EUREKA: Evaluating Ultraviolet Radiation Exposure in Kids for Adaptive Intervention

NCT07204704 | Completed

• 1 other identifier: HCI121617
• Study Type: interventional
• Target: 78
• Locations: 1 country
• Sites: 1

Brief Summary

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.

Skin Cancer

Outcome Measures

Primary Outcomes (2)

• 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).

  From baseline to Post-Intervention, up to 21 days

• 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).

  From baseline to Post-Intervention, up to 21 days

Study Arms (1)

EUREKA Intervention

OTHER

This arm will utilize a SmartPhone app to deliver assessments and interventions for 21 days

Behavioral: EUREKA Intervention

Interventions

EUREKA Intervention BEHAVIORAL

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.
