| Abstract A questionnaire was designed consisting of 7 main sections and a section entitled "Suggestions for improving brightness". The validity of the questionnaire was determined based on expert comments and the CVI index. Its reliability was assessed by completing the questionnaire by hospital staff. According to the North American Society of Lighting Engineers (IESNA) standard, illumination was evaluated and compared with the questionnaire results. The Cronbach's alpha coefficient and CVI value of the questionnaire were estimated to be 0.901 and 0.97, respectively. There was a significant positive relationship between the mean score of the questionnaire and the illuminances in the workstations (P = 0.001). 72.8% of the workstations had good lighting, and the results of the questionnaire evaluation in these stations showed good and excellent lighting conditions. |
