必须确认来自自填问卷的历史信息的准确性。我们报告的研究结果进行评估的可靠性和有效性的数据收集从一个全面的癌症危险因素问卷开发的得克萨斯大学M。D.安德森癌症中心。对随机抽取的80名受访者和70名非受访者的基本人口统计数据进行比较，没有发现根本的种族或社会经济差异。我们通过审查72份病历，使用严格的诊断标准进行验证，以验证自我报告的既往疾病，手术程序和癌症。我们注意到自我报告和记录的疾病和手术之间的实质性一致。除了9例转移性疾病分类错误的患者外，原发性癌症的验证非常好。我们通过电话采访50名患者来确定可靠性。具有二分法结果的问题（例如，吸烟状况）得到可靠回答;然而，那些需要定量的（例如，饮酒量）在访谈中报告的准确性较低。虽然我们认识到自我管理问卷的局限性，但我们相信该计划将发展成为一个全面的，标准化的，易于访问的患者风险因素数据库。
The accuracy of historical information derived from self-administered questionnaires must be confirmed. We report the results of studies conducted to assess the reliability and validity of data collected from a comprehensive cancer risk factor questionnaire developed at The University of Texas M. D. Anderson Cancer Center. A comparison of the basic demographic data of a randomly selected sample of 80 respondents and 70 nonrespondents revealed no fundamental ethnic or socioeconomic differences. We verified self-reported past illnesses, surgical procedures, and cancers by reviewing 72 patient charts, using stringent diagnostic criteria for verification. We noted substantial agreement between self-reported and documented illnesses and operations. With the exception of nine patients who misclassified metastatic disease, the verification of exception of nine patients who misclassified metastatic disease, the verification of primary cancers was excellent. We determined reliability by interviewing 50 of these patients by telephone. Questions with a dichotomous outcome (e.g., smoking status) wre reliably answered; however, those requiring quantifiction (e.g., amount of alcohol consumed) were less accurately reported on interview. While we recognize the limitations of self-administered questionnaires, we believe this program will develop into a comprehensive, standardize, easily accessible patient risk factor data base.
