BLINDNESS
After an initial agreement to participate in the study, an invitation was sent as a message to potential participants’ mobile phones using the WhatsApp platform, which allowed for communication between the participants and the research team and sending or receipt of the consent, intervention/CG flyer, and the online questionnaires.The participants were randomly assigned to either the SG or the CG by the research team. The simple randomization process consisted of previously shuffled sealed envelopes with numbers with an equal allocation ratio placed in a bowl. Each participant randomly chose an envelope number virtually, giving them an equal chance of being placed in either group. The sealed envelopes were opaque and numbered in a sequence to ensure allocation concealment. To achieve blindness, the participants were told that the study’s goal was to examine two ways of information delivery meant to improve oral health knowledge among pregnant women. The research team used WhatsApp to give the participants a link that contained the study consent form and the baseline questionnaire (T1). Then, the participants in the SG received a barcode to add the intervention’s Snapchat account. The participants were assessed three times: T1 prior to the intervention, T2 immediately following the intervention (at the same day), and T3 for follow-up 1 month later to assess their retention of the information.
