The effects of ethnicity, education and an informational video on pregnant women's knowledge and decisions about a prenatal diagnostic screening test

Prenatal screening for genetic disease and developmental disabilities is rapidly becoming a routine part of the management of low-risk pregnancies. Yet research on how to best inform pregnant women about these tests and their special ethical entailments remains sparse. We asked 130 low-risk pregnant women of diverse ethnic and social class backgrounds a series of questions about a prenatal test they had been offered within the previous 3 months. All had been given an informational booklet about the test at the time it was offered; about half also saw a video. We found that neither group of women retained much of the information they had received about the prenatal screening but that those who saw the video remembered more. Information-retention also varied significantly by ethnicity and level of education.
