Healthy Homes Study

Official title

Co-developing and Pilot Testing a Risk-tailored, Technology-supported Intervention to Increase Home Radon Testing in New Hampshire and Vermont

Overview

This study is about home air radon testing and has two phases. The goal of the first phase is to learn about renters' and homeowners' views and plans related to radon testing. The main question this phase aims to answer is: 1\. Does taking part in a focus group with information about radon testing change people's plans to test for radon? Participants in the first study phase will: * Take a survey about their views on and plans for radon testing. * Take part in a focus group discussion about radon testing, during which they will receive information about radon testing. * Right after the focus group, take a survey about their plans for radon testing. The second phase is a pilot interventional study. The goal is to test interventions about radon testing with renters and homeowners who smoke and do not smoke. The main questions this phase aims to answer are: 1. Does the recruitment strategy result in enough participants enrolling within 3 months? 2. Will at least 80% of participants complete data collection activities? 3. Will more participants who view an online intervention developed by the researchers request free radon test kits, set them up in their homes, and complete radon testing, compared to participants who view a standard public health infographic? And will even more participants who receive reminder messages, in addition to the online intervention, request free radon test kits, set them up in their homes, and complete radon testing? Participants in this second phase will: * Take a survey about their views on and plans for radon testing. * View an intervention about radon testing. * Right after viewing the intervention, take a survey about their views on and plans for radon testing. * 2 months later, take a survey about what, if any, steps they've taken to test their homes for radon. * Provide the researchers permission to collect data from their State Radon Program on: a) whether they requested a free radon test kit and b) whether testing was completed. Some participants will receive reminder messages for 2 months after viewing the intervention. Researchers will compare an online intervention they developed about radon testing to: a) a standard public health infographic and b) their online intervention combined with reminder messages about radon testing. They will compare the interventions by proportion of participants who: a) request a free radon test kit from their State Radon Programs, b) set-up the radon test kit in their homes, and c) complete radon testing.

Detailed description

This study is a pilot research study.

Interventions

• Behavioral Public health infographic (AIM 3)
  Standard public health infographic about home air radon testing, plus information about requesting a free home air radon test kit
• Behavioral Online health promotion intervention tailored by smoking status (AIM 3)
  Online health promotion intervention with messaging about home air radon testing tailored by the participant's stated smoking status, plus information about requesting a free home air radon test kit
• Behavioral Online health promotion intervention tailored by smoking status, plus reminder messages (AIM 3)
  Online health promotion intervention with messaging about home air radon testing tailored by the participant's stated smoking status, plus information about requesting a free home air radon test kit, plus reminder messages about home air radon testing sent over two months
• Behavioral Focus group with educational overview (AIM 1)
  90-minute online focus group discussion about home air radon testing, plus an educational overview about home air radon testing using a standard public health infographic

Primary outcome measures

• Number of participants enrolled in the study (AIM 3) [Time frame: 3 months]
• Proportion of study participants who complete all study surveys (AIM 3) [Time frame: 2 months]
• Proportion of participants who request a home radon test kit at 18 months (AIM 3) [Time frame: 18 months]
• Proportion of participants who request a home radon test kit at 2 months (AIM 3) [Time frame: 2 months]
• Proportion of participants who set-up a home radon test kit in their home (AIM 3) [Time frame: 2 months]
• Proportion of participants who complete home radon testing at 18 months (AIM 3) [Time frame: 18 months]
• Proportion of participants who complete home radon testing at 2 months (AIM 3) [Time frame: 2 months]

Secondary outcome measures (1)

• Change in participants' intentions to test the air in their homes for radon in the next 12 months (AIM 1) [Time frame: Baseline (pre-test, approximately 1-4 weeks before intervention), immediately after the intervention (post-test)]
