Cultural adaptation and psychometric evaluation of the Polish version of the Newcastle Satisfaction with Nursing Scale

Introduction The paper presents the methods of cultural adaptation of the Newcastle Satisfaction with Nursing Scale (NSNS) to the conditions in Polish hospitals. Material and methods The process of cultural adaptation of the research tool took into consideration an analysis of different equivalence levels, the translation procedure and the estimation of psychometric parameters. The Polish version of the NSNS questionnaire was correctly completed by 787 patients making up 59.36% of the total number of patients who received the scale. Results The Polish version of the NSNS questionnaire was correctly completed by 787 patients making up 59.36% of the total number of patients who received the scale. Cronbachs α coefficient was 0.921 for the “experience” scale and 0.981 for the “satisfaction” scale. The values of Spearmans rank correlation coefficient were from 0.224 to 0.797 for “experience” and 0.815–0.894 for “satisfaction”. All questionnaire items of the Polish NSNS version exerted a statistically significant influence on the total results of the scale (p = 0.0001). Conclusions The Polish NSNS version, similarly as the original version, can identify differences referring to “experience” and “satisfaction” with nursing care between the particular departments and between hospitals. The Polish NSNS version was conducted among patients during multicentre studies and it meets the criteria of functional, psychometric and façade equivalences.

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.
