 In Phase 2 we will evaluate the impact of the intervention on handwashing behaviour in the target population, i.e. handwashing at specified times in school children and their mothers. Hygiene behaviour will be measured by two methods: 1 sticker diary measured by revisiting the Phase 1 villages and households; 2 Direct structured observation of handwashing. For the structured observation study we will recruit households from 12 control and 12 intervention villages that are different from the phase 1 villages. We will further evaluate the early effect of the intervention on knowledge of intervention content, attitudes and motivations related to hygiene behaviour and handwashing in school children and their parents. The results of phase 2 will tell us whether the intervention changed the target behaviours as a basis for achieving any health impact. Based on the results of Phase 2 we will make the following decisions for Phase 3 in collaboration with the co-funder CIFF: 1 if Phase 2 indicates a marked behaviour change with the potential to impact on health, we will proceed with the measurement of the main health outcomes in all study villages. 2 If there is no major behaviour change potentially impacting on health, we will focus on the process documentation, qualitative research and with the aim of obtaining knowledge for improving the current campaign and increase our learning from the programme.
