Randomization
BLIND
Participants were assigned into the intervention and control groups in a ratio of 1: 1 using block randomization (stratified based on first or second childbirth) using Random Allocation Software (RAS) with a block size of 4 and 6. The type of intervention was written on paper and placed in opaque envelopes numbered consecutively for the allocation concealment. The envelopes were opened by a non-involved person in the sampling process (expert of health center) in the order in which the participants entered the study. The participants were not aware of their group and due to the nature of the intervention (counseling), this was a single blind study.
