title: The Montana Radon Study: social marketing via digital signage technology for reaching families in the waiting room.
abstract: OBJECTIVE
  I tested a social marketing intervention delivered in health department waiting rooms via digital signage technology for increasing radon program participation among priority groups.
  
  
  METHODS
  I conducted a tri-county, community-based study over a 3-year period (2010-2013) in a high-radon state by using a quasi-experimental design. We collected survey data for eligible participants at the time of radon test kit purchase.
  
  
  RESULTS
  Radon program participation increased at the intervention site (t38 = 3.74; P = .001; 95% confidence interval [CI] = 4.8, 16.0) with an increase in renters (χ(2)1,228 = 4.3; P = .039), Special Supplementary Nutrition Program for Women, Infants, and Children families (χ(2)1,166 = 3.13; P = .077) and first-time testers (χ(2)1,228 = 10.93; P = .001). Approximately one third (30.3%; n = 30) attributed participation in the radon program to viewing the intervention message. The intervention crossover was also successful with increased monthly kit sales (t37 = 2.69; P = .01; 95% CI = 1.20, 8.47) and increased households participating (t23 = 4.76; P < .001; 95% CI = 3.10, 7.88).
  
  
  CONCLUSIONS
  A social marketing message was an effective population-based intervention for increasing radon program participation. The results prompted policy changes for Montana radon programming and adoption of digital signage technology by 2 health departments.
