Considerations for assessing fidelity of the podcast

DomainFactorsExplanation
AdherenceDelivery of the podcast, MP3 player and checklistThe extent to which we delivered the podcast to the parents as planned. Research assistants were to visit participants six times and to play all of the episodes and recaps of previous episodes for the participants. In addition, we gave the participants MP3 players with the podcast, which they could listen to at their convenience. We also gave the participants a checklist summarising the key messages from the podcast.
