Abstract:Objective To translate the English version of the Missed Nursing Care in Infection Prevention and Control (MNCIPC) Survey into Chinese, and to provide an effective measurement tool for evaluating nurses′ missed care in nosocomial infection prevention and control activities. Methods The English version of the scale was translated according to the Brislin principle. Cultural adjustment was performed through expert consultations and pre-tests, and 450 nurses were selected by convenient sampling method to conduct a questionnaire survey.The reliability and validity of the questionnaire were tested based on classical test theory (CTT) and Rasch model of item response theory (IRT). Results The Chinese version MNCIPC Survey contains two subscales:subscale B (31 items,measuring types and frequency of missed care) and subscale C (20 items, measuring reasons for missed care).The Cronbach′s α coefficient was 0.973 and 0.902, the test-retest reliability coefficient was 0.917 and 0.957, the scale-level content validity index (S-CVI) was 0.973 and 0.949, respectively for subscale B and C.Principal component analysis of residuals in Rasch model showed that the subscale B was unidimensional, and subscale C was non-unidimensional, though its four dimensions met the unidimensio-nal criteria.The item reliability coefficient was 0.97 and 0.98, and the separation index was 5.27 and 7.20 respectively for subscale B and C.The sample reliability coefficient was 0.85 and 0.88, and the separation index was 2.42 and 2.73 respectively for subscale B and C. Conclusion The Chinese version of the MNCIPC Survey has good reliability and validity, which can be used as a measurement tool to evaluate the current situation of missed nursing care and analyze the causes.
