About this study
Official title: mSHIELD (Mobile Sun Health Intervention EnabLing Daily Protection)
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.
Read the detailed description
mHealth tools provide an ideal opportunity for reducing young adults' UVR exposure. mSHIELD intervention components were selected to target key constructs (e.g., self-efficacy, barrier reduction) within Social Cognitive Theory (SCT) which are associated with sun protection behaviors. The initial concept for the mSHIELD intervention includes the following four components: real-time UVR alerts and feedback; UVR weather forecasts; text messages; and action planning. Although these components provide a good fit with SCT constructs and utilize evidence-based behavior change strategies, they have rarely been used in the context of mHealth for sun protection, and this will be the first mHealth intervention for sun protection to apply all four of these components simultaneously. Therefore, prior to testing mSHIELD in a large study, it will be important to refine components based on user preferences and pilot tests.
To test the pilot intervention, 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 UVR/weather information. The modules/components are used for the entire 4-week intervention period. Immediately following the 4-week intervention, participants will be asked to complete a post-intervention survey and study interview. Participants will also be asked to complete a survey one month post-intervention. Participants will receive up to 5 reminders to complete each study activity through each of their approved communication methods (e.g., email).
Data collected 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; a priori, a benchmark of at least 50% of participants reaching this criteria is set to indicate whether the intervention can proceed to larger-scale testing or if further refinements are needed.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Text Message RemindersBehavioural
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 ModulesBehavioural
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 ModuleBehavioural
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 InformationBehavioural
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
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.
Measured: up to 2 months from baseline

Questions about this trial
What is this clinical trial studying?
A study testing Text Message Reminders, Sun Protection Education Modules and Action Planning Module in people with Skin Cancer, run by University of Utah at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 24 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Tammy Stump, PhD (801-646-4201, Tammy.Stump@hci.utah.edu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Proportion of Participants with a Clinically Significant Impact (time frame: up to 2 months from baseline). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07830394, which also lists 16 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Sep 2026.
