title: How diabetic patients' ideas of illness course affect non-adherent behaviour: a qualitative study.
abstract: BACKGROUND
  Type 2 diabetes is becoming more prevalent and its successful management relies on patients' self-care behaviours. Measures focusing on patients' perceptions can be effective behavioural interventions.
  
  
  OBJECTIVE
  To gain insight into the perceptions of patients with diabetes, especially ideas of the illness course and perceived severity, and their impacts on self-care behaviour.
  
  
  METHODS
  Qualitative approach with in-depth patient interviews (n = 22) and seven focus groups (n = 53).
  
  
  METHODS
  A rural town in Taiwan.
  
  
  METHODS
  The interview protocol was mainly derived from Kleinman's explanatory model. Purposive sampling strategies of maximum variation were used. The transcript of the interviews was analysed with editing and immersion/crystallisation styles.
  
  
  RESULTS
  Diabetes is regarded as an incurable, inevitably deteriorating disorder of sugar metabolism with many chronic complications. Patients thought that renal injury, followed by blindness, leg amputation, and poor peripheral circulation, were the most frequent complications. They also assessed their perceived severity of the disease at specific points in time through different indicators in their daily lives, such as sugar level, presence of complications, and medications used. Patients felt that these aspects progressed concurrently and that the illness course followed a unidimensional process. The ever-increasing doses of medication was considered by these patients to be a side-effect of the drugs taken.
  
  
  CONCLUSIONS
  Physicians should clarify with their patients that the risks of uraemia, blindness, and leg amputation are less prevalent than expected and that patients should pay more attention to cardiovascular complications. Certain oral hypoglycaemic agents may not cause a vicious cycle of ever-increasing doses of medication and the drugs that need to be taken should not be seen as indicators of severity but, rather, measures taken to prevent the diabetes becoming severe in the future.
