Sunburn

The goal of this randomized controlled trial is to test the efficacy of a dissonance induction intervention compared to a control group on tanning in 278 young adult tanners. The primary outcome will be tanning at 3-months. Secondary outcomes include tanning at 15-months and sunburn and sun protection use 3- and 15-months post-intervention. The main question it aims to answer is whether the intervention reduces tanning and sunburns and increases use of sunscreen among young adults who tan. Participants will be incentivized to develop sun safety and anti-tanning messaging for a social media campaign and to recruit their social ties to engage with those messages. They will then be asked to complete surveys on tanning and sun protection at baseline, 3-, and 15 months. They will also complete monthly surveys to report sunburns. The dissonance induction intervention is based on a highly effective and internationally disseminated eating disorder prevention program that has reached over 3.5 million people around the world.
