طراحی الگوی عوامل پیش بینی کننده کیفیت زندگی بیماران مبتلا به اولسر پپتیک بر اساس آنالیز مسیر سازه های مدل پرسید

 Background: Peptic Ulcer Disease (PUD) has a considerable impact on patients’ quality of life. So, the aim of this study was application of regression based path analysis for introduction of the best model of PUD quality of life determinants, using PRECEDE Model constructs. Methods: This cross sectional study was performed among 120 outpatient referee with PUD to Beasat Hospital in the city of Sanandaj in Iran. Study instrument included questionnaires regarding PRECEDE model constructs used to measure the variables. Reliability and validity of the instruments were examined and approved. Significant level was set at 0.05. Results: Study findings showed that health status had a direct effect on quality of life. Self-management behaviors had an indirect effect on quality of life and health status through reinforcing factors. Also, predisposing, reinforcing and enabling factors had an indirect effect on quality of life through health status. After health status, reinforcing factors was the second powerful predictor of quality of life in PUD patients and then predisposing factors was the third one. Conclusions: PRECEDE model can be used as a conceptual framework for designing and implementing educational intervention programs to promote quality of life in PUD patients. Reinforcing factors was found as the most powerful factor in the educational and ecological diagnostic stage of predictors of quality of life in PUD patients which need to be considered, carefully, while designing intervention programs.
