Lung Cancer (Diagnosis)
Conditions
Brief summary
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.
Detailed description
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| T1 (baseline: pre-exposure survey, distribution of free radon test kit) | 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) | 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) | 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. |
