Noninvasive prenatal screening based on cell-free DNA sequencing was first established in 1997 [Thailand is a developing country with a national policy for prenatal screening and diagnosis [Reports from developed countries have found that various tools in prenatal genetic counseling, such as educational apps and videos as well as low literacy decision aids, can improve the knowledge of pregnant women who undergo cell-free DNA screening [Therefore, the primary aim of this study was to compare the effectiveness of an animated educational video combined with traditional counseling versus traditional counseling alone in changing pregnant women’s knowledge of cell-free DNA screening. The secondary aims were to assess attitudes toward positive screening test, levels of satisfaction with counseling, and rates of acceptance of cell-free DNA screening after counseling.
