Abstract:

Objective To translate the Insulin Treatment Self-Management Scale（IT-SMS） into Chinese and test its reliability and validity in the Chinese context，providing a scientific assessment tool for self-management of insulin therapy among diabetic patients in China. Methods The original IT-SMS was translated into Chinese using the Brislin translation model. Following cross-cultural adaptation and a pilot survey，the Chinese version of the IT-SMS was developed. From October 2023 to March 2024，a questionnaire survey was conducted using a general demographic questionnaire and the Chinese IT-SMS among diabetic patients undergoing insulin therapy who were conveniently sampled from the endocrinology department of a tertiary hospital in Shanghai. Reliability and validity of the Chinese IT-SMS were assessed. Results The Chinese version of the IT-SMS contained 31 items in four dimensions，namely，behavior（8 items），cognition（10 items），emotion（8 items），and attitude（5 items）. The I-CVI of the scale was 0.833-1.000，and the S-CVI was 0.974. Four common factors were extracted by exploratory factor analysis，and the cumulative variance contribution rate was 59.902%. The total Cronbach’s α coefficient of the Chinese version of IT-SMS was 0.928，the test-retest reliability coefficient was 0.883，and split-half reliability coefficient was 0.763. For the four dimensions，Cronbach’s α coefficients ranged from 0.873 to 0.919，test-retest reliability coefficients from 0.819 to 0.875，and split-half reliability coefficients from 0.858 to 0.923. Conclusion The Chinese version of IT-SMS has good reliability and validity，and is applicable to the evaluation of insulin treatment self-management among Chinese diabetic patients.
