当使用社会观点进行分析时，疾病对个人工作能力的影响应该是经济评估的一部分。这种影响通过计算生产率成本得到反映。对这些成本的衡量通常是回溯进行的。本研究旨在探讨自填式病假问卷的精确度与准确性。一家公司的员工被要求指出过去2周、4周、2个月、6个月和过去12个月内因病缺勤的天数。绝对差值最大分别为0的受访者百分比。确定了报告与公司登记的因病缺勤之间的1、2、3、4、5、6、7、8和9天或更长天数。此外，还计算了比例差。采用符号秩检验法进行系统差异检验。在报告的数据中，当召回期限限制在2周和4周时，95%的数据与注册数据完全匹配。这一百分比在2个月、6个月和12个月分别降至87%、57%和51%。召回期间的加权平均比例差异分别为32.9%、35.2%、45.3%、34.9%和113.6%。登记病假和报告病假之间没有系统性的积极或消极差异。结果表明，病假追溯测量的召回期限根据精确度水平而有所限制，这似乎适合于研究对象和研究目的。我们建议使用不超过3个月的召回期限。(C)2000爱思唯尔科学有限公司。保留所有权利。
The impact of disease on the ability of a person to perform work should be part of an economic evaluation when a societal viewpoint is used for the analysis. This impact is reflected by calculating productivity costs. Measurement of these costs is often performed retrospectively. The purpose of our study was to study precision and accuracy of a retrospective self-administered questionnaire on sick leave. Employees of a company were asked to indicate the number of days absent from work due to illness during the past 2 weeks, 4 weeks, 2 months, 6 months, and the past 12 months. The percentage of respondents with an absolute difference of a maximum of respectively 0. 1, 2, 3, 4, 5, 6, 7, 8, and 9 or more days between reported, and company-registered absence due to illness was determined. Besides this, the proportional difference was calculated. A systematic difference was tested with a signed rank test. Of the reported data, 95% matched the registered data perfectly when the recall period was limited to 2 and 4 weeks. This percentage decreased to 87%, 57%, and 51% for 2 months, 6 months, and 12 months. The weighted mean proportional differences for the recall periods were respectively 32.9, 35.2, 45.3, 34.9, and 113.6%. No systematic positive or negative difference was found between registered and reported sick leave. The results suggest that the recall period for retrospective measurement of sick leave is limited according to the precision level, which seems to be appropriate for the subject and the purpose of the study. We recommend using a recall period of no more than 3 months. (C) 2000 Elsevier Science Ltd. All rights reserved.
