Background The Iowa Satisfaction with Anesthesia Scale (ISAS) is a valid and reliable measurement tool developed to evaluate patient satisfaction with anesthesia care during different surgical interventions. It is adapted to various languages and used in many studies. Considering the satisfaction of the patient with anesthesia applied in surgical procedures, the presence of such a measurement tool is crucial. Aim From this point of view, the study aimed to evaluate psychometric properties of the ISAS by adapting it to Turkish culture. Methods In this study, a descriptive, methodological and cross-sectional design was used. A total of 210 patients who underwent surgery under general or regional anesthesia were in the study. Results ISAS Turkish version (ISAS-T) shows good reliability which is obvious with a Cronbach’s alpha value of 0.80. The correlation levels of the items with the ISAS total score were calculated between .45 and .73. Test–retest reliability was calculated as 0.83. CFA analysis was applied to the one-dimensional 11-item final version of ISAS. The uni-dimensionality of the 11-item scale was confirmed on a Turkish patient sample. The fit indices for the model obtained were calculated as χ 2 /sd = 2.342, RMSEA = .80, SRMR = .04, CFI = .90, GFI = .92. The fit indices of the model have good and acceptable fit values. Conclusion Based on the psychometric evaluation, ISAS-T is a valid and reliable measurement tool for measuring patient satisfaction with anesthesia applied during different surgical procedures.
