 Our primary analyses will involve testing of each of these hypotheses under the intent-to-treat ITT principle see section on missing data below using Generalized Linear Mixed Models GLMM that will account for the correlation induced by the clustering of parents and children within childcare centers. Each GLMM see below will include a random intercept for childcare centers b0 and fixed effects for the baseline value of the primary outcome β1 and the intervention β2 to test if the differences in mean changes in primary outcomes is zero, where β0 is the fixed intercept, and e is error.
