Abstract: Objective: To translate and cross-culturally adapt the health education impact Questionnaire (heiQ) into Chinese and test its reliability and validity among patients with chronic diseases. Methods: The Chinese version of heiQ (heiQ-C) was developed in strict accordance with the Translation Integrity Procedure after the author's authorization, and 413 patients with chronic diseases were included from a tertiary grade A hospital in Shanghai to test its reliability and validity by convenience sampling. Results: The heiQ-C consisted of 40 items and 8 subscales. The Content Validity Index of the Scale (S-CVI/Ave) was 0.956, and the Content Validity Index (CVI) of each item ranged from 0.880 to 1.000. According to the structure of the original scale, the confirmatory factor analysis results of the heiQ-C showed that the modified eight-factor model fitted well with good model fitting index. The Cronbach's α coefficient of the whole heiQ-C was 0.840, and for each subscale ranged from 0.714 to 0.900. The overall composite reliability of the heiQ-C was 0.810, and for each subscale ranged from 0.750 to 0.895. Conclusion: The heiQ-C has good reliability and validity among patients with chronic diseases, and it can be used to evaluate health education impact for patients with chronic diseases in China.
