Brief Summary

The goal of this study is to evaluate different ways to provide feedback about environmental sampling results to participants. Specifically, we will look at exposures with long-term risk (radon) and short-term risk (indoor particulate matter, PM2.5). The hypothesis is that providing feedback in real-time will result in participants engaging in more activities to try to reduce their exposure. One of our main questions of interest is: How does the information messenger impact the effectiveness of report-back strategies in rural, tribal populations?

Participants will have radon and PM2.5 measurement equipment installed at their home and will answer questions about any actions they took to reduce exposure. Previously developed approaches to reporting back those exposures will be used to test which feedback method results in more actions to reduce exposure.

Primary Outcome Measures

Name	Time	Method
Exposure Reduction Behaviors	12 months after report-back	This will be collected using a questionnaire with a likert scale of how often certain exposure-reduction behaviors are performed.
