content validity of the questionnaire; Cronbach's alpha coefficient and test-retest reliability coefficient were used to test the reliability of the questionnaire. P<0.05 was considered to be statistically significant. II. R esults a) General information on nurses A total of 265 valid questionnaires were collected in this study. All of the 265 nurses in the oncology department were female; age ranged from 22 to 49 (33.52±6.80) years; education: 22 (8.30%) junior college, 236 undergraduate (89.06%), and 7 master (2.64%); work in oncology 2-18 (11.31±6.37) years; professional title: 74 (27.92%) with primary professional title, 165 (62.26%) with intermediate professional title, 26 (9.81%) with senior professional title; 32 (12.07%) of specialist oncology nurses; 109 cases (41.13%) had participated in ONS-related knowledge and skills training. b) Project Analysis Results i. Discrimination analysis method After the total score of the questionnaire was sorted from low to high, the total score of the 72nd and 193rd subjects was the critical value, and the total score ≤ 134 was divided into the low group, and the total score ≥ 183 was divided into the high group. There was no significant difference in the items K3 (CR=1.025), K4 (CR=2.673), and K11 (CR=1.628) between the two groups (P>0.05). These three items were deleted. The CR values of the remaining items ranged from 4.366 to 12.758 with P<0.05. ii. Correlation coefficient analysis method The correlation coefficients of items K3, K4, K11 and the overall questionnaire are 0.108, 0.366 and 0.136, respectively, and the correlation coefficients with their knowledge dimensions are 0.215, 0.377 and 0.283, all <0.40, indicating that these three items are homogeneous with the questionnaire. Poor performance, consider deleting it. The correlation coefficients of the remaining items with the overall questionnaire ranged from 0.514 to 0.882, and the correlation coefficients with their knowledge, belief and behavior dimensions were 0.543 to 0.717, 0.577 to 0.748, and 0.754 to 0.893, respectively. iii. Internal consistency reliability analysis method The Cronbach's alpha coefficients of the questionnaire population, knowledge dimension, belief dimension and behavior dimension were 0.958, 0.862, 0.942 and 0.972, respectively. After removing a certain item, the Cronbach's alpha coefficients of the questionnaire population, knowledge dimension, belief dimension and behavior dimension were 0.765~0.911, 0.711~0.817, 0.793~0.887 and 0.823~0.925, respectively. None of the Cronbach's alpha coefficients increased, indicating that each item made a greater contribution to the internal consistency of the questionnaire, and no item was deleted. c) Validity analysis results i. Construct validity a. Exploratory factor analysis In this study, KMO=0.821, and the Bartlett test of sphericity was statistically significant (x2 =9427.980, P<0.001), which was suitable for factor analysis. Factor loadings of 0.337 and 0.289 for entries K2 and K5, respectively, were removed after the variance- maximizing orthogonal rotation. After the entry was deleted, the second exploratory factor analysis was performed, KMO=0.830, and the difference was statistically significant (x2 =4910.303, P<0.001); 5 common factors with eigenvalues>1 were extracted, and the cumulative variance contribution rate Among the five common factors, common factors 1 and 2 are classified as behavior dimensions, common factors 3 and 5 are classified as belief dimensions, and common factor 4 is classified as knowledge dimension, which is basically consistent with knowledge. The theoretical framework of Xinxing. The final questionnaire includes 43 items, including 8 items in the knowledge dimension, 13 items in the belief dimension, and 22 items in the behavior dimension. See Table 1 for details. The results of the exploratory factor analysis are shown in Table 2. Table 1: Items of ONS Knowledge, Attitude and Action Questionnaire for Oncology Nurses. Questionnaire Entries for Dimensions Knowledge K1: For cancer patients with normal gastrointestinal function, the preferred way to receive enteral nutrition is K6: When the oral intake of tumor patients during the perioperative period is less than the recommended target calories and protein, ONS should be given before surgery K7: Symptoms of oral enteral nutrition intolerance mainly include K8: The highest goal of nutritional support treatment for cancer patients is The principles of K9: ONS include K10: Before the implementation of ONS, in addition to fully assessing the nutritional status of the patient, a comprehensive assessment of the patient’s general condition should be carried out, including K12: When taking ONS for patients with oral mucositis, what ways can be used to reduce the pain caused by ONS stimulation of the mucous membrane? 12 Year Global Journal of Medical Research Volume XXIII Issue I Version I ( DD ) 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
