Accuracy of recall of hip fracture, heart attack, and cancer was evaluated by comparing data obtained from postal surveys and medical records of participants in the Leisure World Disease Prevention Study. The study cohort comprised 13,897 residents of Leisure World Laguna Hills who responded to a questionnaire first mailed in 1981. Follow-up questionnaires requesting information on recent disease history were mailed in 1983 and 1985 to all living cohort members and were returned by 9,734 (86%) and 8,884 (82%) persons, respectively. The proportion of false-positive answers was about 40% for acute myocardial infarction, but less than 10% for hip fracture and cancer. Many of those who gave a false-positive answer on the questionnaire had a condition that the lay population might easily confuse with the condition of interest (e.g., heart attack vs. other cardiovascular disease). Among persons with the disease of interest recorded in the medical record, the percentage who failed to report their events on the questionnaires was highest for those who had an acute myocardial infarction, followed by those who had cancer and those who had hip fracture. The highest rates of confirmation of cancer were for cancers of the breast, bladder, prostate, and uterus. For closely related sites (e.g., colon and rectum), the reliability of reports decreased. The amount of information obtained varied according to the wording of the questionnaire and the specificity of the questions asked. Improved accuracy of recall was observed when the occurrence of specific diseases was asked in addition to a general question about recent hospitalizations.
通过比较从邮政调查和休闲世界疾病预防研究参与者的医疗记录中获得的数据，评估了髋部骨折、心脏病发作和癌症的回忆准确性。该研究队列包括13897名休闲世界拉古纳希尔斯的居民，他们对1981年首次邮寄的问卷做出了回应。1983年和1985年向所有在世的队列成员邮寄了要求提供近期疾病史信息的随访问卷，分别有9734人（86%）和8884人（82%）回复。急性心肌梗死的假阳性回答比例约为40%，但髋部骨折和癌症的假阳性回答比例不到10%。许多在问卷上给出假阳性回答的人所患疾病，普通人群可能很容易与感兴趣的疾病混淆（例如，心脏病发作与其他心血管疾病）。在医疗记录中记录有感兴趣疾病的人群中，问卷上未报告其患病情况的比例，急性心肌梗死患者最高，其次是癌症患者和髋部骨折患者。癌症确诊率最高的是乳腺癌、膀胱癌、前列腺癌和子宫癌。对于密切相关的部位（如结肠和直肠），报告的可靠性下降。根据问卷的措辞和所提问题的特异性，获得的信息量有所不同。当除了关于近期住院情况的一般问题外，还询问特定疾病的发生情况时，回忆准确性有所提高。
