Promoting Radon Testing Among Mothers of Young Children

Promoting Radon Testing Among Mothers of Young Children: A Translational Clinical Trial

Radon is the second-leading cause of lung cancer after smoking and may contribute to other cancer deaths; children are especially vulnerable due to a larger lung surface area and higher respiratory rates. The goal of this research is to test the feasibility of the radon app to promote radon testing among mothers of children aged 4 or younger when they receive a free radon test kit.

This feasibility study enrolls mothers of children under age 4 who receive a free short-term radon test kit. Participants are introduced to and given access to a smartphone radon app designed to deliver targeted education, step-by-step testing instructions, reminders, and social-sharing prompts. The study measures cognitive outcomes (radon knowledge, self-efficacy for testing, and response efficacy beliefs) before and after app exposure, and behavioral outcomes (whether the test kit is completed and returned for lab analysis, and whether participants share radon information or recommend testing to others). Data collection combines brief baseline and follow-up surveys, app usage analytics (e.g., time in app, modules completed, reminder interactions), and laboratory confirmation of returned kits. Feasibility metrics include recruitment and retention rates, app engagement, and kit return rates.

Inclusion Criteria:

• Participants are female mothers of children aged 4 and under.
• Participants own a smartphone.
• Children brought in for appointments are their biological or adoptive child.

Exclusion Criteria:

• Previous testing for radon within the past two (2) years.
• The mother's child brought in for the appointment is over 4 years of age.
