Evaluation of Report-Back Strategies for Long-term and Short-term Exposure Information in Rural Tribal Populations
A study testing Messenger 1, Messenger 2 and Format 1 in people with Behavior Change, run by University of Utah.
Trial summary
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). Read more about this study

About this study
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.

Receives: Behavioral: Messenger 1; Behavioral: Messenger 2; Behavioral: Format 1; Behavioral: Format 2 |
| Delayed Exposure Data | Experimental | 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Exposure Reduction Behaviors
This will be collected using a questionnaire with a likert scale from 1 (not at all) to 10 (a lot) of how often certain exposure-reduction behaviors are performed.
Measured: 3 months after report-back

How can a doctor refer a patient or contact the research team?
Contact Darrah K Sleeth, PhD (801-585-3587, darrah.sleeth@hsc.utah.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Exposure Reduction Behaviors (time frame: 3 months after report-back). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Dec 2025.
