Abstract

Objective: To translate and validate the Post-Intensive Care Syndrome (PICS) Questionnaire for use in Chinese ICU patient populations.

Methods: Authorization was secured via email from the original author of the questionnaire. Utilizing the Brislin translation model, the questionnaire underwent Sinicization and cultural adaptation to develop the initial Chinese version. A survey was carried out among 278 patients who were discharged from ICU in a tertiary hospital in China. The reliability and validity of the Chinese PICS questionnaire was then assessed.

Results: The Item Content Validity Index (I-CVI) ranging from 0.84 to 1.0, the Scale Content Validity Index (S-CVI) of 0.92, the Cronbach's α coefficient of 0.903, and the split-half reliability greater than 0.8. The exploratory factor analysis indicated three dimensions with 18 items. The cumulative variance contribution rate was 68.445%. The confirmatory factor analysis results indicated good model fit.

Conclusion: The Chinese version of the PICS questionnaire exhibits robust reliability and validity, confirming its suitability for assessing Post-Intensive Care Syndrome in Chinese ICU patients.

Keywords: Assessment tool; Post-Intensive care syndrome; Reliability; Validity.
