Abstract:
Objective:To develop the Nutrition Knowledge, Attitude and Practice Questionnaire for Maintenance Hemodialysis (MHD) Patients and test its reliability and validity.Methods:This is a cross-sectional study. Based on the theory of knowledge, attitude and practice, and on the basis of literature analysis, semi-structured interviews and expert focus interviews, an initial questionnaire was formed through Delphi expert consultation and pre-survey. In July 2020, 200 patients with MHD were selected from the Blood Purification Center of Lu'an Hospital of Anhui Medical University by convenient sampling to carry out the first round of questionnaire survey and conduct item analysis of the questionnaire. In August 2020, 230 MHD patients were selected from 6 other Hemodialysis Centers in the same city by convenient sampling to carry out the second round of questionnaire survey and evaluate the reliability and validity of the questionnaire. In the first round of questionnaire survey, a total of 200 questionnaires were distributed, and 183 valid questionnaires were recovered, with an effective recovery rate of 91.50% (183/200) . In the second round of questionnaire survey, 230 questionnaires were distributed and 214 valid questionnaires were recovered, with an effective recovery rate of 93.04% (214/230) .Results:The formal questionnaire included 29 items in three dimensions of knowledge, attitude and practice. The total Cronbach's α coefficient of the questionnaire was 0.853, and the retest reliability coefficient was 0.880. The item-level content validity index of the questionnaire was 0.910 to 1.000. Exploratory factor analysis extracted 9 common factors, and the cumulative variance contribution rate was 62.89%. The confirmatory factor analysis showed that the fitting index of the model was ideal, the composite reliability in the convergent validity was more than 0.700, the correlation coefficient of the discriminant validity was positive and less than 0.500, less than the square root of average variance extracted, and the discriminant validity was good.Conclusions:Nutrition Knowledge, Attitude and Practice Questionnaire for MHD Patients has good reliability and validity, and can be used as a reliable tool to evaluate the nutrition knowledge, attitude and practice of MHD patients in China.
