Summary
Brief summary (as posted)
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.

- type
- EXPERIMENTAL
- label
- Sunscreen
- description
- To reduce barriers to obtaining sunscreen and serve as cues to action, this group will be mailed during the months of May through September, a supply of SPF30 sunscreen lotion (known to prevent sun burning and skin cancer). The mailing will consist of large bottles of sunscreen and a small bottle that can be refilled and attached to their huge key rings that hang off of their belts.

- EXPERIMENTAL
- label
- Text Message Reminders
- description
- As cues to action, this group will receive 60 cellular telephone text-messages on three random mornings per week during the month of May, June, July, August, and September when UV rays are the highest. Using an internet text-messaging service, the messages will be computer generated and sent to Operating Engineers and contain information about weather conditions and various reminders (e.g., "Put on sunscreen today" or "Wow, it's a hot one, you know what to do!").
