  1. aMixed effects or generalized linear mixed models were used to adjust for the clustering effects of churches and to account for repeated measures over M2 and M3. If the time by condition interaction term was not significant, the term was dropped and the condition main effect was tested. All analyses were adjusted for the baseline measure of the outcome, age, marital status, employment and education
  2. bNegative binomial error distribution. Results are shown in logged units
  3. cBinomial error distribution (Logistic model)
