Mobile sun protection support to help young adults stay safe in the sun
Official title: mSHIELD (Mobile Sun Health Intervention EnabLing Daily Protection)
Run by University of Utah · NCT07830394 · Data updated 2026-11-12
This project tests a mobile health program to see if reminders, education, planning tools, and real-time sun exposure information can help young adults protect their skin from excessive sun exposure.

Is this trial a fit for you?
✓Likely a good fit
Adults 18 years or older who have had at least one sunburn in the past year or who report infrequent use of sunscreen with other sun-protection behaviors.
✕Probably not a fit
Individuals who do not use English or who have a personal history of skin cancer may be less likely to benefit or participate in the study.

What this trial studies
This pilot study refines a mobile health system designed to reduce excessive unprotected sun exposure among young adults. Over 4 weeks, participants use an app that delivers text reminders, sun protection education modules, an action planning tool, and real-time UVR weather information. The approach is based on Social Cognitive Theory, targeting self-efficacy and barrier reduction to promote safer sun behaviors. After the intervention, participants complete a post-intervention survey and a follow-up survey one month later to assess usability and behavior changes. This study prioritizes user preferences and pilot testing before a larger trial.
Why it matters
Potential benefit: If successful, the app could help young adults adopt more consistent sun-protection habits and reduce skin cancer risk.
How similar studies have gone: Prior work supports using mobile health tools for behavior change, but applying all four components together for sun protection is innovative and previously untested.
