糖尿病患者和医疗从业者通常都认为极低和极高血糖(BG)水平的主观症状很容易识别。这项研究测试了26名胰岛素依赖型糖尿病患者BG症状信念的准确性。受试者内部的重复测量设计被用来确定与个别受试者的低血糖和高血糖水平相关的症状。在一年的时间里，受试者有三次在40次连续的血糖自我测量之前完成了症状清单(平均每天四次，持续10天)。在年底，受试者报告了他们认为哪些症状与他们自己的低血糖和高血糖水平有关。在确定每个核对表项目是否(A)经验性地与血糖水平相关以及(B)被认为与血糖水平相关后，症状信念被归类为命中、错误警报、未命中或正确拒绝。在受试者中，准确信念(命中和正确拒绝)的频率高于不准确信念(错误警报和未命中)的频率。然而，症状信念的准确性对不同的受试者有很大的不同，每个受试者至少有一个不准确的信念。错误的警报信念是更常见的错误类型。女性受试者的症状信念会产生更多的命中，也会产生更多的错误警报。男性比女性漏掉了更多的症状，特别是低血糖症状。如果症状-血糖关系随着时间的推移保持稳定，症状信念的准确性就会更高。
Both diabetic patients and health care practitioners often assume that the subjective symptoms of extreme low and high blood glucose (BG) levels are easily recognized. This study tested the accuracy of BG symptom beliefs in a group of 26 insulin-dependent diabetic patients. A within-subject, repeated measures design was used to identify symptoms related to low and high glucose levels for individual subjects. On three occasions over a 1-year period, subjects completed symptom checklists just prior to 40 consecutive self-measurements of BG (an average of four times per day for 10 days). At the end of the year, subjects reported which symptoms they believed were related to their own low and high glucose levels. After determining whether each checklist item was (a) empirically related to glucose levels and (b) believed to relate to glucose levels, symptom beliefs were categorized as hits, false alarms, misses, or correct rejections. Across subjects, the frequency of accurate beliefs (hits and correct rejections) was higher than the frequency of inaccurate beliefs (false alarms and misses). Symptom belief accuracy differed greatly for individual subjects, however, and every subject had at least one inaccurate belief. False alarm beliefs were the more common type of error. Female subjects’ symptom beliefs yielded more hits, as well as more false alarms. Males missed more symptoms, especially low BG symptoms, than females. Symptom belief accuracy was greater if symptom-glucose relationships remained stable across time.
