This investigation presents the development of a scale designed to assess satisfaction with hospital health care services during hospital stays, based on an adaptation of a scale to measure satisfaction with primary health care services. We explored the factor structure and psychometric properties of the scale in a sample of 483 patients hospitalized in 8 hospital centres in Andalusia (Spain). We evaluated the level of satisfaction with the hospitalization stay to determine sex and age differences. The fit indices of confirmatory factor analysis are good and the internal consistency of both the sub-scales and the global measure were satisfactory. Although we did not find any sex differences, satisfaction differed as a function of age. As a main conclusion, the results suggest that this version of the scale is valid and reliable.
