有效和可靠的癌症筛查行为自我报告措施对于评估改善对指南的遵从性的努力非常重要。我们使用国家癌症研究所结直肠癌筛查(CRCS)问卷评估了粪便潜血试验(FOBT)、乙状结肠镜检查(SIG)、结肠镜检查(COL)和钡灌肠检查(BE)自我报告的重测信度和效度。第二个目标是通过邮件、电话和面对面的调查管理模式来评估可靠性和有效性。同意的男性和女性，年龄在51到74岁，在多科诊所接受至少5年的护理，没有被诊断为结直肠癌，根据既往的结直肠癌状况进行分层，并随机进入调查模式(n=857)。在调查模式中，受访者被随机安排在2周、3个月或6个月完成第二次调查。将自我报告与行政和医疗记录相比较，一致性估计为COL为0.91，FOBT为0.85，SIG为0.85，BE为0.92。总体敏感性估计为COL为0.91，FOBT为0.82，SIG为0.76，BE为0.56。特异性估计COL为0.91，FOBT为0.86，SIG为0.89，BE为0.97。对于任何测试，敏感度和特异度几乎不因调查方式而异。报告与记录比率显示SIG(1.1)、COL(1.15)和FOBT(1.57)多报，而BE(0.82)少报。COL在所有时间间隔的可靠性最高；根据调查模式，没有一致的模式。这项研究提供了证据，支持使用国家癌症研究所CRCS问卷来评估三种调查模式中的任何一种的自我报告。
Valid and reliable self-report measures of cancer screening behaviors are important for evaluating efforts to improve adherence to guidelines. We evaluated test-retest reliability and validity of self-report of the fecal occult blood test (FOBT), sigmoidoscopy (SIG), colonoscopy (COL), and barium enema (BE) using the National Cancer Institute colorectal cancer screening (CRCS) questionnaire. A secondary objective was to evaluate reliability and validity by mail, telephone, and face-to-face survey administration modes. Consenting men and women, 51 to 74 years old, receiving care at a multispecialty clinic for at least 5 years who had not been diagnosed with colorectal cancer were stratified by prior CRCS status and randomized to survey mode (n = 857). Within survey mode, respondents were randomized to complete a second survey at 2 weeks, 3 months, or 6 months. Comparing self-report with administrative and medical records, concordance estimates were 0.91 for COL, 0.85 for FOBT, 0.85 for SIG, and 0.92 for BE. Overall sensitivity estimates were 0.91 for COL, 0.82 for FOBT, 0.76 for SIG, and 0.56 for BE. Specificity estimates were 0.91 for COL, 0.86 for FOBT, 0.89 for SIG, and 0.97 for BE. Sensitivity and specificity varied little by survey mode for any test. Report-to-records ratio showed overreporting for SIG (1.1), COL (1.15), and FOBT (1.57), and underreporting for BE (0.82). Reliability at all time intervals was highest for COL; there was no consistent pattern according to survey mode. This study provides evidence to support the use of the National Cancer Institute CRCS questionnaire to assess self-report with any of the three survey modes.
