流行病学家经常依赖于自我报告的信息，包括吸烟史，药物使用和职业暴露，因为其他信息来源不可用或难以获得。评估自我报告信息准确性的一种方法是使用其他来源进行逻辑检查。为了评估农业健康研究（AHS）中57，3 11名持牌农药施用者自我报告的农药产品使用历史的质量，我们将自我报告的首次使用十年和总使用年数与农药活性成分首次注册使用的年份进行了比较。我们从美国环境保护局（USEPA）和其他公开来源获得了1994年至1997年AHS初始问卷中52种农药的农药活性成分注册信息。根据注册年份，我们评估了19种农药在使用持续时间或首次使用十年方面的潜在不准确性。在计算潜在的总使用年数时，我们没有考虑化学品从市场上消失的影响，因为存在继续使用的可能性。大多数答复者对首次使用的十年和使用的总持续时间都提供了合理的答复。平均而言，1%的受试者高估了总的可能使用时间，从呋喃丹和毒死蜱的不到1%到咪草烟的5%。首次使用的十年也得到了合理的报告，尽管更多的受试者没有报告首次使用的十年而不是使用的持续时间，平均6%的受试者缺失了单个化学品的十年信息。对于报告首次使用十年的受试者，平均98%的人给出了合理的回答，高估最高的是1971年引入的氰草津（6%报告早期使用）和1985年引入的氯嘧磺隆（7%报告早期使用）。这项分析提供了一个机会，考虑只有一个来源的潜在多报的接触，虽然漏报也可能发生，我们不能评估其作用，也没有这些潜在的不准确性之间的平衡，虽然我们无法直接验证的准确性，受访者的农药使用，这项分析表明，参与者提供合理的信息，他们的农药使用。
Epidemiologists frequently rely on self-reported information regarding a variety of exposures including smoking history, medication use, and occupational exposure because other sources of information are either unavailable or difficult to obtain. One way to evaluate the accuracy of self-reported information is through logic checks using other sources. To assess the quality of the self-reported pesticide product use history of 57,3 11 licensed pesticide applicators in the Agricultural Health Study (AHS), we compared the self-reported decade of first use and total years of use to the year the pesticide active ingredient was first registered for use. We obtained pesticide active ingredient registration information from the United States Environmental Protection Agency (USEPA) and other publicly available sources for the 52 pesticides on the AHS initial questionnaires administered from 1994 to 1997. Based on the registration year, we assessed 19 pesticides for potential inaccuracies regarding duration of use or decade of first use. When calculating potential total years of use, we did not consider the impact of chemicals being removed from the market, since the possibility for continued use existed. The majority of respondents provided plausible responses for both decade of first use and total duration of use. On average, 1% of the subjects overestimated total possible duration of use, ranging from less than 1% for carbofuran and chlorpyrifos to 5% for imazethapyr. Decade of first use was also reasonably reported, although more subject, did not report decade of first use than duration of use, with an average of 6% of subjects missing decade information for an individual chemical. For subjects who reported a decade of first use, 98% gave plausible responses on average, with overestimates highest for cyanazine, introduced in 1971 (6% reported earlier use), and chlorimuron ethyl, introduced in 1985 (7% reported earlier use). This analysis provided the opportunity to consider only one source of potential overreporting of exposure, and while underreporting may have also occurred, we cannot evaluate its role nor the balance between these potential inaccuracies, While we are unable to validate directly the accuracy of a respondent's use of pesticides, this analysis suggests that participants provide plausible information regarding their pesticide use.
