Few questionnaires used in monitoring sun-related behaviour have been tested for validity.
We established the criteria validity of a questionnaire developed for monitoring population sun-related behaviour.
During May-August 2013, 664 Danes wore a personal electronic ultraviolet radiation (UVR) dosimeter for 1 week that measured their outdoor time and dose of erythemal UVR exposure. In the following week, they answered a questionnaire on their sun-related behaviour in the measurement week.
Outdoor time measured by dosimetry correlated strongly with both outdoor time and the developed exposure scale measured in the questionnaire. Exposure measured in standard erythema dose (SED) by dosimetry correlated strongly with the exposure scale. In a linear regression model of UVR (SED) received, 41% of the variation was explained by skin type, age, week of participation and exposure scale, with exposure scale as the main contributor. The weekly sunburn fraction correlated strongly with the number of ambient sun hours (r = 0·73, P < 0·001).
This criteria-validated questionnaire provides evidence of the exposure that the questionnaire aimed to measure. The evidence provided showed a strong link between the objectively measured behaviour and the behaviour measured by this survey construct. The questionnaire is the first validated tool to measure the UVR exposure in a national population-based sample.
用于监测与阳光相关行为的问卷中，很少有经过有效性验证的。
我们制定了一个用于监测人群与阳光相关行为的问卷的准则有效性。
在 2013 年 5 月至 8 月期间，664 名丹麦人佩戴了一个个人电子紫外线辐射（UVR）剂量计，持续一周，以测量他们的户外活动时间和红斑 UVR 暴露剂量。在接下来的一周内，他们回答了一个关于他们在测量周内与阳光相关行为的问卷。
剂量计测量的户外活动时间与问卷中测量的户外活动时间和开发的暴露量表高度相关。剂量计测量的标准红斑剂量（SED）暴露与暴露量表高度相关。在 UVR（SED）接收的线性回归模型中，41%的变异由皮肤类型、年龄、参与周和暴露量表解释，其中暴露量表是主要贡献者。每周晒伤率与环境日照小时数呈高度相关（r = 0.73，P < 0.001）。
这个经过准则验证的问卷为问卷旨在测量的暴露提供了证据。提供的证据表明，客观测量的行为与该调查结构测量的行为之间存在很强的联系。该问卷是第一个用于测量基于全国人口样本的 UVR 暴露的经过验证的工具。
