虽然对物质清单的自我答复可能是获得职业接触信息的一种方便和廉价的方法，但尚未对此类信息的有效性进行评估。本报告的目的是提供一些关于自我报告的职业暴露的有效性的证据。在一项大型病例对照研究的背景下，可以将自我报告与专家评估进行比较，其中一组工业化学家和化学家单独检查每一份工作历史，并决定接触的可能性。研究对象为1979年至1985年期间在加拿大蒙特利尔进行的癌症和职业暴露人群病例对照研究的1,910名男性。对于11种物质中的每一种，通过Kappa统计和计算自我评估与专家评估的灵敏度和特异性，对两种暴露评估方法进行了比较。Kappa值范围为0.33 - 0.64。与专家评估相比，自我评估的特异性一般较高（0.83-0.97，中位数为0.90），但敏感性较低（0.39-0.91，中位数为0.61）。作者的结论是，自我报告的职业暴露不够准确，不足以保证他们在大多数社区为基础的研究中唯一使用。
While self-response to a checklist of substances may be a convenient and inexpensive method for obtaining information on occupational exposure, the validity of such information has not been evaluated. The objective of this report is to provide some evidence concerning validity of self-reported occupational exposures. In the context of a large case-control study, it was possible to compare self-reports with expert assessment, in which a team of industrial hygienists and chemists examined each job history individually and decided on likelihood of exposure. The subjects were 1,910 males who had participated in a population-based case-control study of cancer and occupational exposures conducted in Montreal, Canada, between 1979 and 1985. For each of 11 substances, the two methods of exposure assessment were compared by means of a kappa statistic and by computing the sensitivity and specificity of self-assessment against expert assessment. Kappa values ranged from 0.33 to 0.64. Compared with the expert assessment, specificities of the self-assessment were generally high (0.83-0.97, with a median of 0.90), but sensitivities were low (0.39-0.91, with a median of 0.61). The authors conclude that self-reports of occupational exposure are not sufficiently accurate to warrant their sole use in most community-based studies.
