Hypothesis
Does a decision aid for prenatal testing of fetal abnormalities improve women's informed decision-making compared to a pamphlet?
Conclusion
The study aims to determine if a decision aid can enhance informed decision-making and reduce decisional conflict among women considering prenatal testing.
Supporting Evidence
- Decision aids can improve knowledge and reduce decisional conflict in health-related decisions.
- Women often find prenatal testing information difficult to understand.
- The study aims to provide clearer information to help women make informed choices.
Takeaway
This study is trying to see if a special guide helps pregnant women make better choices about tests for baby health compared to just reading a pamphlet.
Methodology
A cluster randomised controlled trial with 50 GPs providing either a decision aid or pamphlet to women, measuring informed choice and decisional conflict.
Potential Biases
Selection bias may occur due to the nature of cluster randomisation and the recruitment process.
Limitations
The study may face challenges with participant attrition and the potential for contamination between groups.
Participant Demographics
Pregnant women aged 18 years or older, attending participating GPs, with a focus on those less than 12 weeks gestation.
