Kampala is the capital city of Uganda & hosts around 188 slums

Introduction The Good The Bad The Ugly Why ‘cleaning’ interventions targeting users of shared toilets are important?

Research question How can we determine appropriate cleaning behaviour interventions for users of shared toilets in urban slums? Change from bad to good state of shared toilets Cleaning Toilet etiquette

Methodology Cross-sectional survey in 50 randomly selected slums in Kampala (N = 1500, n1019 use shared toilets ). Cleanliness key challenge among users. Linear regression to assess shared toilet users’ cleaning intentions.

Behavioural factors influencing cleaning intention

Determining intentional factors that steer cleaning behaviour FactorsImprovement reserve (Max - Mean) Intervention potential (IR *B) Habit = *0.33 = 0.33 Importance to use clean toilet = *0.20 = 0.14 Cleaning toilet effortful = *0.18 = 0.20 Talking to other toilet users = *0.15 = 0.23 Disgust to use dirty toilet = *0.12 = 0.04 Ease to keep toilet clean = *0.117 = 0.39 Perceived toilet cleanliness by respondents = *0.079 = 0.12 Process (Source: Mosler et al., A guide for behaviour change), Eawag  Look at factors frequencies and means  Determine intervention potential by analysing strength of improvement reserve and impact of each factor on cleaning intention

Intervention development Behavior change technique FactorsMeasure of cleaning behaviour NormsNormative -Personal norm (importance to use clean toilet) -Expressed demand (Talking to other toilet users) -Anticipated regret -Highlighting norms Infrastructural, skill and ability - Self-efficacy (ease to keep toilet clean) and (Cleaning effortful) - Reattribution of past successes and failures -Guided practice towards good toilet use (children) -Facilitating resources (availability of cleaning items) Mosler et al., 2012
