The Essential Resilience Scale (ERS) is a locally developed measure conceptualized by Chinese researchers and demonstrated strong psychometric properties in Chinese residents.

Abstract
The Essential Resilience Scale (ERS) is a locally developed measure conceptualized by Chinese researchers and demonstrated strong psychometric properties in Chinese residents. To date, no study has tested the adaptation of the ERS in another culture and measurement equivalence of the locally developed Chinese ERS and the English adaptation proposed by Chen and colleagues (2016). Thus, the present study aims to contribute to the literature through (1) assessing the psychometric properties of the Chinese and English versions of the ERS using item response theory (Stage 1), testing the measurement equivalence of the Chinese and English version of the ERS using differential item functioning (Stage 2), and establish its criterion validity through the associations with the Resiliency Scale for Young Adults (RSYA) and Satisfaction with Life Scale (SWLS; Stage 3). Undergraduate students from China (N=375) and Canada (N=378) were recruited to complete the ERS and criterion validity measures (i.e., Resiliency Scale for Young Adults, Satisfaction with Life Scale). The item response theory parameterization using Samejima’s (1969) graded response model showed discrimination parameters ranged from 1.02 to 2.22 and 0.32 to 1.97 in the Chinese and English versions, respectively. Differential item functioning (DIF) analyses showed six of 15 items were flagged for DIF; five of these items showing nonuniform DIF revealed more discriminant items for the Chinese version compared to the English version. Cross-cultural comparisons using the ERS could present biases if not corrected for DIF. Finally, both the Chinese and English versions of the ERS were associated with Resiliency Scale for Young Adults subscales and satisfaction with life in the expected directions. Although, the Chinese version of the ERS demonstrated strong psychometric properties, the present results suggest its English counterpart may not be a suitable measure for resiliency. This study contributes to existing research in examining trait resilience with a locally developed measure in China and emphasized on the importance of evaluating measurement equivalence cross-culturally whenever adapting a measure for use with another cultural, linguistic, or unique group.
