Psychometric properties and measurement invariance of the Chinese version of the cognitive emotion regulation questionnaire‐short in patients with cancer.

Objective: The study aimed to evaluate the psychometric properties and measurement invariance (MI) of the Chinese version of the cognitive emotion regulation questionnaire‐short (CERQ‐short) in cancer patients. Methods: This cross‐sectional study included 505 cancer patients from mainland China. In addition to sociodemographic and clinical characteristics, the CERQ‐short and the distress thermometer were included in the study measures. Results: Item analysis indicated a promising result. And the results of CFA indicated that the CERQ‐short demonstrated satisfactory factorial validity in cancer patients. Cronbach's alpha coefficients were between 0.663 and 0.910, while McDonald's omega coefficients were between 0.664 and 0.910. The CERQ‐short had sufficient convergent, discriminant and concurrent validity among cancer patients. Lastly, MI supported that the CERQ‐short demonstrated strong measurement equivalence across gender, residence and age. Conclusions: This study shows that the Chinese version of the CERQ‐short has convincing psychometric properties and MI, which supports its use in cancer patients. [ABSTRACT FROM AUTHOR]
