Our Australia-wide case-control study of ocular melanoma diagnosed in 1996 to 1997 needed a short telephone interview on sun exposure. We constructed one by examining data from 700 controls ages 40 to 64 years in the Geraldton Skin Cancer Survey in 1988; they had answered a "whole-of-life" questionnaire in a face-to-face interview. Sun exposure in their first 4 decade years of age best predicted their lifetime annual average sun exposure, so the shortened questionnaire asked about sun exposure in these 4 decade years only. Retesting 60 participants 1 year later with the whole-of-life questionnaire gave an intraclass correlation coefficient of 0.65 (95% confidence interval, 0.48-0.78) for ranked total sun exposure between the two interviews; the intraclass correlation coefficient was higher in men (0.73) than in women (0.54). Correlations were also high between parallel measurements of sun exposure on working days in the decade years and in outdoor occupations throughout life in the telephone interview of the ocular melanoma study (Spearman's R = 0.75) and in another study of non-Hodgkin's lymphoma (R = 0.71). Agreement between simultaneous parallel measures of total exposure (nonworking + working day and recreational + occupational exposure) was slightly weaker and of nonworking day and recreational exposure much weaker. Occupational exposure in women was much less strongly correlated with total exposure than it was in men possibly because of their frequently combined work and family roles, which the questionnaires did not try to separate. Research is needed into how this might be done to improve sun exposure measurement in women.
我们在1996年至1997年对澳大利亚范围内诊断出的眼黑色素瘤进行了病例对照研究，该研究需要就阳光暴露情况进行一次简短的电话访谈。我们通过研究1988年杰拉尔顿皮肤癌调查中700名年龄在40至64岁之间的对照者的数据构建了一份访谈内容；他们在面对面访谈中回答了一份“一生”问卷。他们在40岁之前的阳光暴露情况最能预测其一生的年平均阳光暴露量，因此缩短后的问卷仅询问了这40年中的阳光暴露情况。一年后，用“一生”问卷对60名参与者进行重新测试，两次访谈中按等级排列的总阳光暴露量的组内相关系数为0.65（95%置信区间，0.48 - 0.78）；男性的组内相关系数（0.73）高于女性（0.54）。在眼黑色素瘤研究的电话访谈中，十年中工作日阳光暴露的平行测量值与一生中户外职业阳光暴露的平行测量值之间的相关性也很高（斯皮尔曼相关系数R = 0.75），在另一项非霍奇金淋巴瘤研究中相关性也很高（R = 0.71）。总暴露量（非工作日 + 工作日以及娱乐 + 职业暴露）的同步平行测量之间的一致性稍弱，非工作日和娱乐暴露的一致性则弱得多。女性的职业暴露与总暴露的相关性远低于男性，这可能是因为她们的工作和家庭角色经常相互交织，而问卷并未试图区分这一点。需要研究如何做到这一点，以改善对女性阳光暴露量的测量。
