目的：自我报告是流行病学研究中常用的方法，然而，很少有数据存在的可靠性和有效性，这种方法引出相关的信息诊断结直肠癌。我们研究了重测信度和效度的结直肠癌患者报告的过程中，他们的diagnosis.Study设计和设置：116名参与者完成了两个电话采访，我一个月分开，和95个全科医生（GP）完成了书面问卷，以引出有关的信息的关键要素的过程中，诊断结直肠癌。直肠出血等急性症状比一般症状有更高的信度和效度。结肠镜检查是最准确的回忆诊断测试。诊断日期和结肠镜检查日期的回忆具有较高的重测信度。参与者和全科医生提供的诊断测试日期之间存在相当大的差异，但没有证据表明在特定方向上存在偏见。准确性的回忆并没有减少从diagnosis increased.Conclusion时间：本研究证实，自我报告的症状，测试，并在结直肠癌诊断途径的日期一般是可靠的，但是，报告的症状和测试的有效性可以是中度至差。(c)2008年爱思唯尔公司All rights reserved.
Objective: Self-report is commonly used in epidemiologic studies; however, few data exist on the reliability and validity of this method for eliciting information related to the diagnosis of colorectal cancer. We examined the test-retest reliability and validity of colorectal cancer patients reporting on the process of their diagnosis.Study Design and Setting: One hundred and sixteen participants completed two telephone interviews, I month apart, and 95 general practitioners (GPs) completed a written questionnaire, to elicit information relating to key elements of the process of diagnosis of colorectal cancer.Results: Acute symptoms such as rectal bleeding had higher reliability and validity than more general symptoms. Colonoscopy was the most accurately recalled diagnostic test. Recall of diagnosis date, and date of colonoscopy, had high test-retest reliability. There were considerable differences between dates of diagnostic tests given by participants and GPs, but there was no evidence of a bias in a particular direction. Accuracy of recall did not diminish as time from diagnosis increased.Conclusion: This study confirms that self-reported symptoms, tests, and dates in the colorectal cancer diagnostic pathway are generally reliable; however, the validity of reported symptoms and tests can be moderate to poor.
