Reliability and validity of Chinese version of the nurses self-concept instrument in nursing undergraduates

ObjectiveTo translate the nurses self-concept instrument (NSCI) to form the Chinese version of NSCI, and assess the reliability and validity of the scale in nursing undergraduates.

MethodsAfter literally and back translating the NSCI, the Chinese version of NSCI was formed through cultural adjustment and revision.A total of 1 284 nursing undergraduates were tested collectively, and the validity of the scale was tested using the professional self-concept of nurse instrument as criterion.Two weeks later, one hundred and twenty-six nursing undergraduates were selected for retest.

ResultsThree factors including care, staff relation and leadership were contained in the Chinese version of NSCI, which explained 67.11% of the total variance, and the scale was significantly positively correlated with the criterion scale (r=0.698-0.848, P < 0.01).The confirmatory factor analysis ascertained the three-factor model.The internal consistency of the Chinese version of NSCI was 0.742-0.918, and the retest reliability was 0.736-0.943.

ConclusionsThe Chinese version of NSCI has good reliability and validity, and can be used to evaluate the professional self-concept of nursing undergraduates.
