Development of instrument to measure perception of healing environment in hospital

Abstract

This study aimed to develop an instrument to measure perception of the healing environment in hospitals and examine its reliability and validity through literature review and interviews with experts. Cronbach’s alpha coefficient, item total correlation coefficient, and factor analysis were used to test validity and reliability of the instrument in a total of 551 nurses. Cronbach’s alpha was .955 for 30 items in total and the KMO value (.930) and Bartlett's test of sphericity (χ2=4434.611, p<.001) suggested statistical significance. Six factors were drawn, with the total accumulated variate at 68.40%; Factor 1 accounted for 16.82%, Factor 2 15.70%, Factor 3 13.57%, Factor 4 8.48%, Factor 5 7.78%, and Factor 6 6.03%. On the basis of the results, the instrument to measure perception of the healing environment is reliable and valid and is expected to be useful in measuring perception of the healing environment in hospitals
