Promoting Radon Testing Among Mothers of Young Children

BEHAVIORAL

The radon app

Participants will be asked to use the radon app.

T1 (baseline: pre-exposure survey, distribution of free radon test kit)

Time frame: Initial Enrollment to 2 months after enrollment

T1 (baseline: pre-exposure survey, distribution of free radon test kit). The pre-expsosure survey will measure: Primary endpoints: (1) Radon knowledge, 20 true/false items); (2) self-efficacy, response efficacy, and sharing intention (7-point Likert).

T2 (post-exposure survey at 2 months)

Time frame: 2 months after enrollment

T2 refers to the time point where participants will complete the post-exposure survey, which will happen two months after T1. The primary endpoints are: (1) Changes in radon knowledge from T1 to T2, as measured by the number of correct responses to a series of 20 true/false questions (e.g., "The EPA recommends that homes with 4 picocuries per liter (pCi/L) or more of radon should be fixed."); (2) Changes in self-efficacy, response efficacy, and sharing intention from T1 to T2, measured by 7-point Likert scales; (3) Radon information shared with others and recommended to others to test their houses for radon from T1 to T2. It will be measured by a series of yes/no questions. Analyses: Aim 1-directional dependent t-tests for mean changes; McNemar's test for paired proportions of sharing.

T3 (end of kit tracking at 4 months)

Time frame: 4 months after last enrollment

Number of radon test kits used and returned to the laboratory by participants. Directional McNemar's test for kit return proportions T1 vs T3.

What is a clinical trial?

A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.

Is it safe to participate?

Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.

Will I be compensated?

Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.

Will I receive a placebo instead of treatment?

When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.

Can I leave a trial if I change my mind?

Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.

How long does a clinical trial last?

Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
