Introduction and purpose: Hemodialysis, as the most common renal replacement therapy in renal patients, leads to a variety of physical and psychological problems. Therefore, the aim of this study was to determine structural equation modeling of adherence to treatment based on personality traits mediated by locus of control in hemodialysis patients. Methods: The research method was descriptive and correlation research design was structural equation model. The statistical population of this study was all chronic kidney patients undergoing hemodialysis in Tehran in 2018, among whom 200 patients were selected by available sampling method. Data were collected using adherence to treatment scale, neo-personality questionnaire, and health locus of control questionnaire. To analyze the research data, correlation coefficient-Pearson and path analysis and SPSS.22 and AMOS.22 softwares were used. Results: The results showed that neuroticism (p=0.029), openness (p=0.031), conscientiousness (p=0.003), significant other locus of control (p=0.003) and internal locus of control (P=0.039) had a direct effect on adherence to treatment. The results also showed that the source of health control plays a mediating role in the relationship between personality traits and adherence to treatment. Conclusion: It can be concluded that the locus of control among patients undergoing hemodialysis mediates the relationship between neuroticism, conscientiousness and extraversion and adherence to treatment.
