First, literature review, brainstorming, delphi study, and pr-survey were used to construct draft of the nutrition literacy scale for patients with gout. Second, 526 patients with gout underwent scale-based surveys. Item analysis and exploratory factors were used to optimize the scale. Confirmatory factor analysis was used to verify the structure of the scale, including the goodness of fit of the model, convergent validity, and discriminant validity. Subsequently, the reliability of the scale was tested using cronbach\u2019s \u03b1 coefficient and test-retest reliability.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec033\">\n<jats:title>Results<\/jats:title>\n<jats:p>The formal scale contains 5 dimensions: nutrition belief, nutrition knowledge, nutrition information acquisition ability, nutrition information interaction ability, nutrition information criticism ability, and 26 items. The overall content validity of the scale is 0.933. Exploratory factor analysis extracted 5 factors with a cumulative variance contribution of 82.18%. Confirmatory factor analysis showed that the scale structure was well fitted, with good convergent and discriminant validity. The overall cronbach\u2019s \u03b1 coefficient of this scale was 0.873, and the cronbach\u2019s \u03b1 coefficients of the dimensions were 0.861\u2009~\u20090.980, and the overall re-test reliability was 0.864, and the re-test reliabilities of the dimensions were 0.881\u2009~\u20090.981.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec034\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>Nutrition Literacy Scale for Gout Patients has good reliability and validity.
