Abstract
Objectives To describe women's preferences for prenatal testing outcomes and to explore their association with sociodemographic characteristics and attitudes. Methods We conducted a cross-sectional study of 584 racially/ethnically and socioeconomically diverse pregnant women aged 16 to 47 years recruited from 23 San Francisco Bay Area practices. We assessed preferences for 12 potential prenatal testing outcomes using the time trade-off metric for all outcomes and the standard gamble metric for two outcomes. Preferences were calculated on a scale of 0 (death) to 1 (perfect health). Participants also completed a sociodemographic and attitude survey. Results Highest preference scores were assigned to outcomes resulting in the birth of a chromosomally normal infant (mean = 0.91–0.93; median = 0.99–1.00). Lower scores were obtained for outcomes involving pregnancy loss (mean = 0.69–0.87; median = 0.76–0.92), which were correlated with attitudes regarding miscarriage, pregnancy termination, and Down syndrome. The lowest scores were assigned to Down syndrome–affected births (mean = 0.67–0.69; median = 0.73–0.75), which also were correlated with attitudes toward Down syndrome. We did not find a statistically significant relationship between participants' preference scores and age. Conclusion Preferences for prenatal testing outcomes vary according to the pregnant women's underlying attitudes about pregnancy loss and Down syndrome, and not according to her age. Current age/risk-based guidelines should account for individual variation in patient preferences. Copyright © 2004 John Wiley & Sons, Ltd.
