavioural change? If we were to shift project modelling to something like the transtheoretical model, which allocates a range of time for each phase of behavioural change and allows for cycles of relapses, that may change the way that CLTS is perceived and administrated. I don't think that the transtheoretical model for behavioural change is necessarily the most effective way to activate WASH behaviours, but I do think that the way it describes the process of behavioural change can be instructive for CLTS.
