Abstract
The relationships of blood glucose levels to symptoms and symptom beliefs were examined in this study of persons (N=51) with Type II diabetes. Analyses revealed that 88% of the subjects had at least one symptom that was substantially correlated with blood glucose levels. However, subjects' symptom beliefs (symptoms subjects believe are the best indicators of high or low blood glucose levels) were largely unrelated to actual blood glucose levels. Thus, subjects were often mistaken about which of their symptoms were accurate indicators of blood glucose levels. Analyses also showed that the accuracy of symptom beliefs for low blood glucose was positively related to metabolic control.
