Psychometric properties of an instrument to measure nursing students' quality of life.

It is important for clinical nursing teachers and managers to recognize the importance of nursing students' quality of life (QOL) since they are the source of future nurses. As yet, there is no quality of life evaluation scale (QOLES) specific to them. This study designed a quantitative instrument for evaluating QOL of nursing students. The study design was a descriptive survey with mixed methods including literature review, panel discussion, Delphi method, and statistical analysis. The data were collected from 880 nursing students from four teaching hospitals in Wuhan, China. The reliability and validity of the scale were tested through completion of the QOLES in a cluster sampling method. The total scale included 18 items in three domains: physical, psychological, and social functional. The cumulative contributing rate of the three common factors was 65.23%. Cronbach's alpha coefficient of the scale was 0.82. This scale had good reliability and validity to evaluate nursing students' QOL.
