title: Analysis of some predictive factors of quality of life among type 2 diabetic patients.
abstract: BACKGROUND
  Considering the chronic nature of diabetes and its significant effect on quality of life of patients, the present study was conducted to evaluate predictors of quality of life in these patients in order to facilitate planning health promotion intervention programs.
  
  
  METHODS
  The present study was designed as a cross-sectional study on 140 type 2 diabetic patients of Om-ol-Banin Diabetes Center of Isfahan. Data collection tool was a multidimensional questionnaire including demographic and disease related data (12 items), the standard scale for diabetes distress (17 items), the standard scale for self-efficacy in diabetic patients (8 items), and standard scale for specific quality of life of diabetic patients (15 items). Collected data were evaluated by SPSS version 11.5 using the Chi-square test, Independent T-test, ANOVA, Pearson correlation and multivariate regression analysis.
  
  
  RESULTS
  Results showed that the quality of life of diabetic patients had a statistically significant correlation with diabetes distress variable (P < 0.001) and self-efficacy variable (P < 0.001). In this study R(2) (predictive power) was 0.66. Multivariate regression model indicated diabetes distress (β = -0.277, P = 0.01) and self-efficacy (β = -0.161, P < 0.001) as variables influencing adjusted self-management for other variables.
  
  
  CONCLUSIONS
  The result of the present study urges that in planning health promotion interventions in the field of diabetes, more attention be paid to self-efficacy and diabetes distress variables in order to improve the efficiency and effectiveness of the interventions carried out.
