Abstract:
Objective:To develop a nutritional assessment scale for patients with inflammatory bowel disease and examine its reliability and validity for assessing nutritional literacy in patients with inflammatory bowel disease.Methods:Based on the Nutbeam health literacy stratification model and knowledge-attitude-practice model, a preliminary scale was developed through literature review, semi-structured interviews, expert consultation and pre-surveys. A convenient sampling method was used to select 376 inflammatory bowel disease patients admitted to Tenth People′s Hospital Affiliated to Tongji University from September, 2022 to April, 2023 for questionnaire surveys, and reliability and validity tests were conducted to form the final scale.Results:The nutritional assessment scale for inflammatory bowel disease included 39 items. Exploratory factor analysis identified five common factors: nutritional knowledge, nutritional attitudes, nutritional practices, information interaction ability, and information evaluation ability. These factors explained 65.431% of the total variance. The content validity index of the scale was 0.857, and the item-level content validity index ranged from 0.800 to 1.000. The Cronbach α coefficient of the scale was 0.869, and the Cronbach α coefficients of each dimension ranged from 0.847 to 0.922. Conclusions:The developed nutritional assessment scale for inflammatory bowel disease demonstrates good reliability and validity, allowing for effective evaluation of patients′nutritional status.
