We propose to determine the impact of providing complete information about all prenatal tests for chromosomal disorders to women of all ages and allowing them to make informed choices regarding which tests, if any, to undergo. Specifically, we plan to update a validated prenatal testing decision-assisting tool (""""""""PT Tool"""""""") to incorporate all new screening options and make it more accessible to a lower literacy population. We then will conduct a randomized controlled trial comparing the effect of an """"""""informed free choice"""""""" approach to testing, consisting of providing information regarding and access to all prenatal testing options, to that of usual care among a racially/ethnically, socioeconomically and age-diverse population of pregnant women. The primary goal is to generate evidence needed to determine whether clinicians should consider an alternative to the current practice of using only risk-based thresholds for invasive testing and adopt a strategy that would enable all women to make informed choices that are reflective of their own values and preferences. A second goal is to expand PT Tool to include new screening tests and modify it for use by lower literacy women.
Specific aims are to: 1) determine which testing strategies are selected by women who receive complete information on all testing options and have all the options available to them compared to women receiving usual care; 2) update both the English- and Spanish-language versions of PT Tool to include information on new screening options and modify them for use by lower literacy women; 3) assess the impact of receiving complete information on and access to all testing options and having all options available on knowledge, risk comprehension, and decisional conflict compared to usual care; 4) evaluate the cost effectiveness of an """"""""informed free choice"""""""" approach to providing prenatal testing services compared to usual care. In short, this study will generate a useful decision-assisting tool and provide information for use in designing cost-effective testing programs that allow for variation in preferences. ? ?
