Study Arms:
- Focus Group (Type: NO_INTERVENTION): 32 subjects~Focus group: It is expected that each participant will provide comments during the 2 hours of the focus group. It will take about one month to enroll the subjects. The audio files should be transcribed and the analysis completed in 60 days. The analysis will determine enablers and barriers to sun protected outdoor activities and determine strategies for achieving sun protected outdoor activities. Baseline knowledge of sun protection performed prior to and at end of focus group.
- Usability testing (Type: NO_INTERVENTION): 10 subjects~Usability test with structured interview: Each participant will use the sensor for 14 days and transmit data with the app installed on their mobile phone. It will take about one month to enroll the subjects. The analysis of the structured interview is completed in one week. Baseline knowledge of sun protection performed prior to and at end of usability test.
- Cohort Study 1-Arm 1 (Type: ACTIVE_COMPARATOR): 31 subjects~First cohort study: It is expected that melanoma survivors will wear the sensor and transmit data for 21 days in the warm weather months of June-Aug 2019. It will take about 2 months to enroll the subjects. Subjects will receive daily text messages in a sequence starting with behavioral facilitation, outcome expectancies, self-efficacy, and self-regulation. On day 10, participants will receive a text message prompting review and reflection on the prior 10 days of UV exposure. Participants will be randomized in Arm 1 to receive a survey item inviting selection of strategies to achieve sun-protected outdoor activities (structured goal attainment). Baseline knowledge of sun protection performed prior to and at end of intervention.
- Structured Interviews (Type: NO_INTERVENTION): 20 young adults, ages 18-39 will participate in structured interviews to determine their barriers and enablers of sun exposure and sun protection. Eligible subjects will have at least one hour a day outdoors with 30 minutes of the hour being consecutive. It will take about 3 months to enroll the subjects. The audio files will be transcribed and analysis completed in 60 days. Baseline knowledge of sun protection will be performed prior to and after structured interviews.
- Cohort Study 2 (Type: NO_INTERVENTION): Second cohort study: 42 young adult participants will recall the number of sunburns experienced in the 28 days prior to enrolling in the study. Then, the same young adult participants will wear the UV sensor daily for 28 summer days. Participants will receive a warning on their mobile phone if the UV dose approaches the dose anticipated to cause sunburn in unprotected skin. Participants will record the number of days in which they get a sunburn. Baseline knowledge of sun protection performed prior to and at end of study.
- Cohort Study 1- Arm 2 (Type: ACTIVE_COMPARATOR): 29 subjects will receive daily text messages in a sequence starting with behavioral facilitation, outcome expectancies, self-efficacy, and self-regulation. On day 10, participants will receive a text message prompting review and reflection on the prior 10 days of UV exposure. Participants will be randomized in Arm 2 to submit a free text description of their strategy (unstructured goal attainment). Baseline knowledge of sun protection performed prior to and at end of intervention.

Based on this trial design, predict the completion outcome and termination type (if applicable).
