Brief 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.

Outcome Measures
Primary Outcomes (4)
Sunscreen use
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)?
Baseline
Sun Burning
Subjects will complete a baseline survey during safety training sessions in Winter when they get the educational intervention. On average, how many times did you get a sunburn this past summer (0, 1, 2, 3, 4 or more times)?
Baseline
Sunscreen use
Subjects will be texted or phoned this question monthly during the intervention period and will again receive this question on the longer follow up survey up to 5 months after the interventions end. 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)?
Post-intervention
Sun Burning
Subjects will be texted or phoned this question monthly during the intervention period and will again receive this question on the longer follow up survey up to 5 months after the interventions end. On average, how many times did you get a sunburn this past summer(0, 1, 2, 3, 4 or more times)?
Post-intervention
Study Arms (4)
Sunscreen
EXPERIMENTALTo 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.
Text Message Reminders
EXPERIMENTALAs 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!").
Sunscreen and Text Message Reminders
EXPERIMENTALJust as multimodal interventions such as surgery and radiation can be used to treat skin cancer, multimodal behavioral interventions may reduce sun burning and prevent skin cancer. To determine if the combination of these interventional components results in improvements above and beyond the individual parts, both sunscreen and text messaging interventions will be provided in addition to education.
Education
ACTIVE COMPARATORA 30-minute, picture enhanced power point presentation will be offered to all Operating Engineers during their annual safety trainings. The content of the power point presentation will include information on incidence and prevalence of skin cancer especially among outdoor workers, types of skin cancers and skin cancer risk, sunburn, Sun Protection Factor (SPF), sun protection behaviors including sunscreen use, correct application of sunscreen, types of products, and the new Food and Drug Administration (FDA) labeling of sunscreen products. In addition, other sun protection behaviors such as wearing hats, sunglasses, using shade, etc., will be discussed.
