Objective:
To develop and evaluate a decision aid designed to prepare patients of advanced maternal age for counseling about prenatal diagnostic testing.
Setting:
A regional genetics center.
Design:
A before/after study.
Interventions:
Participants used an audioguided workbook to learn about options and outcomes and to clarify personal risks, values, questions, and predispositions.
Subjects:
21 women of advanced maternal age and 17 spouses.
Main Outcome Measures:
Knowledge of prenatal testing alternatives, decisional conflict, level of anxiety, and acceptability of the decision aid.
Results:
After using the decision aid, participants had significantly reduced decisional conflict (uncertainty) and a significant increase in knowledge. There was no effect on state or trait anxiety. More than three-quarters of participants were satisfied with the length, clarity, balance, and acceptability of the decision aid.
Conclusions:
The decision aid shows promise as a useful aid for preparing couples for counseling.
