Objective To translate and test the reliability and validity of Nurse Intuition Patient Deterioration Scale（NIPDS），and to verify the predictive role of the scale in emergency patients’ deterioration. Methods The Brislin translation method was used to translate the NIPDS literally，back-translate and cross-culturally adjust to the Chinese version of the NIPDS. A total of 232 patients admitted to the emergency department were conveniently selected，and NIPDS registration was performed when the on-duty nurse intuited the deterioration of the patient’s condition，so as to evaluate the reliability and validity of the scale. Results The Chinese version of Nurse Intuition Patient Deterioration Scale was a single dimension scale with 9 items in total. The total Cronbach’s α coefficient was 0.891，and the broken half reliability was 0.848. The content validity of the scale was 0.920，the item content validity was 0.840~1.000，and the cumulative variance contribution rate was 54.305%. Standardized factor load coefficient was 0.544~0.790. When area under the receiver operating characteristic（ROC） curve was 0.753（95%CI =0.656~0.850，P<0.001），truncation value was 6 points，Youden index was 0.483，sensitivity was 0.622，specificity was 0.861，and scale validity was good. Rasch model analysis showed that the item reliability and sample reliability are 0.980 and 0.770 respectively，the item difficulty load ranges from -2.534 to 1.439，and the item difficulty was suitable. Conclusion The Chinese version of NIPDS has good reliability and validity，and is an effective and accurate tool，which can be used as an auxiliary supplement to the existing early warning system to help nurses make early judgment on the deterioration of emergency patients.
