This research aims to investigate the structural relationships between inpatient satisfaction and service quality dimensions. To that end, a multidimensional model was developed and empirically validated. Exploratory factor analysis, confirmatory factor analysis, and structural equation modelling were applied to specify the relationships between service quality dimensions and satisfaction. Results indicated that the general causal relationship between service quality and inpatient satisfaction was well supported in the Iranian health care delivery system. The research identified twenty-two items driving four primary dimensions which were positively related to patient satisfaction. The primary dimensions were interpersonal relationship, administrative processes, amenities, and physician care.
