Objective To develop a health literacy scale for patients after weight loss metabolism surgery and test its reliability and validity. Methods The initial version of the scale was constructed after literature review, semi-structured interviews, expert inquiries, and pre-surveys. Then 278 postoperative patients undergoing weight loss and metabolism surgery in gastrointestinal departments of two grade-A tertiary hospitals in Hubei province between December 2023 and April 2024 were selected and surveyed. Thus, the reliability and validity of the scale were tested. Results The scale constructed included three dimensions of health knowledge and concepts, healthy lifestyle and behavior, and health skills, covering 20 items. The content validity of the scale is 0.824, and that of the items of 0.835~0.882. Moreover, the total Cronbach′s alpha, the half fold reliability and the test-retest reliability of the scale was 0.856, 0.894 and 0.911, respectively. Exploratory factor analysis extracted three co-factors, with a cumulative variance contribution rate of 67.65%. Conclusion The health literacy scale for post weight loss metabolic surgery patients is scientific and practical, with good validity and reliability, which can provide guidance for the evaluation of health literacy in post weight loss metabolic surgery patients.
