Symptom use and self-regulation in type II diabetes.

A model of self-regulation that explains the health behavior of type II diabetic patients was tested by examining the use of symptoms as indicators of perceived blood glucose levels in 38 outpatients. Results of the study supported the self-regulation model by demonstrating that patients use symptoms to monitor blood glucose levels and to guide diabetes-related actions. Implications of the model for planning interventions with type II diabetes are discussed.
