A three dimension virtual experience of delivery: childbirth and parenthood education's benefits and complementarity in the use of a new audiovisual serious device. Background: After working on the development of a new device in order to evaluate childbirth and parenthood education (PNP), the medical team needed to check women's knowledge about delivery to make sure the device was necessary. Methods: A comparative study was led on 89 primiparous who had delivered at the maternity hospital Port-Royal. Results: women with PNP are more aware of labor and delivery, know when they must come to the maternity, show less anxiety and a better pain management. 93% of women went online to find pregnancy related information. These are perceived reliable, but insufficient, not really reassuring, even an anxiety source sometimes. Women judged the serious game's idea as serious, interesting, useful and necessary. Conclusion: PNP is beneficial and efficient. The audiovisual device created seems to be a good way to promote and develop this health program.
