Attitudes toward prenatal screening for chromosomal abnormalities: A focus group study.

Background: While discrete choice experiments (DCEs) are well established methods to ascertain patient preferences, there is limited literature describing use of qualitative methods in DCE design.

Aim: This article provides a case study of the qualitative research process for developing the conceptual attributes for a DCE for prenatal screening and diagnosis.

Methods: Participants were recruited through posters and social media. Four in-depth, semi-structured focus groups with pregnant women and their partners/support people were conducted in Metro Vancouver.

Findings: Our analysis indicates that choosing prenatal screening and diagnosis involves four intertwined decisions: whether to undergo screening and testing, which screening test to take, which diagnostic test to take, and what to do with a positive diagnosis. The factors that are important to women and their partners vary depending on the decision and include: time of diagnosis, information on conditions tested, false positives, cost, the invasiveness of the test, and potential harm to woman and baby.

Discussion: Findings suggest that certain attributes were more salient for screening versus diagnostic tests. Preferences were often shaped by a woman's perceived ability to care for a child with a genetic anomaly, personal risk factors, parity, views on termination, and perceptions on public or private coverage. Participants valued mental well-being and demonstrated a willingness to trade-off on certain attributes in order to minimize stress or anxiety during pregnancy.

Conclusion: Study findings will be used to inform DCE attributes, levels, and choice questions. Findings will be important for policy decisions surrounding prenatal testing.
