Polish adaptation of the Iowa Satisfaction with Anaesthesia Scale

Abstract

Introduction. The paper presents the adaptation of the Iowa Satisfaction with Anesthesia Scale to the conditions in Polish hospitals.Methods. The process of cultural adaptation of the Iowa Satisfaction with Anesthesia Scale was divided into three stages. The first stage was to formulate the Polish version of the ISAS. Secondly, the scale was used in the group of patients who were diagnosed with a maxillofacial injury and underwent surgical procedure. The final stage evaluated the psychometric features of the Polish version of the ISAS.Results. 195 questionnaires were completed correctly and they were subject to further analysis. The questionnaires were collected from patients residing at the Maxillofacial Surgery Clinical Ward who were operated under a general anaesthesia due to a maxillofacial trauma. The average result of the satisfaction with anaesthesia in a studied group was 0.77 (scale from -3 to +3) M=2, SD=2.41. The Cronbach’s alpha coefficient calculated for 11 multiple choice questions was 0.598. It would be possible to increase the Cronbach’s alpha coefficient if question no. 1 (I vomited or felt nauseous) was eliminated from the test (maximum 0.601). Every item on the scale had significant influence on the general result (p=0.0001).Conclusions. Polish version of the Iowa Satisfaction with Anesthesia Scale meets the criteria of the psychometric equivalence with the original version. It is necessary to continue research using Polish version of the ISAS to provide a constant verification of reliability and accuracy of the research tool.

Transcultural validation of a French version of the Iowa Satisfaction with Anesthesia Scale (ISAS-F)

“…[3][4][5] It is the only validated score to assess patient satisfaction after conscious intravenous sedation for surgery, 5,6 and its sensitivity to change has been used in a clinical trial of dexmedetomidine. 7 Validated Spanish and Polish versions are available, 8,9 and although a French version has been tested for ocular surgery, 10,11 this was only a simple direct translation and did not follow the recommended processes of a transcultural validation (see Methods) as recommended by the United States Food and Drug Administration 12 and the WHO. 13 The aim of this study was to validate a French version of the ISAS by analyzing construct validity, internal consistency, convergent validity, and test-retest reliability, in a sample of patients undergoing scheduled brief surgical procedures needing conscious sedation.…”
