Interventions and Outcome Measures

Arms

other: mSHIELD (mobile Sun Health Intervention EnabLing Daily Protection)

Participants will complete a 4-week intervention with all intervention components delivered through the study application. Intervention components will include: text messages, sun protection education modules, an action planning module, and ultraviolet radiation (UVR)/weather information. The modules/components are used for the entire 4-week intervention period.

Interventions

Text Message Reminders

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

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

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

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.

Primary outcome measure

  • Proportion of Participants with a Clinically Significant Impact [ Time Frame: up to 2 months from baseline ]
