The Emotion Regulation Questionnaire (ERQ; Gross & John, 2003) assesses two emotion regulation (ER) strategies: cognitive reappraisal and expressive suppression. Researchers have used the ERQ in cross‐national studies, such as with participants in Hong Kong. There is inconsistency in psychometric equivalence data for the ERQ in Chinese among adults, and prior research in Hong Kong contradicted the ERQ’s original factor structure (Matsumoto et al., 2008). The present study examined the factor structure, reliability and validity of a translated Traditional Chinese‐ERQ and the English‐ERQ with Hong Kong college students. Results revealed that both versions replicated the original two‐factor structure of the ERQ (Gross & John, 2003). Evidence of the measure’s convergent, discriminant and predictive validity was obtained as well. Implications for cross‐cultural scale validation particularly with Hong Kong Chinese students are discussed.
