Adaption of the Skin Sun Sensitivity Scale
Determining Fitzpatrick skin phototypes (FST) allows physicians to assess a person's risk of developing sunburn, and thus the need for sun protection to prevent the development of skin cancer. Reflectance spectrophotometry objectively measures the melanin index (MI) and can assist in determining the accuracy of self-reported FST compared with dermatologist-determined FST. At present, we seek to determine the accuracy of an adapted Skin Sun Sensitivity Scale for individuals of all pigmentation varieties (FST I through VI) as compared with spectrophotometric measurements assessing FST. Our principal objective is to correlate the MI under usual conditions by spectrophotometry with the adapted Fitzpatrick SPT as determined by the patients' responses to the adapted questionnaire.

Time Perspective: Prospective
|Official Title:||Adaption of the Skin Sun Sensitivity Scale for People With All Pigment Varieties|
- Melanin Index by Spectrophotometry [ Time Frame: At baseline ] [ Designated as safety issue: No ]Spectrophotometer measurement is the wavelength of the reflected light measured in nm. It represents the area under the curve for the all wavelengths of light, thus a reading will be expressed as (192 ±30, mean ± SD).
- Participant Self-Report of Fitzpatrick Skin Type [ Time Frame: At baseline ] [ Designated as safety issue: No ]Subjects will be asked to respond to the standard survey questions about ease of sunburning and tanning. (Q1, 2)
- Assessment of Ease of Freckling as a Child and Ethnicity [ Time Frame: At baseline ] [ Designated as safety issue: No ]Subjects will be asked to respond to standard questions self-reporting ease of freckling as child of about 10 years old and ethnic background. (Q3,4,7)
- Assessment of Fitzpatrick Skin Type using the Adapted Skin Phototype Measure [ Time Frame: At baseline ] [ Designated as safety issue: No ]Trained personnel will review interview the subjects' response to survey items 1 and 2 and assign a SPT determined by their responses. (Q9)

A convenience sample
The characteristics of the sample will be monitored to assure that each category of skin type (I- VI) is accrued in sufficient size to support analysis. In addition, the sample will have equal representation from 4 ethnic groups within each skin type category: African American, Asian, Hispanic, or non-Hispanic White. Participants will self-identify as being Asian, Black, Hispanic Black, Hispanic White, or non-Hispanic White.
