This research compared personal sunlight exposure times monitored electronically within suburban Australian environments against self-report paper journals for determining the timing and total duration of individual exposure to daily solar radiation. A total of 90 Electronic Sun Journal (ESJ) daily readings and self-report timing and duration estimates of exposure for weekend and weekdays were compared. A Wilcoxon ranked sign test showed a significant difference (V = 157, p < 0.001) between the duration of exposure recorded electronically and the duration of exposure that was self-reported in a diary. There was also found to be a statistically significant difference between total exposure time measured using both methods for weekends (V = 10, p < 0.001) and weekdays (V = 87, p < 0.001). General trends in outdoor exposure timing confirmed that the most frequent daily exposures received over the weekend occurred between one and two hours earlier than the most frequent exposures received on weekdays. This preliminary research found that exposure durations as recorded by the ESJ were longer on the weekends compared to weekdays (W = 402, p < 0.001) and confirmed that the ESJ is a viable alternative to self-reporting diaries.

电子太阳日记与自我报告太阳日记：记录个人阳光照射方法的比较

这项研究将澳大利亚郊区环境中电子监测的个人阳光照射时间与自我报告的纸质期刊进行比较，以确定个人每日太阳辐射照射的时间和总持续时间。比较了总共 90 个电子太阳杂志 (ESJ) 的每日读数以及周末和工作日暴露的自我报告时间和持续时间估计。Wilcoxon 等级符号测试显示电子记录的暴露持续时间与日记中自我报告的暴露持续时间之间存在显着差异 (V = 157, p < 0.001)。还发现使用这两种方法测量的周末（V = 10，p < 0.001）和工作日（V = 87，p < 0.001）的总暴露时间之间存在统计学显着差异。户外暴露时间的总体趋势证实，周末最频繁的每日暴露比工作日最频繁的暴露提前一到两个小时。这项初步研究发现，与工作日相比，ESJ 记录的暴露持续时间在周末更长（W = 402，p < 0.001），并证实 ESJ 是自我报告日记的可行替代方案。
