Reliability and validity of Chinese version of Moral Distress Scale / 中国实用护理杂志

ABSTRACT

Objective To translate Moral Distress Scale(MDS-R), and to test the reliability and validity of the Chinese version of MDS-R. Methods The MDS-R was translated, back translation and adapted according to Chinese culture. The reliability and validity of Chinese version of MDS-R was tested in 750 nurses in Quzhou city by item correlation analysis, content validity, exploratory factor analysis, confirmatory factor analysis, Cronbach′s Alpha coefficient and test-retest reliability. Results The internal consistency coefficient of the Chinese version of MDS-R ranged from 0.119-0.756 (P<0.01). The content validity was 0.952. validity.Factor analysis extracted three common factors, which explained 64.537％ of variance of the total scale. Based on the exploratory factor analysis, a theoretical model was established for the scale and each factor, and the fitting degree of the theoretical model was verified by the data. After fitting the model, the fitness values of the first and the second order confirmatory factor analysis were all up to the standard level. The Cronbach's Alpha coefficient of the scale was 0.925, and the test-retest reliability was 0.900. Conclusions The Chinese version of MDS-R is reliable and valid, and can be used to measure the moral distress of nurses.
