The reliability and validity of the inpatient satisfaction questionnaire as an instrument for measuring inpatient satisfaction

Objective: To assess the reliability and validity of the Inpotient Satisfaction Questionnaire (IPSQ) on the basis of a pilot survey. Methods: The subjects were 900 patients discharged from 3 general hospitals in Guangzhou. Mail survey was employed. The reliability was evaluated by internal consistency and test-retest reliability. The validity was assessed by content validity and construct validity. Results: The response rates were 30% for the test, 47% for the retest and 93.2% for the total items. High haiability of IPSQ was proved by Cronbach's a of 0. 92, and no sighficant difference (P = 0. 183) and whereas conspicuous correlation (r = 0. 812, P < 0. 000 1 ) between test and retest were shown. Content validity was supported by factor loading. Convergent and discriminant validity was strongly supported by the fact that the maximum interscale correlation was less than the internal consistency of individual dimension. Conclusion:The IPSQ was reliable and valid.
