Background and Objectives : Measurement of patient satisfaction to general anesthesia needs
a valid and reliable tool to cover all dimensions of satisfaction. However, there is no standard tool in a
Thai version for measurement of this satisfaction. The objective of this study was to develop a valid
and reliable tool for measurement of patient satisfaction to general anesthesia.
Method: Review of the medical literature and patients' interviews were performed to generate
the ideas and dimensions of satisfaction. Items were generated according to customer satisfaction.
The pilot questionnaire was set and verified for content validity by item correlation. One item
of low item correlation was deleted. The pilot study was performed by application of the pilot ques-
tionnaire to patients to detect problems on processes to derive responses and problems of the ques-
tionnaire. Another two items were excluded due to high missing responses. The results of reliability
analysis were satisfactory. Revision of the pilot questionnaire was taken eventually into the final ques-
tionnaire. Then, the final questionnaire was processed to obtain Cronbach' s alpha coefficient at King
Chulalongkom Memorial Hospital. Finally, retest for reliability was taken at Police General Hospital
in order to prove its generalization.
Results : The constructed final questionnaire composed of ten items. All item correlations
were higher than 0.5. Cronbach's alpha coefficients obtained in King Chulalongkom Memorial Hos-
pital and Police General Hospital were 0.8775 and 0.7571, respectively.
Conclusion: The developed questionnaire was qualified for both validity and reliability. Also
verified for the wide application in another hospital.
