A sun protection app (mSHIELD) to reduce unprotected sun exposure in young adults

• Text Message Reminders

  Intervention · 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

  Intervention · 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

  Intervention · 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

  Intervention · 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.
