Study Summary
This is a randomized controlled trial testing the efficacy of 4 sun protection interventions--education only; education and mailed sunscreen; education and text message reminders; and education, mailed sunscreen, and text message reminders--among Michigan Operating Engineers. Pre- and post-intervention surveys will be collected to determine changes in sunscreen use and sun burning, the primary outcome variables. The investigators hypothesize that all interventions will increase sunscreen use and reduce burning and that the education-only intervention will have the least effect of the 4 interventions while the education, mailed sunscreen, and text messaging arm will have the greatest effect.
Primary Outcome
Subjects will complete a baseline survey during safety training sessions in Winter when they get the educational intervention. In the past summer, on the days when you were outside in the sunlight, how often did you use sun block (never, some of the time, about half the time, most of the time, always)?
Interventions
