Cultural Adaptation and Psychometric Evaluation of the Preference for Intuition and Deliberation in Eating Decision-making Scale among Chinese People with Cardiovascular Disease

Abstract Background Healthy diet plays a critical role in the prevention, treatment, and prognosis of cardiovascular disease. The Preference for Intuition and Deliberation in Eating Decision-Making Scale (E-PID) was developed to evaluate individuals' preferences for intuitive and deliberative styles when making dietary decision. Our study aims to culturally adapt it into Chinese and test its psychometric properties in 1463 people with cardiovascular disease (CVD). Methods The original E-PID was translated into Chinese using the Brislin translation model. 1463 patients were recruited from a hospital from July 2024 to December 2024. The psychometric properties of the Chinese version of the E-PID were assessed through item analyses, composite reliability, test re-test reliability, measurement invariance (MI), factorial validity, discriminative validity and criterion-related validity. Results Item analyses indicated that no item deletion was necessary. Both exploratory factor analysis (EFA) and exploratory graph analysis (EGA) (n = 704) supported the two-factor structure of the 7-item original scale, and confirmatory factor analysis (CFA)indicated that the scale demonstrated a satisfactory model fit. Psychometric properties showed strong internal consistency, sufficient criterion-related validity and test-retest reliability over a six-week period. The results also demonstrated that the Chinese version of the E-PID maintained good measurement properties across gender, supporting its applicability for examining gender-related differences. Conclusion The E-PID showed sufficient psychometric properties in a Chinese sample, making it a valid instrument for assessing dietary decision-making preferences among people with cardiovascular disease in China and can serve as an effective tool for both clinical practice and research.
