NCT07830394

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Proportion of Participants with a Clinically Significant Impact

    To determine whether a prototype mHealth system improves use of sun protection strategies among young adults. Data at the one-month post-intervention surveys will be analyzed and compared to baseline values. For this study, the criteria for a clinically significant impact will be that a participant reports no sunburns and now frequently uses sunscreen and at least one other sun protection method during outdoor time. This outcome measure will report the proportion of participants with a clinically significant impact.

    up to 2 months from baseline

Study Arms (1)

mSHIELD (mobile Sun Health Intervention EnabLing Daily Protection)

OTHER

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.

Behavioral: Text Message RemindersBehavioral: Sun Protection Education ModulesBehavioral: Action Planning ModuleBehavioral: UV Radiation (UVR) Weather Information

Interventions

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.

mSHIELD (mobile Sun Health Intervention EnabLing Daily Protection)

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.

mSHIELD (mobile Sun Health Intervention EnabLing Daily Protection)

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.

mSHIELD (mobile Sun Health Intervention EnabLing Daily Protection)

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.
