About

The goal of this study is to evaluate different ways to provide feedback about environmental sampling results to participants. Specifically, the study 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 the 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.

Real-Time Exposure Data

Experimental group

Description:

Participants in this arm will get their data reported-back in real-time. There will be a total of 4 different strategies tested based on a combination of two (2) messengers and two (2) formats tested.

Treatment:

Behavioral: Format 1

Behavioral: Messenger 2

Behavioral: Messenger 1

Behavioral: Format 2

Delayed Exposure Data

Experimental group

Description:

Participants in this arm will get their data reported-back only after all exposure data are collected (i.e., delayed approximately 2 months). There will be a total of 4 different strategies tested based on a combination of two (2) messengers and two (2) formats tested.

Treatment:

Behavioral: Format 1

Behavioral: Messenger 2

Behavioral: Messenger 1

Behavioral: Format 2
