c) The ONS Knowledge, Attitude and Action Questionnaire for Oncology Nurses has good reliability and validity Reliability reflects the consistency of evaluation tools, that is, whether the evaluation tools can stably evaluate the measured variables. The overall Cronbach's α coefficient of the questionnaire prepared in this study was 0.958, and the Cronbach's α coefficient of each dimension was 0.862-0.972, all >0.80, indicating that the questionnaire had good internal consistency. The test-retest reliability of this study was 0.978, and the test- retest reliability of each dimension was 0.761-0.985, all >0.70, indicating that the questionnaire has good stability and consistency across time. Validity refers to the degree to which the assessment tool reflects the expected research concept, that is, the correctness and validity of the questionnaire [12]. After 2 rounds of exploratory factor analysis, this study extracted 5 common factors, the cumulative variance contribution rate was greater than 40%, and the factor loading of each item was greater than 0.4, indicating that the questionnaire was basically consistent with the theoretical structure of the questionnaire; the confirmatory factor analysis results showed that , x2/df < 5.00, RMSEA < 0.10, IFI, CFI, GFI are > 0.90, PCFI, PNFI are > 0.50, all fitting indicators are in the acceptable range, indicating that the model fits well. The above results show that the questionnaire has good construct validity. The overall S-CVI of the questionnaire in this study is 0.914, the S-CVI of each dimension is 0.903-0.925, all > 0.90; the I-CVI of each item is 0.832- 1.000, all > 0.78, indicating that the content of this questionnaire can reflect the The current status of ONS knowledge, belief, and behavior among nurses in the oncology department has good content validity. IV. C onclusion The ONS knowledge, belief, and behavior questionnaire for oncology nurses prepared in this study has good reliability and validity. It can be used as a scientific tool to assess the current status of ONS knowledge, belief, and behavior of oncology nurses, and provides a theoretical basis for carrying out targeted training programs and formulating scientific management strategies. Due to limited conditions, this study only investigated five tertiary first-class hospitals in Jiangsu Province, and the generalizability of the questionnaire was limited. In the future, the sample size will be increased and expanded to hospitals in multiple regions and levels to further verify and improve the questionnaire.
