Sun Exposure and Activities After Skin Cancer: Optimization of mHealth Interventions
Sponsor: Northwestern University
Summary
The purpose of this study is to evaluate 5 different smartphone administered sun protection interventions that aim to reduce unprotected sun exposure in melanoma survivors. Participants are asked to wear an ultraviolet (UV) device and an activity monitor (Actigraph) to measure their daily UV exposure and track their physical activity for three separate assessment weeks and complete daily surveys. After the first assessment week, eligible participants are assigned up to 5 different sun protection interventions that are administered through a smartphone application for 8 weeks. Following 8-week use of the sun protection interventions, participants complete another assessment week. At the end of the assessment week, participants provide feedback on the design and usability of the UV device, smartphone application and each of the sun protection interventions that they experienced. One year later, participants are contacted again to complete a final assessment week.

Conditions
Interventions
UV Real-Time Alerts
Participants will receive text-based alerts about high-risk sun exposure as assessed by their UV device. If they are assigned this intervention, they will use a UV device.
Track Your Sun Protection
Participants report their clothing and sunscreen use on a digital avatar each time they go outdoors. If they are assigned this intervention, they will use a UV device.
Current Conditions
This displays a participant's location's UVR index and notifies them of ultraviolet radiation forecasts for different times throughout the day.
Health Coaching
Bi-weekly (four times total) a trained health coach will individually call participants to discuss progress towards sun protection goals and provide support and advice. Scheduled calls, pre-interview questions, and goals will be displayed in the app.
Action Planning
Participants will be instructed on how to set action plans for sun protection and will receive information from a mobile app about setting plans for enacting health behaviors and counteracting barriers.
Core Components
All participants receive two core components, messages and lessons. Messages delivers two helpful UV protection tips per week and lessons contains 5 UV education courses for participants to read.
