Actual (reported)The purpose of this study is to determine the efficacy of the Sun-safe Habits Intervention and Education (SHINE) intervention in improving sun protection use and decreasing intentional tanning among high school students. It's anticipated that 30 schools will be randomized into the trial, with approximately half assigned to SHINE and the other half assigned to standard education. After randomization and a baseline assessment, each school will receive two in-class intervention sessions delivered by an interventionist. Follow-up assessments will be completed one month post-intervention, 3-4 months post-intervention, one year post-baseline, and one year post-intervention.

Actual (reported)Sunscreen Application Behavior Changes Assessed Via Sun Habits Survey
Mean/standard deviation of the difference in sunscreen application occurrence between timepoints. "These next questions ask about what you have typically done in the past month when you were outdoors in the sun for 1 hour or more. How often did you wear sunscreen?" Minimum value = 1; Maximum value = 5; Higher scores indicate a better outcome
Baseline Assessment (Wk 0), Post-Assessment (Wk 32-36), Follow-up #1 (Wk 36-40), Follow-up #2 (Wk 44-52), Follow-up #3 (Wk 84-88)
Sunscreen Re-Application Behavior Changes Assessed Via Sun Habits Survey
Mean/standard deviation of the difference in sunscreen re-application occurrence between timepoints. "These next questions ask about what you have typically done in the past month when you were outdoors in the sun for 1 hour or more. How often did you re-apply sunscreen after being outside for 2 hours, in the water, or sweating?" Minimum value = 1; Maximum value = 5; Higher scores indicate a better outcome
Baseline Assessment (Wk 0), Post-Assessment (Wk 32-36), Follow-up #1 (Wk 36-40), Follow-up #2 (Wk 44-52), Follow-up #3 (Wk 84-88)
Long Sleeved Shirt Behavior Changes Assessed Via Sun Habits Survey
Mean/standard deviation of the difference in long sleeved shirt occurrence between timepoints. "These next questions ask about what you have typically done in the past month when you were outdoors in the sun for 1 hour or more. How often did you wear a shirt with sleeves that covered your shoulders?" Minimum value = 1; Maximum value = 5; Higher scores indicate a better outcome
Change in Sunburn Occurrence Assessed Via Sun Habits Survey
Baseline (Wk 0), Post-Intervention (32-36 Wks), Follow-Up 1 (36-40 Wks), Follow-Up 2 (44-52 Wks), Follow-Up 3 (84-88 Wks)
Change in Ultraviolet Radiation (UVR) Exposure Assessed Via UVR Monitor
Baseline (Wk 0), Post-Intervention (32-36 Wks), Follow-Up 1 (36-40 Wks), Follow-Up 2 (44-52 Wks), Follow-Up 3 (84-88 Wks)
Participants will be randomized to receive an intervention that provides information on skin cancer and preventive strategies, features a personalized skin cancer prevention packet that focuses on students' UVR exposure and skin cancer risk, and includes the creation of a individualized sun protection action plan.
Participants will be randomized to receive information that covers general skin cancer education for pediatric populations.

Mean/standard deviation of the difference in time spent in the sun to get tan between timepoints.

Change in Tanning Behaviors Assessed Via Youth Risk Behavioral Surveillance System
Mean/standard deviation of the difference in student's indoor and outdoor tanning behaviors within the last month will be assessed using items from the Youth Risk Behavioral Surveillance System. Unintentional outdoor tanning will also be assessed. "In the past (time frame), how many times did you use an indoor tanning device such as a sunlamp, sunbed or tanning booth? (Do not count getting a spray-on tan)." Minimum value = 0; Maximum value = 5; Higher scores indicate a worse outcome "In the past (time frame), how many times did you sunbathe or tan outdoors?" Minimum value = 0; Maximum value = 5; Higher scores indicate a worse outcome "In the past (time frame), how many times did you end up with a tan, even if you didn't try to get one?" Minimum value = 0; Maximum value = 5; Higher scores indicate a worse outcome
