| Abstract: |
| 流行病学调查中不同的资料收集途径其在真实性和可靠性方面可能不尽一致，为评价病人及其代理人（如配偶）对问表问题的回答一致性（可靠性），作者分别对50例肺癌病人及其代理人进行了面对面访问调查。结果示，对计量资料两者回答的基本一致率为84.1%，经配对t检验除吸烟开始年龄外，余均差异无显著性（P>0.05）；对计数资料比较表明，平均一致率为87.8%，各项目经Kappa一致性检验，P均小于0.001。结果与国外文献报道基本一致，并提示在实际工作中对死亡病例作为研究对象，则可以从其代理人那里采集所需的资料。 |

| In epidemiological investigations, the validity and reliability of data under different ways of collection might not be consistent. In order to evaluate the consistency of data collected from cases themselves or from their surrogates(for example, the spouse) through answering the same questionnaire,at personal interview, was carried out among 50 cases of lung cancer and their surrogates respectively.other than the item starting age of smoking by a paired-t test, the results showed that between the two groups of quantitative data sources, the overall consistent rate was 84. l% and the differences were not significant (P >0.05). When Kappa consistency test was used to the count variables, an average consistent rate of 87.8% was noticed, but P values were less than 0.001 for all items. Results from this study were quite similar to those with have been published abroad and suggested that it is credible to collect data from surrogates when dead cases were selected as research subjects. |
