Brief 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.

Interventions

BEHAVIORALUV Counseling

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.

Intervention model description

Each participant will self-report skin protective behaviors and attitudes before wearing a UV dosimeter for 3 weeks. After the wear period, the study team provides feedback based on UV exposure. The participant will then wear the device again for 3 weeks.

Design outcomes

Primary

MeasureTime frameDescription
Identify Discrepancies of Self-Reported Sun Exposure and Actual Sun ExposureStart of study to end of study, up to 3 monthsMeasured using individual dosimeters and comparing it to what participants state they believe their level of sun exposure is

Secondary

MeasureTime frameDescription
Behavioral Intervention and immediate follow-upStart of study to end of study, up to 3 monthsParticipants 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 dosimetryStart of study to end of study, up to 3 monthsTrack 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.
