-Summary

This study aims to characterize UV exposures among NMSC patients (those with a history of skin cancer) and to pilot an innovative behavioral intervention to decrease modifiable UV exposures. It will use UV dosimeters to objectively measure UV exposure and provide time and activity specific UV data on an individual level. These data will be used to develop a targeted and personalized behavioral feedback plan with counseling aimed at effective sun exposure behavior change

+Detailed description

The study will focus on helping to prevent NMSC and its associated morbidity through learning when patients are unintentionally exposed to extreme UV radiation. It will then help to create manageable and realistic behavioral interventions to reduce exposure, while also educating patients of the dangers of abundant sun exposure.

+Arms and interventions

Arm	Type	Interventions	Description
UV Dosimeter	Experimental	Behavioral: UV Counseling	UV Dosimeter will measure participants' UV exposure for two separate 3-week periods.

UV Counseling (Behavioral): Participants will self-report their knowledge and attitudes related to UV exposure. They will then wear a dosimeter for 3 weeks. After, the study team will counsel the participants on their UV levels and exposure, creating a personal plan and advice for avoiding sun exposure before letting the participants wear the dosimeter for an additional 3 weeks.

+Outcome measures

Primary outcomes

Identify Discrepancies of Self-Reported Sun Exposure and Actual Sun Exposure [Start of study to end of study, up to 3 months]: Measured using individual dosimeters and comparing it to what participants state they believe their level of sun exposure is
Identify Discrepancies of Self-Reported Sun Exposure and Actual Sun Exposure [Start of study to end of study, up to 3 months]: Compare specific sun exposure behaviors responsible for the level of exposure versus what could be done to lessen it

Secondary outcomes

Behavioral Intervention and immediate follow-up [Start of study to end of study, up to 3 months]: Participants will receive a personalized feedback plan and the success of the plan will be measured through individual dosimetry. We will track real time change in sun exposure based on repeat UV dosimetry.
Long Term Follow Up - longitudinal change in sun exposure based on dosimetry [Start of study to end of study, up to 3 months]: Track the longitudinal change in sun exposure comparing baseline UV dosimetry measurements to 3 month follow up dosimetry measurements to determine if the changes observed in outcome 3 are maintained.
