What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Radon Risk Messaging MaterialsBehavioural
Newly designed or adapted radon risk messaging materials intended to increase radon awareness and risk perception or prompt radon mitigation.
| Study group | Role | What they receive |
|---|---|---|
| Treatment Group | Experimental | Newly designed or adapted radon risk messaging materials. Receives: Behavioral: Radon Risk Messaging Materials |
| Comparison Group | Active comparator | Generic or standard radon materials from the Environmental Protection Agency (EPA) or Centers for Disease Control (CDC). Receives: Behavioral: Radon Risk Messaging Materials |
| Waitlist Control | No intervention | No radon messaging materials during the trial. Participants may receive information about radon after the trial. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Intention to Test or Mitigate for Radon
Participants' intention to test for radon or take steps to mitigate radon, assessed by asking how soon the participants plan to test for radon or take steps to fix radon.
Measured: Immediately after viewing the messages
