Who could benefit from this research
✓Could help
Individuals considering metoidioplasty or phalloplasty who want structured information to guide their decisions.
✕Less likely to help
People not considering MaPS or those already certain about their choice may be less affected by the tool.
What this research studies
This project creates and tests an easy-to-use online tool that explains the different surgical options for gender-affirming genital surgeries and how they compare to not having surgery. It builds on earlier work with patients and surgeons to ensure the content is understandable for people with different health literacy levels. The study will measure how usable and acceptable the decision aid is and gather early signals that it may improve decision quality and reduce regret. It emphasizes collaboration with patients, providers, and diverse communities to Coproduce reliable information.
Why it matters
Potential benefit: If successful, patients could make better-informed decisions with less regret about MaPS surgeries.
How similar studies have gone: Prior work showed promise with a similar decision aid approach, but this MaPS tool is specifically tailored to these surgeries.
