To assess the validity of self-reported illnesses, medical records were reviewed for participants reporting major illnesses on the biennial follow-up questionnaires used in a prospective cohort study which began in 1976. In over 90% of cases of cancer of the breast, skin, large bowel, and thyroid, histopathology reports confirmed the subjects' self-report. Lower levels of confirmation were obtained for cancers of the lung, ovary, and uterus. Application of strict diagnostic criteria also gave lower levels of confirmation for myocardial infarction (68%) and stroke (66%). Among random samples of women reporting fractures and hypertension all records obtained confirmed self-reports. For self-reported elevated cholesterol levels 85.7% of self-reports were confirmed. Self-report is a valuable epidemiologic tool but may require additional documentation when the disease is diagnostically complex.
为评估自我报告疾病的有效性，对一项始于1976年的前瞻性队列研究中每两年进行一次随访问卷调查时报告患有重大疾病的参与者的病历进行了审查。在乳腺癌、皮肤癌、大肠癌和甲状腺癌病例中，超过90%的组织病理学报告证实了受试者的自我报告。肺癌、卵巢癌和子宫癌的证实率较低。采用严格的诊断标准时，心肌梗死（68%）和中风（66%）的证实率也较低。在报告骨折和高血压的女性随机样本中，所有获取的记录均证实了自我报告。对于自我报告的胆固醇水平升高，85.7%的自我报告得到了证实。自我报告是一种有价值的流行病学工具，但在疾病诊断复杂时可能需要额外的文件证明。
