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

Abstract

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.
