作者进行了一项基于社区的胆固醇筛选研究，以检验在长期自传体记忆中回忆自我相关健康信息的准确性。成年社区居民(N=496)被招募参加以实验室为基础的胆固醇筛查，并根据国家指南提供胆固醇咨询。参与者随后在1个月、3个月或6个月后接受采访，以评估他们对测试结果的记忆。参与者回忆起他们确切的胆固醇水平不准确(38.0%正确)，但他们的心血管风险类别相对较好(88.7%正确)。回忆错误显示了一种系统性的偏差：收到最不受欢迎的测试结果的人最有可能记住他们的胆固醇得分和心血管风险类别比实际收到的低(即，更健康)。回忆偏差与年龄、教育、知识、自我评估的健康状况和自我报告的降低胆固醇的努力无关。这些发现提供了证据，表明对自我相关健康信息的回忆容易受到自我提升偏见的影响。
The authors conducted a community-based cholesterol screening study to examine accuracy of recall for self-relevant health information in long-term autobiographical memory. Adult community residents (N = 496) were recruited to participate in a laboratory-based cholesterol screening and were also provided cholesterol counseling in accordance with national guidelines. Participants were subsequently interviewed 1, 3, or 6 months later to assess their memory for their test results. Participants recalled their exact cholesterol levels inaccurately (38.0% correct) but their cardiovascular risk category comparatively well (88.7% correct). Recall errors showed a systematic bias: Individuals who received the most undesirable test results were most likely to remember their cholesterol scores and cardiovascular risk categories as lower (i.e., healthier) than those actually received. Recall bias was unrelated to age, education, knowledge, self-rated health status, and self-reported efforts to reduce cholesterol. The findings provide evidence that recall of self-relevant health information is susceptible to self-enhancement bias.
