title: The effects of education based on extended health belief model in type 2 diabetic patients: a randomized controlled trial.
abstract: BACKGROUND
  Type II diabetes and its complications impose a large economic burden on health care systems. This study aims to assess the effectiveness of educational intervention based on extended health belief model on type 2 diabetic patients.
  
  
  METHODS
  120 patients with type II diabetes referring to randomly selected hospitals of Tehran University of Medical Sciences were enrolled in this educational intervention study. Patients were randomly divided into two groups (intervention and control). Data were collected using a questionnaire including demographic information and extended health belief model constructs. Two face to face educational sessions were conducted for each patient. Data were collected in two groups at three stages of the study; before the educational sessions and at 3 months and 6 months intervals. Analysis was performed by SPSS (17.0) and STATA (11.0) using independent T-test, Chi-square, Fisher's exact test, analysis of covariance and Generalized Estimating Equation. A p value of less than 0.05 was regarded as statistically significant.
  
  
  RESULTS
  The educational program had a positive and significant impact (p < 0.0001) on extended health model belief constructs (including perceived susceptibility, perceived intensity, perceived benefits, perceived barriers and self-efficacy) in experimental group, 3 and 6 months after the intervention.
  
  
  CONCLUSIONS
  The results of this study showed the importance of extended health belief model based education in improving the model constructs and increasing self-efficacy in patients with type-2 diabetes.
