| Abstract: | A between-groups design using a baseline, treatment, follow-up procedure was used to investigate the accuracy of 20 patients with insulin-dependent diabetes when subjectively estimating their blood glucose levels. Patients were encouraged to attend to their mood for cues when making estimates of their blood glucose. Their capacity for reducing estimation errors when given immediate or delayed feedback of actual blood glucose was examined. The results showed that neither delayed nor immediate feedback produced a significant improvement in the mean estimation accuracy of these groups of patients or in their ability to predict whether their blood glucose was in the acceptable or unacceptable range. Patients were particularly inaccurate in detecting Low less than 4.0 mmol/L (less than 72.0 mg/dl)] and Very High greater than 16.0 mmol/L (greater than 288.0 mg/dl)] blood glucose levels. Examination of mood-blood glucose relationships revealed consistent patterns for individual subjects and considerable differences between subjects. |
