Development of Knowledge-Attitude-Practice Questionnaire on Oral Nutrition Supplement among Nurses in Oncology Department and its Reliability and Validity Test Yanan Li α , Lu Wang σ , Zhiping Chu ρ & Xiumei Yang Ѡ Abstract- Objective: To develop a questionnaire on oncology nurses’ knowledge-attitude-practice towards oral nutrition supplementation, and to test its reliability and validity. Methods: Based on literature review and Delphi expert correspondence, the initial questionnaire was constructed on the basis of knowledge-attitude-practice mode. A total of 265 oncology nurses from 5 tertiary care hospitals in Jiangsu Province were selected by convenience sampling method for pre-survey to test the reliability and validity of the questionnaire and form the final version. Results: The questionnaire included three dimensions: knowledge, attitude and practice, with a total of 43 items; exploratory factor analysis extracted a total of five common factors, with a cumulative variance contribution rate of 81.087%; confirmatory factor analysis results showed that the model fitted well. The scale-level content validity index of the questionnaire was 0.914, and the item-level content validity index ranged from 0.832 to 1.000; the Cronbach’s α coefficient of the questionnaire overall was 0.958, and the test-retest reliability was 0.978. Conclusion: The questionnaire on knowledge-attitude-practice of oral nutrition supplement knowledge among oncology nurses has good reliability and validity. It can be used as an evaluation tool for the level of knowledge-attitude-practice of oral nutrition supplement knowledge of oncology nurses. Keywords: nurses; oral nutritional supplements; knowledge-attitude-practice; reliability; validity. I ntroduction ancer patients often suffer different degrees of malnutrition, which affect the function of body tissues and organs, resulting in a decrease in the patient's tolerance to treatment and the curative effect of tumor treatment, thereby affecting the quality of life and prognosis of patients [1]. Therefore, for cancer patients, nutritional therapy is an essential part of comprehensive cancer therapy. Oral nutritional supplements (ONS) are formulas (foods) for special medical purposes that are ingested orally to supplement insufficient daily diet, and meet the body's nutritional needs by providing nutrients such as carbohydrates, proteins, and fats [2]], is the Author α σ ρ : Nursing department, The Second Affiliated Hospital of Nanjing Medical University, Nanjing 210000, China.

ONS can improve the nutritional status of cancer patients, prevent malnutrition and its complications, and enhance anti-tumor efficacy [4]. As the nurses who are most closely contacted during the inpatient treatment of cancer patients, their cognitive and behavioral levels of ONS will affect the patient's compliance with ONS and the effect of nutritional therapy [5]. An evaluation tool for ONS knowledge, belief, and behavior by nurses. Therefore, by compiling a questionnaire on ONS knowledge, belief, and behavior of oncology nurses and testing its reliability and validity, this study provides an evaluation tool for evaluating the status quo of ONS knowledge, belief, and behavior among oncology nurses, and provides targeted training programs and scientific management strategies. I. R esearch M ethodology Compile the ONS Knowledge, Credit and Action Questionnaire a) Setting up a research group The research group consisted of 6 members who were familiar with the research contents, including 2 chief physicians of the oncology department, 2 deputy chief nurses and 2 nursing master students. The members of the group are responsible for the formulation of the initial items of the questionnaire, carrying out inquiries from Delphi experts, pre- investigation of the initial questionnaire, and data collection, arrangement and analysis. b) Compile the initial item pool of the questionnaire This study is based on the knowledge, belief, and action model [6]. The research team discussed the major and difficult issues related to ONS in cancer patients, followed the best evidence for the implementation and management of ONS in patients with malignant tumors summarized by Zhu Yunxia et al. The initial item pool for the questionnaire. The formed questionnaire item pool includes a total of 51 items, including 12 knowledge dimensions, 16 belief dimensions, and 23 behavior dimensions, mainly C 9 Year Global Journal of Medical Research Volume XXIII Issue I Version I ( D ) 2023 J © 2023 Global Journals
