Feasibility Study Using a Smartphone Radon App to Promote Radon Testing Among Mothers of Children Aged 4 Years and Younger

What this Trial Is About

Radon is the second-leading cause of lung cancer after smoking and may also contribute to other cancer deaths. Children are particularly vulnerable due to their larger lung surface area and higher breathing rates. This research evaluates the feasibility of using a smartphone radon app to encourage radon testing among mothers of children aged 4 years or younger. The study aims to improve radon knowledge, self-confidence in testing, and promote radon test kit use and sharing of radon information. Participants will receive a free short-term radon test kit and access to a radon app designed to provide targeted education, step-by-step testing guidance, reminders, and prompts for sharing information socially. They are encouraged to download and use the app over a four-month period, engaging with mobile-friendly educational content based on EPA brochures. The study includes a baseline survey before app exposure, a follow-up survey at two months, and tracking of kit completion and return at four months. During the study, participants complete brief surveys at baseline and two months, while app usage is monitored through analytics like time spent and modules completed. The return of test kits is confirmed by laboratory analysis. Researchers measure recruitment and retention rates, app engagement, cognitive outcomes like knowledge and beliefs about radon testing, and behavioral outcomes such as test completion and sharing of radon information. Participation lasts about four months from enrollment to the end of kit tracking.
