Hello All,

In many programmes (not just Nutrition, e.g. hygiene promotion) where a behavioural change is sought I have often seen indicators such as: x% of targeted caregivers can recall at least 3 messages...

Is there an actual evidence base for this i.e. how was the number 3 arrived at.
Any studies I could be referred to on indicators for behavioural change would be very helpful.

Many thanks,
Hisham
