The objective of this study was to compare the accuracy of self-reported skin cancer risk outcome measures proposed as standards by prevention experts to aggregated estimates of behavior from weekly diaries. Weekly electronic diaries of ultraviolet radiation (UVR) behaviors, initially validated by comparison with daily electronic diaries, were used to assess the accuracy of commonly used end-of-summer self-reported measures among 250 adults. Results revealed low biases, and good correspondence between simple open-ended self-reported estimates of days outside, hours outside, sunbathing days and hours, and days outside when not protected by either sunscreen, long-sleeved shirts, hats, or shade. Rating scale measures commonly used in the current literature and those recently recommended as standards by a workshop of experts showed evidence of being non-interval and lacking precision for more frequent behavior (e.g., >1 h sun exposure daily). These data indicated that open-ended frequency self-reports of skin cancer risk behaviors that follow procedures designed to increase accuracy were reliable over a summer-long period.
本研究的目的是比较预防专家提出的作为标准的自我报告皮肤癌风险结果测量与每周日记中汇总的行为估计的准确性。最初通过与每日电子日记进行比较验证的每周紫外线辐射 (UVR) 行为电子日记，用于评估 250 名成年人中常用的暑期末自我报告措施的准确性。结果显示，简单的开放式自我报告的外出天数、外出时间、日光浴天数和时间以及没有防晒霜、长袖衬衫、帽子或遮荫保护时的外出天数的估计值存在低偏差，并且与实际值高度一致。目前文献中常用的评分量表测量值以及最近由专家研讨会推荐的标准测量值，均显示出非区间性和缺乏对更频繁行为（例如每天 >1 小时的阳光暴露）的精确性的证据。这些数据表明，遵循旨在提高准确性的程序的皮肤癌风险行为的开放式频率自我报告在整个夏季都是可靠的。
