Blank cells indicate that a particular sun exposure metric is unavailable for that measure.
a
Sun Habits Survey items were rated on Likert scales. For sun-protection methods, response scales ranged from 1 (Never) to 5 (Always). For time outdoors, response scales were converted to minutes of exposure (e.g., a response of “1 to 2 h” was assigned a value of 90 min).
b
Overall exposure scores are uniquely computed by the MUSE Inventory. These scores represent minutes of unprotected sun exposure, adjusted for the percentage of the body that was exposed.
