About this study

This project will pilot a Just In Time Adaptive Intervention (JITAI) approach to providing feedback on child UVR exposure to children and their parents, with the ultimate goal of improving child use of sun protection strategies (e.g., use of sunscreen, protective clothing) and decreasing UVR exposure and sunburn occurrence. This study will utilize a SmartPhone app. If participants do not have a smartphone, they will be provided with one to use the app.

Read the detailed description

Melanoma is the 6th most common form of cancer in the United States and its incidence has been increasing for the past three decades. While individuals diagnosed with melanoma have a generally optimistic prognosis (overall 5-year survival rates of 91%), once melanoma has metastasized to distant organs, the survival rate drops to only 17%. As a result, prevention and early detection of melanoma when it is more easily treated are of prime importance. Ultraviolet radiation (UVR) exposure is the primary modifiable risk factor for melanoma. Adoption of sun protective behaviors, such as sunscreen use, are essential for decreasing acute (sunburn) and long-term (DNA damage) effects of UVR exposure. Minimizing excess UVR exposure is especially important during childhood since childhood sunburns are a risk factor for melanoma.

Existing interventions for skin cancer prevention in childhood have not been able to provide children and families with real-time feedback and associated prompts related to the child's UVR exposure. Previous research has shown that families struggle with knowing how much UVR exposure their children obtain throughout the course of the day. JITAIs offer a unique opportunity to provide children and their parents with real-time feedback on the child's UVR exposure, as well as reminders for the child to use recommended sun protection strategies. Previous JITAIs have been observed to be effective at reducing sedentary activities, preventing relapse related to alcoholism, and helping with smoking cessation. However, JITAIs have been used more seldom among pediatric populations and have not yet been used to facilitate melanoma preventive strategies among children.

The overall goal of the proposed project is to pilot a JITAI approach to providing feedback on child UVR exposure to children and their parents, with the ultimate goal of improving child use of sun protection strategies (e.g., use of sunscreen, protective clothing) and decreasing UVR exposure and sunburn occurrence.

This study will utilize a SmartPhone app. Participants who provide informed consent and/or assent to participate in the study will be asked to complete activities on the app for 21 days. If children do not have a smartphone, they will be provided with one to use the app.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EUREKA InterventionBehavioural

    Participants will be asked to complete brief questionnaires about the child's sun protection up to six times daily throughout the study. During Week 2, participants will receive feedback and advice messages immediately after completing the questionnaires. During that week, participants will also be asked to collaboratively complete an action planning exercise (delivered to the child's phone) to plan sun protection for a selected outdoor activity that is likely to take place the next day.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Self-reported child sun protection

    This outcome measure will report the frequency of self-report child sun protection using items that separately assess specific sun protection behaviors (e.g., sunscreen use).

    Measured: From baseline to Post-Intervention, up to 21 days

  2. Parent-reported child sun protection

    This outcome measure will report the frequency of parent-report child sun protection using items that separately assess specific sun protection behaviors (e.g., sunscreen use).

    Measured: From baseline to Post-Intervention, up to 21 days

Questions about this trial

What is this clinical trial studying?

A study testing EUREKA Intervention 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 13 inclusion and 3 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: finished, as of the sponsor's last update on 3 Feb 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Self-reported child sun protection (time frame: From baseline to Post-Intervention, up to 21 days). The study lists 2 primary outcomes in all. 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 NCT07204704, which also lists 5 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 3 Feb 2026.
