To assess the reliability and validity of self-reported attendance for mammographic screening.
To assess reliability of recall of attendance for a screening mammogram, 100 women selected at random were interviewed twice (approximately one week apart). To assess validity, 127 women who reported having a mammogram within the national breast screening program (BreastScreen Australia) consented to having their reports verified by the national program.
Test-retest reliability for the question "Have you ever had a mammogram?" was perfect (agreement 100%, kappa 1). Validity was also high. About one-quarter of women (24.4%) recalled the exact date of their last mammogram and a further third (39.4%) correctly reported the month in which the mammogram was done. Almost all (91.3%) women reported the mammogram date accurately to within 12 months of the recorded date.
These data suggest that Australian women provide reliable and valid information in relation to mammographic screening attendance.
Self-reported data about attendance for mammographic screening are likely to provide reliable and valid estimates for research and health services evaluation purposes.
评估自我报告的乳腺钼靶筛查参与情况的可靠性和有效性。
为评估乳腺钼靶筛查参与情况回忆的可靠性，随机选取100名女性进行两次访谈（间隔约一周）。为评估有效性，127名报告在国家乳腺筛查项目（澳大利亚乳腺筛查项目）中进行过乳腺钼靶检查的女性同意由该国家项目核实其报告。
对于“你做过乳腺钼靶检查吗？”这一问题，重测信度完美（一致性为100%，kappa值为1）。效度也很高。约四分之一的女性（24.4%）回忆起了她们上次乳腺钼靶检查的准确日期，另有三分之一（39.4%）正确报告了进行乳腺钼靶检查的月份。几乎所有女性（91.3%）报告的钼靶检查日期与记录日期相差在12个月内。
这些数据表明，澳大利亚女性在乳腺钼靶筛查参与情况方面提供了可靠且有效的信息。
关于乳腺钼靶筛查参与情况的自我报告数据可能为研究和卫生服务评估提供可靠且有效的估计。
