Sun Exposure and Activities After Skin Cancer: Optimization of mHealth Interventions
SESAME: Sun Exposure and Activities After Skin Cancer: Optimization of mHealth Interventions
Source: ClinicalTrials.gov · Last updated 29 Oct 2026
Brief summary (registry, in English)
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.
