Self-reported history of abnormal Pap smear is used in large public health surveys. However, literature on the accuracy of this reporting is limited. We sought to assess the validity of self-reported abnormal Pap history in a community-based sample of African-American women 24-37 years of age in the Detroit, MI, recruited from 2010 to 2012.
We compared self-reported data on 2-year history of abnormal Pap smear to medical Pap record data (the gold standard) obtained from eligible participants. Sensitivity and specificity were evaluated to summarize the accuracy of the self-reported data. We also explored the sensitivity by severity of abnormality.
We identified 345 participants with 480 eligible Pap records. Thirty-five percent of abnormal Pap results were not identified by self-report (sensitivity/specificity: 65%/91%; kappa = 0.54). The sensitivity of reporting an abnormal Pap tended to be higher for those with a more severe abnormality.
A large proportion of abnormal Pap smears were not identified by self-report in this sample of African-American women. Public health studies utilizing self-reported abnormal Pap information should be interpreted with caution.
在大型公共卫生调查中，常采用自我报告的巴氏涂片异常史。然而，关于这种报告的准确性的文献有限。我们试图在底特律 24-37 岁的非裔美国女性社区样本中评估自我报告的巴氏涂片异常史的准确性，该样本是在 2010 年至 2012 年招募的。
我们将两年内巴氏涂片异常史的自我报告数据与从合格参与者处获得的医学巴氏涂片记录数据（金标准）进行了比较。通过评估灵敏度和特异性来总结自我报告数据的准确性。我们还通过异常严重程度来探索灵敏度。
我们确定了 345 名参与者，其中有 480 份合格的巴氏涂片记录。自我报告未识别出 35%的巴氏涂片异常结果（灵敏度/特异性：65%/91%；kappa=0.54）。对于异常程度较重的人，报告巴氏涂片异常的灵敏度较高。
在这个非裔美国女性样本中，有很大比例的巴氏涂片异常未被自我报告识别。利用自我报告的巴氏涂片异常信息的公共卫生研究应谨慎解读。
