VALIDATING WOMEN'S SELF REPORT OF MAMMOGRAM EXPERIENCE

许多卫生服务研究和癌症控制评估 将需要继续依靠患者自我报告的筛查 经验和了解这些自我报告的准确性是很重要的 是。乳腺癌筛查就是一个很好的例子。研究依赖于 自我报告，因为筛查乳房X光检查可能涉及与 几个不同站点的多个提供商，这使得很难 以传统方式(即病历审计)审查经验。 不仅评估者和研究人员需要记录筛选 参与(数量，周期)，但人们对文档的兴趣越来越大 成本和利用率(例如，随访、活组织检查) 放映。该项目有四个目标：a)确定 11种乳房X光检查相关测量方法的自我报告效度 与临床记录数据的比较；b)记录以下情况的程度 受访者的特征影响自我报告的准确性；c)比较 自我报告数据收集的两种方法：电话和邮寄调查； 和d)将选定的三项措施的校正系数应用于 独立的数据集。 这项研究的调查人员包括主要 大城市地区的放射科小组和初级保健医生 在马萨诸塞州西部。女性患者，年龄50-75岁，原发 医生将被邮寄到这项研究中来。在这些女性中 同意参与，一半将获得书面调查，一半将获得 电话采访。妇女提供的信息的准确性将 与放射学报告和医疗记录中的数据进行比较。 将使用回归技术来确定以下协变量 自我报告的准确性，如年龄、收入、健康史、医疗保健 使用和选定的心理社会测量以及准确度的衰减 增加了事件发生后的时间。将计算修正系数 随后与1,000人调查的现有数据集进行比较 女人。

Many health services research studies and cancer control evaluations will need to continue to rely on patient self-report of screening experience and it is important to know how accurate these self-reports are. Breast cancer screening is case in point. Studies depend on self-report because screening mammography may involve interaction with several providers at several different sites, making it difficult to review experience in the traditional manner (i.e. medical record audit). Not only do evaluators and researchers need to document screening participation (number, periodicity) but interest is mounting to document cost and utilization (e.g. follow-up, biopsy) which results from screening. This project has four objectives: a) to determine the validity of self-report of eleven mammography related measures by comparison to clinical records data; b) to document the extent to which respondent characteristics affect self-report accuracy; c) to compare two methods of self-report data collection: telephone and mail surveys; and d) to apply correction factors for three selected measures to an independent data set. Investigators in this study include representatives of the major radiology group and primary care physicians in a large metropolitan area in western Massachusetts. Female patients, ages 50-75, of primary physicians will be invited by mail into the study. Of the women who agree to participate, 1/2 will get a written survey and 1/2 will get a telephone interview. The accuracy of information provided by women will be compared to data taken from radiology reports and medical records. Regression techniques will be used to determine covariates of self-report accuracy, such as age, income, health history, medical care use and selected psychosocial measures as well as decay of accuracy with increasing time since the event. Correction factors will be calculated and subsequently compared to an existing data set from a survey of 1,000 Women.
