Healthy Homes Study: Understanding Radon Testing

The Healthy Homes Study is looking into how to encourage people to test their homes for radon, a gas that can cause lung cancer. This study has two parts. The first part uses focus groups to understand people's thoughts and plans about radon testing. The second part tests different online health messages and reminders to see if they encourage more people to request a free radon test kit. You might be able to join if you are at least 18, live in New Hampshire or Vermont, haven't tested your current home for radon, and live there year-round. The study will measure how many people join, complete surveys, and request a radon test kit.

Study design
This is an interventional study with a planned enrollment of 172 participants. It is a pilot research study with two phases.
What's involved
Participants in the first phase will complete surveys and take part in a 90-minute online focus group. Participants in the second phase will receive different online health messages and potentially reminder messages over two months.
Compensation
Not stated in the trial record.
Follow-up
The study will follow up with participants for up to 18 months to see if they request a home radon test kit.
