Summary

This trial tested a virtual learning program called SSW Works, designed to help outdoor workers protect themselves from the sun. Over 500 workers and their managers participated. The program provided culturally tailored tips on sunscreen, clothing, and shade use. Researchers measured changes in sun protection habits and sunburn rates after one year.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
SSW Works virtual learning program
What this could lead to
If effective, this program could become a widely used tool to reduce skin cancer risk among outdoor workers.
What could go wrong
This is a completed Phase II trial, so results are not yet known. The program may not significantly change sun protection habits or reduce sunburns.
