b. Confirmatory factor analysis The fitting results of the questionnaire model are: x2/df=3.494, RMSEA=0.098, IFI=0.914, CFI=0.914, PCFI=0.797, GFI=0.922, PNFI=0.753. ii. Content Validity The I-CVI of each item of the questionnaire was 0.832-1.000; the overall S-CVI of the questionnaire was 0.914; the S-CVI of the knowledge dimension, belief dimension and behavior dimension of the questionnaire were 0.903, 0.911 and 0.925, respectively. d) Reliability Analysis Results The Cronbach's alpha coefficients of the overall questionnaire, knowledge dimension, belief dimension and behavior dimension were 0.958, 0.862, 0.942 and 0.972, respectively; the test-retest reliability of the overall questionnaire, knowledge dimension, belief dimension and behavior dimension were 0.978, 0.761, 0.962, 0.985, respectively. e) Final Questionnaire of ONS Knowledge, Attitude and Practice of Oncology Nurses The final questionnaire consists of 43 items, including 8 items in the knowledge dimension, including 3 multiple-choice questions and 5 multiple-choice questions. A correct answer to a multiple-choice question is worth 1 point, a wrong answer is 0 points, and a multiple-choice question is answered correctly. 1 option Score 1 point, wrong answer is 0 point, the scoring range is 0~4 points; there are 13 items in the belief dimension, using Likert 5-point scoring method, "1~5 points" respectively means "strongly disagree" and "disagree" "Not sure", "agree", "strongly agree", the scoring range is 1-5 points; there are 22 items in the behavior dimension, using the Likert 5-point scoring method, "1-5 points" represent "never" and "occasionally" respectively "Sometimes", "Often" and "Always" on a scale of 1 to 5. The overall score of the questionnaire ranged from 35 to 198, with higher scores indicating better knowledge, beliefs and behaviors of ONS nurses. III. D iscussion a) It is of great significance to compile the ONS Knowledge, Attitude and Action Questionnaire for Oncology Nurses Rational nutritional support has significant benefits in remission, quality of life and prognosis of cancer patients [15]. ONS is a safe, convenient, cost- effective and effective nutritional treatment measure. The European society for clinical nutrition and metabolism (ESPEN)[16], the Chinese society for parenteral nutrition and enteral nutrition, CSPEN) [17] both recommend ONS as the first choice for nutritional therapy. The intake of ONS requires the active cooperation of patients, and its efficacy depends on the patient's compliance [7]. Nursing staff are the main contacts of patients during hospitalization and play a key role in the implementation and management of ONS. Expert consensus [5] pointed out that insufficient attention and non-standard implementation of ONS by nursing staff will reduce patients' compliance with ONS and affect the treatment effect. Nursing staff should be proficient in the implementation of ONS and translate it into practical actions, which is conducive to improving patients' compliance with ONS and enhancing its efficacy. Good behavior is based on correct knowledge and positive attitudes and beliefs [18]. Understanding the current status of oncology nurses' knowledge, beliefs, and behaviors about ONS can help improve their clinical execution. Therefore, it is very necessary to compile relevant questionnaires to provide a reliable evaluation tool for a comprehensive and objective understanding of oncology nurses' knowledge, belief, and behavior level of ONS, and to provide a basis for targeted training and management decisions. b) The scientific preparation process of the ONS questionnaire for oncology nurses Based on the theory of knowledge, belief, and action, this study constructed an initial item pool of the questionnaire according to relevant domestic and foreign literature, covering ONS pre-use assessment, scope of application, formulation selection, use risk assessment, efficacy evaluation, and health education. The relevant content of ONS is comprehensively included to ensure the standardization of the questionnaire items. This study adopts the Delphi method to invite clinical nursing, nursing management and nursing education experts with high academic level, solid theoretical foundation and rich clinical experience in the field of ONS to revise the initial item pool of the questionnaire; The recovery rate is 100%, and the authoritative coefficients of the experts in the two rounds of correspondence are 0.893 and 0.921 respectively, indicating that the experts have high enthusiasm and authority, and can make professional judgments and make valuable suggestions for each item, which ensures that the experts are highly motivated and authoritative. The rigor of the letter inquiry process and the reliability of the letter inquiry results; the research team revised and improved the questionnaire according to expert opinions, which ensured the rationality of the questionnaire items. In this study, statistical methods such as discrimination analysis method, correlation coefficient analysis method and internal consistency reliability analysis method were used to screen the questionnaire items, try to avoid the deviation caused by the selection of items by a single method, and ensure the representativeness and reliability of the questionnaire items. Sensitivity. In this study, the questionnaire was pre-investigated to test its reliability and validity, which ensured the stability and validity of the structure and content of the questionnaire. 15 Year Global Journal of Medical Research Volume XXIII Issue I Version I ( D ) 2023 J © 2023 Global Journals Development of Knowledge-Attitude-Practice Questionnaire on Oral Nutrition Supplement among Nurses in Oncology Department and its Reliability and Validity Test
