This study reports on the development and psychometric testing of inpatient and ambulatory patient satisfaction scales designed to measure patient satisfaction using the standards of nursing practice within a medical center. The surveys were administered to patients 4-6 weeks after discharge from the hospital or following a clinic visit. A total of 619 inpatient and 955 ambulatory patient questionnaires were analyzed. Factor analyses suggest there exist four scales for inpatient satisfaction anf five scales for outpatient satisfaction with high reliability and reasonable validity.
