One in five US adults will be diagnosed with skin cancer. As most skin cancers are attributable to sun exposure, this risk factor is an important target for research and intervention. Most sun exposure measures assess frequency of specific sun-protection behaviors, which does not account for the use of multiple, potentially overlapping sun-protection methods. In contrast, the Daily Minutes of Unprotected Sun Exposure (MUSE) Inventory assesses sun-protection behavior during self-reported activities, providing several useful metrics, including duration of unprotected sun exposure on 17 body sites, combined to yield an overall MUSE score weighted by percent of body exposed. The present study was conducted July-September 2017, in Chicago, IL USA. For 10 days, participants (39 melanoma survivors; = 58.59, 64.5% female) wore an ultraviolet radiation (UVR) sensor and completed the Daily MUSE Inventory each evening. The Sun Habits Survey was completed at the end of the study. Outdoor time reported in the MUSE Inventory significantly predicted outdoor time recorded by UVR sensors, = 0.53, < .001. For all sun-protection behaviors except shade, reports from the Daily MUSE Inventory (i.e., percentage of outdoor time a particular strategy was used) correlated with frequency ratings of the same strategy from the Sun Habits Survey (s = 0.66-0.75, < .05). In sum, the Daily MUSE Inventory corresponds with sensor and survey data, and provides a novel metric of unprotected sun exposure that will be useful for evaluating overall extent of sun exposure, including exposure on several smaller body sites that are at high risk for skin cancer.
五分之一的美国成年人将会被诊断出患有皮肤癌。由于大多数皮肤癌都归因于阳光照射，因此这一风险因素是研究和干预的重要目标。大多数阳光照射测量方法评估的是特定防晒行为的频率，这并未考虑到多种可能重叠的防晒方法的使用情况。相比之下，每日无保护阳光暴露分钟数（MUSE）量表评估的是自我报告活动期间的防晒行为，提供了几个有用的指标，包括17个身体部位无保护阳光暴露的时长，这些指标综合起来得出一个根据身体暴露百分比加权的总体MUSE分数。本研究于2017年7月至9月在美国伊利诺伊州芝加哥进行。在10天时间里，参与者（39名黑色素瘤幸存者；平均年龄=58.59岁，64.5%为女性）佩戴紫外线辐射（UVR）传感器，并在每天晚上完成每日MUSE量表。在研究结束时完成了太阳习惯调查。MUSE量表中报告的户外时间显著预测了UVR传感器记录的户外时间，r = 0.53，p <.001。对于除了遮荫之外的所有防晒行为，每日MUSE量表的报告（即使用特定策略的户外时间百分比）与太阳习惯调查中相同策略的频率评分相关（rs = 0.66 - 0.75，p <.05）。总之，每日MUSE量表与传感器和调查数据相符，并提供了一种无保护阳光暴露的新指标，这将有助于评估阳光暴露的总体程度，包括对几个皮肤癌高风险较小身体部位的暴露。
