OBJECTIVES
To determine the accuracy of self-reported mammography use and generate a correction factor that adjusts for reporting errors among Mexican-American women.
DESIGN
Self-reported mammography use was compared with a medical chart review.
PARTICIPANTS
A random sample of 199 Mexican-American women aged 50-74 in southeast Texas.
MAIN OUTCOME MEASURES
Self-reported mammography use for the preceding 2 years and mammography use determined by medical chart review.
RESULTS
Positive and negative predictive values of mammography self-reports in the previous 2 years were 73.9 and 86.0%, respectively. The correction factor was 79.6%, or approximately 80% of the self-reported mammograms within the preceding 2 years could be verified through medical chart reviews.
CONCLUSIONS
Mammography use rates among Mexican-American women were not as high as self-reports indicated. Estimates need to be adjusted downward by approximately 20%.
目的
确定自我报告的乳房X光检查使用率的准确性，并生成一个校正因子，以调整墨西哥裔美国女性报告误差。
设计
将自我报告的乳房X光检查使用率与病历审查结果进行比较。
参与者
德克萨斯州东南部199名年龄在50 - 74岁之间的墨西哥裔美国女性的随机样本。
主要观察指标
过去两年自我报告的乳房X光检查使用率以及通过病历审查确定的乳房X光检查使用率。
结果
过去两年乳房X光检查自我报告的阳性预测值和阴性预测值分别为73.9%和86.0%。校正因子为79.6%，即过去两年内自我报告的乳房X光检查中约80%可通过病历审查得到证实。
结论
墨西哥裔美国女性的乳房X光检查使用率不如自我报告显示的那么高。估计值需要向下调整约20%。
