癌症筛查研究依赖于对癌症筛查行为的可靠和有效的测量。筛查的自我报告构成了衡量筛查行为的一种经济有效的方法；然而，证明这些自我报告的适当有效性是至关重要的。我们评估了自我报告的重复、常规、年度经阴道超声(TVS)筛查卵巢癌的有效性。在一项以大学为基础的卵巢癌筛查计划中，参与者(n=)在最初的基线TVS筛查测试18个月后完成了电话采访。获得了自基线以来重复常规卵巢癌筛查试验的自我报告，并与筛查计划数据库中重复筛查的客观记录进行了比较。卵巢癌筛查自我报告与客观记录的总体符合率为97.57%(κ=0.94)。敏感性为0.98，特异性为0.96，阳性预测值为0.98，阴性预测值为0.96。80%的参与者准确地确定了最后一个月的筛查时间。结论是，TVS筛查卵巢癌的自我报告的效度非常高，甚至可能超过类似回忆时期参与乳腺癌、宫颈癌和结直肠癌筛查的自我报告的效度。因此，TVS筛查的自我报告可以作为评估TVS筛查行为的更客观方法的经济有效的替代品。(癌症流行病学生物标记物2007；16(3)：490-3)
Cancer screening research relies on reliable and valid measurement of cancer screening behavior. Self-reports of screening constitute a cost-effective approach to measuring screening behavior; however, demonstration of suitable validity of these self-reports is critical. We evaluated the validity of self-report of return for repeat, routine, annual transvaginal sonography (TVS) screening for ovarian cancer. Participants (n= 535) in a university-based ovarian cancer screening program for asymptomatic, average risk women completed a telephone interview 18 months following an initial, baseline TVS screening test. Self-reports of return for a repeat, routine ovarian cancer screening test since baseline were obtained and compared with objective records of repeat screening from the screening program database. Overall agreement of self-reports and objective records of ovarian cancer screening was 97.57% (κ= 0.94). Sensitivity was 0.98, specificity was 0.96, positive predictive value was 0.98, and negative predictive value was 0.96. The month of last screening was accurately identified by 80% of participants. It was concluded the validity of self-reports of TVS screening for ovarian cancer is very high and may even exceed the validity of self-reports of participation in breast, cervical, and colorectal cancer screening over similar recall periods. Consequently, self-reports of TVS screening may serve as a cost-effective substitute for more objective methods of assessing TVS screening behavior. (Cancer Epidemiol Biomarkers Prev 2007;16(3):490–3)
