Interventions

Text Message Reminders — BEHAVIORAL
Participants will receive text message reminders twice a week. These messages will remind participants to use sunscreen or other forms of sun protection and will include brief facts about sun safety and environmental risks.
Sun Protection Education Modules — BEHAVIORAL
The education section consists of 5 modules on sun protection basics, ultraviolet (UV) exposure, skin health, sunscreen use, and tanning. Each module takes about 5 to 10 minutes to read.
Action Planning Module — BEHAVIORAL
The app will guide participants through creating a specific plan for using sun protection during a routine outdoor activity. Completing an action plan takes about 5 minutes. Participants will be asked to complete two action plans during the study and prompted to review these plans weekly.
UV Radiation (UVR) Weather Information — BEHAVIORAL
The UVR Weather feature displays information similar to what is available in many weather apps, with a focus on the sunburn risk hours. The display also shows different levels of UV risk throughout the day and indicates the current UV risk based on real-time UV Index. Participants will receive a daily notification summarizing the UV information for that day.

Study Details

The overall purpose of this proposal is to refine a mobile-health (mHealth) system to reduce excessive unprotected sun exposure among young adults. Participants will complete a 4-week intervention with all intervention components delivered through the mHealth application. Intervention components include Text Message Reminders, Sun Protection Education Modules, Action Planning Module, and UV Radiation (UVR) Weather Information.
