Trial Outcomes & Findings for Risk Information and Skin-cancer Education for Undergraduate Prevention (NCT NCT03979872)
NCT ID: NCT03979872
Last Updated: 2021-07-13
Results Overview
Mean and standard deviation for each sun protection behavior at Visit 1 (baseline), Visit 2 (4 weeks), Visit 3 (8 weeks). "These next questions ask about what you have done in the past four weeks if you were outdoors in the sun for 15 minutes or more. How often did you... " Minimum value =1; Maximum value= 5; Higher scores indicate that participants were more likely to engage in sun protection habits.

SECONDARY outcome
Timeframe: Weeks 0 (Visit 1), 4 (Visit 2), 8 (Visit 3)Population: The difference in the number of participants analyzed at each visit versus overall participants analyzed for each study arm is due to participant attrition over time.
Mean and standard deviation for tan occurrence at Visit 1 (baseline), Visit 2 (4 weeks), Visit 3 (8 weeks). "In the past 4 weeks, how often did you end up with a tan, even if you didn't try to get one?" Minimum value =1; Maximum value= 5; Higher scores indicate that participants received a tan as a result or being outdoors or using an indoor tanning device whether intentional or not.
Outcome measures
| Measure |
Arm 1: Skin Cancer Education Only
n=22 Participants
Participants will be randomized to receive education only.
Skin Cancer Education: \[See arm/group descriptions\]

Arm 2: Skin Cancer Education + UV Photo
n=23 Participants
Participants randomized to receive education + UV photo will have a UV light photo taken of their face to show UV damage in the skin that is invisible to the naked eye in addition to receiving skin cancer education.
Skin Cancer Education: \[See arm/group descriptions\]
UV Photo: \[See arm/group descriptions\]
|
Arm 3: Skin Cancer Education + MC1R Testing
n=24 Participants
Participants randomized to receive education + genetic testing will be asked to provide a saliva sample for MC1R testing in addition to receiving skin cancer education.
MC1R Genetic Testing: \[See arm/group descriptions\]
Skin Cancer Education: \[See arm/group descriptions\]
