structural equation modeling of treatment adherence based on general health and demographic characteristics in patients undergoing hemodialysis

Background: a complete adherence to treatment is essential for patients undergoing hemodialysis treatment. this health behavior is the product of various overlapping variables that may change over time. objectives: this study aimed to investigate treatment adherence based on general health and demographic characteristics among hemodialysis patients. methods: this was a descriptive-correlation research conducted based on structural equation modeling. the population included all patients with chronic kidney disease in tehran, iran, of whom 200 patients undergoing hemodialysis admitted to 2 medical centers from september to march 2022 were selected by convenience sampling. the data were collected using the general health questionnaire (ghq) and end-stage renal disease adherence questionnaire (esrd-aq). the data were analyzed using correlation analysis and path analysis in spss v. 19 and smartpls v. 3. results: the results showed the direct and significant effect of general health (p = 0.001) and age (p = 0.017) on treatment adherence. however, sex, marital status, level of education, and duration of dialysis treatment had no significant effect on treatment adherence. conclusions: considering the power of general health and age in predicting treatment adherence, these two variables can be included in training, clinical, and psychological interventions.
