Abstract
BACKGROUND
Rumination increases vulnerability to depression, exacerbates and perpetuates negative moods. This study was aimed to examine the psychometric properties of the Chinese version of the 10-item Ruminative Response Scale (RRS-10) in a large undergraduate sample.

METHODS
A sample of 5,236 university students finished the RRS and the Center for Epidemiological Studies Depression Scale (CES-D). Confirmatory Factor Analysis (CFA) was performed to examine the two-factor structure and the measurement equivalence of the RRS-10 across gender. The internal consistency, test-retest reliability, correlations among RRS, RRS-10 and CES-D were also explored. In addition, gender difference on rumination and the relationship between rumination and depression were further investigated.

RESULTS
The two-factor model of RRS-10 fit the data reasonably and had acceptable internal consistency and test-retest reliability in Chinese undergraduates sample. And the measurement equivalence of the RRS-10 was acceptable across gender in Chinese university students. Findings in respect of latent means and manifest means revealed non-significant gender difference in RRS-10. Besides, participants with high-level rumination had more depressive symptoms than those with low-level rumination.

CONCLUSIONS
The Chinese version of the RRS-10 showed good psychometric properties and was measurement invariant across gender in undergraduates.
